Hi~ I ‘m Wi-Fi Speed~ Nice to meet you~ Electromagnetic waves are transmitted at a fixed speed of light, so scientists use electromagnetic waves to produce various changes to transmit information. I’m not like the speed of a vehicle, but I, the Wi-Fi speed, means how many information I can transmit by electromagnetic waves. For example, I’m using a car with a fixed speed to transport as much packet as possible. 1. From CCK to OFDM, from 64QAM to 1024QAM, etc., we use various methods to carry out more information. 2. From HT20 to HT160, the car is designed to be wider and wider to occupying multiple lanes. 3. From one antenna to multiple antennas, the carriage is then stacked on another carriage. The above result is the dazzling rates, as shown in the following table: The more information carried; the more information lost. So how to balance reliability and efficiency in the process of data transmission?
