Definition: A wireless access point (WAP) is a wireless network device that can connect to a wired network or the internet, and provide wireless network access. It is typically used to provide Wi-Fi network. WAPs can also be referred to as wireless routers.

 

Function: A wireless AP can perform the following functions:

 

Provide wireless network access: A WAP can provide wireless network access, allowing users to connect to the network via wireless devices such as laptops, smartphones, tablets, etc.

 

Manage network traffic: A WAP can manage network traffic to ensure network stability and reliability. For example, it can limit the bandwidth usage for each user to prevent network congestion.

 

Provide network security: A WAP can provide some network security, such as using WPA2 encryption to protect the network, or using MAC address filtering to restrict network access.

 

Extend network coverage: A WAP can extend the coverage of an existing wired network. This can be achieved through wireless repeaters or bridges.

 

Security: Wireless APs typically have the following security features:

WPA2 encryption: WPA2 is a network encryption protocol that can protect wireless networks from hackers and unauthorized access.

 

MAC address filtering: A WAP can restrict network access to only authorized devices by filtering the MAC addresses that can connect to the network.

 

Firewall: A WAP can use a built-in firewall to protect the network from malicious attacks and virus infections.

 

VPN support: A WAP can support VPN connections to provide a higher level of encryption and security.
