virtual access point

(redirected from soft access point)

virtual access point

A secondary Wi-Fi hotspot created within a physical access point (AP). One or more virtual access points (logical access points) can be created for different purposes. For example, a virtual access point with one SSID could allow guest access to the Internet while another virtual AP with a different SSID could be set up for employees only. This can also be used to assign a priority to different user groups by configuring the transmission speeds up or down in each virtual AP. See VirtualWiFi and SSID.

Though the Android Wi-Fi Direct implementation does not work properly for many-to-one connections (see section 2.3) it does, however, allow for the creation of a soft access point (AP) that one or more devices can connect to simultaneously if they know its SSID and preshared key.
Since neither the SSID or preshared key of the access point can be set by the framework (both are automatically and randomly generated), they must somehow be given to the devices which are to connect to the soft access point.
The way we have accomplished this is by packing the SSID and preshared key into a network service discovery broadcast, which can be sent wirelessly from the soft access point to other devices in range using the Android Wi-Fi Direct framework.
The reason why the preshared key of the soft access point is not just directly stored beforehand is because it is randomly generated and subject to change each time the soft AP is created, at the discretion of the framework and not the programmer; there is no way to change or modify it.
With a clear, unobstructed line of sight, the wireless radios on the Android devices we tested were capable of maintaining a direct connection to a device-created soft access point at distances up to 32 to 35 meters.
Android devices acting as soft access points can extend the coverage of the network while simultaneously functioning in other capacities (such as that of a sensor node), reducing the amount of infrastructure required for deployment of the network over a given area.
All devices within range of one of these soft access points (AP) will receive this network service discovery broadcast containing the AP's SSID and PSK (see figure 1).
