  Today, society is in an era where information and knowledge explode, and information exchange and communication between people is becoming more and more important. With the advent of the network age, networks and communication technologies such as mobile communication and wireless communication It is rapidly expanding into the lives of modern people at an unprecedented speed, and as a result, the usage and methods of electronic devices have changed with it. For example, the wireless network (wireless LAN) is the latest communication. In addition to solving wireless communication needs in people's daily life and work as a system, it also provides demands for leisure, entertainment and information organization, and people have the opportunity to use wireless network related devices More and more, especially in today's busy urban life, various new wireless network related devices are being sent out one after another, And it has become an important tool at work.

  Compared to traditional wired area networks, wireless networks certainly have a number of advantages: First, users can avoid the hassle of wiring and do not have to spend time waiting for the arrival and construction of construction personnel. Users can complete online between networks within the range of wireless network signals by simply using the relevant electronic equipment of the wireless network, and the user can access it using a notebook computer If you are free to change the location of use, without restrictions on the track, you can continue to be online with the network whether you are at home or going out, so the wireless network is very welcomed by users and the market Various high-performance, multi-functional wireless network related devices are constantly being sent out according to the needs of That.

  In order to confirm that the current location is within the radio network signal launch range, a contractor has developed a radio signal reconnaissance device for a well-known radio area network.
