• Single-mast series setup
Typical performance of each relay cell (in Ground-Wave
propagation conditions above flat terrain):
- Range: 24 km, 30 Ch @ 2 ms, Real time.
- Range: 10 km, 120 Ch @ 2 ms, Real time.
For the single-mast series setup, a special software configuration needs
to be programmed in the LRUs, using an FDPA408 pocket terminal or
the 408UL HCI workstation: in each intermediate pair, not to have one
of the LRUs transmitting while the other is receiving, you must have
them working on two distinct “
Subframes
”. That’s why the date rate is
divided by two in the above example.
