NOTES: 1. Throughout this document, all references to `PC Card', `WLAN adapter', `adapter', or `card' refer to a covered card assembly conforming to the mechanical size specifications of the PCMCIA Standard Release 2.0, Type Il Extended (5.0mm) definition. 2. The range will vary in different operating environments due to effects such as building construction.
Evaluation kits include two WLAN PC cards, Windows 95 Software and documentation to get your evaluation started quickly. Supporting the IEEE 802.11 network specification for Direct Sequence Spread Spectrum DSSS signaling the card is packaged in a PCMCIA Type II extended cover set. Radio design evaluation can be conducted by using PRISM1KITEVAL (PCMCIA card with an open cover set and connector output, two cards per kit) or network performance may be evaluated by using WLANKITPR1-EVAL (PCMCIA card with cover set and integrated antenna, 2 cards per kit). The card provides data rates up to 2Mbps. Outdoor line of sight range in excess of 1000 feet has been demonstrated and indoor range of 300 feet, depending on environment, is achievable. Interoperable Access Points are available from a number of suppliers, enabling a total wireless network solution.

WLANKITPR1-EVAL 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 and ETSI in Europe (refer to Table 3). The Card will also operate with reduced performance (due to filter selection) on channel 14, specified for use in Japan. Radio Transmitters must be certified in a country prior to use. Refer to Table 4 for a list of countries and agencies that have approved the WLANKITPR1-EVAL for operation. The Intersil PRISM Chip Set and AMD PCNet Mobile allows for high level integration allowing for reduced size, increased throughput, improved radio performance and faster time to market. The WLAN PC card implements Direct Sequence Spread Spectrum 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, the wireless LAN can be easily connected into an existing wired LAN, allowing for easy expansion of the service. To learn more about what the IEEE802.11 is, refer to: * Tech Brief TB337 "A Brief Tutorial on Spread Spectrum and Packet Radio" [1]. For a more detailed description of radio operation, please refer to: * Data sheet "PRISM 2.4GHz Chip Set" [2] and: * Application Note AN9624 "PRISM1KIT-EVAL DSSS PC Card Wireless LAN Description" [3]. For more specific software questions, refer to: * Application Note AN9666 "Wireless LAN Evaluation Kit SW Installation and Usage" [4]. The functions supported by the STA (station) Firmware are: * DCF (Distributed Coordination Function) * CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) * Random Backoff * 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 * Probe Generation * 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 the following information embedded in the CIS. 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.

IEEE 802.11 International Agreement and Frequency Assignments
The IEEE802 LAN committee has forged an international agreement providing for wireless data communication standards for the frequency range of 2.4GHz to 2.4853GHz, as allocated by the FCC in the USA, and in the 2.471GHz to 2.497GHz frequency range, as specified by the regulatory authority in Japan. These standards are designed to focus the industry to develop highly integrated, low cost, interoperable WLAN equipment, of which WLANKITPR1EVAL is a prime example. There are 11 channels specified by the FCC in the 2.4GHz to 2.4853GHz range, and one channel in the 2.471GHz to 2.497GHz range, for operation in Japan. The ETSl (European) regulatory body conforms to the USA (FCC) channel assignments with the exceptions of channels 1 and 2 as shown in Table 3.
