2.7. Antenna Options
Antennas are available for L-5500 radio modems installations from Logic Data Systems.
2.7.1. Primary Cellular Antenna
The L-5500 product requires a multi-band cellular antenna for operation in the 800 MHz
band, the 1900 MHz band, and the 2100 MHz band. The primary antenna connection on the
L-5500 unit is an SMA female connector; therefore you must purchase an antenna with an
SMA male connector. Do not select an SMA antenna with “reverse polarity” or RP-Male.
Mounting options and cable lengths are the user’s choice and application specific.
Caution: To comply with FCC approval for this device, do not use a cellular antenna with a
gain greater than 5 dBi in the cellular (800MHz) band, or 4 dBi in the 1900MHz band.
2.7.2. RX Diversity Cellular Antenna
The L-5500 radio modem RX Diversity antenna has the same requirements as the primary
antenna with the exception of the connection. The RX Diversity antenna connection on the
L-5500 product is an SMA female connector; therefore an antenna with an SMA Male
connection is required. Mounting options and cable lengths are the user’s choice and
application specific. For best performance, separation between the Primary and Diversity
antenna should be at least 5/8 wavelength (=8 inches or 20 cm for 915 MHz).
Caution: To comply with FCC approval for this device, do not use a cellular antenna with a
gain greater than 5 dBi in the cellular (800MHz) band, or 4 dBi in the 1900MHz band.
2.7.3. GPS Antenna
The L-5500 radio modem’s GPS connector requires an external 3.3V GPS antenna. The GPS
antenna connection on the L-5500 product is a female SMA connector; therefore an antenna
with an SMA male connector is required. For best coverage, use an active antenna with a
gain >25dB. Mounting options and cable lengths are user’s choice and application specific.
2.7.4. WiFi Antenna
The WiFi antenna connection on the L-5500 product is an RP-SMA jack; therefore an
antenna with an RP-SMA plug is required. Mounting options and cable lengths are user’s
choice and application specific.
2.7.5. Antenna Spacing
Referring to Figure 4 for illustration, the L-5500 radio modem commonly uses four
separate antennas:

Page 8
“T” - Main transceiver - Constraints are the limit of 20 cm and omni-directional
factors
“R” - Auxiliary receiver – Constraints are the receiver spacing of at least 5/8 λ
(wavelength) from transceiver antenna and omni-directional requirements
“G” - Global Positioning System (GPS) - Constraints are TX spacing of at least
60cm/23.62 inch from all transmitting antennas and a clear view of the sky.
“W” – WiFi antenna - Constraints are TX spacing of at least 8 inches or 20 cm from
all transmitting antennas
Note: For units utilizing diversity cellular antennas, best overall operation is achieved
utilizing antennas with equal gains.
WARNING: As per FCC rules, all L-5500 transmitting antennas (T & W) should be at a
minimum of eight (8) inches (approximately 20 centimeters) from all persons.
Figure 4 - Antenna Spacing (T: primary antenna, R: diversity antenna, W: WiFi antenna, G:
GPS antenna)
For installation of ground-plane dependent antennas (main cellular and WiFi antennas), the
center of the metal surface used for mounting is preferable for best omni-directional
pattern. For ground-plane independent antennas (diversity and GPS antennas), installation
may be close to the edges of the surface.
For vehicular installations Logic Data Systems recommends the following antenna positions:
Most preferred for all antennas: centerline of roof. For transmitter antenna, it is the
ONLY acceptable position.

Page 9
Less preferred for receiver antenna: trunk lid, providing distance to transmitting
antenna is respected whether lid is opened or closed.
Much less preferred, but permissible for receiver antenna: left or right rear fenders,
just in back of rear window
Least preferred, but permissible for receiver antenna: left or right front fenders,
ahead of windshield

3. Networking Basics
3.1. General Networking Definitions
The L-5500 cellular modem 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 L-5500 environment.
Term Definition
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 L-5500 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 L-5500 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.
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.
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.
Packet Data Packet Data is used by 3G cellular standards. On a packet data network,
users share a channel and the connection is always on.
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

Page 11
By default the L-5500 radio modem uses the 192.168.1.x address range.
Provisioning The process of activating a unit for the first time on a cellular carrier’s
network. You must have a service contract in place with the carrier prior to
provisioning your device.
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 an L-5500 network must be on the same subnet as
the L-5500 radio modems.
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.
