Adaptive Modulation Radio
Two types of AMR (Hit type and Hitless type) are under development.
Even hit type, the interruption time is small (<300msec), then there is no problem of using it to the current mobile network.
The system from 48E1(32QAM) to 20E1(QPSK)or from 40E1(16QAM) to 20E1(QPSK) can be selected.System gain is improved 13.5dB or 9dB by changing the system above.
Combination of E1 and Ethernet signal transmission is available.
The normal ODU can be used for this application.
