AirMatch
AirMatch is a radio resource management service. AirMatch monitors radio resources on APs and supports bandwidth and Effective Isotropic Radiated Power (EIRP Effective Isotropic Radiated Power or Equivalent Isotropic Radiated Power. EIRP refers to the output power generated when a signal is concentrated into a smaller area by the Antenna.) optimization for WLAN Wireless Local Area Network. WLAN is a 802.11 standards-based LAN that the users access through a wireless connection. deployments. AirMatch allows networks to quickly adapt to changing RF Radio 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. conditions, like higher density, cochannel interference (CCI), coverage gaps, and roaming.
HPE Aruba Networking Central periodically analyzes RF data across the entire network to derive configuration changes for all deployed APs. The APs receive regular updates based on changing environmental conditions and AirMatch optimizes the channel allocation on a regular basis. For example, when a local RF event occurs, APs automatically change channels. Examples of local RF events include an increase in the noise floor or a Radar Radio Detection and Ranging. Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. detection.
AirMatch performs the following functions:
- Manage radio resources.
- Allocate channels.
- Compute channel bandwidth and EIRP.
- AirMatch automatically adjusts channel bandwidths between 20 MHz Megahertz, 40 MHz, and 80 MHz. AirMatch maximizes the system capacity and overall network efficiency. If device density increases, AirMatch automatically changes the channel bandwidth to either 40 MHz or 20 MHz. If device density decreases, AirMatch reverts the channel bandwidth to a wider channel.
- It can also fine-tune power settings to minimize large EIRP swings across neighboring APs.
- Provide a neighboring AP list to track client mobility and seamless roaming experience.
AirMatch supports the 6 GHz Gigahertz. radio in Wi-Fi Wi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. 6E APs. The 6 GHz radio in a Wi-Fi 6E AP functions along with the 2.4 GHz and 5 GHz radios. AirMatch calculates the channel and EIRP values for the 6 GHz radios. AirMatch considers only the PSC channels for radio optimization. However, if a user sets a static channel, AirMatch retains the channel irrespective of whether it is a PSC channel. AirMatch supports the 160 MHz bandwidth on the 5 GHz and 6 GHz radios of access points. Depending on the density of the network, AirMatch selects the highest bandwidth that is optimal for the network. AirMatch deploys the radios in the Wi-Fi 6E APs in the following sequence:
- 2.4 GHz
- 5 GHz
- 6 GHz
There is a 60-second time difference between deploying the 5 GHz and 6 GHz radios in Wi-Fi 6E APs.
