Manual
3. Networking basics
3.1 General Networking Definitions
The Sentry 4G router is based on Ethernet connectivity and follows general IP networking
guidelines and terminology. Below are definitions of some basic network terminology as they
pertain to the Sentry 4G environment.
Term
Definition
BTS
Base Transceiver Station, fixed equipment that incorporates all radio-
intelligence functions controlling the 802.16-2005 link with one or more Sentry
4G routers.
CINR
Carrier to Interference-plus-Noise Ratio, expressed in decibels (dBs), is a
measurement of signal effectiveness. It provides information on how strong the
desired signal is compared to the unwanted energy (interference plus noise).
DNS
Domain Name System: operates like a phone book to translate domain names
(i.e., google.com) to IP addresses (70.212.19.1).
The Sentry 4G unit functions as the DNS Server in the network.
DHCP
Dynamic Host Configuration Protocol: the DHCP server assigns IP addresses,
gateway and subnet masks to all clients on the network.
The Sentry 4G unit functions as a DHCP Server.
Dynamic/Static IP
A device with Dynamic IP selected may have a different IP address every time
it connects to the network. A device with a Static IP will always connect with
the same IP address.
EAP-TTLS
(Extensible
Authentication
Protocol-Tunneled
Transport Layer
Security)
A universal authentication framework frequently used in wireless networks and
Point-to-Point connections. EAP-TTLS is an EAP method that encapsulates a
TLS session, consisting of a handshake phase and a data phase. During the
handshake phase, the server is authenticated to the client using standard TLS
procedures, and keying material is generated in order to create a
cryptographically secure tunnel for information exchange in the subsequent
data phase. During the data phase, the client is authenticated to the server
using an arbitrary authentication mechanism encapsulated within the secure
tunnel.
Gateway
A (node) device enabling data transfer between different networks (i.e., from a
private LAN to a public WAN).
LAN
Local Area Network. A private network.
MIMO
Multiple Input Multiple Output. MIMO algorithms send information out over two
or more antennas; the information is received via multiple antennas as well.
This use of multiple antennas at both the transmitter and receiver provides a
significant capacity gain over conventional single antenna systems and/or
a more reliable communication.
NAT
Network Address Translation: A technology that allows hosts on the LAN with
private IP addresses to communicate with public IP addresses on the WAN.
This is an essential function of a network router.
OFDM
Orthogonal Frequency Division Multiplexing. 802.16-2005 being a wide area
network is very sensitive to interference and multi-path fading. OFDM
addresses these problems by partitioning the data stream into multiple
narrowband transmissions in the frequency domain using subcarriers that are
orthogonal to one another (do not interfere). These subcarriers are then
reassembled for over-the-air retransmission.
OFDMA
Orthogonal Frequency Division Multiple Access. Allows OFDM to serve many
terminals. Each terminal will be assigned a subset of the subcarrier set for a
NETWORKING BASICS
001-9193-001 Version 2 Page 14 of 52 Sentry 4G TM User
Manual
given time interval.
Port
A special number present in the header of a data packet in the data transfer
process. Ports are typically used to map data to a particular process running on
a computer.
PPP
Point-to-point Protocol: creating a direct link between two nodes in network
communication.
Private IP address
Private IP addresses are addresses that will not be routed on external
networks. Any device on an internal LAN should be assigned a private IP
address to avoid contention. The suggested private address ranges are
Class A: 10.x.x.x
Class B: 172.16.x.x through 172.31.x.x
Class C: 192.168.x.x
By default the Sentry 4G unit uses the 192.168.1.x address range.
RIP
Routing Information Protocol, protocol that helps routers dynamically adapt to
changes of network connections by communicating information about which
networks each router can reach and how far away those networks are.
SOFDMA
Scalable OFDMA. With bandwidth scalability, Mobile 802.16-2005 technology
can comply with various channel assignments.
SSID
Service Set Identifier. This is a name used to identify a WiFi wireless network.
Subnet
A range of addresses assigned to a LAN.
All devices connected in a Sentry 4G network must be on the same subnet as
the Sentry 4G routers.
