PART NUMBER DESCRIPTION CARDS/SET HWB3163-EVAL WLAN Evaluation Kit 2 Data Sheet November 1999

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 (refer to Table 2). Radio equipment must be certified in a country prior to use. Refer to Table 3 for a list of countries and agencies that have approved the HWB3163-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 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 (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 first generation PRISM I chip set, the PRISM II generation offers:

• 3.3V operation for reduced power dissipation
• 50% reduction in current drain for extended battery life
• Transmitter Automatic Level Control (ALC/AGC) to provide constant RF power output
• Sophisticated RAKE receiver and Automatic Gain Control (AGC) for improved multipath performance
• Higher level of chip integration and less peripheral components to yield 30% reduction in material cost
• Support of optional IEEE 802.11 Short Preamble for significantly increased data throughput A complete Reference Design CD, the HWB3163-CD is available to ensure minimum time-to-market. This CD contains detailed information for manufacturing a PCMCIA WLAN assembly, including Gerber PC board files, an accurate Bill of Material with component sourcing and complete mechanical drawings.
