HORIZON OVERVIEW
The ESTeem Horizon is a series of wireless LAN
transceivers that can be used to build many types of
Wireless Local Area Networks (WLAN). The
wireless modems in Horizon series can provide RF
data rates up to 150 Mbps and have an RS-232
serial port for legacy device networks. The Model
Horizon is a very sophisticated networking device
that can be configured for multiple modes of
operation depending upon the needs of the wireless
and wired LAN system.
The following
configuration modes are provided as an overview
of the basic network types, as all possible network
configurations cannot be listed. For further help in
selecting the correct network type, please refer to
Chapter 4 of this User’s Manual or call Customer
Support at 509-735-9092.

INTRODUCTION
CONFIGURATION MODES
The Horizon can be configured for multiple
modes of operation without any changes to the
hardware. The following are brief descriptions
of the configuration modes. For detailed
descriptions and suggested applications for each
mode, please refer to Chapter 4.
Access Point Modes
When the Horizon is configured as an Access
Point it will provide a wireless bridge for mobile
clients such as Horizon or Model 195E modems
in client modes or Wi-Fi devices. Multiple
Access Points can be physically connected to the
same network (LAN) or through a radio link
using the Access Point Repeater mode to
provide overlapping, seamless Ethernet
communication for mobile devices.
1.
Access Point Bridge Mode
Figure 3: Repeater Mode Diagram
An ESTeem Horizon in Access Point Bridge mode will both provide wireless access to mobile clients (Access Point) and
bridge all Ethernet data connected to the Ethernet ports. The AP Bridge mode will pass all network traffic between
connected devices including global network broadcasts. (See Figure 2)
2.
Access Point Router Mode
In this mode the ESTeem Horizon will function as a router between wired Ethernet networks, connected to the Horizon’s
Ethernet port, and the wireless clients in the network. As in all standard router configurations, the wireless and wired
Ethernet networks will need to be on
separate subnets. The Horizon in
Access Point Router mode will pass
network traffic for connected devices
but will block global network
broadcasts from the wired network.
This mode of operation should be
used instead of the Access Point
Bridge mode when a separation
between networks is required or the
ESTeem is connected to larger LAN
Networks that will continuously send
global network broadcasts (Figure 3).

EST P/N AA107-Horizon
CHAPTER 1
INTRODUCTION
3.
Access Point Masquerade Mode
The Access Point Masquerade mode is a special use of the Access Point mode where the Horizon will connect mobile
clients into a single static IP address on a wired network. Data requests from the wireless network will be processed
through the Access Point Masquerade modem, but any request from the wired Ethernet network to devices on the wireless
network will be rejected similar to the operation of a “firewall”. The Horizon will hide all the IP addresses connected on
the wireless link. You would use this mode of operation if Horizon is connected directly to the Internet with a static IP
address (DSL, T1, etc.) and you want the wireless clients to access the information through the Horizon (Figure 4). This
mode should also be used for attaching the Horizon to a network where few IP addresses are available or a firewall for the
wireless clients is required.
Access Point Repeater
The Access Point Repeater is a unique enhancement of the ESTeem Horizon series. The Access Point Repeater can be
used with any of the above Access Point modes. With this repeater feature enabled, the Access Points do not have to be
hardwired together on the same physical LAN to provide seamless Ethernet communication for roaming clients. In addition
to greatly extending the Access Point canopy range, the Horizon will also bridge any Ethernet device or Ethernet network
connected to the unit over this same wireless Ethernet network. This mode gives the user the features of a point to multipoint bridge network but also allows the Horizon in the Client mode to simultaneously roam under the network canopy.
Self-Healing Mesh Network
If multiple Access Point Repeater routes are configured to the same destination ESTeem, the Horizon will create a “selfhealing” mesh network by automatically re-routing data through alternate paths to reach its destination if the primary
path is inoperable. The routing and priority of alternate paths is completely user configurable. (See Figure 5)

CHAPTER 1
INTRODUCTION
Station (Client) Modes
1.
EtherStation Mode
When the Horizon is configured in the EtherStation mode and attached to a single Ethernet Device, the Horizon will
emulate an 802.11 wireless card in functionality for communication as a mobile client. The Horizon will seamless roam
under the radio canopy of Access Points and can provide greatly increased range over a Wireless LAN Card for mobile
Ethernet devices such as vehicles, forklifts, cranes, etc (Figures 2-4).
2.
Station Router Mode
The Station Router mode will also functions as a mobile client, similar to EtherStation, but will allow multiple Ethernet
devices to be connected to a single Horizon (Figure 4). The Horizon will function as a router between the wireless client
mode and the wired Ethernet devices connected to the Ethernet port. Similar in configuration to the Access Point Router
mode, the wireless and wired Ethernet networks will need to be on separate subnets. To communicate from wireless
network to devices on the wired Station Router network, a separate router (connected to the Ethernet side of the Access
Point) is required. This mode would be used where multiple Ethernet devices will be connected to a single Horizon in a
mobile client application and the connected Ethernet devices will need to be accessible from the Access Point’s LAN
network.
3.
Station Masquerade Mode
The Station Masquerade mode is another case multiple devices will be connected to a single ESTeem in a mobile or client
application. However, unlike the Station Router mode, the Station Masquerade will consolidate all connected Ethernet
devices to a single IP address on the network. The devices connected to the Station Masquerade will be able to access
information from both the wireless and wired LAN, but will be inaccessible the other way similar in application to a
firewall. This mode would be used where multiple Ethernet devices will be connected to a single Horizon in a mobile
application and the IP addresses for each device will be hidden from the LAN connected to the AP. See Figure 4.

INTRODUCTION
RS-232 Serial Applications
The ESTeem Horizon is installed with an RS-232 data port for serial data applications run over the broadband link (Figure
6). The serial over broadband network can be used in a point-to-point or point-to-multi-point application for networking
serial (RS-232C) devices, providing serial connections to legacy hardware in a new Ethernet network or providing for
high-bandwidth devices (such as Video or Voice over IP) in an existing serial network.

