9.6. The AN-50 Advantage
The Redline AN-50 system includes several key features to mitigate the effects of
interference arising from other systems operating co-channel in the vicinity, as well as
coping with propagation anomalies such as multipath. These features include:
Advanced Error Correction
In addition to conventional forward error correction techniques, the AN-50 terminal uses
an Automatic Repeat Request (ARQ) scheme to dramatically reduce errors from
interference and multipath.
Orthogonal Frequency Division Multiplex (OFDM) Processing
The Redline OFDM technique offers tremendous robustness in the presence of harsh
multipath interference.
Narrow Beam Width
Narrow antenna beams reduce considerably the probability of interference entering the
system.
In addition to the anti-interference features described above, the AN-50 system also
holds several other competitive advantages:

9.7. Wireless
Facts
Wireless technology has existed for many years, proving itself to be a reliable
communication medium, primarily for long haul point-to-point applications supporting
critical links across the country for telephony and broadcast services. With the surge of
broadband two-way internet use, fixed wireless systems are playing an even more
important role in supporting network infrastructures.
The AN-50 system has been designed to operate in the 5.8 GHz band, which occupies
the license exempt portion of the spectrum. This allows an operator to set up a wireless
network without requiring formal consent from the regulatory agent. While this provides
great advantages in terms of cost and time to market, the ease of access to the
spectrum can bring with it undesirable effects, such as potential interference arising from
other users exploiting the "free" band. By following the simple deployment guidelines in
this manual, issues of this nature can be avoided.
