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. To improve
the data link, FreeWave Technologies 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. The Show Radio Statistics page is found in option 4 in the
Main Menu. 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.
