- illumin8 16y agoThe FCC approval is based on lab-testing of a specific hardware and firmware configuration. They test it in the lab to make sure it doesn't step on other licensee's frequencies. Sometimes, just by putting a different antenna and hardware configuration on the same radio, you can cause interference, harmonics, etc, that were not present on a past model. This is why every new model of iPhone/iPad needs FCC approval before it can be sold to the public. Telling the general public that they can load whatever firmware they want on their radio ignores the fact that these radios have highly complex software algorithms affecting frequency hopping, collision detection, etc. It would be like saying "anyone on our network can modify their Ethernet firmware" and then wondering why someone took down the entire LAN because their custom firmware did a broadcast storm.
