CHAPTER 4
CONFIGURATION SETUP
PROGRAMMING EXAMPLE
Listed in this chapter we will give you an overview programming the most common use of the Model 195Eg, as a wireless
Access Point Bridge to a hardwired LAN with Repeater Enabled. In these examples we will program the Model 195Eg from the
unit’s Web Configuration Manager’s Setup.
Access Point Bridge with Repeater Enabled
1. Review the Access Point Bridge diagram. See Figure 1.
Figure 1: Access Point Bridge Diagram
2. Refer to the top left corner of Figure 1 to the Model 195Eg that is interfaced to the Hub or Switch. This unit is configured as
a wireless Access Point Bridge to the hardwired LAN. In this example the Model 195Eg will have to be programmed in the
Access Point Bridge Mode described in Chapter 1. This Model 195Eg will serve as the base node for 802.11g clients.
3. If you have not defined the IP address of the Model 195Eg then follow the instructions in Chapter 2.
4. Access the ESTeem Web page using your computer’s Web Browser as per instructions in Chapter 3 under Logging On To
the ESTeem Web Configuration Manager.

9. Select if you will be using security for your wireless network. Enter the SSID for you 802.11g network. The SSID is the
unique identification for your wireless network and all 802.11g devices that share a wireless network MUST have the same
SSID code. This identification code is case sensitive and must NOT contain spaces. Reference Figure 6.
Figure 6: SSID Setup Screen
10. Select the encryption level for the wireless network. If you would like to hide the SSID from broadcasting from the Access
Point select Yes. If Yes is selected the Model 195Eg will not send out periodic SSID radio beacons that can be identified
with 802.11b network scanning software. The users of the network will have to know the SSID to enter the network and
security is increased, but if you want the SSID to be broadcasted to the network for easy identification then select No.

REPEATING FEATURES
The Repeating Feature in the Model 195Eg is used to
increase the wireless network area of coverage for both
indoor and outdoor applications without the cost of
hardwiring the Access Points to a common LAN. This
custom feature is unique to the Model 195Eg because
conventional 802.11b/g Access Points have to be
interfaced to a common network either by hardwire, see
Figure 1, or a dedicated point to point RF backbone.
Figure 1: Conventional Access Point Diagram
When programmed in the Access Point (AP) Repeater Mode, the Model 195Eg will automatically create a wireless network with
other Model 195Eg units in radio range that are programmed in AP Repeater mode and setup with matching configurations.
This feature adds the increased functionality of repeaters to the typical Ethernet Bridge configuration.
AutoRouting
One of the most powerful features of the Repeater
Feature mode is the Model 195Eg’s ability to
automatically calculate all possible
communication routes in the network. The
AutoRoute feature will automatically establish
wireless Ethernet communication paths to each
Model 195Eg that has a matching setup
configuration. This automatic routing greatly
simplifies network configuration and also creates
a “self healing” network by sending data on an
alternate route, if available, upon failure of the
primary path.
AutoRouting Process
Figure 2: AP Repeater Diagram
Listening Phase. Once a modem is configured
for Access Point Repeater mode and reset, the
Model 195Eg will begin to search out all modems that have a matching configuration setup (SSID, Frequency Channel, AP
Repeater Mode = ON and Security Codes). The first step in the routing process is sending out and listening for “repeater
beacons”. A repeater beacon is a special radio packet that is sent from the Model 195Eg that contains the unit’s MAC address.
When a repeater beacon is received by another Model 195Eg, the MAC address of the originating modem is added to its own
repeater beacons. A route between two Model 195Eg units can be established when they receive a repeater beacon that
contains their own address.
For example let’s look at Figure 2 and the repeater beacons and the route created from Pump Site C and Tank Site B(Repeater).
Pump Site C sends a repeater beacon containing its MAC address over the radio network. The only site that receives this
repeater beacon is Tank Site B (Note – there is no Line-of-sight (LOS) between from Pump Site C to the other sites in the
network). When Tank Site B receives the repeater beacon it adds the MAC address from Pump Site C to its own repeater
beacon and sends it out. This new repeater beacon from Tank Site B (Now containing Pump Site C’s MAC address) is received
at Pump Site C and a route is established. Pump Site C then adds the MAC address for Tank Site B in its repeater beacon, which
is eventually received by Tank Site B.
Repeater beacons will continually be sent from a Model 195Eg every 2 seconds as long as it is configured in AP Repeater mode.
This will allow the Model 195Eg to recognize new sites into the network and any changes to the radio paths. These continued
updates in the repeater beacons give the AP Repeater network the “self-healing” characteristic.

