Determining Range & Clearance

Other Considerations

Other Considerations

In most literature concerning wireless outdoor products, two parameters are usually listed to indicate transmitted signal strength: output power of the radio, and gain of the antenna system.

Output Power of radio equipment is often subject to maximum limits as defined by local radio regulations. Consequently Output Power is not by definition the way to enhance wireless performance.

High gain antennas are larger in size than low gain antennas, and are characterized by a narrow focus of the radio beam. These two characteristics make it more difficult to aim the antennas, and/or adjust antenna alignment to optimize the performance of the wireless point-to-point link.

With these points in mind, the design of antennas and components supplied with the RoamAbout Outdoor Kit are based upon the following principles:

An output power and antenna gain that comply with the maximum limits as defined by local governing bodies concerning radio transmissions.

Enhanced radio sensitivity for optimal reception of RoamAbout radio signals transmitted by remote antennas.

Refer to Appendix D - Calculating Range & Clearance for detailed information to help you calculate the optimal range of your antenna system.
