ISL37101U-EVAL

PRISM® 3 11 Mbps Wireless Local Area

Network USB

The Intersil ISL37101U WLAN USB

(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 USB 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 802.11 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.

ISL37101U-EVAL Functional Overview The functions supported by the STA (station) Firmware are: The WLAN USB 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 ISL37101U-EVAL for operation.
