Introduction
When you read about wireless outdoor products, you will often encounter the
terms “output power” of the radio and “gain” of the antenna equipment as
measures for the “strength” of the transmitted signal.
■
Output Power of radio equipment is often subject to maximum limits as
defined by local radio regulations (see Appendix G “Certified Outdoor
Solutions”). 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.
The Avaya Inc. outdoor solution is 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 receive quality of Avaya Wireless
radio signals transmitted by remote antennas.
