WiFi Regulatory Requirements

There is a very large body of regulatory and standards requirements which need to be met by any shipping product.

This page is meant to be a non-exhaustive introduction into the topic. This must not be treated as authoritative - any company or organisation wishing to create and ship a wireless device must engage the relevant regulatory bodies and create a suitable testing/certification plan.

General Overview

There is a lot of uncertainty around what exactly is required for any given wireless device. Although the rules vary from country to country, here are some general guidelines:

(TBD: flesh out with examples to specific regulatory requirements):

NIC certification

Getting a NIC certified is a complicated task. The regulatory bodies require many things to be tested before certification is given. The following is not a complete, exhaustive list:

Device certification

In addition to the NIC requirements, there are typically device requirements. The following is not an exhaustive list.

DFS device certification

When operating in the DFS bands in 5GHz, there are also strict regulatory requirements on a number of behaviours, including:

This requires a separate certification for DFS compliance and again the entire device is tested and certified - including the processor board, wireless NICs, cabling, antenna selection, enclosure AND software.

Other reasons for transmission power limitations

There are three main reasons for limiting TX power:

WiFi standards certification


Country specific regulatory requirements


The Australian regulatory body is the ACMA (http://www.acma.gov.au). There may also be some requirements for antenna configuration and radiation patterns for fixed microwave services (TBD).
