How to judge whether your digital walkie-talkie can communicate with Motorola MOTOTRBO?

Many customers who consult walkie-talkies often ask us, we are using Motorola MOTOTRBO's walkie-talkie, can your walkie-talkie communicate with the walkie-talkie we are using now?To answer this question, we need to know how to judge whether your digital walkie-talkie can communicate with Motorola. Of course, Retevis's walkie-talkies are also suitable for this judgment method.

We all know that for analog walkie-talkies, to realize the interconnection of two walkie-talkies, they need to have the same frequency, the same CTCSS and DCS. But for digital walkie-talkies, the situation is more complicated, because digital walkie-talkies have different standards , Different systems are not compatible, even devices with the same modulation method are not necessarily compatible. Therefore, in order to realize the intercommunication between digital walkie-talkies, in addition to the frequency, CTCSS DCS, it is necessary to ensure that the digital walkie-talkies have the same digital standard, same format, key or ID.

What is MOTOTRBO?

MOTOTRBO is Motorola's wireless communication system. It is a comprehensive dual-mode (analog and digital) system, including repeater, vehicle-mounted and handheld, digital applications, accessories and services, supporting industry users to easily and economically build a digital platform easily . MOTOTRBO products use 12.5kHz TDMA digital technology that complies with the European Telecommunications Standards Institute (ETSI) Digital Mobile Radio (DMR) Tier 2 standard. This is a digital walkie-talkie standard for professional communications in high-power, licensed frequency bands. TDMA can increase system capacity and spectrum efficiency by a factor of two than traditional equipment, while improving voice quality, extending battery life, and providing stronger call signaling and control capabilities for dispatch management. Using the TDMA platform, it can support more users and more information transmission in the same area and frequency.

How to determine whether our Retevis DMR digital walkie-talkie can communicate with MOTOTRBO?

A very important point is the standard. For Retevis digital walkie-talkies, as long as it can be matched with MOTOTRBO Tire I or Tier II, that is, it is just the same as the MOTOTRBO you are using, then they can communicate with each other. For example, Retevis RT81 commercial DMR Digital walkie talkie, in the description of the advertisement, indicate that it is compatible with the popular MOTO TRBO series Tier I, Tier II, then if your Motorola walkie-talkie also uses this format, then they can communicate with each other.

Note:

DMR Tier 1 refers to low-power consumer and business applications, using a maximum of 0,5W ERP. To date there are no known manufacturers of DMR Tier 1 equipment.

DMR Tier 2 covers licensed conventional radio systems and radios operating in the 66–960MHz PMR frequency bands. There are numerous manufacturers of DMR Tier 2 compliant equipment and the majority of radio systems today are also Tier 2.

DMR Tier 3 covers trunking operation in frequency bands 66–960 MHz. It supports voice and short messaging handling similar to TETRA and MPT1327.
