2.4.5 Millimeter Wave Systems (Accessory)
A Millimeter Wave (MMW) system with a data rate of not less than 3 Gbps (that meets
the FlexWave Prism data rate performance and BER requirements) may be used in
applications where it is desirable or necessary to bridge an open span and where it is
impractical to lay a fiber optic cable. One MMW transceiver unit may be mounted on
the Host side of the open span and the other MMW transceiver unit may be mounted
on the Remote side of the open span. A system diagram of an MMW application is
shown in Figure 2-22. MMW systems are available from various equipment
manufacturers.
Figure 2-22. FlexWave Millimeter Wave Application
A mmw link (3GBps) is required for 12 timeslots worth of RF traffic between the Host
and the Remote. This is roughly 60 - 75MHz depending on the modulation. If a
Remote has more bandwidth requirements (such as 210MHz of RF), there would need
to be 3 point-to-point mmw links.