CHAPTER 2
STARTING OUT
OVERVIEW
There are three main phases to prepare the ESTeem Horizon for operation in a wireless network:
Phase 1 - Determine the correct mode of operation for the Horizon in the wireless network. The ESTeem Horizon is a
sophisticated networking device that can be configured for multiple modes of operation. Determining the correct mode of
operation for the ESTeem Horizon is the first step. Chapter 3 of this User’s Manual details the modes of operation and
applications where each would be used.
Phase 2 - Program the ESTeem for operation in the wireless network. Once the correct mode of operation for the ESTeem
has been determined, the Horizon can be programmed for the wireless network. To simplify the programming of the Horizon,
ESTeem has created a new software utility called the ESTeem Network Configuration (ENC) Utility which is used to graphically
configure the primary and backup communication routes between radio modems in the network. The ENC Utility can be installed
from the ESTeem Resource Disk or from the ESTeem web site (www.esteem.com). Chapter 4 (Utilities and Features) of this
User’s Manual will guide you in the installation of the software and give a brief overview of operation of the ENC Utility, but a
detailed User’s Guide is available both on the ESTeem Resource Disk and in the Help section of the program itself.
The ESTeem Horizon can also be programmed through the internal Web interface (discussed in detail in Chapter 5) if you do not
have access to the ENC Utility.
Phase 3 - Install the ESTeem hardware and test communication. After the ESTeem Horizon programming, install the
hardware in each remote location. Chapter 8 of this User’s Manual describes the antenna specifications, mounting options and the
configuration of the pole mounting hardware for the ESTeem. For instructions on testing and troubleshooting the wireless link,
refer to Appendix F (Troubleshooting).
MODEL 195E HARDWARE LAYOUT
To begin the configuration, unpack the ESTeem Horizon shipping boxes and locate the items below for initial configuration. Take
a few minutes to inventory your equipment before you proceed. Report any missing or damaged items to Customer Support (509735-9092) as soon as possible. Each node in your ESTeem Horizon’s network may have different hardware components based
upon the final installation location (i.e. Outdoor, Indoor, Point-to-point or Muti-Point). Antenna types, cable lengths, power
supplies may be different, but the following items will be required for basic setup:

EXAMPLE APPLICATIONS
MODES OF OPERATION
The ESTeem Horizon is a sophisticated wireless networking device that can be configured for multiple modes of
operation. Determining the correct mode of operation for the ESTeem is the first step in creating a reliable wireless
network. This chapter will explain each mode of operation, provide example applications and detailed programming
information for each mode. Please review the following modes of operations. If you do not see an example of your
application, please contact ESTeem support at 509-735-9092 for help in selecting your mode of operation.
Ethernet Bridge Mode (AP Bridge)
The most commonly used mode of operation with the ESTeem Horizon is the Ethernet bridge mode. The Ethernet
bridge mode will connect two or more ESTeem Horizon’s while passing all network traffic that arrives in both the
wireless and connected Ethernet ports; including all global network traffic (Figure 1). This mode will work in most
wireless applications of the Horizon to wirelessly connect two or more remote Ethernet devices or networks. The
Ethernet bridge mode is also used in repeating (Figure 2) and in self-healing Mesh networks (Figure 3) for fixed (non
mobile) applications.

EXAMPLE APPLICATIONS
Router Modes (AP Router and AP Masquerade)
The ESTeem Horizon can be configured as a network router or network firewall between the Ethernet LAN connection
and the wireless network of remote locations. The router modes are used to limit the network traffic from a busy
Ethernet network connection to only those specific IP address used on the wireless network (see Figure 4). The
Ethernet router mode (AP Router) will allow bi-directional communication from the Ethernet LAN connection to the
wireless network. The Ethernet firewall mode (AP Masquerade) will allow Ethernet devices in the wireless network
to request information from the Ethernet LAN network and receive a response, but no traffic can be generated from
the Ethernet LAN side.
Example Applications
 Wireless Ethernet networks connected to large company or plant Ethernet LAN networks (AP Router)
 Wireless Ethernet networks with a requirement for network isolation from the plant or company network
(AP Router)
 Shared Ethernet connection to direct Internet service (DSL, Cable, T1, etc.) (AP Masquerade)
Applications Where Ethernet Router Mode Not Used
 Mobile applications (see Mobile Clients)
 Simple network connections only using a single IP network subnet (see Ethernet Bridge modes)

CHAPTER 3
EXAMPLE APPLICATIONS
Mobile Client Modes (EtherStation, Station Router or Station Masquerade)
The ESTeem Horizon can also be configured to function as a mobile client. The client modes allow the Horizon to
seamlessly roam between fixed Access Points. These Access Points can either be ESTeem Horizon wireless
modems configured in one of the three Access Point modes (AP Bridge, AP Router or AP Masquerade – see above)
or any IEEE 802.11 (Wi-Fi). The client modes will allow mobile Ethernet devices to connect to each other or to an
Ethernet LAN through the fixed AP (Figure 5).
The EtherStation mode is used to connect a single Ethernet device to the ESTeem Horizon. If you are connecting
the Horizon to multiple Ethernet devices in a mobile mode, the Station Router or Station Masquerade will be required.
The Station Router will allow bi-directional communication between the Ethernet devices connected to the Horizon
and the wireless network, while the Station Masquerade will serve as a firewall on the Ethernet side.
Example Applications
 Mobile applications where the Horizon will change links often between fixed Access Points
 Long range mobile client networks
 Public safety applications for police, fire and EMS
Applications Where Mobile Client Mode Not Used
 Fixed locations using Ethernet Bridging or Routing
 Wireless Ethernet networks with repeaters

EXAMPLE APPLICATIONS
802.11 Access Point Modes (AP Bridge, AP Router or AP Masquerade)
The ESTeem Horizon can be configured as a high power 802.11 Access Point (AP). The IEEE 802.11n/g/b Access
Point (AP) functionality is available in all three of the Access Point modes (AP Bridge, AP Router or AP Masquerade).
The Access Point mode will provide either a single wireless connection (Figure 6) or overlapping coverage (Figure 7)
to create a “canopy” of wireless coverage for 802.11 devices. The ESTeem Horizon in AP mode can function as both
an Ethernet bridge or router and 802.11 AP simultaneously (Figure 8).
Example Applications
 Industrial, long range 802.11 (Wi-Fi) networks
 Hybrid networks of Ethernet bridging/routing and mobile client access
Applications Where Access Point (AP) Mode Not Used

