Typical operating ranges are shown in Table 1. TABLE 1. TYPICAL OPERATING RANGE (note 3 ) DATA RATE (Mbps) 11 5.5 2 1 INDOOR RANGE 120 feet (37 meters) 200 feet (61 meters) 240 feet (73 meters) 300 feet (91 meters) OUTDOOR RANGE 500 feet (152 meters) 800 feet (243 meters) 1300 feet (396 meters) 1750 feet (533 meters) The ISL3873 Media Access Controller (MAC) Protocol Handler The ISL3873 MAC/Baseband Processor and its firmware are responsible for running the IEEE802.11 protocol in the WLAN card. This section describes the IEEE802.11 features 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 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. Radio equipment must be certified in a country prior to use. Refer to Table 4 for a list of countries and agencies that have approved the ISL37300P-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 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 portal (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 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 IEEE802.11 Short Preamble for significantly increased data throughput * Has a Type II PC card form factor A complete Reference Design for the ISL37300P is available to ensure minimum time-to-market. This information contains details for manufacturing a PC card WLAN assembly, including Gerber PC board files, a Bill of Material with component sourcing, mechanical drawings, a detailed Radio Description with debug directions and a test plan. * Short/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) * 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 information embedded in the CIS as shown in Table 2. 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. TABLE 2.

These standards are designed to focus the industry to develop highly integrated, low cost, interoperable WLAN equipment, of which the ISL37300P-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 3 is deemed to be accurate, local regulatory authorities should be consulted before using such equipment. The ISL37300P is shipped with FCC-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 The available channels of operation in the 2.4GHz to 2.4835GHz and 2.471GHz to 2.497GHz ranges are as follows: TABLE 3. IEEE802.11 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, MKK US, CA, ETSI, MKK US, CA, ETSI, MKK US, CA, ETSI, MKK US, CA, ETSI, MKK US, CA, ETSI, MKK US, CA, ETSI, MKK US, CA, ETSI, MKK US, CA, ETSI, MKK US, CA, ETSI, MKK, FR, SP US, CA, ETSI, MKK, FR, SP ETSI, FR, MKK ETSI, FR, MKK MKK KEY: US = United States, CA = Canada, ETSI = European countries (except France and Spain), FR = France, SP = Spain, MKK = Japan Agency and Regulatory Body Approvals The WLAN PC-Card will comply to the standards shown inTable 4: TABLE 4.
