Guide: Wireless Access Points - Importance, Functionality, and Exam Tips
Importance:
Wireless Access Points (WAPs) are crucial in modern networking primarily due to increased wireless device usage. They connect wireless devices to wired networks and thereby play a key role in extending the coverage of networks and improving network performance.
Understanding WAPs:
Wireless Access Points are devices that allow wireless devices to connect to a network via Wi-Fi. They act as a gateway between wired and wireless networks. WAPs receive data from a router via an Ethernet cable and broadcast it as a Wi-Fi signal, which wireless devices can connect to.
How WAPs work:
WAPs function by connecting to a router (or switch) as a regular network device. They then convert the incoming data from the router into radio signals, which are transmitted as a Wi-Fi network. The WAP can also receive radio signals from wireless devices and convert these back into digital data for the router.
Exam Tips - Answering Questions on Wireless Access Points:
1. Understand the different protocols (802.11a/b/g/n/ac) and their characteristics.
2. Be clear on how WAPs differ from routers or switches.
3. Know the security measures like WEP, WPA, WPA2, etc.
4. Be able to identify typical use cases for WAPs and when a wired solution may be more suitable.
5. Understand the implications of WAP placement on network performance.