PROGRAMMING EXAMPLES
Once the mode of operation for the ESTeem has been
determined, you are now ready to program the Horizon for use.
ESTeem has created a simplified network programming utility call
the ESTeem Network Configuration (ENC) Utility. This ENC
Utility will be used in all the following programming examples. For
detailed instructions on installing the ENC Utility, please refer to
the User’s Guide (found in the ESTeem Resource CD or Utility
program itself) or Chapter 4 of this User’s Manual
Technical Tip: The ENC Utility calculates the
wireless link information based upon exact
ESTeem serial numbers. The serial numbers
listed in the following examples are for example
only. Enter the correct ESTeem serial numbers
for your application.
Adding Esteem’s to ENC Utility and Changing Name
Each of the example applications will use the following procedure to add and rename ESTeem Horizon’s.
1.
Consult the ENC Utility’s User Guide on how the create a new wireless network. Once you have a blank network
configuration page (Figure 9), select ESTeem from the menu items to display the drop down menu, then select
New>New ESTeem.

Setting the ESTeem for Mobile Client (station) mode with the ENC Utility is different than
the Bridge/Router or Access Point (AP) modes. ESTeem modems configured in as a
Mobile Client will not link with a specific fixed modem; but will roam between any 802.11
Access Point with the correct Network Name (SSID) and Encryption. The ESTeem
configured as a client is also not set on a specific operating frequency (channel) but will
scan all channels looking for the AP. Use the following procedure to configure an ESTeem
Horizon in one of the three mobile client modes:
1.
Starting a new network of ESTeem Horizons in
Mobile Client mode is the same as any of the
Bridge modes except when you are asked for the
frequency (channel) of operation, select “Station”
(Figure 23).
2.
Add the three mobile client modems to the ENC
Utility configuration page as instructed above and
set the Modem ID to match the three modes of
operation. Your configuration will appear as in
Figure 24.
Technical Tip: The ESTeem Horizon’s in
Mobile Client modes do not have a specific
frequency of operation as can be seen in Figure

By default, the ENC Utility sets all station mode ESTeem
modems to EtherStation mode.
The only adjustment
necessary to the EtherStation modem in our example is to
enter the connected Ethernet device’s MAC address. The
ESTeem Horizon will “clone” the Ethernet MAC address of
the connected Ethernet device.

UTILITIES & FEATURES
IGMP SNOOPING
Internet Group Management Protocol (IGMP) Snooping allows the ESTeem 195E to operate more efficiently in networks
with high Multicast (UDP, etc.) traffic. IGMP Snooping will define the destination for the Multicast traffic and send the
data to the correct wireless Ethernet modem, not the entire network. This limiting of Multicast traffic to specific
destinations greatly increases the overall network efficiency.
The problem with using multicast traffic over a wireless connection is that multicast packets do not require an
Acknowledge on the protocol layer. If the wireless network misses a data packet on the RF network, that multicast data
packet is lost.
Theory of Operation
There are two types of Ethernet packets on a network, unicast and multicast. Unicast is intended for exactly one
recipient (and ignored by all others). Multicast is intended to be received by multiple recipients. Interested parties can
listen for particular multicast packets, but most nodes ignore it. In any case, the network medium is still utilized no
matter how many nodes are listening. Broadcast packets are a special type of multicast traffic which all nodes always
receive. These are particularly useful for global announcements (Hey, I'm Alice!) and queries (Hey, I'm Alice and I'm
looking for Bob!). More relevantly, it is how hosts on a network find out each other's addresses, and are absolutely
crucial to the proper functioning of a network.
As the network grows physically, it encounters some growing pains. The first is more physical, relating to the cabling
limitations. Bridges solve this problem by joining two physical networks together so they appear to be a single large
network. Through use of bridges, a network can scale to hundreds or even thousands of hosts. There is a downside,
however. Well before the physical limitations of bridging hit, you start to run into efficiency problems, as all traffic has
to travel everywhere on the network. The raw carrying capacity of this shared medium, often referred to as bandwidth,
is the second scaling problem.
Smart bridges, or switches, help alleviate the bandwidth problem by only passing traffic across the bridge if the
destination host was on the other side. This greatly increases the capacity and efficiency of the network by allowing
two pairs of hosts communicating simultaneously on each side of the switched bridge. Only when the packet needs to
go to the other side is both mediums utilized simultaneously for the same packet.
Unfortunately, broadcast and multicast traffic by its very nature must always be relayed across the bridge. While the
number of network nodes may grow linearly, the multicast traffic tends to grow exponentially. This isn't generally a
problem for wired networks, as they have a considerable amount of bandwidth to spare, but wireless networks have, at
best, an order of magnitude less bandwidth to begin with. If a wireless network is bridged with a wired network, while
the absolute numbers are the same, a much higher proportion of the wireless network’s available bandwidth is used up
by multicast traffic. This effect is further magnified if multiple wireless repeaters are in use.
The preferred way of dealing with excess multicast traffic is to put the wireless network on a different sub-network
(subnet) and use a router to join it to the wired network. This ensures that only unicast traffic intended for the wireless
network crosses over, as multicast and broadcast traffic stays within its local subnet. Normally this is fine, but there are
times where you need multicast traffic to span subnets. For IP traffic, this can be obviated by using a multicast-capable
router, but for legacy multicast protocols that were not designed to be routed, another solution must be found.
There are two primary types of communication networks used in wireless Ethernet systems; fixed points communicating
to each other through an Ethernet Bridge and mobile devices communicating to these fixed points. The fixed point
Ethernet bridge communication in the 195E is through Repeater Peer links, while the mobile communication is from the
Client modes (EtherStation, Station Router and Station Masquerade) to the Access Points (Fixed Locations) in the
network. Each of these networks handles Multicast traffic differently as explained below.

UTILITIES & FEATURES
Ethernet Bridge Mode (Repeater Peers)
When the ESTeem 195E is configured as a repeater peer, all multicast traffic is “wrapped” in a Unicast frame and sent
to all other repeater peers. (Figure 14) This operation allows the ESTeem network to receive an acknowledge packet
and retransmit the data if the packet is lost during transmission. This unicast encapsulation will work regardless if the
protocol can support IGMP or not.

