Sistemet Radio Fikse; Pajisjet pikë-pikë; Sistemet radio dixhitale me kapacitet të lartë që transmetojnë STM-4 ose 4 x STM-1 në një kanal radiofrekuence 40 MHz që përdor Kanalin-Co Binar të Polarizuar (CCDP)

Fixed Radio Systems; Point-to-point equipment; High capacity digital radio systems transmitting STM-4 or 4 x STM-1 in a 40 MHz radio frequency channel using Co-Channel Dual Polarized (CCDP) operation

Scope

The present document defines technical parameters for a high capacity Digital Radio Relay System (DRRS) operating in frequency bands with 40 MHz channel spacing e.g. the 4 GHz, 5 GHz, U 6 GHz and 11 GHz bands. The capacity should be STM-4 or 4 × STM-1 per 40 MHz RF-channel by using both polarizations in the co-channel dual polarized (CCDP) mode of operation.
