All stations are equipped with wireless network interface controllers WNICs. Wireless stations fall into two categories: wireless access points , and clients.

Access points APs , normally wireless routers , are base stations for the wireless network. They transmit and receive radio frequencies for wireless enabled devices to communicate with.

Wireless clients can be mobile devices such as laptops, personal digital assistants , IP phones and other smartphones , or non-portable devices such as desktop computers , printers, and workstations that are equipped with a wireless network interface. An independent BSS IBSS is an ad hoc network that contains no access points, which means they cannot connect to any other basic service set. Access points in an ESS are connected by a distribution system. A distribution system DS connects access points in an extended service set.

The concept of a DS can be used to increase network coverage through roaming between cells. DS can be wired or wireless. The IEEE In ad hoc mode, mobile units transmit directly peer-to-peer. In infrastructure mode, mobile units communicate through an access point that serves as a bridge to other networks such as Internet or LAN. Since wireless communication uses a more open medium for communication in comparison to wired LANs, the Many access points will also offer Wi-Fi Protected Setup , a quick but now insecure method of joining a new device to an encrypted network.

In infrastructure mode, a base station acts as a wireless access point hub, and nodes communicate through the hub. The hub usually, but not always, has a wired or fiber network connection, and may have permanent wireless connections to other nodes. Wireless access points are usually fixed, and provide service to their client nodes within range.

Wireless clients, such as laptops, smartphones etc. Sometimes a network will have a multiple access points, with the same 'SSID' and security arrangement. In that case connecting to any access point on that network joins the client to the network. In that case, the client software will try to choose the access point to try to give the best service, such as the access point with the strongest signal. An ad hoc network not the same as a WiFi Direct network [3] is a network where stations communicate only peer to peer P2P. There is no base and no one gives permission to talk.

A WiFi Direct network is another type of network where stations communicate peer to peer.

In a Wi-Fi P2P group, the group owner operates as an access point and all other devices are clients. There are two main methods to establish a group owner in the Wi-Fi Direct group. In one approach, the user sets up a P2P group owner manually. In the second method, also called negotiation-based group creation, two devices compete based on the group owner intent value.

The device with higher intent value becomes a group owner and the second device becomes a client. A peer-to-peer network allows wireless devices to directly communicate with each other. Wireless devices within range of each other can discover and communicate directly without involving central access points. This method is typically used by two computers so that they can connect to each other to form a network. This can basically occur in devices within a closed range.

If a signal strength meter is used in this situation, it may not read the strength accurately and can be misleading, because it registers the strength of the strongest signal, which may be the closest computer. IEEE The A bridge can be used to connect networks, typically of different types. A wireless Ethernet bridge allows the connection of devices on a wired Ethernet network to a wireless network.

The bridge acts as the connection point to the Wireless LAN. It allows a wireless network to be expanded using multiple access points without the need for a wired backbone to link them, as is traditionally required.
