LMDS/FWA Backhaul
- LMDS/FWA backhaul. The Evolution Series radio is well suited for backhaul of traffic from Point-to-
MultiPoint radio access systems like WiMax. With a selectable capacity, ranging from about 6Mb/s
to 600Mb/s, the Evolution Series radio can easily be deployed in small network as well as in larger
constellations and networks with several sites linked together. The choice of pure TDM (E1/T1),
Ethernet/Gigabit Ethernet, or 155Mb/s SDH/SONET, or a combination of TDM (E1/T1) with
Ethernet/Gigabit Ethernet, makes the Evolution Series suitable for any FWA network installation.
- DSLAM backhaul. The instruction of xDSL services can in some cases uncover a new challenge. The
local transmission network may only be dimensioned for the POTS traffic and is not suited for high
speed data. Upgrading the local network to fiber might not be feasible due to time and/or cost of such
upgrade. The Evolution Series microwave radio offers an easy and flexible solution to this challenge.
The Evolution Series microwave radio can offer backhaul of the DSLAM to the optical backbone
network, whether the network interfaces are PDH, ATM/SDH/SONET or Ethernet/Gigabit Ethernet.
With the Evolution Series radio, the various traffic types are catered for merely by change of interface
modules.