Ethernet Bridge Mode (Repeater Peers) With IGMP Snooping
When the ESTeem 195E is configured as a repeater peer, IGMP Snooping is enabled and the network supports IGMP
protocol, the 195E will begin to identify the connected Ethernet devices using Multicast transmissions and report this
information to the network. As this process continues, all sites that have Multicast traffic on the wireless network will
only send these requests to the specific ESTeem reporting the Ethernet device (see Figure 15).

Client Modes
When the ESTeem 195E is configured as a mobile client (EtherStation, Station Router or Station Masquerade), there
are two configurations that will increase the reliability of Multicast traffic. The first phase is encapsulation of the multicast
packets, as described in the Repeater Peer, and the second is IGMP Snooping if the network will support the protocol.
The encapsulation of the Multicast packets will operate regardless of the IGMP support to increase the reliability.

SERIAL APPLICATIONS
USING THE RS-232 PROGRAMMING PORT
Any terminal emulation program that can run with VT100 emulation can be used for this configuration of the ESTeem.
Most Windows users will probably use either Hyper Terminal or the Terminal Emulation in the ESTeem Utility program.
Configure your RS-232C port for a Baud Rate to 38,400, Data Bits to 8, Parity to None, Stop Bits to 1 and Handshaking
to None. Set the Emulation type to VT100. Once your ESTeem has an IP address, you can attach the ESTeem to your
network and use the Web Server for further programming.
Programming Using the RS-232 Port
1. When configuring the Horizon for the first time you can use the ESTeem RS-232C Configuration Menu to setup the
basic operating parameters such as assigning the IP Address, IP Net Mask, and Gateway IP Address.
2. Connect the serial cable (EST P/N: AA0621.1) between the RS-232 connector (RJ-45) on the Horizon’s
programming port to the serial port on the computer.
3. Plug the Model AA175 or AA175.2 power supply into a wall socket and connect an Ethernet patch cable from the
Horizon Ethernet port to the J1 (Data&PWR) port on the power supply. The Power over Ethernet (PoE) LED on the
front of the ESTeem should be illuminated.
4. If your computer is configured properly, you will see the ESTeem Horizon booting sequence on your Terminal
Emulation program. Once the ESTeem boot sequence is complete (approximately 45 seconds) you will receive this
message:
“Please press Enter to active this console.”
If you don’t see this message press the Reset button on the front panel of the Horizon and/or check the programming
of your RS-232 port.
5. Press the Enter key and you will be at the Configuration Menu Horizon login prompt. See Figure 1.
6. To enter the Horizon Main Menu you will need to log into the system with a login name and password.

SERIAL APPLICATIONS
USING THE RS-232 DATA PORT
The ESTeem Horizon has a serial data port that can provide RS-232 communication between two or more serial devices
using the wireless broadband link. The serial data is encapsulated and transferred as a standard Ethernet packet over
an operating Horizon wireless Ethernet system. The configuration for a serial Horizon network will be the same as an
Ethernet or a serial (RS-232) based communication network.
The serial interface option can be used to link two or more serial devices in a new or existing system. The serial data
has very little impact on the network bandwidth and will allow for both Ethernet and serial applications simultaneously.
A possible application would be installation of the Horizon in an existing serial based network that was looking for future
upgrade to an Ethernet based system. Another would be using the high-bandwidth Ethernet connections to provide a
link to remote video hardware while also providing a serial link to the existing PLC in a SCADA type application.
SERIAL CONNECTIONS
The RJ-45 serial data port is the far-left port on the face
of the Horizon (Figure 4). Using the ESTeem AA0621.1
interface cable, the Horizon can be connected to a
standard DTE-device (PC) with a male 9-pin Sub-D
connector.
The complete cable configuration is
available in Appendix C – Interface Ports.
SERIAL CONFIGURATION
Figure 4: Horizon Front Panel Overview
Configuration of the serial port is completed during the standard setup of the Horizon. After completion of the Repeater
Peer configuration screen, the Serial Port Setup screen (Figure 5) will be displayed. Each section in the Serial Port
Setup screen is described in detail with the following:
Enable the RS-232 Data Port
Enabling the serial data port allows the modem to send RS-232 data over the broadband wireless connection
established with the ESTeem repeater peers. The modem can be configured in a point-to-point or point-to-multipoint
system. Select Yes if you wish to enable the serial data port.
Mode of Operation
There are two distinct modes of operation for the serial port in the Horizon. The Redirector mode will provide two-way
serial communication between two or more serial devices, while the Terminal Server mode will allow serial
communication to a specific remote site by connecting through telnet or SSH. Select one of the following modes of
operation:
Full Redirector Mode - This mode allows bi-directional RS-232 data communication with other ESTeem Horizon’s. The
RS-232 data transmission will appear transparent to the connected devices as if a serial cable is connected between
the two ports. This mode will also be used in a multi-point serial network were all serial devices will need bi-directional
communication (Figure 6).
Terminal Server Mode - This mode of operation translates RS-232 serial data into a network-oriented terminal protocol,
such as telnet or SSH. This mode would be selected if an interactive RS-232 session at remote locations is desired
over the wireless Ethernet link.

