Choosing a Location for the Transceivers
Placement of the FreeWave transceiver is likely to have a significant impact on its performance. The key to
the overall robustness of the radio link is the height of the antenna. In general, FreeWave units with a higher
antenna placement will have a better communication link. In practice, the transceiver should be placed away
from computers, telephones, answering machines, and other similar equipment. The 6-foot Ethernet cable
included with the transceiver usually provides ample distance for placement away from other equipment.
FreeWave offers directional and Omni directional antennas with cable lengths ranging from 3 to 200 feet.
When using an external antenna, placement of that antenna is critical to a solid data link. Other antennas in
close proximity are a potential source of interference. Use the Radio Statistics to help identify potential
problems.
An adjustment as little as 2 feet in antenna placement can resolve some noise problems. In extreme cases,
such as when interference is due to a Pager or Cellular Telephone tower, the band pass filters that FreeWave
offers may reduce this out-of-band noise.
Choosing Point-to-Point or Point-to-MultiPoint Operation
A Point-to-Point network is best suited when your network consists of one Gateway and one Endpoint
transceiver. You can add Repeaters to extend the reach of the network, but no other Gateway or Endpoint
may be added.
In a Point-to-MultiPoint network (also referred to as MultiPoint network) the transceiver, designated as a
Gateway, is able to simultaneously communicate with numerous Endpoints. In its simplest form, a MultiPoint
network functions with the Gateway broadcasting its messages to all Endpoints. If requested by the Master,
the Endpoints respond to the Gateway when given data by the device connected to the data port. This
response depends on your setup.
It is important to note the differences between Point-to-Point and MultiPoint networks. In a Point-to-Point
network all packets are acknowledged, whether sent from the Gateway to the Endpoint or from the Endpoint
