2Functional OverviewThe WLAN miniUSB 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 to14, where permitted bylocal regulatory authorities. Radio equipment must be certified in acountry prior to use. Refer to Table 3 for a list of countries andagencies that have approved the ISL37300U-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 miniUSB implementsDirect Sequence Spread Spectrum DSSS technology providingsuperior noise and signal jamming immunity including less severeimpact from unintentional radiators such as microwave ovens. Theuser can connect the miniUSB in an ad-hoc peer to peernetworking scheme, allowing for instant network setup in anyoffice environment. By using an access point, the wireless LANcan 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 wiredLAN, allowing for easy expansion of the service.Compared to the PRISM II chip set, the PRISM 2.5 generation offers:• Low loss front end designed for maximum range• Higher level of chip integration and less peripheral components to reduce material costs• Support of optional IEEE 802.11 Short Preamble for significantly increased data throughput with room for additional user defined functions.A complete Reference Design for the ISL37300U is available toensure minimum time-to-market. This information containsdetailes for manufacturing a miniUSB WLAN assembly, includingGerber PC board files, an accurate Bill of Material withcomponent sourcing and complete mechanical drawings and acomplete Radio Description and test plan.

3IEEE 802.11 International Agreement and Frequency 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 todevelop highly integrated, low cost, interoperable WLANequipment, of which the ISL37300U-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, channel 14 at 2.484GHz is authorized under ARIB STD-33 and Channel 1 - 13 are authorized under ARIB STD-T66. 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 3 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 ISL37300U 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 ApprovalsThe WLAN miniUSB will comply with the standards shown inTable 4:FCC Information to userThis product does not contain any user serviceable components andis to be used with approved antennas only. Any product changes ormodifications will invalidate all applicable regulatory certificationsand approvals.FCC Electronic Emission NoticesThis device complies with part 15 of the FCC Rules. Operation issubject to the following two conditions:1. This device may not cause harmful interference2.

4If 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 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 from that to which the receiver is connected.• Consult the dealer or an experienced radio/TV technician for help.Export restrictionsThis product or software contains encryption code which may notbe exported or transferred from the US or Canada without anapproved US Department of Commerce export license.FCC Guidelines for Human ExposureCAUTION: To comply with FCC RF exposure compliance, a separation distance of at least 20 cm must be maintained between the antenna of this device and all personsThe EIRP was measured for the lower, middle and highest frequencies used by the transmitter. The results in Table 5 are based on a safe distance between antenna and operator of 8 inches.The equipment therefore fulfills the requirements on power density for general population / uncontrolled exposure of 1.0 mW/cm2 and therefore complies with the requirements of FCC 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.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 Tutorial on Spread Spectrum and Packet Radio”, AnswerFAX document No. 82337.[2 ] AN9951 Application Note, Intersil Corporation, “ISL37400M-EVAL PRISM 2.5 11 Mb miniUSB Wireless LAN Radio Description”[3 ] TB337 Tech Brief, Intersil Corporation, “A Brief Tutorial on Spread Spectrum and Packet Radio”[4 ] TB382 Tech Brief, Intersil Corporation, “Measurement of WLAN Receiver Sensitivity”[5 ] AN9850 Application Note, Intersil Corporation, “Complementary Code Keying Made Simple”[6 ] AN9829 Application Note, Intersil Corporation, “Brief Tutorial on IEEE 802.11 Wireless LANs”[7] AN9820 Application Note, Intersil Corporation, “A Condensed Review of Spread Spectrum Techniques for ISM Band Systems”Further information can be found in the following:• Intersil PRISM 2.5 chipset datasheets, 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.