Subnet Mask
Binary string that separates the subnet portion of an IP address and the host
portion.
TKIP/AES
“Temporal Key Integrity Protocol” is an encryption method used by the WiFi
interface when operating in WPA mode. TKIP was designed to solve security
issues in WEP (it is considered stronger then WEP).
"Advanced Encryption Standard" is the encryption protocol used by the WiFi
interface when it operates in WPA2 mode.
WAN
Wide Area Network, a public network. The Internet is an example of a WAN.
WEP
Wired Equivalent Privacy. This is an IEEE security protocol for wireless 802.11
networks. It is an encryption method used by the WiFi interface.
WiFi
(802.11b,
802.11g)
Wireless Fidelity is an IEEE 802.11 standard for wireless LANs
802.11b is a standard for operating at 2.4 GHz frequency with data rates up
to 11 Mbps
802.11g is a standard for operating at 2.4 GHz frequency with data rates up
to 54 Mbps
WiFi Access Point
(802.11)
A Sentry 4G unit can operate in 802.11 access point mode. It can
communicate with other devices operating in 802.11 access point mode.
WiFi Client (802.11
Infrastructure
mode)
A Sentry 4G unit can operate in 802.11 Infrastructure mode. In this mode it is
a WiFi client and will try to connect to a WiFi access point.
WLAN
Wireless Local Area Network, a private network. Refers to the network covered
by the WiFi interface.

Figure 11 - IP Settings
Sentry 4G features two Ethernet ports. The ETH0 and ETH1 IP Settings pages contain the
basic configuration information required to customize your LAN with the Sentry 4G router as
the network connection point. User configuration will primarily occur on this page.
5.4.1 IP Settings
5.4.1.1 IP Configuration
Ethernet IP address: LAN IP of the Sentry 4G unit. This address is entered into a browser
on a local PC when logging into the Sentry 4G home page. To decrease the chances of
unwanted access, this value should be changed from its default prior to use.
IMPORTANT NOTE:
CONFIGURATION
001-9193-001 Version 2 Page 28 of 52 Sentry 4G TM User
Manual
Changing this value will cause you to lose connection to the Sentry 4G unit.
Enter the new address in the browser to reconnect. If you forget an address or
make a mistake entering the new value, it may be difficult to reconnect to the
device.
Ethernet Subnet Mask: The Subnet mask is used in conjunction with the Ethernet IP
address to partition the address into the network (subnet) portion and the host portion. This
value will be entered automatically by the software based on the class of IP address entered.
It is not be necessary to change the default value once the Ethernet IP is entered.
5.4.1.2 DNS Masquerade
See the definition for DNS in Network Basics in section 3.1 above.
DNS Auto: The command enables/disables the Sentry 4G DNS server. Except in special
cases, this should always be enabled.
5.4.1.3 DHCP Server Configuration
DHCP Server: (Dynamic Host Configuration Protocol) A protocol used by client devices that
are connected to the LAN port of this device to automatically obtain an IP address assigned
by this server/router. Selecting Enable will configure this device to assign IP addresses to
client devices taken from a pool specified by the values entered in DHCP start range and
DHCP end range. If DHCP is disabled, the information must be entered manually on all PCs.
DHCP Start IP Address/End IP Address: Sets the range of IP addresses assigned to the
PCs. The user can limit the number of devices allowed on the network by limiting the range of
IP addresses.
IMPORTANT NOTE:
The addresses in this range must be on the same subnet as the Ethernet IP
IMPORTANT NOTE:
The Ethernet IP should not be in the DHCP range.
DHCP Lease Time: Number that dictates the length of time a device on the LAN can hold an
IP address. In most cases, this should be set to the maximum (default value) of 86400. If
this value is set too low, it can cause network connectivity problems.
Domain Name Suffix: The DNS suffix to be assigned by the DHCP server.
Preferred DNS Server: IP address of the preferred DNS server.
Alternate DNS Server: IP address of the alternate DNS server.
