ISL37101P-EVAL

PRISM

3 11 Mbps Wireless Local Area

Network PCMCIA

The Intersil ISL37101P WLAN

PCMCIA (Note 1) is a complete

wireless high speed Network Interface

Card (NIC) utilizing the Intersil

PRISM

3 Direct Sequence Spread Spectrum (DSSS)

Wireless Transceiver chip set. It provides a complete PRISM

3 reference design evaluation platform of hardware and

software to system providers or integrators requiring

wireless data communications capability and is ideal for

integration into computer platforms.

Evaluation kits include a pair of WLAN PCMCIA cards

designed to Intersil’s PRISM reference design, Microsoft

Windows

Driver, Local Area Network evaluation software,

PRISM Transmitter Test Utilities (PTTU) software (Note 3)

and documentation to get your evaluation started quickly. It

supports the IEEE 802.11b network specification for DSSS

signaling, providing data rates of 1, 2, 5.5 and 11Mbps.

Access Points are available from a number of suppliers,

enabling a total wireless network solution Typical operating

ranges are shown in Table 1.

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.
