HWB3163-EVAL 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 (refer to Table 2). 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 HWB3163-EVAL for operation. The HFA3841 Media Access Controller (MAC) Protocol Handler The HFA3841 MAC 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 I chip set, the PRISM II 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) • 50% reduction in current drain for extended battery life • PCF (Point Coordination Function) • Transmitter Automatic Level Control (ALC/AGC) to provide constant RF power output • Beacon Generation in an Ad-Hoc Network • Sophisticated RAKE receiver and Automatic Gain Control (AGC) for improved multipath performance • Higher level of chip integration and less peripheral components to yield 30% reduction in material cost • Support of optional IEEE 802.11 Short Preamble for significantly increased data throughput A complete Reference Design CD, the HWB3163-CD is available to ensure minimum time-to-market.

These standards are designed to focus the industry to develop highly integrated, low cost, interoperable WLAN equipment, of which the HWB3163-EVAL is a prime example. 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 2 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: The HWB3163 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 following standards: TABLE 3.