Flow Control
Select the type of data flow control used on the RS-232 connection. The ESTeem can support Hardware flow control
(RTS/CTS control lines) or Software Flow Control (XON/XOFF). Select None if no serial flow control is necessary.
Maximum Bridge Links for Multicast Packets
This value sets the maximum number of Ethernet bridge links that the multicast packets will be sent through when used
in a multi-point system. A multi-point serial network uses multicast packets (UDP) to send the data to more than one
remote ESTeem. You want to limit the number of network bridge links that these UDP packets will be passed through
to make the network more efficient.
If you are using multiple ESTeem repeater links to send the serial data to remote locations, the value for the maximum
bridge link needs to be increased to a number greater than the longest repeater chain. For example, if you are using
four repeater (peer) links to send the serial data between two or more sites the number will need to be five (5) or greater
(Figure 4).
Destination IP Address
The ESTeem configured for the correct destination IP and port number will send and receive the serial data from another
modem. Set the destination IP address for the ESTeem where the serial data will be sent. If sending to more than one
ESTeem (Multipoint) set to a multicast address (i.e 224.0.0.1).
Note: If you are using the ESTeem Horizon in a multipoint application (multicast), you must have default
Gateway configured in the ESTeem set to the IP address of the Root Bridge modem.
Serial IP Port Number
The ESTeem configured for the correct destination IP and port number will send and receive the serial data from another
modem. Set the IP port numbers to match where the serial data will be sent. The serial data will not be sent if both the
IP address and port number is not correct.
Maximum Packet Size
This number represents the maximum size of the serial data packet in bytes. If the number of bytes of data in the serial
port buffer exceeds the maximum packet size before the timer or delimiter character is reached, the ESTeem will send
forward the serial packet. For example, if the maximum packet size is set to a value of 100, when the serial port receives
100 bytes the data will be sent through the wireless connection.
Number of Milliseconds for Packetization
This number represents the time the ESTeem will hold data in the serial data buffer before sending to the remote
ESTeem. This feature is generally used if the serial data does not have a consistent packet length or delimiter character.
For example, if the number of milliseconds is set to a value of 10 the ESTeem will monitor the incoming serial data
stream and any break in characters longer than 10 milliseconds will cause the data will be sent through the wireless
connection.
Delimiter Characters
Enabling and specifying a delimiter character will transmit the data in the serial buffer when the delimiter character is
recognized in the serial data stream. There are two unique delimiter characters that can be configured and enabled
independently.
Terminal Server Control Lines
Enabling this feature will allow the ESTeem in the Terminal Server mode to read and generate modem control lines to
the connected device.

REPEATING FEATURES
To increase the wireless network’s area of coverage
for both indoor and outdoor applications, the Horizon
utilizes a custom repeating feature that allows
increased coverage areas without the added
expense of hard cabling or adding an additional point
to point radio link.
With a conventional IEEE 802.11g or 802.11a Figure 1: Conventional Access Point Diagram
Access Point (AP) network, all of the APs have to be
interfaced to a common network either by hardwire, see Figure 1, or a separate, dedicated RF backbone. The Model
Horizon can create this RF backbone, bridge Ethernet networks connected to the wired Ethernet port and provide the
wireless canopy for 802.11 clients simultaneously.
When programmed in any of the three Access Point (AP) Repeater Modes, the Model Horizon will create a wireless
network with other Model Horizon units in radio range that are programmed in the AP Repeater Peer table during setup.
This feature adds the increased functionality of repeaters to the typical Ethernet Bridge configuration.
ESTEEM MESH NETWORK
One of the most powerful features of the AP
Repeater Mode is the ability to input multiple
communication routes and designate the priority for
each of these routes to create a wireless Mesh
network. The ESTeem Horizon will automatically
change communication routes in the network if a
route has failed. The new route will be based upon
the priority level set during configuration. This
wireless Meshing technology allows the RF network
to “self-heal” if any of the communication paths fail.
The routing priority is manually set during the
configuration of the Horizon.
A manual path
configuration is far superior to standard “selfdiscovery” networks, because you have direct control
over the best RF paths and can easily identify any
failed routes for easy troubleshooting. For example, Figure 2: Small Mesh Network Diagram
Figure 2 shows a typical wireless Ethernet system
used in the Water/Waste Water Industry. The
problem with a standard “self-discovery” Mesh network is the selection of routes. Notice that the communication
between the Water Plant (Site A) and Pump Site D has a marginal link, but it is the most direct route between the
Ethernet devices.
This scenario poses the question, which path will the network select? The ESTeem Mesh Network takes out the
guessing games by allowing the user to select and prioritize all communication routes in the system. In our example
we would want the primary link to go through Tank B (Repeater) and use the direct link only if this primary link fails. The
following sections will show how this completed.
Configuration
The configuration of the repeater paths is completed during setup of the Access Point modes. All three Access Point
modes support repeating and Meshing features. The Mesh network configuration using the ESTeem Network
Configuration (ENC) Utility is shown in detail in Chapter 3 of this User’s Manual.

an example repeater peer table from the setup menus. For an Horizon to communicate with another Horizon, select
Yes must at Enable Repeater Capability. Next, the Wireless LAN (WLAN) MAC address of each Model Horizon that
will have direct communications must be added to the Repeater Peer List. Finally, enabling the link allows the
corresponding Horizon to be included in the communication routing. Mobile clients do not require input in the repeater
peer table. If multiple Mesh routes are configured, you will also need to set the values for Priority and Path Costs
(explained in Spanning Tree below). For multiple examples of repeater configurations, please refer to Chapter 3 of this
user’s manual.

RAPID SPANNING TREE PROTOCOL (RSTP)
The ESTeem Model Horizon uses standard Ethernet Rapid Spanning Tree Protocol (RSTP) to determine the radio
routing structure of the wireless network. The primary purpose of RSTP is to make sure that “network loops” are not
created. A network loop is having two communication paths to the same destination where the remote device would
receive the same data multiple times. If there were no way to control the data flow, this data would be constantly passed
around this loop causing a “packet storm” that would shut down the entire network. The Spanning Tree Protocol will
block all these redundant links.
The RSTP operation begins by determining which Ethernet device on the network will be the Root Bridge. All Ethernet
networks have a Root Bridge that is selected by the lowest MAC address. All path costs are evaluated against this Root
Bridge device to determine routing and which paths will be blocked. On a wired Ethernet network, the location of the
Root Bridge is not really important, but in a wireless network selection of the Root Bridge is critical to the wireless
network routing. Let’s use one of the Example network diagrams from Chapter 3 to continue the discussion (Figure 4).

