PRISM1BRDA

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 PRISM1BRDA 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 PRISM1BRDA 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 PRISM1BRDA 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:
