Adaptable Transmitting Power
Programming the MD655/MD655G allows transmitting power to be increased from 1 W up to 25 W.
Analogue and Digital Mobile Radio (Dual Mode)
With the MD655/MD655G, it is possible to configure both analogue and digital channels. This enables quick and easy movement between analogue and digital modes.
Improved Utilisation of the Frequency Spectrum
Thanks to Hytera Pseudo Trunking and the TDMA procedure, the MD655/MD655G allows the available bandwidth to be assigned to twice the number of channels. This has a clear mitigating effect on increasing spectrum scarcity.
