When designing and selecting a microwave radio solution, the implementer must balance a
number of tradeoffs to ensure reliable service. The physical attributes (link length,
antenna size) along with the RF parameters (frequency, modulation scheme, power, and
bandwidth) must be properly chosen so the payload is successfully transported to end of
the link. With previous generations of radios, these parameters had to be fixed prior to
installation, resulting in potential operational risk, as well as limited flexibility and
bandwidth growth.  The new generation of digital microwave radios provides flexible options for the user. SAS has harnessed this technology to enable converged service solutions in a variety of fixed
and mobile deployments.
 

The digital radios currently available provide flexible operation both at the RF and interface
level. At the RF level, the modulation type, occupied bandwidth, and transmit power are
configurable. This allows the user to tailor the operation of the radio as desired to satisfy
spectrum, payload, and reliability requirements.
 

 Upgrading your existing cable system to support high quality digital video and HDTV is
available and cost effective. The digital upgrade can occur channel by channel and allows the
new digital channels to coexist with the legacy analog channels. The digital channels not only
provide a significant improvement in viewing quality, but also provide a 6-10 fold gain in the
number of channels (6-10 digital channels per analog channel).
