Microwave ovens operate at 2495 or 2450 MHz in the ISM band IEEE 802.16a. Some digital cordless telephones operate in this band too. 802.16e standards use a part of the frequency range of S band; under WiMAX standards most vendors are now manufacturing equipment in the range of 3.5 GHz. The exact frequency range allocated for this type of use varies between countries.