REPEATING FEATURES
STP Phases
The following sections describe the process of the STP in the ESTeem Model Horizon as how it would happen in the
above example.
Learning Phase - Once properly configured, each Model Horizon will begin to search out the other Model Horizon units
in radio range that are programmed in the AP Repeater Peer table. All Model Horizon’s will calculate their routes to
every Model Horizon in the network based upon the lowest “path length” to the Root Bridge. Path length is the total
number of wireless links (repeater peer links) to transmit a packet through the wireless network to the Root Bridge.
Note: The Root Bridge in a network should be the Model Horizon where the majority of the data flow is
processed. In every wireless network of two or more radios, the Root Bridge should be user defined. If not defined, the
Horizon with the lowest MAC address will be designated as the Root Bridge.
In Figure 4, the Plant network (Example 1) is the most logical location for the Root Bridge based upon the amount of
data flow. Setting this site as the root bridge is discussed below in Root Bridge.
Blocking and Forwarding Phase – To ensure you do not have a network loop situation due to redundant paths in your
wireless network, the Model Horizon will recognize and disable (block) one or more redundant links and provide back
up links should the primary link fail. This establishes a wireless mesh network with a series of forwarding links, based
upon the shortest path length to the Root Bridge.
For example, looking at Figure 4, the Remote Building has two routes to the Root Bridge (Plant Network – Example #1);
directly to the site and through the repeater. The direct link between the two sites is the shortest route (lowest Path
Length) and will be selected as the primary route unless overridden by manually changing the Path Length in the
configuration.
Path Length
If more than one communication path to the Root Bridge is found, the Horizon must determine which route to take based
upon the lowest Path Length. The default path length to all links in the Horizon network is 1. If the Path Lengths are
equal then the lowest MAC address will determine the priority route. In the ESTeem Mesh Network we want to directly
control all data flow so do not want the routes to be automatically determined.
Looking again at our Example in Figure 4, if we made no changes to the default path length of 1 (note values in Figure
3) the lowest path cost would be direct from the Remote Building to the Root Bridge (Plant Network).
Link Description
Direct from Remote Building
Remote Build to Root Bridge Through
Repeater
Total Path Length
2 (Length 1 to repeater + Length 1 to Master = 2)
To configure the Horizon to select the repeater as the primary radio path, set the path length value for the direct link
greater than 2 (such as a value of 3) to make this the primary radio path. The lowest path length will identify the highest
priority. The Model Horizon will use this routing, but also switch to direct communication if the repeater were to
disappear.
Root Bridge
In any Access Point Repeater network consisting of more than two sites, one Model Horizon should be designated as
the Root Bridge. Only one Model Horizon can be designated as the Root Bridge in a given network and should be
located where the majority of the Ethernet data flow is processed. This site may be the Master location in a SCADA
network or could be configured at a repeater site. Selection is important because all Model Horizon’s NOT configured
as the Root Bridge will choose routing based upon the Path Length to the Root Bridge. If you have any question as to
Revised: 19 Jan 16
7-4
EST P/N AA107-Horizon
CHAPTER 7
REPEATING FEATURES
which site in your AP Repeater application should be the Root Bridge, contact ESTeem Customer Support at 509-7359092 or e-mail your application to support@esteem.com.
The Root Bridge will be selected in one of two ways: the Root Bridge can be manually set (recommended) during the
configuration of the Repeater Peer table (Figure 3) or the Root Bridge designation will default to the lowest MAC address
of all the Model Horizon’s in the network. The manual Root Bridge configuration is located in the “Advanced Settings”
section.
Redundant Backup
The ESTeem Model Horizon configured in Access Point
Repeater mode will automatically function as a redundant
backup if two Model Horizon’s are installed at the same
location (Figure 7). If two Model Horizon’s are connected to
the same switch, one of the Model Horizon’s will be Blocked
when the Spanning Tree Protocol is completed. The network
will continue to use this route until any problem with the
original Model Horizon is detected and the second Model
Horizon will begin operation at that site.
Redundant Master Configuration
The configuration in Figure 7 will also provide a redundant
backup for the Master Site (Root Bridge). Configure both
Model Horizon’s as Root Bridges (see above) giving the
primary Root Bridge a value of 1 and the secondary Root
Bridge a value of 2.

ANTENNA DIVERSITY
The dual diversity antenna configuration on the ESTeem Model 216An allows the radio to operate more efficiently in
areas with high reflections (such as indoors or in a city) without direct line of sight (LOS) between the antennas. One
of the most difficult conditions to control in a radio system is the effect of a destructive reflected radio signal called
mutipathing. Multipathing occurs when waves emitted by the transmitter travel along a different path and interfere
destructively with waves traveling on a direct line-of-site path. The phenomenon occurs because waves traveling along
different paths may be completely out of phase when they reach the antenna, thereby canceling each other out. The
dual diversity antenna configuration places a physical distance between the antennas where one reflected signal will be
out of phase, but the second will be not. The ESTeem Model 216An will sample both antennas and select the best
receive signal.

216An POLE MOUNT GROUNDING PROCEEDURES
Mounting the 216An series radio modem outdoors requires proper grounding procedures to prevent damage to both
the radio hardware and the connected Ethernet and Serial peripherals. The case on the 216An series wireless modem
is electrically conductive, but the AA195 Pole Mount kit provides isolation from the connected structure. To bring the
216An case to a ground potential with Earth ground and eliminate any static buildup on the case itself, the shield on the
Ethernet cable is used to provide the ground connection.
Outdoor Ethernet Cable
A critical component of this grounding protection system is the ESTeem AA09.1 outdoor, shielded CAT-5E Ethernet
cable. This cable provides three, necessary elements; Ethernet data, DC Power over Ethernet (PoE) applications, and
a ground from the 216An case to the AA166 surge protector. The Ethernet cable is outdoor rated and protected from
UV breakdown.
Installation
The following diagram outlines all the critical components and connections in the 216An series system. The Earth

blockage. Typically, 20% Fresnel Zone blockage introduces little signal loss to the link. Beyond 40% blockage, signal
loss will become significant. This calculation is based on a flat earth. It does not take into account the curvature of the
earth. It is recommended for RF path links greater than 7 miles to have a microwave path analysis done that takes the

RF COMMUNICATIONS DATA RATE
The RF data rate of the Horizon can be programmed for operation at multiple data rates. The RF data rate can be set for a fixed
rate or a specific range that is dynamically scaled by the Horizon from monitoring the received signal quality. Dynamic scaling
means that the Horizon will operate at the highest RF data rate that is programmed into unit. If the received data quality drops
below the required minimums for reliable communications, the Horizon will reduce the data rate to the next lowest step to increase
signal quality. Conversely if the signal quality increases above the minimums the Horizon will increase the RF data rate the next
highest level.
The ESTeem Horizon is set at the
factory to operate at maximized
scaling speed data rates and should
not need adjustment. The RF Data
Rate is programmed in the Horizon
through the Advanced
Menu>Wireless LAN
Settings>Wlan0 Device and the
value for wlan0_OPRATES:. In the
example shown in Figure 3 the RF
Date Rate is programmed to dynamic
scale all data rates to 54 Mbps
(recommend factory default setting).
To set the values for the data rate,
check the box next to the listed data
rate to enable this rate for operation.

