ISL37101P-EVAL Functional Overview The WLAN PCMCIA 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 3 for a list of countries and agencies that have approved the ISL37101P-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 PCMCIA 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 PCMCIA 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 3 generation offers:
Front end designed for maximum range
Higher level of chip integration and less peripheral components to reduce material costs (3-chip solution)
Support of optional IEEE 802.11 Short Preamble for significantly increased data throughput with room for additional user defined functions
Has a PCMCIA interface / Type 3A form factor A complete Reference Design for the ISL37101P is available to ensure minimum time-to-market. This information contains details for manufacturing a PCMCIA WLAN assembly, including Gerber PC board files, an accurate Bill of Material with component sourcing and complete mechanical drawings and a complete Radio Description and test plan.

These standards are designed to focus the industry to develop highly integrated, low cost, interoperable WLAN equipment, of which the ISL37101P-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 channels 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:

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 Approvals The WLAN PCMCIA will comply to the standards shown in Table 4:
