Introducing R9.0 Firmware
A New Generation of DMR Radios
Introducing R9.0 Firmware
Hytera has launched a new generation of innovative features for its Digital Mobile Radio (DMR) portfolio including repeaters, mobile and portable radios. These exciting new features are designed to both enhance the user experience and provide greater versatility. The R9.0 Firmware also removes certain features that are no longer supported by Hytera. Read the brochure to find out why you should upgrade to R9.0 Firmware today. ( Existing devices should be upgraded to Hytera’s iM or iS firmware before being used as part of a system. To upgrade your Hytera devices, contact one of our approved Dealer Partners. )
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). It greatly enlarges full-duplex coverage beyond Trunking Mode Operation (TMO); long calls are made hands-free and much more efficiently between radios, and even between radios and phones.
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. It also establishes remote RF link between sites; through serial port back-to-back connection to repeater, the mobile transmits signal, data and voice. Data relays through serial port interconnection between the mobile and repeater. With this new feature, Hytera control station can provide RF link for the repeater network when there is no solid backhaul connection.
OTAP for Conventional Repeater System
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 & 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. During this process, registration & deregistration in trunking system is done automatically, and over the air authentication is still available.
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’’. This feature also enhances the handover function without dropping communications in Tier III system during sites switch.
Out-of-range Notification in RMO
A radio is always notified when it has left the repeater coverage. The users can realize if they are in the talk range all the time by paying attention to the alert tone.
