modem utilizing the Intersil PRISM™
Direct Sequence Spread Spectrum
Wireless Transceiver chip set. This card
is made available to OEM’s (Original Equipment
Manufacturers) intending to private label or integrate the
product. It provides a sophisticated turnkey solution of
hardware and software to system providers or integrators
requiring wireless data communications capability and is ideal
for integration into computer platforms.
™

(Note 2)
• Completely Covered Assembly is Designed to Fully
Support PCMCIA’s Defined Mechanical and
Environmental Stress Conditions
• Intelligent Power Control, Including Low Power
Standby Mode
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 and sold in
standard packs of 50 units. Radio design evaluation can be
conducted by using PRISM1KIT-EVAL (PCMCIA card with an
open cover set and connector output, two cards per kit) or
WLANKITPR1-EVAL (PCMCIA card with cover set and
integrated antenna, 2 cards per kit). The card provides data
rates up to 2Mbps. Outdoor line of sight range in excess of
1000 feet has been demonstrated and indoor range of 300
feet, depending on environment, is achievable. Interoperable
Access Points are available from a number of suppliers,
enabling a total wireless network solution.
NOTES:
1. Throughout this document, all references to ‘PC Card’, ‘WLAN
adapter’, ‘adapter’, or ‘card’ refer to a covered card assembly
conforming to the mechanical size specifications of the PCMCIA
Standard Release 2.0, Type Il Extended (5.0mm) definition.
2. The range will vary in different operating environments due to effects
such as building construction.

PRISM1BRDA
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 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 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 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:
• Tech Brief TB337 “A Brief Tutorial on Spread Spectrum
and Packet Radio” [1].
For a more detailed description of radio operation, please
refer to:
• Data sheet “PRISM 2.4GHz Chip Set” [2] and:
• Application Note AN9624 “PRISM1KIT-EVAL DSSS PC
Card Wireless LAN Description” [3].

IEEE 802.11 International Agreement and
Frequency Assignments
The IEEE802 LAN committee has forged an international
agreement providing for wireless data communication
standards for the frequency range of 2.4GHz to 2.4853GHz,
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. These standards are designed to focus
the industry to develop highly integrated, low cost,
interoperable WLAN equipment, of which PRISM1BRDA is a
prime example.
There are 11 channels specified by the FCC in the 2.4GHz
to 2.4853GHz range, and one channel in the 2.471GHz to
2.497GHz range, for operation in Japan. The ETSl
(European) regulatory body conforms to the USA (FCC)
channel assignments with the exceptions of channels 1 and
2 as shown in Table 3.
The available channels of operation in the 2.4GHz to
2.4853GHz and 2.471GHz to 2.497GHz ranges are as follows:
