Hytera PDM680 MCS radio

Hytera has launched the PDM680, its first ruggedised 3GPP-compliant mission critical services (MCS) radio. It is equipped with push-to-talk (MCPTT), video (MCVideo) and data (MCData) services to support those working in challenging conditions.

The radio’s IP68 rating and MIL-STD 810H certification ensures it will continue to operate reliably in extreme environments. The radio is designed to enable first responders to hear and be heard clearly. Audio technology can reach a maximum SPL of 118 decibels. Moreover, AI-based noise cancellation, echo cancellation and wind noise cancellation technologies minimise background noise and boost audio clarity.

The radio provides eMBMS and 40 ms MCH scheduling period (MSP) functionality, which allows users to initiate a multi-cast session with a quality of service and without user congestion.

The LTE performance (TRP/TIS) of the PDM680 in key frequency bands is improved by about 2 dB compared with off-the-shelf broadband devices to help maintain stable communications even in situations with weak signals. The priority quality of service (QoS) of the HyTalk MC solution ensures first responders are given high priority over any other commercial users. With DMR technology, the PDM680 can provide device-to-device (D2D) communications whenever LTE connectivity is unavailable.

Its MCS-DMR simulcall can call both MCS devices and DMR radios simultaneously; this helps commanders initiate the MCS and the DMR calls at the same time with the press of the PTT key.
