2Functional OverviewThe WLAN PC-Card is designed to operate in the 2.4GHz ISMfrequency band, channels 1 to 11, as specified by the FCC in the USA.The card will also operate on channels 12 through 14, where permittedby local regulatory authorities. Radio equipment must be certified in acountry prior to use. Refer to Table 4 for a list of countries andagencies that have approved the ISL37300P-EVAL for operation.The Intersil PRISM Chip Set allows for high level integration forreduced size, increased throughput, improved radio performanceand faster time to market. The WLAN PC-card implements DirectSequence Spread Spectrum DSSS technology providing superiornoise and signal jamming immunity including less severe impactfrom unintentional radiators such as microwave ovens. The usercan connect the PC-card in an ad-hoc peer to peer networkingscheme, allowing for instant network setup in any officeenvironment. By using an access point, the wireless LAN can beset up to allow for a greater number of users to interconnect, and toincrease the coverage area. With a portal (i.e. Access Point), thewireless 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 generationoffers:• Low loss front end designed for maximum range• Higher level of chip integration and less peripheral componentsto reduce material costs• Support of optional IEEE 802.11 Short Preamble forsignificantly increased data throughput• Has a Type II PC Card form factorA complete Reference Design for the ISL37300P is available toensure minimum time-to-market. This information contains detailsfor manufacturing a PC Card WLAN assembly, including GerberPC board files, a Bill of Material with component sourcing,mechanical drawings, a detailed Radio Description with debugdirections and a test plan.Related LiteratureTo learn more about what the IEEE 802.11 is, refer to:• Tech Brief TB337, Intersil Corporation, “A Brief Tutorial onSpread Spectrum and Packet Radio”[1].For a more detailed description of radio operation, please refer to:• Application Note AN9968, Intersil Corporation, “ISL37300P-EVAL PRISM 2.5 PCMCIA Wireless LAN Radio Description”[2]The ISL3873 Media Access Controller (MAC)Protocol HandlerThe ISL3873 MAC/Baseband Processor and its firmware areresponsible for running the IEEE 802.11 protocol in the WLANcard. This section describes the features of IEEE 802.11 that areimplemented.The functions supported by the STA (station) Firmware are:• CSMA/CA (Carrier Sense Multiple Access with CollisionAvoidance) with Random Backoff•WEPSecurity• Short/Long Preamble with multirate• RTS/CTS Handshake (Ready To Send/Clear To Send) and NAVManagement (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)• Beacon Generation in an Ad-Hoc Network• Probe Response Generation in an Ad-Hoc NetworkCard Information StructureThe standard Intersil WLAN PC Card will be supplied withinformation embedded in the CIS shown in Table 2. It should benoted that in most systems this information is displayed when thecard is inserted. Customization of the CIS for specific customerrequirements is available upon request, to enable customerinformation to be displayed when the card is inserted.IEEE 802.11 International Agreement andFrequency AssignmentsThe IEEE 802 LAN committee has forged an internationalagreement providing for wireless data communication standardsfor the frequency range of 2.4GHz to 2.4835GHz, as allocated bythe FCC in the USA, and in the 2.471GHz to 2.497GHzfrequency range, as specified by the regulatory authority inJapan. These standards are designed to focus the industry toTABLE 2.

3develop highly integrated, low cost, interoperable WLANequipment, of which the ISL37300P-EVAL is a prime example.In the U.S., there are 11 channels specified by the FCC in the2.412GHz to 2.462GHz range. In Japan, one channel at 2.484GHzis authorized. The ETSl (European) regulatory body conforms tothe USA (FCC) channel assignments with the exception thatchannels 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 beaccurate, local regulatory authorities should be consulted beforeusing such equipment.The available channels of operation in the 2.4GHz to 2.4835GHz and2.471GHz to 2.497GHz ranges are as follows:The ISL37300P is shipped with USA-compliant firmware. In orderto ensure regulatory-compliant channel usage in a particularcountry, special geographic-specific firmware is available forcustomer production assemblies which restricts channel usage.Examples include ETSI-compliant firmware, etc. Since the enduser does not have the ability to alter this firmware, regulatorycompliance is ensured.Agency and Regulatory Body ApprovalsThe WLAN PC-Card will comply to the standards shown in Table4:FCC Information to userThis product does not contain any user serviceable componentsand is to be used with approved antennas only.

4equipment off and on, the user is encouraged to try to correct theinterference 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 fromthat to which the receiver is connected.• Consult the dealer or an experienced radio/TV technician forhelp.FCC Guidelines for Human ExposureThe EIRP was measured for the lower, middle and highestfrequencies used by the transmitter. The results in Table 5 arebased on a safe distance between antenna and operator of 8inches. The equipment therefore fulfills the requirements onpower density for general population / uncontrolled exposure of1.0 mW/cm2and therefore complies with the requirements ofFCC part 15.247 (b) (4) and FCC OET Bulletin 65 incl.supplements A, B and C.WARNING! Any changes or modifications of equipment not expressly approved byIntersil could void the user’s authority to operate the equipment.3.3V PC-card Interface StandardCAUTION: This assembly is designed to operate with a supplyvoltage of 3.3V in laptop computers supporting the PC Cardstandard.CAUTION: Do not force engagement of the card in the PC Cardslot. It is mechanically designed to prevent improper insertion.Permanent damage may occur if operated outside of the specifiedoperating limits listed in this document.ReferencesFor Intersil documents available on the internet, see web sitehttp://www.intersil.comorIntersil AnswerFAX (321) 724-7800.[1] TB337TechBrief, Intersil Corporation, “A Brief Tutorial onSpread Spectrum and Packet Radio”, AnswerFAX documentNo. 82337.[2] AN9968 Application Note, Intersil Corporation, “ISL37300P-EVAL PRISM 2.5 PCMCIA Wireless LAN RadioDescription”[3] TB382 Tech Brief, Intersil Corporation, “Measurement ofWLAN Receiver Sensitivity”[4] AN9850 Application Note, Intersil Corporation,“Complementary Code Keying Made Simple”[5] AN9829 Application Note, Intersil Corporation, “BriefTutorial on IEEE 802.11 Wireless LANs”[6] AN9820 Application Note, Intersil Corporation, “ACondensed Review of Spread Spectrum Techniques for ISMBand Systems”Further information can be found in the following:• Intersil PRISM 2.5 data sheets, web home page,http://www.intersil.com/design/prism/ser-p25-11mbps.asp• IEEE 802.11 Standards Project (available from the IEEE,New York, USA).TABLE 5.
