IEEE 802.11 International Agreement and Frequency Assignments The IEEE802 LAN committee has forged an international agreement providing for wireless data communication standards for the frequency range of 2.4GHz to 2.4853GHz, as allocated by the FCC in the USA, and in the 2.471GHz to 2.497GHz frequency range, as specified by the regulatory authority in Japan. These standards are designed to focus the industry to develop highly integrated, low cost, interoperable WLAN equipment, of which PRISM1BRDA is a prime example. There are 11 channels specified by the FCC in the 2.4GHz to 2.4853GHz range, and one channel in the 2.471GHz to 2.497GHz range, for operation in Japan. The ETSl (European) regulatory body conforms to the USA (FCC) channel assignments with the exceptions of channels 1 and 2 as shown in Table 3. The available channels of operation in the 2.4GHz to 2.4853GHz and 2.471GHz to 2.497GHz ranges are as follows: Warranty The Intersil WLAN PC Card product is covered by a one year manufacturing warranty. Operation of the WLAN PC Card outside of the maximum ratings detailed above will make the warranty void. Agency and Regulatory Body Approvals The WLAN PC Card will comply to the following standards: TABLE 3.