CHAPTER 5
REPEATING FEATURES
Learning Phase. After an approximate 10-second period after no further additions to the Mac addresses in the repeater
beacons, the Model 195Eg goes into the learning phase. In this phase all Model 195Eg units calculate their routes to the other
Model 195Eg units in the network using the lowest “path cost”, meaning shortest number of hops, back to the Root Bridge.
Note: The Root Bridge in a network should be the Model 195Eg where the majority of the data flow is processed. In Figure 2,
the Root Bridge will be the Water Plant that is transmitting and receiving data from all three remote sites. The user can program
the Root Bridge manually. If the user does not define the Root Bridge, and if there are multiple candidates for the Route Bridge,
Model 195Eg units in the network will pick the unit with the lowest MAC address. See the following section on Root Bridge for
further details.
Blocking and Forwarding Phase. This last phase in the auto-routing process will eliminate any Ethernet data “loops” that can
double the information received at any remote site. For example, looking at Figure 2, Pump Site D has two routes to the Root
Bridge (Water Plant – Site A). The first Route is direct from the Water Plant and the second Route is via the Tank Site B
(Repeater site). In this example the direct link between the two sites is the shortest route (lowest Path Cost) and will be selected
as the primary route or Forward route. The second route (one with the higher Path Cost) that uses the repeater will be
“Blocked”. All routes to the Root Bridge will be evaluated for the site and be Forwarded or Blocked. The average time to
complete all routing phases in a network is approximately 30 seconds.
Root Bridge
For any Access Point Repeater application that has more than two sites, the user needs to set one of the Model 195Eg’s as the
Root Bridge. The Root Bridge should be the Model 195Eg 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
the Model 195Eg’s that are “NOT” configured as the Root Bridge will select their routing based upon where the Root Bridge is
defined in the network.
The Root Bridge will be selected in one of two ways:
1. Manually by the users. The Root Bridge can be manually set (recommended) during the configuration at AP Repeater
mode. Reference Chapter 4 – AP Repeater Configuration.
2. Automatically by the Model 195Eg. The Model 195Eg units will automatically configure the Root Bridge by selecting the
lowest MAC address of all the Model 195Eg units in the network. This is usually not recommended in large networks,
because adding a new site to the network could adversely change the entire site’s routing scheme.
If you have any question establishing Route Bridges in your network, contact ESTeem Customer Support at 509-735-9092 or email your application to support@esteem.com .

REPEATING FEATURES
Using the Access Control List (ACL) In Network Design
As mentioned above, the shortest route to the Root Bridge may not be the
best radio path. As seen in Figure 2 the radio path from Pump Site D to the
Water Plant – Site A has a marginal link. Although the shortest route from
Pump Site D to the Water Plant is direct, the best radio path is using the
repeater site at Tank Site B. To force the radio path through the repeater is
as simple as setting the ACL in the Pump Site D Model 195Eg to Deny the
Mac address of the Water Plant. This will force all communications from
Pump Site D to the Water Plant via Tank Site B.

FRESNEL ZONE
The Fresnel zone shows the ellipsoid spread of the radio waves around the visual line-of-sight after they leave the antenna (see
figure above). This area must be clear of obstructions or the signal strength will be reduced due to signal 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 curvature of the earth and the topography of
the terrain into account.
