Fixed Radio Systems; Point-to-point equipment; Parameters for radio systems for the transmission of digital signals operating at 38 GHz

Addition of capacities/bandwidths to existing Standard; those proposed are,16E1/E3(16QAM) in 14MHz, STM-0(32QAM) in 14MHz, 2E3(16QAM) in 28MHz, 4E3(64QAM) in 28MHz and STM-1(128QAM) in 28MHz - the proposed amendments are attached to this document. (DMC Work Item already approved by TM4). Revision of EN 300 197 for maintenance purposes as detailed in acompanying statement.
