Power Profile Optimization for Wi-Fi 7 APs

Feature Overview

Power Profile optimization enables the assignment of pre-defined Administrator Option Power Profiles (AOPP) to Wi‑Fi 7 Access Points (APs). These profiles let APs operate within IEEE 802.3af (15.4W), IEEE 802.3at (25.5 W) and IEEE 802.3bt (up to 90W/DC) PoE allocations by adjusting radios, MIMO chains, USB, Ethernet, IoT/BLE, and LEDs. The controller delivers the profile, which the AP applies through subsystem adjustments and driver‑level throttles. When the profile applies successfully, the AP notifies the controller and if any sub‑feature fails, the AP falls back to a safe default based on its current power mode. When only 802.3at power is available, this feature provides an option to disable the 2.4GHz radio, USB, and second Ethernet port, while boosting TX power on the 5GHz and 6GHz bands.

Assigning an AOPP may reduce AP functionality based on the selected profile, which may affect coverage, throughput, roaming, MLO, and mesh. Intersection logic mitigates these impacts by reconfiguring links, blocking incompatible operations, and preserving user settings. AOPP can be applied without rebooting the AP.

By default, no AOPP profile is applied. In this case, the AP runs in full-feature PoE mode.

The following table describes the Power Profile options:

Requirements

The following are the requirements to use the Power Profile configuration setting:

• Supported AP models: Wi‑Fi 7 APs, with current scope limited to T670 and R575 only.
• SmartZone must be running version 7.2.0 or later.
• Supported power modes:
  • 802.3bt → AOPP#0 to AOPP#4
  • 802.3at → AOPP#1 to AOPP#4

Considerations

Consider the following when configuring and using this feature:

• Each AOPP profile adjusts hardware and software subsystems such as radios, MIMO chains, transmit power, LEDs, USB, IoT, and Ethernet to operate within the selected power budget. As a result, throughput, coverage, and client behavior may vary by profile.
• Some AOPP profiles can affect radios that participate in active Multi‑Link Operation (MLO) link groups. In these cases, intersection logic evaluates the configuration and may adjust or restrict changes to prevent MLO instability.
• In mesh deployments, applying an AOPP profile that modifies required radios can affect mesh formation. The system may block or reconfigure mesh settings to align with available radio resources.
• WLANs associated with radios that are not active under the selected AOPP profile are automatically shut down. Controller‑initiated user profile operations are deferred until the required radios are available under the current AOPP state.
• When AOPP controls a subsystem, user‑initiated overrides are not permitted.
• Certain combinations of power mode, AOPP profile, and deployment topology require attention. For example, AOPP #0 requires 802.3bt/DC power, and radio reductions can introduce MLO or mesh compatibility constraints if not planned accordingly.

Limitations

Note the following limitations regarding this feature:

• Power Profiles are supported only on AP models T670 and R575.
• Power Profiles are not supported in 802.3af PoE operating mode.

Best Practices

Use the following recommendations to optimize results and configure profiles based on infrastructure requirements:

• Select AOPP#1 to AOPP#4 when restricted to 802.3at power budgets, such as during power outages. These settings implement dynamic power management, reducing the power usage and capacity of the AP.
• Select AOPP#0 only when powered by 802.3bt or DC.
• For legacy infrastructures, such as Cat5e/802.3at switch‑based networks, select AOPP#1–AOPP#4.
• For limited PoE budget, select AOPP#2 or AOPP#3 at the Zone or AP Group level.
