An access point (AP) is a device that provides wireless connectivity, allowing devices to connect to a wired network over Wi-Fi. Several network components can function as access points, either by design or with modifications. Here’s a breakdown:

Devices Designed as Access Points

1. Dedicated Wireless Access Points:

   • Purpose-built devices like the ones from Cisco, Ubiquiti, or TP-Link.
   • Often used in enterprise or home environments for seamless wireless connectivity.

2. Wireless Routers:

   • Most home and small office routers include built-in access point functionality.
   • These devices combine the functions of a router and an access point in one.

3. Wireless Range Extenders (Repeaters):

   • Devices that extend the reach of an existing wireless network.
   • They can act as simplified access points for specific areas.

Devices That Can Be Configured as Access Points

4. Wi-Fi Mesh Nodes:

   • In mesh networks, individual nodes often serve as access points, extending wireless coverage.
   • Examples include Google Nest Wi-Fi, Eero, or Linksys Velop.

5. Laptops or PCs with Wireless Adapters:

   • Computers equipped with Wi-Fi adapters can be configured as virtual access points (using software like Windows Mobile Hotspot or third-party apps).

6. Smartphones (Hotspot Mode):

   • When in hotspot mode, smartphones act as mobile access points, sharing their internet connection via Wi-Fi.

7. Switches with Wireless Modules:

   • Some advanced switches include wireless functionality, acting as an access point while managing wired connections.

Specialized Networking Hardware

8. Enterprise Gateways:
   • Gateways like those in unified threat management (UTM) solutions often include wireless access point capabilities.
9. Embedded IoT Devices:
   • Certain IoT hubs can serve as access points, especially in smart home setups.

If you’re considering converting a device to act as an access point, ensure it supports the feature and is configured correctly to avoid security vulnerabilities.
