With the rapid development of the Internet, the network has become more and more developed, and some network devices have emerged as the times require. Such as: wireless CPE, wireless AP, wireless bridge, wireless router. So how do they differ?
The so-called wireless CPE is actually a WIFI signal receiver. Its main function is to receive WIFI signals, and then transmit the network signals to the computer through the network cable; it can be used alone; the device mode of the wireless CPE is relatively simple, and it can receive various WIFI by default. Signal, idiot-style usage patterns, less industrial usage.
A wireless AP is a WIFI signal transmitter. Its main function is to transmit WIFI signals. Mobile phones, tablet computers, wireless network card devices, etc. can receive its WIFI signals, and then connect to the Internet; it can be used alone, refer to home wireless routers; wireless The device mode of AP is relatively complex, and the point arrangement and frequency selection of the device are carried out according to different application scenarios, and there are many industrial applications.
The wireless bridge is equivalent to the combination of wireless AP + wireless CPE. The wireless bridge has the functions of transmitting and receiving wireless network signals at the same time, so the wireless bridge will have the wireless AP mode and the wireless CPE mode, which can be used according to different situations. The frequency receiving range must be set in advance, otherwise it will cause interference; the wireless bridge must be used in a set, at least 2 sets are used; the device mode of the wireless bridge is the most complicated, and can be referred to a variety of application scenarios, point layout, transmission path, There are strict requirements for frequency selection and production process, and the industry is the most used.
A wireless router is like an extended product that combines a simple wireless AP and a broadband router into one. It not only has all the functions of a simple wireless AP, such as supporting DHCP client, VPN, firewall, and WEP encryption, etc., but also includes The Network Address Translation (NAT) function supports the sharing of network connections for users on a local area network. It can realize the Internet connection sharing in the home wireless network, and realize the wireless shared access of ADSL, Cable modem and residential broadband.
