PRELIMINARY

ISL37400M-EVAL

PRISM 2.5 11Mbps Wireless Local Area

Network PC Card

The Intersil ISL37400M WLAN PC

Card (Note 1) is a complete wireless

high speed Network Interface Card

(NIC) utilizing the Intersil PRISM® 2.5

Direct Sequence Spread Spectrum Wireless Transceiver

chip set. It provides a complete PRISM 2.5 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 two WLAN PC 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.

Supporting the IEEE 802.11 network specification for Direct

Sequence Spread Spectrum DSSS signaling, the card is

packaged in a PCMCIA Type II extended cover set. The card

provides data rates of 1, 2, 5.5 and 11Mbps. Access Points

will be available from a number of suppliers, enabling a total

wireless network solution Typical operating ranges are

shown in Table 2..

Features

• FCC Certified Under Part 15 to Operate in 2.4GHz ISM

Band (Approval Pending)

Mechanical and Environmental Stress Conditions

• Intelligent Power Control, Including Low Power

Standby Mode

• Complete Reference Design, the ISL37400M is

Available to Ensure Minimum Time-to-Market

NOTES:

1. Throughout this document, all references to ‘PC Card’, ‘WLAN

adapter’, ‘adapter’, or ‘card’ refer to a card assembly conforming

to the mechanical size specifications of the miniPCI Type 3A.

2. The range will vary in different operating environments due to

effects such as building construction.

3. At present, PTTU supports Windows 95 and 98. An upgrade is in

process which will add support for NT.

Functional Overview 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. 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 ISL37400M-EVAL for operation.
PAGE 3
IEEE 802.11 International Agreement and Frequency Assignments The IEEE 802 LAN committee has forged an international agreement providing for wireless data communication standards for the frequency range of 2.4GHz to 2.4835GHz, as allocated by the FCC in the USA, and in the 2.471GHz to 2.497GHz frequency range, as specified by the regulatory authority in Japan.
