Description of this Strong anti interference ability high confidentiality digital walkie talkie
 
The difference between a digital walkie-talkie and an analog walkie-talkie. The most widely used and widely used analog radios on the market today. The traditional analog walkie-talkie is a communication mode in which voice, signaling, and signals are modulated in a continuous wave manner to the carrier frequency of the walkie-talkie, and optimized by amplification. It has the advantages of mature technology, perfect system and relatively low cost. The shortcomings of the analog walkie-talkie are also very obvious, easy to cross-frequency, not automatically encrypted, and must be manually encrypted.
The digital walkie-talkie is a data communication mode that digitizes voice signals, uses specific digital coding methods and specific baseband modulation forms, and is optimized by a digital signal processor.
1. The first is to make better use of spectrum resources. Similar to cellular digital technology, digital walkie-talkies can load more users on a given channel and improve spectrum utilization, which is a solution to frequency crowding.
2. The second is to improve the quality of the call. Because digital communication technology has in-system error correction function, it can achieve better voice and audio quality in a wider range of signal environments than analog walkie-talkies, and it will receive less audio noise and more sound. Clear.
3. The last point is to improve and improve the integration of voice and data, and to change the weakness of the control signal as the communication distance increases. Compared with similar integrated analog voice and data systems, digital walkie-talkies can provide better data processing and interface functions, enabling more data applications to be integrated into the same two-way wireless communication base station structure for voice and data services. The integration is more complete and more convenient.
Compared with the traditional analog walkie-talkie, the voice anti-interference ability is strong, and the confidentiality is high.
Channel occupancy bandwidth is narrower
Significant advantages such as greater ability to transfer data 
 
 
Parameters of this Strong anti interference ability high confidentiality digital walkie talkie
 
LED Instruction and control
Power on : Press 3S to turn on. And then the blue light flashes every 5 seconds. Press once shortly to turn off, and the indicator close.
Bluetooth link indication : After turing on, the blue light flashes quickly for 0.5s, and the blue light flashes once in 5S after the Bluetooth linked.
Mobile charging: 5V output has not been turned off, plug and play, press the button once shortly to close the output, re-plug once to having output.
Reset: Press 5S to reset
Power off : Press the button shortly in the turn on state, all functions are off
Charging indication: No prompt when radio communication walkie talkie charging in turn off, no prompt after the full charge. When charging in turned on, the red light flashes once in 1S , and light out after the large capacity radio walkie talkie being fully charged.
Low power prompt: Turning on and discharging, the voltage is lower than 3.38V, and after the red light flashes quickly in 10 times, the output is closed and into turned off.
Turning off and discharging, the output is closed when the voltage is lower than 3.2V, and prompt low power."
SOS: Long press 5S to SOS help, the red light and blue light flash alternately every 5s, automatically close after sending 5 times. Press the button again to release the SOS.
