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. 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 Lucent Technologies 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
WaveLAN radio signals transmitted by remote antennas.
In other words: instead of having transmitting radios “scream out
louder”, Lucent Technologies WaveLAN devices are designed with
“better ears” to listen more carefully.
