4.5 WILCS02 Regulatory Domain

The WILCS02 regulatory domain configurations include gain tables, channel information, and more, in the device. The Hardware Unit Test (HUT) application writes multiple sets of regulatory gain values. This configuration regulates the RF transmission power in the firmware during Wi-Fi® operation. There are a total of six slots reserved in the Non-Volatile Memory (NVM) area for writing regulatory domain configurations. Each slot signifies different domain restrictions with Microchip Technology Inc. (MCHP) defined regulatory country codes.
Note: The labels (GEN, USA, EMEA, and more) are default regions typically programmed by Microchip for module products.

The tables comply with the set of rules and policies governing spectrum usage with configurations such as country code, calibration channel, band-edge channel, and output power settings for a Wi-Fi device in a specific area of operation as configured.

The following are the configurable regulatory domains in the WILCS02:

  • GEN: Gain table for worldwide module.
  • USA: Gain table for North America based on regulatory limits. This follows the United States Federal Communications Commission (FCC).
  • EMEA: Gain table for Europe based on regulatory limits.
