Wireless Operation Modes

In this chapter i will look wireless operation modes commonly used in wireless networks. When you designing network, you have requirements, what kind of mode is needed. It is a six different types of wireless operation modes . Much of the equipment manufacturers offer only some of them , but there are brands, that offer all of these modes, each of which has its own role and functions. So:

AP mode

The most basic mode of multi-function Access Point. In this mode, the AP will act as a central hub for different Wireless LAN clients. Some hotspot APs requires 802.1x authenticator function to authenticate a user before providing Internet service.

Bridge mode

In this mode, 2 access points in two remote locations connect to each other to provide a wireless bridge between 2 remote LANs. It is mostly used by enterprise to connect 2 remote office's network together. The bridge modes are connected by using either the WDS (Wireless Distribution System) or Adhoc topology.

Repeater mode

An repeater can extend the wireless coverage of another wireless AP or router.It can work with almost any wireless device.

Client mode

Also known as Ethernet Client. In this mode, the AP will act as a WLAN card to connect with the remote AP. Users can connect PC or local LAN to the Ethernet port of the client mode AP. This mode is mostly used as a CPE device for WISP subscriber.

WISP mode

In WISP mode, the AP will behave just the same as the Client mode for wireless function. However, router functions are added between the wireless WAN side and the Ethernet LAN side. Therefore, the WISP subscriber can share the WISP connection without the need for extra router.

WISP+Repeater mode

In this mode, the AP behaves virtually the same as the WISP mode, except one thing: the AP can also send wireless signal to the LAN side. That means the AP can connect with the remote WISP AP and the indoor wireless card, and then provide IP sharing capability all at the same time! However, the output power is divided between 2 wireless side and proper antenna installation can influence the performance greatly.

There are still some another operation mode types, but the basis is taken from one previously discussed.
