The difference between wireless communication and wired communication mainly lies in the different working principles, different characteristics and different applications.
First, different working principles
1, wireless communication: Wireless communication refers to the long-distance transmission communication between multiple nodes without transmission through conductors or cables, the use of radio, radio, etc., can be wireless communication.
2, wired communication: Wired communication refers to the use of metal wires, optical fibers and other tangible media to transmit information, modulation mode for baseband transmission, modulation transmission.
Second, different characteristics
1, wireless communication: construction period is short, low cost, easy to maintain.
2, wired communication: generally less interference, high reliability, strong confidentiality, but the construction cost is large.
3. Different applications
1, wireless communication: Mobile phone is one of the most widely known applications of wireless communication, wireless keyboard, mouse, wireless sensor based on Bluetooth technology.