5.4.1.4 Disabling DHCP server
When DHCP server is enabled, any PC with physical access to the Sentry 4G Ethernet port will
be assigned an IP address and have access to browse the Internet. This may cause security
problems. Disabling DHCP server will allow the user to control which PCs have the ability to
connect through the Sentry 4G unit. If changes are made to the network settings, be sure to
keep a record of the changes for future use.
Disabling DHCP server is performed on the LAN settings page. Under the DHCP section,
select Disable, then click Save.
IMPORTANT NOTE:
This also disables DNS Masquerading. Disabling DHCP server will remove all values
in the DHCP and DNS sections. Record all values in these fields prior to disabling in
case you are required to go back to the original configuration.
To improve security, change the Ethernet IP of the Sentry 4G unit from the default
setting.
CONFIGURATION
001-9193-001 Version 2 Page 29 of 52 Sentry 4G TM User
Manual
IMPORTANT NOTE:
If the DHCP server is disabled, and you do not have a record of the Ethernet IP,
you will not be able to login to the Sentry 4G router home page.
On the network setting page of each PC set the following
– IP address: Set a unique address on the same subnet as the Sentry 4G
– Subnet Mask: Set to the same value as the Sentry 4G Ethernet Subnet Mask field
– Default Gateway: Ethernet IP of the Sentry 4G
– Preferred DNS: Ethernet IP of the Sentry 4G
When these settings are complete, the PC will have network access.
5.4.1.5 Static IP Setup
If your network requires each PC to have a statically set LAN IP addresses, follow the
previous procedure for all PCs on the network. If the network requires a mix of static and
dynamically assigned IP addresses, assign static IPs outside the DHCP address range for PCs
that require static IP addresses and allow the Sentry 4G DHCP to assign the remaining PC IP
addresses.

Figure 12 - Sentry 4G Router WiFi Modes: Access Point (A); Client Mode (B)
In access point mode, the Sentry 4G router offers wireless tether. It forwards local WiFi
traffic to application servers over the broadband 802.16-2005 network and works in parallel
with Ethernet connection, providing for simultaneous WiFi and Ethernet connections (see
Figure 12A).
In client mode the Sentry 4G unit can automatically switch between broadband 802.16-2005
and WiFi connections providing for seamless handover when coupled with modern
applications (see Figure 12B).
5.5.1 WiFi (WLAN)Wireless Settings (Client)
The user can configure up to 20 access points.
Note: All access points must run a DHCP server.
In wireless client mode, the Sentry 4G unit will try to connect to the Access Point with the strongest
signal on the list. When the Sentry 4G unit connects to an access point, it starts a DHCP client
service. The DHCP server running on the access point must provide an IP address, netmask, and
gateway to the Sentry 4G unit. When the WiFi client is connected to a WiFi access point, the default
route is set to point to the gateway address obtained by the DHCP client.

5.6.1 Static Routes
Figure 17 - Static Routes
The Sentry 4G unit will automatically set up routing to all devices on the same subnet. In
some cases however, the Sentry 4G unit may need to communicate with a previously existing
subnet other than its own. This route cannot be automatically generated; it must be manually
entered as a static route by the user. The static route gives the Sentry 4G router its “next
hop” instructions.
Route no: A generic number assigned to the route. Multiple static routes can be assigned as
long as they have distinct route numbers.
Description: Nickname assigned to the route by the user.
IP Address: This is the destination IP address that is delivered to the Sentry 4G unit. Since
this IP address will not be on the same subnet, the Sentry 4G unit will not have a defined
route, and will not know where to send it by default. Setting up the static route will inform
the Sentry 4G unit where to send the data.
Subnet Mask: The Subnet mask is determined by the subnet of the destination address
Gateway: This is the address that the data packet will be routed to.
Note:
The device at this address must be a router that is either on the same subnet as the
Destination IP or one with its own statically setup route to the destination address. If this
is not the case, the packet data will be dropped.
CONFIGURATION
001-9193-001 Version 2 Page 37 of 52 Sentry 4G TM User
Manual
Metric: This sets the priority of the routes compared to other static routed defined. The
lower the number, the higher priority the route.
