Equipments
has been realized by physically subdividing it into two assemblies, one
for
outdoor installation (ODU) and one for indoor installation (IDU).
This
subdivision allows:
 |
–
the RF losses, due to the interconnection between ODU and the
antenna, to be minimized |
|
–
a common IDU, for all the applications to be realized. |
According
to the configurations, one or two ODUs can be equipped.The connection
between
IDU and ODU is made through a single coaxial cable.
It
is possible to use antennas with diameter dependently of the hop lenght
to be realized. |
Low Capacity Digital Radio
for Access and Mobile Applications
The low-capacity radio
systems
The main applications of
this digital radio system are:
|
– BTS <-> BTS,
BTS <-> BSC, BSC <-> MSC interconnections in mobile
networks |
|
– point-to-point
links in subscriber distribution networks |
|
– networks pertaining
to firms |
|
– emergency and/or
provisional links. |
The transmission capacity
can be:
|
– 2×2 Mbit/s |
|
– 4×2 Mbit/s |
|
– 8×2 Mbit/s |
|
– 16×2 Mbit/s. |
The 2 Mbit/s capacity,
having the channel arrangement step like the one of 2×2 Mbit/s capacity,
is derived from 2×2 Mbit/s option. According to the applications,
several RF bands are provided: :– 7
GHz– 8 GHz– 10,5 GHz– 13 GHz– 15 GHz– 18 GHz– 23 GHz– 26
GHz– 38 GHz
