Term
|
Definition
| A metric computed and used by the DCA algorithm to determine the potential performance that is possible on each channel that APs are using, as well as channels that they potentially could use. |
|
|
Term
|
Definition
| An area that is left without good RF coverage. |
|
|
Term
| coverage hole detection mitigation (CHDM) |
|
Definition
| An RRM algorithm that can automatically detect areas of weak RF coverage and compensate by increasing AP transmit power levels. |
|
|
Term
| coverage overlap factor (COF) |
|
Definition
| A metric computed by the RRM FRA algorithm that indicates the percentage of an AP’s cell area that has overlapping coverage from other neighboring APs. |
|
|
Term
| dynamic bandwidth selection (DBS) |
|
Definition
| A criteria used by the DCA algorithm to maximize throughput by changing an AP’s channel width in a dynamic fashion. |
|
|
Term
| dynamic channel assignment (DCA) |
|
Definition
| An RRM algorithm that monitors APs in an RF group and adjusts their channel assignment based on poor RF conditions. |
|
|
Term
| Event-driven RRM (ED-RRM) |
|
Definition
| Normal RRM algorithms that are triggered by an event such as detecting a source of interference or a rogue device, rather than running periodically. |
|
|
Term
| flexible radio assignment (FRA) |
|
Definition
| An RRM algorithm that can automatically detect an AP that is providing redundant 2.4GHz coverage and can reassign that AP to offer added coverage in the 5GHz band or monitor RF conditions. |
|
|
Term
| neighbor discovery protocol (NDP) |
|
Definition
| A Cisco proprietary protocol used by APs to advertise their presence, allowing other neighboring APs to discover them. |
|
|
Term
| radio resource management (RRM) |
|
Definition
|
|
Term
| receiver start of packet threshold detection (RxSOP) |
|
Definition
| A Cisco proprietary feature that can apply a threshold to APs such that received signals with an RSSI lower than the threshold will be ignored. |
|
|
Term
|
Definition
| A logical grouping of wireless LAN controllers that operates as a single RF domain. |
|
|
Term
|
Definition
| A controller that is elected to handle all of the RRM algorithms for the entire group on a single frequency band. |
|
|
Term
|
Definition
| A policy of RRM-related RF parameters that can be applied to a logical grouping of APs in an RF group. |
|
|
Term
| transmit power control (TPC) |
|
Definition
| An RRM algorithm that automatically adjusts the transmit power level of APs to minimize cell overlap and interference. |
