Advertise LANCOM UUID

All current R&S®NC access points are multi-SSID-capable. This means that they can offer different "virtual" access points to several WLAN clients at the same time. In addition, for devices with two or more radio modules (dual radio), the BSSIDs of the logical networks refer to the corresponding radio module, but the MAC addresses of the two radio modules are completely independent of each other. This means that logical networks with different BSSIDs cannot be uniquely assigned to a device. For network monitoring and planning, however, it is useful to be able to assign the logical networks to the corresponding devices (or radio modules) using tools such as Ekahau Site Survey. R&S®NC access points have a UUID (Universally Unique Identifier), which is calculated from the device type and serial number and can uniquely identify the device in the network. However, encryption during UUID generation means that it is not possible to identify the device or serial number. This option determines whether an access point transmits its UUID.

Advertise LANCOM device name

Configures whether an access point transmits its device name. To support WLAN site survey tools, the device name of the access point can be inserted into beacons. The name is identical for all radios of a multi-radio access point, so that the individual radios can be assigned to an access point by name. The device name is coded as a vendor-specific info element as follows:
