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 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 por tal (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 first generation PRISM I chip set, the PRISM II generation offers: · 3.3V operation for reduced power dissipation · 50% reduction in current drain for extended battery life · Transmitter Automatic Level Control (ALC/AGC) to provide constant RF power output · 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 · Suppor t 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. This CD contains detailed information for manufacturing a PCMCIA WLAN assembly, including Gerber PC board files, an accurate Bill of Material with component sourcing and complete mechanical drawings.
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: · CSMA / CA (Carrier Sense Multiple Access with Collision Avoidance) with Random Backoff · WEP Security · Shor t/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 · 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
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. Customization of the CIS for specific customer requirements is available upon request, to enable customer information to be displayed when the card is inserted.

HWB3163-EVAL IEEE 802.11 International Agreement and Frequency Assignments
The IEEE 802 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 industr y 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:
TABLE 2. IEEE 802.11 CHANNELS CHANNEL NUMBER 1 2 3 4 5 6 7 8 9 10 11 12 13 14 CHANNEL FREQUENCY 2412MHz 2417MHz 2422MHz 2427MHz 2432MHz 2437MHz 2442MHz 2447MHz 2452MHz 2457MHz 2462MHz 2467MHz 2472MHz 2484MHz GEOGRAPHIC USAGE US, CA, ETSI US, CA, ETSI US, CA, ETSI US, CA, ETSI US, CA, ETSI US, CA, ETSI US, CA, ETSI US, CA, ETSI US, CA, ETSI US, CA, ETSI, FR, SP US, CA, ETSI, FR, SP ETSI, FR ETSI, FR Japan
The HWB3163 is shipped with USA-compliant firmware. In order to ensure regulatory-compliant channel usage in a par ticular 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:

3V PCMCIA Interface Standard
CAUTION: This assembly is designed to operate with a supply voltage of 3.3V in laptop computers supporting the dual 3V/5V PCMCIA standard. As such, it is mechanically keyed with a wide tab to prevent insertion in older laptops only capable of supplying 5V power. Do not therefore force engagement of the card in the PCMCIA slot of the laptop as the computer might not be supporting the newer standard. Permanent damage may occur if operated on 5V.
KEY: US = United States, CA = Canada, ETSI = ETSI countries (except France and Spain), FR = France, SP = Spain.
In Japan, authorization for Channels 1 through 11 is pending.
