Hytera R9.0 Firmware

Hytera R9.0 Firmware. Hytera has recently launched a new generation of innovative features for its DMR hand portables, mobiles and repeaters. R9.0 firmware is designed to both enhance user experience and provide a greater level of flexibility. Here’s a breakdown of all the key features you should know about.


Hytera R9.0 Firmware


Full duplex call in RMO – Simultaneous voice transmission and reception in full duplex call now is available in Repeater Mode Operation (RMO) and Direct Mode Operation (DMO), which greatly enlarges full-duplex coverage beyond Trunking Mode Operation (TMO).

Advanced back-to-back connection – More powerful than traditional back-to-back connection, this new feature sends not only audio, but also signaling and data. With the Advanced Back-to-back Connection, a radio receives a bunch of cross patch calls from another system, recognising the PTT ID and receive text messages from initiator.

OTAP for conventional repeater systems – Over-the-Air Programming modifies the parameters of remote terminals through the air interface signalling, including digital conventional channel parameters and part parameters of the terminal. It saves time and manpower to operate and maintain a radio system.

Offline GPS data storage – The radio model with micro SD card inside can store offline GPS data now when you are not in the system coverage. Getting back to the office, it’s quite easy to export the offline data to the dispatch system to record the history track of a radio.

Enhanced quick GPS – Compressed GPS data can be packaged in a single frame to greatly increase the capacity up to 450 units/min, which is tripled in DMR Tier II system. This enhancement improves channel efficiency for data and reduce hardware cost.

Trunking and conventional switch – By pressing a single button or twisting the channel knob, it enables radios to be switched between trunking and conventional mode without restarting.

Optimized push-to-talk – It allows a radio to set up audio buffer and store what the user speaks before the call is established. Then it sends the stored audio together with the coming real-time audio after the call is established. Therefore, users can talk right after pressing PTT without waiting for the “go-ahead tone’’.

Out-of-range notification in RMO – A radio is always notified when it has left the repeater coverage. The users can realise if they are in the talk range all the time by paying attention to the alert tone.
