Note: Although they are all devices in WLAN, the work of wireless AP is relative. Big? The number of users supported in the environment is more than that of wireless routers, with stronger signal transceiving ability and higher requirements for wireless signal processing ability, so there are more wireless APS? Focus on wireless expansion and wireless layout? The cost invested by manufacturers is relatively high, which may be one of the main reasons why the price of wireless AP is higher than that of wireless router. You can choose a wireless AP or wireless router according to your actual needs and network conditions.
The difference between buying a wireless AP and buying a wireless router What is a wireless AP?
Wireless AP: AP is the abbreviation of access point. Wireless access node or wireless access point? It mainly provides wireless workstations to access wired LAN and wireless workstations to access wired LAN, and wireless workstations within the coverage of access points can communicate with each other through it. Generally speaking, wireless AP is a bridge between wireless network and wired network, and it is also equivalent to a wireless hub and wireless transceiver.
What is a wireless router?
Wireless router: Wireless router is a combination of wireless AP and broadband router; With the function of router, Internet connection in home wireless network can be realized, and wireless access between ADSL and residential broadband can be realized. In addition, the wireless router can assign all terminals connected wirelessly and wired through it to a subnet, so it is very convenient for various devices in the subnet to exchange data.
Divided by function
Wireless AP is equivalent to wireless switch, and can't directly connect ADSL modem. Therefore, when a switch or hub is used to obtain the IP address of the wireless network card connected to it from the router, the switch or hub must be added. Wireless bridge is also a kind of wireless AP. As the wireless router is an aggregate of AP, routing function and switch, it supports wired and wireless to form the same subnet, can directly connect to MODEM or ADSL broadband, and supports automatic dialing. Wireless router integrates some functions of AP, but it cannot realize all functions of AP.
From the application point of view
Wireless AP is widely used in companies, factories or campuses that need large-area wireless network coverage, and it is more suitable for those occasions that only need to convert wired signals into wireless signals and amplify them. Coverage is relatively large, and it can be used as a forwarding station for wireless signals, and the number of wireless clients that can be supported is also relatively large.
Wireless routers are widely used in individuals, home users and SOHO environment. Integrated wired broadband router and wireless AP, powerful management function. It can connect computers in a wired way through twisted pair, and easily realize wired and wireless communication with each other. However, the number of supported wireless clients is limited.
Product recommendation: Recommended product: D- Linkdir -605+D- LinkDWA-130.
Reference price: 423 yuan
D-Link's network products have always been very popular with consumers, and their performance and quality are quite satisfactory. Its ultra-low price 1 1N wireless package DIR-605 1 1N wireless router and DWA-1301n wireless network card combination attract consumers' attention with its fashionable appearance and outstanding quality.
D-Link DIR-605
