Wireless AP:
AP for access point abbreviation, generally translated as "Wireless Access Node", which is mainly to provide wireless workstations to the wired LAN and wireless workstations from the wired LAN access to the wireless workstation in the access points covered by the radio station can communicate with each other. In layman's terms, wireless APs are a bridge between wireless and wired networks. Because the wireless AP coverage is an outward-spreading circular region, therefore, the wireless AP should be placed in the center of the wireless network, and the wireless client and wireless AP line distance between the best not more than 30 meters, in order to avoid the communication signal attenuation caused by excessive communication failure.
It mainly provides the wireless workstation to the wired local area network and from the wired LAN to the wireless workstation's access, in the access point coverage wireless workstation can communicate with each other through it. In a wireless network, the AP is the hub of a wired network that can connect wireless clients.
The difference between a wireless AP and a wireless router
Functionally differentiated
Wireless Ap:ap for access point abbreviation, generally translated as "Wireless Access Node", which is mainly to provide wireless workstations to the wired LAN and wireless workstations from the wired LAN to the radio station, the access points within the coverage of the wireless workstation can communicate with each other. In layman's terms, wireless APs are a bridge between wireless and wired networks. Because the wireless AP coverage is an outward-spreading circular region, therefore, the wireless AP should be placed in the center of the wireless network, and the wireless client and wireless AP line distance between the best not more than 30 meters, in order to avoid the communication signal attenuation caused by excessive communication failure.
Wireless Router: Wireless router is a combination of simple AP and broadband router, it can realize Internet Connection Sharing in home wireless network with the help of router function, and realize the wireless sharing access of ADSL and community broadband, in addition, Wireless routers can be used for wireless and wired connections through the terminals are allocated to a subnet, such as the network of various devices to exchange data is very convenient.
It can be said that: wireless router is the AP, routing functions and the collection of switches, supporting wired and wireless to form the same subnet, directly connected to the modem. The wireless AP is the equivalent of a wireless switch, connected to a wired switch or router, where the wireless card connected to it is divided into IP from the router.
Differentiate from application
Independent APs are used more in companies that require large amounts of AP to cover large areas, and all APs are connected by Ethernet and connected to separate wireless LAN firewalls.
The wireless router is used more in Soho environment, in this environment, an AP is enough. In this way, a wireless router that integrates broadband access routers and AP provides a single machine solution that is easier to manage and cheaper than two separate machines. Wireless routers generally include a network address translation (NAT) protocol to support the sharing of network connections for wireless LAN users-a function that is very useful in Soho environments. They may also have basic Firewall or packet filters to prevent port scanning software and other attacks against broadband connections. Finally, most wireless routers include a four-port Ethernet converter that can connect several wired PCs. This is convenient for managing routers or connecting a printer to a local area network.
Analysis from the topology diagram of the group network
The AP cannot be directly connected to the ADSL modem, so you must add another switch or hub when you use it: When using the topology above, the AP and the use of the No line are the same. However, the majority of wireless routers because of the ability to dial broadband, so you can directly with the ADSL modem connection for broadband sharing.
From cost analysis
802.11B wireless AP and Wireless router price difference is not much, the general wireless router will be more than 100 yuan, 802.11G depends on the specific situation, according to the brand and the different features of the difference between the two prices will have a gap of hundreds of yuan, but the cheaper product spreads is more than 100 yuan.
