Analysis of the characteristics of wireless AP and wireless router

Now the wireless devices commonly used to build wireless networks include wireless APs and wireless routers. What are the differences between these two devices? When do I use wireless APs and when do I use wireless routers?

In general, wireless routers are only required when implementing Internet access. When you need to expand the network scale, or need to connect the wireless network with the traditional LAN, you need to use the wireless AP.

In other words, in order for mobile devices to access the Internet, wireless routers are used. If you want to turn a wireless network into a wired network, or expand your current wired network, use a wireless AP.

One, wireless AP

It is a wireless access point. It has an Ethernet interface for the connection of wireless network and wired network, so as to realize the seamless integration of wireless and wired. It is equivalent to the communication bridge between wireless network and wired network. Its signal coverage is spherical. When a wireless AP is added to the network, the network coverage diameter can be expanded exponentially, and more network devices can be accommodated in the network. The wireless AP has indoor and outdoor type. Often referred to as wireless AP usually refers to the indoor type, outdoor AP requirements are higher, must have the characteristics of waterproof, lightning protection, dust and so on.

Wireless AP is usually used in a wide range of wireless coverage, such as large enterprises, companies, hotels, guesthouses, waiting halls and other places, access to more than 50 people.

For example, the wireless network in the student dormitory of Tangshan Normal University is based on Fengrunda's wireless AP (a ceiling-mounted AP and a wall-mounted AP are used together, and the entire package). Basically, each bedroom can roam. This is not a wireless router. Achieved.

The wireless AP cannot be used alone, and it often needs to be used with a wireless controller or switch networking because it has no routing function.

two. <br> <br> wireless router wireless router can be seen as a repeater, the home broadband network signals through an antenna forwarded to nearby wireless network device (laptop, cell phone support wifi, etc.). With wireless routers, Internet connection sharing in wireless networks can be achieved.

The wireless router is suitable for small-scale wireless coverage, that is, a home environment, and is inexpensive. If it is a small-area wireless coverage, the wireless router is a very affordable and convenient choice.

The wireless router can be used alone, basically bought back, connected to the Internet line, through the power, you can enjoy wifi.
