ClientMatch Overview

ClientMatch continually monitors the RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. neighborhood for each client to provide ongoing client bandsteering and load balancing, and enhanced AP reassignment for roaming mobile clients.

Legacy 802.11a802.11a provides specifications for wireless systems. Networks using 802.11a operate at radio frequencies in the 5 GHz band. The specification uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) that is especially well suited to use in office settings. The maximum data transfer rate is 54 Mbps./b/g devices do not support ClientMatch. When you enable ClientMatch on 802.11n802.11n is a wireless networking standard to improve network throughput over the two previous standards, 802.11a and 802.11g. With 802.11n, there will be a significant increase in the maximum raw data rate from 54 Mbps to 600 Mbps with the use of four spatial streams at a channel width of 40 MHz.-capable devices, ClientMatch overrides any settings configured for the legacy bandsteering or load balancing features. 802.11ac802.11ac is a wireless networking standard in the 802.11 family that provides high-throughput WLANs on the 5 GHz band.-capable devices do not support the legacy bandsteering, station hand off or load balancing settings, so these APs must be managed on using ClientMatch.

The managed device aggregates information it receives from all APs using ClientMatch, and maintains information for all associated clients in a database. The managed device shares this database with the APs (for their associated clients), and the APs use the information to compute the client-based RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. neighborhood and determine which APs should be considered candidate APs for each client. When the managed device receives a client steer request from an AP, the managed device identifies the optimal AP candidate and manages the client’s relocation to the desired radio. This is an improvement from previous releases, where ARMAdaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment. was managed exclusively by APs, without the larger perspective of the client RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. neighborhood.

In Mobility Master/managed device deployments where APs are connected to a managed device that is associated to Mobility Master, the AP sends RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. neighborhood information to the managed device, which then forwards that information to the Mobility Master. The Mobility Master receives probe reports from all managed devices and generates a VBRVirtual Beacon Report. VBR displays a report with the MAC address details and RSSI information of an AP. for each client. These VBRs are sent from the Mobility Master to the managed device, and then to the AP to which the client is associated. APs associated to a stand-alone controller receive and collect information about clients in their neighborhood, and periodically send this information to the controller, which in turn generates VBRs and sends them directly back to the APs.

The following client or AP mismatch conditions are managed by ClientMatch:

Load Balancing: ClientMatch balances clients across APs on different channels, based upon the client load on the APs and the SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise. levels that the client detects from an underused AP. If an AP radio can support additional clients, the AP will participate in ClientMatch load balancing, and clients can be directed to that AP radio, subject to predefined SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise. thresholds.

Sticky Clients: ClientMatch also helps mobile clients that tend to stay associated to an AP despite low signal levels. APs using ClientMatch continually monitor the client RSSIReceived Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values. as it roams between APs, and moves the client to an AP when a better radio match is found. This prevents mobile clients from remaining associated to APs with a less than ideal RSSIReceived Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values., which can cause poor connectivity and reduce performance for other clients associated with that AP.

Band Steering/Band Balancing: APs using the ClientMatch feature monitor the RSSIReceived Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values. for clients that advertise dual-bandBand refers to a specified range of frequencies of electromagnetic radiation. capability. If a client is currently associated to a 2.4 GHzGigahertz. radio, and the AP detects that the client has a good RSSIReceived Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values. from the 5 GHzGigahertz. radio, the managed device attempts to steer the client to the 5 GHzGigahertz. radio, as long as the 5 GHzGigahertz. RSSIReceived Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values. is not significantly worse than the 2.4 GHzGigahertz. RSSIReceived Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values., and the AP retains a suitable distribution of clients on each of its radios.

HE Steering: 802.11ax clients are best compatible with 802.11ax capable radios, resulting in better throughput and spectral efficiency. When an 802.11ax client is associated with a lower radio, ClientMatch pushes the client to the best compatible 802.11ax radio for advanced capabilities. Though STA is in good health, and is 802.11ax capable, it still sometimes connects to lower radios. ClientMatch finds a potential 802.11ax radio on the same bandBand refers to a specified range of frequencies of electromagnetic radiation. and the client moves to the new 802.11ax radio.