SECURITY
OVERVIEW
The security for the ESTeem Horizon, like all network security, must be multi-layered. One level of security is never enough to
make sure that data does not end up in the wrong hands. Please review the following security levels and decide what is the most
appropriate for your network.
AES-CCMP (802.11i and WPA-2)
AES-CCMP (Advanced Encryption Standard-Counter Mode CBC-MAC Protocol) is the encryption algorithm used in the IEEE
802.11i and WPA-2 security protocols. This national encryption standard uses a 128 bit-AES block cipher and CCMP technique to
ensure the highest level of security and integrity available on a wireless network. AES-CCMP incorporates two sophisticated
cryptographic techniques (counter mode and CBC-MAC) and adapts them to Ethernet frames to provide a robust security protocol
between the mobile client and the access point. AES itself is a very strong cipher, but counter mode makes it difficult for an
eavesdropper to spot patterns, and the CBC-MAC message integrity method ensures that messages have not been tampered with.
The ESTeem Horizon is compatible as either an Access Point or client in either WPA2 or IEEE 802.11i security systems.
Wi-Fi Protected Access 2 with Preshared Key (WPA2 PSK)
WPA2 PSK uses a common passphrase (preshared key) between the Access Point (AP) and the client to begin a secure communication
session. This passphrase must be entered exactly the same in both the Access Point and the client. This passphrase is used to
authenticate communication session between the AP and client to begin the secure wireless networking session.
Wi-Fi Protected Access 2 with Enterprise Server (WPA Enterprise)
Like WPA2 PSK, WPA2 Enterprise verifies the authenticity of the Access Point and client, but uses an 802.1x backend
authentication server handling the authentication decision. The most commonly type of authentication server is a RADIUS server.
The ESTeem Horizon can be configured to operate with an established RADIUS server on the network.
WPA
Wi-Fi Protected Access with Preshared Key (WPA PSK)
WPA, which uses 802.1x, was introduced in 2003 to improve on the authentication and encryption features of WEP. All
authentication is handled within this access point device. WPA has two significant advantages over WEP:
1. An encryption key differing in every packet. The TKIP (Temporal Key Integrity Protocol) mechanism shares a starting key
between devices. Each device then changes their encryption key for every packet. It is extremely difficult for hackers to read
messages even if they have intercepted the data.
2. Certificate Authentication (CA) can be used, blocking a hacker posing as a valid user.
Wi-Fi Protected Access with Enterprise Server (WPA Enterprise)
Like WPA PSK, WPA Enterprise verifies the authenticity of the Access Point and client, but uses an 802.1x backend authentication
server handling the authentication decision. The most commonly type of authentication server is a RADIUS server. The ESTeem
Horizon can be configured to operate with an established RADIUS server on the network.
WPA is server/client relationship from a software driver on a computer’s wireless LAN (WLAN) card to an Access Point. The
scope of WPA is limited in use to this configuration only. The ESTeem Horizon can support WPA Enterprise and PSK as an Access
Point, but the level of security on the Bridging layer is configured separately.

APPENDIX D
SECURITY
128-BIT WEP
The 128 WEP uses a particular algorithm called RC4 encryption to encode and decode traffic that is based on a 104-bit encryption
key and a 24-bit Initialization Vector (IV). RC4 starts with a relatively short encryption key (104 bits) that is expanded into a nearly
infinite stream of keys to accompany the stream of packets.
The basic concept of RC4 is good, but the way it’s implemented in WEP leaves it open to compromise. The researchers that test
the integrity of the system usually focus on one piece of the implementation, the Initialization Vector (IV).
The IV (24 bits) is the algorithm component that’s supposed to keep expanded keys from repeating. From the researcher’s point of
view, a high-volume access point is mathematically guaranteed to reuse the same key stream at least once a day. When this happens,
it’s called an IV collision this becomes a soft spot to enter the system.
The researchers aren’t saying that it’s easy to break into the system, or that it’s being done on a regular basis, only that it is possible
and administrators should consider ways to reduce the possibility
ACCESS CONTROL LIST (ACL)
The ACL is one of the simplest yet most secure methods of network security. The ACL is a configurable MAC filter in the Model
192E that can be set to allow specific MAC address on the wireless network by individual address or address ranges. The same
filter can also be set to reject individual MAC addresses or address ranges.
The MAC address is a unique, 6 hexadecimal field address assigned at the manufacturer that can not be changed. The MAC address
is traceable through the IEEE governing body to the manufacturer and is the “fingerprint” for all Ethernet devices.
Using a combination of both the WPA or 128-Bit WEP encryption and the ACL filter provide the ESTeem an extremely secure
wireless networking layer.
DISABLING BROADCAST PROBES AND HIDING SSID
A simple but very effective way of securing a network is to make the network difficult to find. By disabling broadcast probes and
hiding the Service Set Identification (SSID), wireless and network “sniffers” will not be able to find your ESTeem Horizon network.
To gain access to the wireless network, you would be required to have the SSID and all security loaded in the WLAN card software
prior to entering the network.
PROPRIETARY BRIDGE COMMUNICATION
Although the ESTeem Horizon is compatible with the open communication standards IEEE 802.11g and 802.11b, the repeater
communication between the units is a proprietary communication link. No other manufacturer of wireless hardware can access the
ESTeem repeater network when bridging between Ethernet networks. This proprietary communication layer, in combination with
the other security settings, allows you as the user to reject wireless clients into the network if so desired. When used in conjunction
with the Access Control List the 802.11g and 802.11b client access can be removed.
The security level of the bridge communication link is configurable for 64-Bit WEP, 128-Bit WEP or TKIP and is completely
independent of the client access level or any other communication link level. For example, an ESTeem Horizon can be configured
for WPA Enterprise for client level access, communicate to another ESTeem Horizon using a TKIP bridge link and also
communicate 128-Bit WEP to our older ESTeem Model 192E radio modems all running simultaneously.

