Wi-LAN continues to stress that WiMax will encroach on patents that it asserts cover OFDM, other basic wireless technologies -- but offers RAND: Wi-LAN is trying to make it easier for companies that it expects will violate its patents, if upheld in lawsuits, that it states cover a variety of wireless standards, including implementations of 802.16, like WiMax. They're offering assurances to the IEEE that they will provide what is known as RAND -- reasonable and non-discriminatory -- licensing. This means that they have to charge a reasonable price, defined by decades of discussion over what reasonable means, and that they have to offer it to everyone, hence non-discriminatory.
