The minimum requirement for a Wi-Fi network to WiTuners is a network device, in most cases the wireless network controller or an AP, which is capable of setting and getting a set of commonly used IEEE 802.11 WLAN stats and parameters using SNMP.
How does WiTuners obtain live network management data from a WLAN?
WiTuners uses SNMP, the standard Simple Network Management Protocol, to connect to WLAN Controllers. Such a connection is protected by a log-in codes which must be provided to WiTuners by the user. The information obtainable varies with the design of the WLAN Controller. Important information elements are the MAC address of each access point and the signal strength at which it hears other access points and the throughput per access point. By repeatedly queries, WiTuners is able to construct a network performance profile that is used for generating performance alerts as necessary.
Is it possible to use live network management data to populate a WiTuners deployment map?
Yes, the AP information obtained by WiTuners can be displayed in the planning window so that the user can position the APs in the appropriate locations. This is true regardless of the APs already known to WiTuners. Therefore, this feature can also be used to update the WiTuners deployment maps with real world data without the need for a live survey. This also applies to APs belonging to other, external networks.
If some necessary input data from Wi-Fi networks is unable to be obtained, how is it handled by WiTuners?
When any parameters are not available, their corresponding IEEE 802.11 default parameters, default out-of-the-box parameters for devices or built-in default values provided by WiTuners will be applied.
