4-2Functional 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. Radioequipment must be certified in a country prior to use. Refer toTable 3 for a list of countries and agencies that have approvedthe ISL37400M-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 II chip set, thePRISM 2.5 generation offers:• 3.3V operation for reduced power dissipation• Reduction in current drain for extended battery life• Dual antenna’s for use with Diversity circuits toimproved multipath performance• Higher level of chip integration and less peripheralcomponents to reduce material costs• Support of optional IEEE 802.11 Short Preamble forsignificantly increased data throughputA complete Reference Design for the ISL37400M isavailable to ensure minimum time-to-market.

4-3IEEE 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 theISL37400M-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 3 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 ISL37400M 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 standards shown inTable 4:FCC Information to userThis product does not contain any user serviceablecomponents and is to be used with approved antennas only.Any product changes or modifications will invalidate allapplicable regulatory certifications and approvals.FCC Electronic Emission NoticesThis device complies with part 15 of the FCC Rules.Operation is subject to the following two conditions:1. This device may not cause harmful interference2. This device must accept any interference received,including interference that may cause undesiredoperation.FCC Radio Frequency Interference statementThis equipment has been tested and found to comply withthe limits for a class B digital device, pursuant to Part 15 ofthe FCC Rules. These limits are designed to providereasonable protection against harmful interference when theequipment is operated in a commercial environment. Thisequipment generates, uses and can radiate radio frequencyenergy and, if not installed and used in accordance with theinstructions, may cause harmful interference to radiocommunications.Operation of this equipment in a residential area causeharmful interference in which case the user will be requiredto correct the interference at his own expense.If this equipment does cause harmful interference to radio ortelevision reception, which can be determined by turning theequipment off and on, the user is encouraged to try toTABLE 3.

The results in Table 5are based on a safe distance between antenna andoperator of 8 inches.The equipment therefore fulfills therequirements on power density for general population /uncontrolled exposure and therefore complies with therequirements of FCC part 15.247 (b) (4) and FCC OETBulletin 65 incl. supplements A, B and C.WARNING! Any changes or modifications of equipment not expresslyapproved by Intersil could void the user’s authority to operate the equipment.3.3V miniPCI Interface StandardCAUTION: This assembly is designed to operate with asupply voltage of 3.3V in laptop computers supporting thedminiPCI standard. As such, it is mechanically keyed toprevent improper insertion in laptops. Do not therefore forceengagement of the card in the miniPCI slot of the laptop.Permanent damage may occur if operated outside of thespecified limits listed in this document.ReferencesFor Intersil documents available on the internet, see web sitehttp://www.intersil.com/Intersil AnswerFAX (321) 724-7800.[1] TB337 Tech Brief, Intersil Corporation, “A Brief Tutorialon Spread Spectrum and Packet Radio”, AnswerFAXdocument No. 82337.[2] AN9951 Application Note, Intersil Corporation,“ISL37400M-EVAL PRISM 2.5 11 Mb miniPCI WirelessLAN Radio Description”Further information can be found in the following:• Intersil PRISM 2.5 datasheets, web home page,http://www.intersil.com/design/prism/ser-p25-11mbps.asp• IEEE 802.11 Standards Project (available from theIEEE, New York, USA).TABLE 5.
