What are the disadvantages and shortcomings of WLAN?
(1) performance. Wireless LAN is transmitted by radio waves. These radio waves are transmitted by wireless transmitters, and obstacles such as buildings, vehicles and trees may hinder the transmission of electromagnetic waves, thus affecting the performance of the network.
(2) speed. The transmission rate of wireless channel is much lower than that of wired channel. At present, the maximum transmission rate of WLAN is 54Mbit/s, which is only suitable for personal terminals and small-scale network applications.
(3) Safety. In essence, radio waves do not need to establish a physical connection channel, and wireless signals are divergent. Theoretically, it is easy to monitor any signal within the broadcast range of radio waves, resulting in communication information leakage.
