What is the future development trend of wireless network?

Hello, today's users' demand for wireless internet access anytime and anywhere is growing day by day, which has also become the driving force for the rapid growth of the wireless network market. However, it is undeniable that there are some defects in WIFI at present, such as roaming, billing problems, security problems caused by low internet access threshold, and there is no optimal solution. But from another aspect of technology, it is the auxiliary and supplement of high-speed wired access technology and cellular mobile communication technology, and can play an important supplementary role to 3G in a specific scope and field. The perfect combination of the two will bring broad service and development prospects. In fact, the wireless local area network supported by WIFI technology is becoming more and more popular, which also means that the WIFI technology that the public contacts will become more and more convenient. Once the WIFI network in public places solves the problems of roaming, interconnection and high charges of operators, WIFI technology will be able to better realize the transformation from technology to business. At the same time, in the application and development of WIFI technology, it should be recognized that although WIFI technology is advanced, it can not replace and have the functions of all other communication systems, so only when various access methods complement each other can it bring higher reliability and economy. In the future social life, the process of informatization will be faster and faster, and people's demand for WIFI technology will be greater and greater, so WIFI technology will have great application value and broad development prospects. WIFI technology has a huge user base in China, so it has broad market prospects and provides faster services for people's lives. Thank you.
