2.2.4. WLAN Terminal Antenna Kit
For specifications, see “WLAN Terminal Antenna Specifications” on page A–3.
The following materials are included in the installation kit:
• Antenna, 6 dBi radome omni, 12.25"
• L mount bracket
2.3. Installing the Smart-Reach Vehicle Station and
Antenna
The Smart-Reach vehicle station is clearly labelled and is meant to be installed on
the vehicle. The vehicle station is configured before the product is shipped to the
customer. To change the configuration, see Chapter 3, “Network Configuration”.
The WLAN mobile antenna is installed on the roof of the vehicle. The antenna is
provided with a coaxial cable to connect to the Smart-Reach. For optimum signal
reception, use the antenna cable provided with the Smart-Reach. Longer cables
can be obtained; however, a longer antenna cable results in a weaker signal
strength, which means a shorter wireless range, similar to voltage losses which
occur on long transmission lines.
2.3.1. Step 1: Choosing a Location for the WLAN Mobile Antenna
The location of the antenna will affect the performance of the wireless network.
Install the antenna in a outdoor location that meets the requirements described in
Table 2-1:
Table 2-1 WLAN mobile antenna location requirements
Location requirement Description
Close to the Smart-Reach
vehicle station on the vehicle.
The transmitting antenna must be within 3 feet
(1 meter) of the Smart-Reach unit on the vehicle.
Requires 3 feet (1 meter) of
clearance from other antennas.
The WLAN mobile antenna must have 3 feet
(1 meter) of clearance from any other antenna on the
vehicle, such as a GPS antenna or a radio antenna
used for onboard communication.
Requires a clear line-of-sight
view.
The onboard antenna requires a clear line-of-sight
view to the receiving antenna in the base station. The
antenna cannot be obstructed.
Important: Microwave ovens and cordless phones, for example, and other wireless
networks use the same 2.4 GHz frequency band as Smart-Reach. When too many devices
are being used simultaneously, signal interference can occur and affect performance.
