What is the function of dmr digital walkie-talkie in supermarket?

1 The communication of DMR digital interphone is very obvious. Take the straight-through mode as an example. When DMR works with two time slots, one time slot can be used for talking, sending short messages and transmitting images, and the other time slot can be used as a control channel. This time slot can control the transmission services such as monitoring, pause, remote shooting and forced insertion that traditional analog walkie-talkie and FDMA communication cannot achieve.

2.DMR has the advantages of efficient utilization of spectrum resources, large-scale networking mode and compatibility with analog protocols. Its business functions are rich, extensible and backward compatible. At the same time, the system and terminal costs are lower, the network construction speed is faster, and the overall operation and maintenance cost is lower.
