Al band digital radio uses Digital Mobile Radio (DMR) Tier 2 Standard protocol. It is compatible with the popular MOTO TRBO series Tier I and II using standard encryption, as well as other makes and models of DMR supported radios. It is also compatible with any existing analog two-way radio operating on the supp. Orted UHF and HVF frequencies for easy migration to digital technology. When you need to make a call, you can start the launching operation of the walkie-talkie by voice, without pressing the PTT key to liberate your hands. Application scenarios:When maintenance workers work with tools, VOX liberates hands, saving time and effort; In case of emergency, the security personnel can call the front desk with their mouth to save time. Food and beverage service staff can timely feedback problems, serving free and flexible, to prevent chaos; Traveler rocklimbing just mouth can communicate with friends to ensure safety; Cyclists can free their hands through voice control to ensure smooth and safe cycling. Digital walkie-talkie DMR protocol stipulates that the channel bandwidth used by DMR walkie-talkie is 12.5KHz. In this 12.5KHz channel bandwidth, TDMA technology can make the communication capacity doubled. This fully improves the spectrum utilization efficiency of 12.5 kHz. Using TDMA, each transmission is a carrier pulse transmission instead of continuous carrier power transmission, which can save the energy consumption of transmission and improve the life and service time of the battery. In terms of performance, with the support of TDMA technology, a single licensed 12.5KHz channel user can be doubled on the original basis. Enables the device to provide clearer voice quality over a wider range of Spaces than analog wireless. Used to set the maximum time that the intercom is allowed to transmit continuously. When the timeout expires, the radio will forcibly terminate the launch and prohibit the launch again for a period of time. Prevent the communication parties from occupying the channel for too long and ensure the reasonable use of channel resources. At the same time, limit the launch time of the interphone to prevent the damage of the interphone due to overheating. Single call, group call function. Each of us will register a DMR ID through the call sign. A group call is equivalent to a group call, which is a call between groups. In a digital contact, we can set up a group of call contacts, and all the people who choose the same group of call contacts can communicate with each other. Update the firmware of REC version.
