Application of bluetooth technology in professional walkie-talkies

Overview

Bluetooth is a low-power, short-range wireless communication technology. As a small-range wireless communication standard, Bluetooth has the advantage that electronic devices can be wirelessly connected to each other through Bluetooth, eliminating the need for traditional cable connections.

The standard of Bluetooth is IEEE802.15, which works on the 2.4GHz ISM (industrial, scientific, medical) frequency band, and the center frequency is 2.45GHz, which saves users the trouble of applying for and paying for the use of the frequency band. However, in the 2.4GHz frequency band, Wi-Fi, HomeRF, microwave ovens, cordless phones and other electronic devices share the same frequency band. In theory, interference is inevitable. In order to prevent mutual interference with other devices, Bluetooth adopts a series of measures such as Adaptive Frequency Hopping (AFH) and power control, so as to ensure Bluetooth communication and avoid interfering with other communication.

Bluetooth Solutions

1. Professional users

Traffic Police - The use of Bluetooth shoulder microphone or Bluetooth headset combined with Bluetooth PTT can get rid of the cable, make the traffic police more convenient, and will not affect the call when driving a motorcycle. As long as the Bluetooth technology is within the effective range, it can penetrate some obstacles and connect devices at any angle, so the platform can be placed in the trunk of the motorcycle, which greatly enhances the convenience and concealment;

Patrol - Domestic patrol officers are equipped with more. Walkie-talkie + Bluetooth shoulder microphone or Bluetooth headset + Bluetooth PTT, which can make the patrol officer get rid of the cable and focus on the road conditions;

Police car-car station with bluetooth shoulder microphone or bluetooth headset + bluetooth PTT, on the one hand, you can achieve hands-free calls in the car, on the other hand, you can leave the police car about 10 meters in case of a situation and still maintain communication. Communication with dispatch center;

Plainclothes Police - Requires a real-time intercom call, and at the same time has a very high requirement for concealment. Ordinary walkie-talkies are easy to expose the target, but wearing a Bluetooth headset can not reveal traces;

Port-crane, trailer platform with bluetooth shoulder microphone or bluetooth headset + PTT, can facilitate the user's operation and improve efficiency.

2. Business users

Hotels, restaurants - require neat and professional clothing. The application of the walkie-talkie combined with the Bluetooth headset or the Bluetooth shoulder microphone and the Bluetooth PTT can liberate the hands and enhance the professional image;

Construction, logistics and transportation - in the occasions with high overall requirements, with the application of Bluetooth headset or Bluetooth shoulder microphone, Bluetooth PTT can free your hands,

3. Special industries

Special industries - Bluetooth shoulder microphone or Bluetooth headset of walkie-talkie can keep hands free and work at the same time to reduce the radiation damage caused by walkie-talkie to human brain. The Bluetooth headset or Bluetooth shoulder microphone of walkie-talkie can keep a distance of about 10 meters from the main body of the walkie-talkie. With smooth communication, there will be humanistic care for the physiology and psychology of specific groups of people in special industries.

Client Benefits

Replacing the cable: The walkie-talkie or the car can be connected to the Bluetooth PTT and the Bluetooth shoulder microphone or Bluetooth headset, and get rid of the cable entanglement of the wired shoulder microphone or the wired headset.

Free your hands: Keep the conversation uninterrupted while you are working. The Bluetooth shoulder microphone of the walkie-talkie or the Bluetooth headset provides hands-free convenience. Even if you hold the steering wheel of the car with both hands, the Bluetooth technology can ensure that your conversation is uninterrupted.

Reduce power consumption: Bluetooth is a low-power wireless communication technology, and the power consumption of Bluetooth headsets is about 10mA. When the walkie-talkie uses the Bluetooth shoulder microphone or Bluetooth headset to talk, the speaker of the walkie-talkie can be turned off, thus reducing the power consumption of the walkie-talkie.

Good concealment: Use Bluetooth point-to-point wireless transmission to replace wired connection lines, and can penetrate obstacles, so as to realize real-time concealed communication of two-way voice and data transmission.

Reduce radiation: According to the relevant departments, the radiation value of Bluetooth headsets is only a few tenths of that of mobile phones (the transmission power of ordinary mobile phones is generally 0.5 watts), which is almost negligible and can be used with confidence. It has become quite popular in Europe and the United States. .
