一、Overview

Relay station, in the wireless intercom communication system, is a equipment that transfers and amplifies RF signals to increase communication distance and expand coverage. Relay station, also known as “transfer station”and “differential turntable”, is an indispensable important equipment in the field of special mobile communication.

150M/400M Relay station, also known as “ground communication dispatching command system”, has the following main functions in civil aviation airport:

1. To solve the problem of insufficient signal coverage within the 8km radius of the airport, airport staff can use walkie talkies for daily ground support communication scheduling, coordinate command and emergency rescue work.

2. Solve the problem of metal structure shielding in the airport terminal building, and meet the requirements of intercom communication in the terminal building to achieve full signal coverage.

3. Other application scenarios.

4. The relay station consists of two different transmission and reception frequencies, with a frequency difference of about 1MHz.

二、Characteristic

1. Advanced RF technology: It adopts a new generation of RF technology, which has high sensitivity and high noise suppression. With the digital error correction function of the vocoder, it can transmit clear voice in the most severe noisy environment.

2. High efficiency power amplifier module: through the design of ultra large aluminum alloy heat sink, it ensures that there is no problem in continuous operation and transmission under 50W high power mode.

3. Multiple communication systems: analog/DMR/PDT/NXDN multiple communication systems, support digital and analog communication, and realize easy upgrade from analog to digital. Advanced signal processing technology is adopted to greatly improve the spectrum utilization.

4. Modular design: the modular design is adopted. The control unit, transmitting unit and receiving unit work independently, which improves the reliability of the whole machine. The professional communication power supply is built in.

5. Built in cluster controller: the controller adopts a 4-core processor, which has high computing efficiency and processing speed. It is upgraded from a conventional wireless communication system to a digital trunking wireless communication system to achieve seamless connection. Conventional IP interconnection system and digital trunking system can be established.

In addition to realizing wireless communication functions, it can also realize positioning, scheduling and other functions, and support multiple data links such as wired networks, bridges, 4G/5G wireless and satellites, reducing design and construction difficulties, and flexibly matching users' actual conditions.

6. The display is accurate and easy to operate: 2U relay station uses digital tube to display channel number, and six indicators respectively display digital analog communication type, transmission and reception status. The 3U relay station adopts a 5-inch industrial touch screen, and various parameters can be changed through a convenient operation interface, or by programming software.
