RT81, Increases Your Productivity

1. What is dual time slot technology?

The DMR standard requires the use of dual time slot TDMA technology. Time division multiple access (TDMA for short) is a shared transmission medium. In radio, it allows multiple users to use the same frequency in different time slices (slots). Users are transferred rapidly, one after the other, each using their own time slice. This allows multiple users to share the same frequency.

2. The role of dual time slot technology

RT81 DMR Dual Time Slot divides the channel into two alternate time slots, thus creating two logical channels within one physical channel. Each call uses only one of the logical channels, and each user accesses a time slot as if accessing an independent channel. The transmitting walkie-talkie only sends information in its own time slot, and is idle in the other time slot. The receiving device monitors both time slots and decides which call to receive based on the signaling information contained in each time slot.

3. Advantages of dual time slot technology

①. Increased channel capacity, saving frequency cost

TDMA (Time Division Multiple Access) divides time into segments, and signals are transmitted in time segments. At the same time, the signals of the two communication groups are transmitted on the same frequency, which greatly improves the utilization rate of the frequency. It realizes the dialogue between two sets of walkie-talkies at the same frequency point, which is equivalent to increasing the capacity of the channel, and can also help users save the cost of purchasing frequency points.

②. Improve work efficiency

Utilizing dual time slot technology can help achieve faster and better communication between different groups to improve work efficiency. Using a walkie-talkie with dual time slot technology can make your timeliness better guaranteed. It will be very beneficial for industries such as hotel shopping malls and security properties.
