PRISM1BRDA Functional Overview The WLAN PC Card is designed to operate in the 2.4GHz ISM frequency band, channels 1 to 11, as specified by the FCC in the USA and ETSI in Europe (refer to Table 3). The Card will also operate with reduced performance (due to filter selection) on channel 14, specified for use in Japan. Radio Transmitters must be certified in a country prior to use. Refer to Table 4 for a list of countries and agencies that have approved the PRISM1BRDA for operation. The Intersil PRISM Chip Set and AMD PCNet Mobile allows for high level integration allowing for reduced size, increased throughput, improved radio performance and faster time to market. The WLAN PC card implements Direct Sequence Spread Spectrum DSSS technology providing superior noise and signal jamming immunity including less severe impact from unintentional radiators such as microwave ovens. The user can connect the PC Card in an ad-hoc, peer-to-peer networking scheme, allowing for instant network setup in any office environment. By using an access point, the wireless LAN can be set up to allow for a greater number of users to interconnect, and to increase the coverage area. With a portal, the wireless LAN can be easily connected into an existing wired LAN, allowing for easy expansion of the service. • Random Backoff • RTS/CTS Handshake (Ready To Send/Clear To Send) and NAV Management (Network Allocation Vector) • MAC Level Acknowledgments (Media Access Control) • Re-Transmission of Unacknowledged Frames • Duplicate Detection and Rejection • Broadcast and Multicast Frames • Fragmentation and Re-Assembly • Power Management (Planned) • Timestamp Synchronization • Probe Generation • Beacon Generation in an Ad-Hoc Network • Probe Response Generation in an Ad-Hoc Network Card Information Structure The standard Intersil WLAN PC Card will be supplied with the following information embedded in the CIS. It should be noted that in most systems this information is displayed when the card is inserted.

PRISM1BRDA 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 4.
