Copyright © Intersil Americas Inc. 2001, All Rights Reserved 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. 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 3 for a list of countries and agencies that have approved the ISL37400M-EVAL for operation. The HFA3841 Media Access Controller (MAC) Protocol Handler The ISL3874 MAC/Baseband Processor and its firmware are responsible for running the IEEE 802.11 protocol in the WLAN card. This section describes the features of IEEE 802.11 that are implemented. The functions supported by the STA (station) Firmware are: 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 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 (i.e., Access Point), the wireless LAN can be easily connected into an existing wired LAN, allowing for easy expansion of the service. • CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) with Random Backoff Compared to the first generation PRISM II chip set, the PRISM 2.5 generation offers: • Power Management (Planned) • 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 (Media Access Control) • Re-Transmission of Unacknowledged Frames • Duplicate Detection and Rejection • Broadcast and Multicast Frames • Fragmentation and Re-Assembly • Timestamp Synchronization • 3.3V operation for reduced power dissipation • DCF (Distributed Coordination Function) • Reduction in current drain for extended battery life • PCF (Point Coordination Function) • Dual antenna’s for use with Diversity circuits to improved multipath performance • Beacon Generation in an Ad-Hoc Network • Higher level of chip integration and less peripheral components to reduce material costs • Support of optional IEEE 802.11 Short Preamble for significantly increased data throughput A complete Reference Design for the ISL37400M is available to ensure minimum time-to-market. This information contains detailesfor manufacturing a miniPCI WLAN assembly, including Gerber PC board files, an accurate Bill of Material with component sourcing and complete mechanical drawings. • Probe Response Generation in an Ad-Hoc Network Card Information Structure The standard Intersil WLAN PC Card will be supplied with information embedded in the CIS shown in Table 2. It should be noted that in most systems this information is displayed when the card is inserted. Customization of the CIS for specific customer requirements is available upon request, to enable customer information to be displayed when the card is inserted. TABLE 2. CIS EMBEDDED INFORMATION FUNCTION NAME Related Literature To learn more about what the IEEE 802.11 is, refer to: • Tech Brief TB337, Intersil Corporation, “A Brief Tutorial on Spread Spectrum and Packet Radio”[1].

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. The ISL37400M is shipped with USA-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 PC Card will comply to the standards shown in Table 4: TABLE 4. COMPLIANCE STANDARDS In the U.S., there are 11 channels specified by the FCC in the 2.412GHz to 2.462GHz range. In Japan, one channel at 2.484GHz is authorized. 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.

FCC Radio Frequency Interference statement KEY: US = United States, CA = Canada, ETSI = European countries (except France and Spain), FR = France, SP = Spain, MKK = Japan 4-3 This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. Operation of this equipment in a residential area cause harmful interference in which case the user will be required to correct the interference at his own expense. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
