170Functional OverviewThe WLAN PC Card is designed to operate in the 2.4GHz ISMfrequency band, channels 1 to 11, as specified by the FCC inthe USA. The Card will also operate on channels 12 through14, where permitted by local regulatory authorities (refer toTable 2). Radio equipment must be certified in a country prior touse. Refer to Table 3 for a list of countries and agencies thathave approved the HWB3163-EVAL for operation.The Intersil PRISM Chip Set allows for high level integrationfor reduced size, increased throughput, improved radioperformance and faster time to market. The WLAN PC cardimplements Direct Sequence Spread Spectrum DSSStechnology providing superior noise and signal jammingimmunity including less severe impact from unintentionalradiators such as microwave ovens. The user can connectthe 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 toallow for a greater number of users to interconnect, and toincrease the coverage area. With a portal (i.e., Access Point),the wireless LAN can be easily connected into an existingwired LAN, allowing for easy expansion of the service.Compared to the first generation PRISM I chip set, thePRISM 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) toprovide constant RF power output• Sophisticated RAKE receiver and Automatic GainControl (AGC) for improved multipath performance• Higher level of chip integration and less peripheralcomponents to yield 30% reduction in material cost• Support of optional IEEE 802.11 Short Preamble forsignificantly increased data throughputA complete Reference Design CD, the HWB3163-CD isavailable to ensure minimum time-to-market. This CDcontains detailed information for manufacturing a PCMCIAWLAN assembly, including Gerber PC board files, anaccurate Bill of Material with component sourcing andcomplete mechanical drawings.Related LiteratureTo learn more about what the IEEE 802.11 is, refer to:• Tech Brief TB337, Intersil Corporation, “A Brief Tutorialon Spread Spectrum and Packet Radio” [1].For a more detailed description of radio operation, pleaserefer to:• Application Note AN9864, Intersil Corporation,“HWB3163-EVAL PRISM II 11Mbps WLAN PCMCIACard User’s Guide” [2]The HFA3841 Media Access Controller(MAC) Protocol HandlerThe HFA3841 MAC and its firmware are responsible forrunning the IEEE 802.11 protocol in the WLAN card.

171IEEE 802.11 International Agreement andFrequency AssignmentsThe IEEE 802 LAN committee has forged an internationalagreement providing for wireless data communicationstandards for the frequency range of 2.4GHz to2.4835GHz, as allocated by the FCC in the USA, and in the2.471GHz to 2.497GHz frequency range, as specified bythe regulatory authority in Japan. These standards aredesigned to focus the industry to develop highly integrated,low cost, interoperable WLAN equipment, of which theHWB3163-EVAL is a prime example.In the U.S., there are 11 channels specified by the FCC inthe 2.412GHz to 2.462GHz range. In Japan, one channel at2.484GHz is authorized. The ETSl (European) regulatorybody conforms to the USA (FCC) channel assignments withthe exception that channels 12 and 13 are also allowed.Some countries in Europe, notably France and Spain haveunique channel restrictions.Although information contained in Table 2 is deemed to beaccurate, local regulatory authorities should be consultedbefore using such equipment.The available channels of operation in the 2.4GHz to2.4835GHz and 2.471GHz to 2.497GHz ranges are as follows:The HWB3163 is shipped with USA-compliant firmware. Inorder to ensure regulatory-compliant channel usage in aparticular country, special geographic-specific firmware isavailable for customer production assemblies which restrictschannel usage. Examples include ETSI-compliant firmware,etc. Since the end user does not have the ability to alter thisfirmware, regulatory compliance is ensured.Agency and Regulatory Body ApprovalsThe WLAN PC Card will comply to the following standards:3V PCMCIA Interface StandardCAUTION: This assembly is designed to operate with asupply voltage of 3.3V in laptop computers supporting thedual 3V/5V PCMCIA standard. As such, it is mechanicallykeyed with a wide tab to prevent insertion in older laptopsonly capable of supplying 5V power. Do not therefore forceengagement of the card in the PCMCIA slot of the laptop asthe computer might not be supporting the newer standard.Permanent damage may occur if operated on 5V.TABLE 2.
