SE820D Multi-mode Radio
SE820D PoC/PMR Multi-mode Radio
Production Introduction:
SE820D multi-mode radio integrates PoC(press-to-talk over cellular LTE/WCDMA/GSM), DMR and analog to provide public network, private network and mixed networks utilizing broad band and narrow bandwidth convergence technologies.
The PoC network is based on GSM 2G, WCDMA 3G, and LTE 4G network standards, which realize cluster communication in a wide area without distance limitation and ensure instant communication. It has multiple call modes such as group call, single call and good friends call, which can easily cope with various communication scenarios. The powerful functional trunking system adopts an exclusive management platform, which is safe and reliable, ensuring communication safety. In addition, the cluster dispatching station has a visual dispatch function, through activating GPS function, the administrator can track the location details and movement trajectories of terminal users on the APP, making cluster dispatching more accurate. Through the signal network of local sim card network carrier from local market, the radio device could cover the whole country even worldwide.
The analog part is compatible with existing conventional analogue radios. The DMR part is compatible with most of the brands such as Motorola, HYT etc. by using same vocoder AMBE++. Through the Repeater/gateway mode of this terminal, the existing digital DMR radios/conventional analogue radios could work with PoC network radios. Through two terminals working as gateway bridge, analogue UHF could work with analog VHF, DMR UHF could work with DMR VHF, analogue UHF/VHF could work with DMR UHF/VHF.
