One of the most important developments in the walkie-talkie industry is the integration of advanced features and technologies. Traditionally, walkie-talkies were simple two-way radios with limited range and functionality.

With the help of repeaters, maintaining a reliable and stable communication network has become easier than ever before. So, let's take a closer look at the use and characteristics of repeaters.

​The newly launched industrial and commercial multi-standard cluster explosion-proof terminal-Q8088 intercom of the YSHON explosion-proof intercom series is designed in strict accordance with China's latest explosion-proof electrical standards.

​One of the biggest advantages of DMR radios is their ability to transmit digital audio signals. Unlike analog signals, digital audio signals are less likely to be distorted by background noise or interference from other radios.

​A wireless walkie-talkie is a portable communication device that can communicate wirelessly in places without network coverage. Wireless walkie-talkies are often used in situations where instant communication is required, such as outdoor adventures, construction sites, security industries, etc.