SECURITY
MASQUERADE MODES
When the ESTeem Horizon is configured in either the Access Point Masquerade or the Client Masquerade modes, the wireless
modem functions as a network firewall. If access to the wired network is the greatest concern, place the ESTeem in the Masquerade
mode and the wireless network will be completely isolated from the wired Ethernet network.
INCREASING NETWORK SECURITY
The following are a few suggestions to help improve the overall security of your wireless network:
1.
Enable the security. If you research all of the articles regarding hackers, they have gotten into the user’s network due to the
security not being enabled.
2.
Set the ACL filter to include only those MAC address of the wireless Ethernet device being used on the network.
3.
Make sure the keys are not reused in your company, since reuse increases the statistical likelihood that someone can figure the
key out and change the default password on your access point or wireless router
4.
As a network administrator, you should periodically survey your company using a tool like NetStumbler to see if any "rogue"
access points pop up within your company without authorization. All of your hard work to "harden" your wireless network
could be wasted if a rogue AP was plugged into your network behind the firewall.
5.
Many access points allow you to control access based on the MAC address of the NIC attempting to associate with it. If the
MAC address of your NIC isn't in the table of the access point, you won't associate with it. And while it's true that there are
ways of spoofing a MAC address that's been sniffed out of the air, it takes an additional level of sophistication to spoof a MAC
address. The downside of deploying MAC address tables is that if you have a lot of access points, maintaining the tables in each
access point could be time consuming. Some higher-end, enterprise-level access points have mechanisms for updating these
tables across multiple access points of the same brand.
6.
Consider using an additional level of authentication, such as Remote Access Dailin User Service (RADIUS), before you permit
an association with your access points through WPA and WPA2 Enterprise.
7.
If you're deploying a wireless router, think about assigning static IP addresses for your wireless NICs and turn off Dynamic
Host Configuration Protocol (DHCP). If you're using a wireless router and have decided to turn off DHCP, also consider
changing the IP subnet. Many wireless routers default to the 192.168.1.0 network and use 192.168.1.1 as the default router.
8.
Only purchase Access Points that have flashable firmware. There are a number of security enhancements that are being
developed, and you want to be sure that you can upgrade your access point.
9.
A simple security technique used by the military is to have the administrator periodically change the key for the system i.e.
weekly, monthly, etc.

The average signal strength required to maintain a specific data rate will vary by ESTeem Horizon model and bandwidth.
To review the required signal level and its effect from distance and hardware selected, please use the ESTeem RF
Design program available from our web site (www.esteem.com). Please note that the data rates can be greatly affected
by overall activity on the radio channel and the total background noise. These values should be used as a guide, but
testing after installation is required.
LONG RANGE POINT TO POINT APPLICATIONS
The factory configuration on the Horizon is optimized for distances up to 10 miles. If your application has an RF link
with a range greater than 10 miles, you will need to set the maximum range value on both ESTeem Horizon’s on this

TROUBLESHOOTING TIPS
General (Applicable to All Modes of Operation)
Where do I find the latest firmware version number? – We have the latest version number of the Horizon firmware listed
on the ESTeem Web site (www.esteem.com) under the Horizon product page.
How and when do I update the Horizon firmware? - You should only update the Horizon firmware if you are having a
specific problem and it is recommended that you do so by ESTeem Customer Support personnel. All the update
instructions and files are located on the ESTeem FTP site at the following address:
ftp://www.esteem.com/Horizon
Do all firmware versions have to be the same to communicate between the Horizon? – It is not necessary for all the
firmware versions to be the same revision to communication, but the later version may have added features that the
other versions will not recognize.
What characters are valid for WEP Key entry? - Only the Hexadecimal characters 0-9 and A-F are valid for key entry.
What ESTeem Utility version is required to program the Horizon? – The ESTeem Utility program is not required to
program the Horizon. The Horizon can be programmed using any Terminal Emulation program (such as Windows
HyperTerminal) and any web browser program.
What is the speed and duplex configuration on the Horizon – The Horizon is an auto-negotiation full/half-duplex 10/100
Base-T interface. Ether a cross-over or patch cable is supported.
Access Point Mode
Wireless LAN cards are not connecting – Verify that the wireless LAN cards are set to Infrastructure Mode, have a
matching SSID (or ESSIS) set the same as the Horizon and that all encryption codes are the same.
My Wireless LAN card shows a solid connection, but I can not pass any data – Verify the encryption and the ACL setting
on the Horizon match the wireless LAN card.
Access Point Repeater Mode
How long does it take to re-establish the Wireless Ethernet Network? - If a communication link is lost and the Wireless
Network needs to re-establish the repeater routes, the time can take up to 10 seconds.
Should the AP Repeater Mode be used on mobile equipment? - The AP Repeater mode should be used on equipment
that will not change the Repeater Route as it moves. For example, if a mobile device such as a crane can communicate
directly to another ESTeem and will not loose the link in its travel, the AP Repeater Mode could be used. If the device
requires two ESTeem Horizon’s (Base and Repeater) to maintain communication across its complete travel, the Station
Modes should be used on the mobile device. The problem will be in the time that the mobile ESTeem will take to transfer
between the two sites. In Access Point Repeater mode the transfer can take up to 30 seconds, while the EtherStation
mode will transfer without a packet loss.
Does WEP have to be used? – The WEP does not have to be enabled for the modems to communicate, but all modems
must be configured the same way.
Correct configuration, but cannot establish communications. – In addition to the network configuration, all Horizon
modems configured in the AP mode must share the same SSID and be on the same frequency channel. The most
likely cause of the error is the WLAN MAC address is not configured in both Horizon’s repeater tables. If only one side
is configured, everything will appear to be correct but no communication will function.

EtherStation
How do I access the Horizon web page in EtherStation Mode? The Horizon does not have an active web browser when
configured in EtherStation mode. You must access the ESTeem with the ESTeem Discovery Program or through the
RS-232 port after configuration in this mode. To monitor the link status, you can use the EtherStation Status program.
What IP address do I configure the ESTeem in EtherStation mode? – The Horizon will not have an IP address in
EtherStation mode.
I can not link my device into the wireless network – Verify that the MAC address of the device is exactly the same as
configured in the Horizon. The MAC address must have colons between the values.
Can I connect my Horizon in EtherStation mode to a HUB or Ethernet Switch? – No. The modem must be connected
directly to the Ethernet device for which it is programmed. In EtherStation mode the Horizon can only service ONE
Ethernet device.
