Рассмотрены характеристики и аудитория сетей профессиональной радиосвязи и критических коммуникаций. Проведен анализ используемых в России технологий профессиональной радиосвязи и перспектив развития данного сегмента телекоммуникационного рынка, произведена оценка его объемов в пятилетней перспективе. Показано, что внедряемая технология широкополосной профессиональной связи МАКВИЛ не только решает назревшие проблемы, связанные с модернизацией морально и физически устаревших систем ведомственной и корпоративной транкинговой связи, но и открывает новые возможности роста рынка услуг передачи критически важной информации. The characteristics and audience of professional mobile radio and critical communication networks are reviewed. The analysis of professional mobile radio technologies used in Russia and the prospects for the development of this segment of the telecommunications market is carried out, as well as its volume is estimated in the five-year perspective. It is shown that McWiLL broadband professional radio communication technology not only solves the urgent problems associated with the modernization of morally and physically obsolete systems of departmental and corporate trunking communications, but also opens up new opportunities for the growth of the market for critical information transmission services.

By 2020, over fifty billion devices are connected through radio communications. In conjunction with the rising of the Internet of Things (IOT) market, low power wide space networks (LPWAN) became a most well-liked low-rate long-range radio communication technology. Sigfox, LORA, and NB-IoT are the 3 leading LPWAN technologies that vie for large-scale IoT preparation. This provides a comprehensive and comparative study of these technologies that perform economical solutions to connect sensible, autonomous, and heterogeneous devices. We have a tendency to show that Sigfox and LORA are advantageous in terms of battery lifespan, capacity, and cost. Meanwhile, NB-IoT offers advantages in terms of latency and quality of service. To boot, we have a tendency to analyze the IOT success factors of these LPWAN technologies.

Radio Technology

The emergence of software radio technology is the third technological revolution in the field of communication. In view of the immature status of the application of software radio communication technology in our country's military affairs, on the premise of interpreting the connotation and extension of software radio communication technology, this paper systematically analyses the principle and architecture of software radio, and puts forward that military software radio communication technology can be used in electronic warfare simulation evaluation and software enhancement. The conception of the application of wire electronic warfare system expands the theoretical breadth of military application of software radio communication technology.

Radio Communication

The limitations of developing high-tech communication systems cause the area of people who can use this service to be uneven. One technology that can be used for areas not yet reached by this high-tech communication service is to use radio communication technology. Today radio communication technology continues to develop and produce an increasingly limited frequency spectrum. One way to improve the efficient use of available frequency spectrums is the transition from analog technology to digital technology. A very significant benefit in the use of digital technology is to save the use of radio frequency spectrum bandwidth with signal compression techniques. One device that still uses analog technology is a handy talky (HT). In addition to the lack of frequency spectrum efficiency, HT technology still requires a radio station license (ISR) for its use. This experiment designed a two-way digital audio communication system that was transmitted using the NRF24L01 radio frequency transceiver module on the 2.4Ghz frequency. Analog input data from the microphone will be converted into digital data through the ADC (Analog to Digital Converter) process using a microcontroller and the digital data that will be sent is first digitally modulated using GFSK modulation then transmitted digitally. On the other hand data that already contains voice information received again by another NRF24L01 transceiver is received by the Arduino microcontroller and then formed into a PWM signal (pulse width modulation) and then released to the speaker. So the method of using digital transmission can produce efficiencies in the frequency spectrum.