Click on “Add” when all necessary information has been entered. The route will be shown on
the bottom of the screen (under Static Routing Table). Additional routes can be added
provided they have a unique Route no, name and metric. Routes can be deleted by clicking
the Delete Entry option of the desired entry.
Note:
Routing table (found under “Routing Table” tab) shows all routes, while Static Table
(found under “Static Routing” tab) shows manually entered routes only.
5.6.2 IP Filtering
IP Filtering provides certain Internet firewall protection. The user can enter up to 20 IP filters. Each
IP filter is identified by a unique number (from 1 to 20). When IP filtering is enabled, any custom IP
filter entered by the user as well as predefined IP filters will be taken into account when processing
IP packets. See Figure 18.
An IP packet passes through the filtering logic when IP filtering is enabled:
1) An IP packet is received on one of the interface and is destined to the Sentry 4G unit
OR
2) An IP packet is sent by the Sentry 4G unit
OR
3) An IP packet is forwarded by the Sentry 4G unit.
5.6.2.1 Predefined IP Filters
Drop Remote Pings: If IP filtering is enabled, any ICMP echo request coming from the WAN
interface will not be replied to. This prevents remote hosts from detecting your IP address on the
WAN.
Drop Remote IP Fragments: If IP filtering is enabled, any fragmented IP packets coming from the
WAN interface will be dropped.
Drop Invalid Packets: If IP filtering is enabled, any invalid packet received by the unit will be
silently dropped. An invalid IP packet is one that cannot be identified.
5.6.2.2 Add Custom IP Filters
Fill in the parameters described below and click “Add…”. Your entry will appear in the Custom IP
Filters table on the bottom of the page.
Note: Criteria are for inclusion by default. Select “exclude” if your criterion is for exclusion.
Filter Number: Each IP filter is identified by a unique number from 1 to 20.

Report every: GPS can be programmed to report position after a specified time has elapsed
or the unit has moved a specified distance since its last report.
But no less than: This feature prevents a fast moving vehicle from reporting too frequently
if its “Report every ….. meters” setting is sufficiently low” by setting a minimum amount of
time, in seconds, between GPS reports.

Alarm
Input to
Sentry 4G
Active low signal. To trigger an alarm, short this signal to VIN- using
a low impedance path (100-Ohm max)
For 200ms minimum. Otherwise, leave open or connect to VIN+. This
signal can also be driven from a 5V/3.3V TTL/LVTTL or CMOS circuit.

5.9.1 I/O Configuration
The Sentry 4G I/O subsystem is configured via the Sentry 4G WEB pages. Status Monitoring is
provided via NMEA-based protocol. The Sentry 4G I/O subsystem operates according to a
manager/agent model. The PC-hosted manager sends requests to the Sentry 4G I/O agent, which
performs the required actions. The Sentry 4G agent reports alarms and indications to the PC-hosted
manager.
Figure 27 - I/O Settings-Status
The Manager IP address is configured under I/O SettingsNMEA Settings Manager IP address
(see Figure 28).
The port number is 6969 by default and can be customized under I/O SettingsNMEA Settings
Manager IP address Port.
Note: If Auto is selected for “Manager IP address”, the Sentry 4G automatically computes the
manager IP address to be Sentry 4G ETH address +1 if DHCP is disabled. If DHCP is enabled, the IP
address is the starting address offered by the DHCP server.
The unit IP address is the source IP address (displayed in the alarm messages received by the
Manager). The user can configure this to be the WAN Sentry 4G IP address or the LAN (Ethernet)
Sentry 4G IP address. If auto is selected, the source IP address is automatically computed to be
Sentry 4G ETH address +1 if DHCP is disabled. If DHCP is enabled, the IP address is the starting
address offered by the DHCP server.
The user can enable and disable digital alarms by selecting appropriate “enabled” and “disabled”
radio buttons under I/O Settings (Error! Reference source not found. 28).
The alarm messages can be configured for each diagnostic value under I/O SettingsLabels (see
29).
