Data taken using custom proprietary antennas in a custom proprietary laptop computer. The ISL3874 Media Access Controller (MAC) Protocol Handler The ISL3874 MAC/Baseband Processor and its firmware are responsible for running the IEEE802.11 protocol in the WLAN card. This section describes the features of IEEE802.11 that are implemented. The functions supported by the STA (station) Firmware are: • CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) with random backoff • WEP security • Short/long preamble with multirate • RTS/CTS handshake (ready to send/clear to send) and NAV management (network allocation vector) • MAC level acknowledgments • Retransmission of unacknowledged frames • Duplicate detection and rejection • Broadcast and multicast frames • Fragmentation and re-assembly • Power management (planned) • Timestamp synchronization • DCF (distributed coordination function) • PCF (point coordination function) • Beacon generation in an ad-hoc network • Probe response generation in an ad-hoc network Functional Overview The WLAN miniPCI is designed to operate in the 2.4GHz ISM frequency band, channels 1 to 11, as specified by the FCC in the USA. The card will also operate on channels 12 through 14, where permitted by local regulatory authorities. Radio equipment must be certified in a country prior to use. Refer to Table 4 for a list of countries and agencies that have approved the ISL37400M-EVAL for operation. The Intersil PRISM Chip Set allows for high level integration for reduced size, increased throughput, improved radio performance and faster time to market. The WLAN miniPCI implements 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 miniPCI 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 (i.e., Access Point), the wireless LAN can be easily connected into an existing wired LAN, allowing for easy expansion of the service. Compared to the PRISM II chip set, the PRISM 2.5 generation offers: • Low-loss front end designed for maximum range • Higher level of chip integration and less peripheral components, reducing material costs • Support of optional IEEE802.11 Short Preamble for significantly increased data throughput with room for additional user-defined functions • Has a miniPCI interface/Type 3A form factor A complete reference design for the ISL37400M is available to ensure minimum time-to-market. This information contains details for manufacturing a miniPCI WLAN assembly, including Gerber PC board files, an accurate bill of material with component sourcing and complete mechanical drawings and a complete radio description and test plan. Card Information Structure The standard Intersil WLAN miniPCI will be supplied with information embedded in the Plug and Play (PnP) shown in Table 2. It should be noted that in most systems this information is displayed when the card is inserted. Customization of the PnP for specific customer requirements is available upon request, to enable customer information to be displayed when the card is inserted. 2 ISL37400M-EVAL TABLE 2.

IEEE802.11 CHANNELS (Continued) CHANNEL NUMBER CHANNEL FREQUENCY GEOGRAPHIC USAGE IEEE802.11 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 2.4835GHz, 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 the ISL37400M-EVAL is a prime example. In the USA, there are 11 channels specified by the FCC in the 2.412GHz to 2.462GHz range. In Japan, channel 14 at 2.484GHz is authorized under ARIB STD-33 and channels 1-13 are authorized under ARIB STD-T66. The ETSl (European) regulatory body conforms to the USA (FCC) channel assignments with the exception that channels 12 and 13 are also allowed. Some countries in Europe, notably France and Spain have unique channel restrictions. Although information contained in Table 3 is deemed to be accurate, local regulatory authorities should be consulted before using such equipment. The available channels of operation in the 2.4GHz to 2.4835GHz and 2.471GHz to 2.497GHz ranges are as follows: TABLE 3. IEEE802.11 CHANNELS CHANNEL NUMBER 1 2 3 4 5 6 7 CHANNEL FREQUENCY 2412MHz 2417MHz 2422MHz 2427MHz 2432MHz 2437MHz 2442MHz GEOGRAPHIC USAGE US, CA, ETSI, MKK KEY: US = United States, CA = Canada, ETSI = European countries (except France and Spain), FR = France, SP = Spain, MKK = Japan The ISL37400M is shipped with FCC-compliant firmware. In order to ensure regulatory-compliant channel usage in a particular country, special geographic-specific firmware is available for customer production assemblies which restricts channel usage. Examples include ETSI-compliant firmware, etc. Since the end user does not have the ability to alter this firmware, regulatory compliance is ensured. Agency and Regulatory Body Approvals The WLAN miniPCI will comply to the standards shown in Table 4: TABLE 4.
