WLANKITPR1-EVAL
Wireless Local Area Network PC Card
The Intersil WLAN PC Card (Note 1) is
a complete wireless high speed modem
utilizing the Intersil PRISM® Direct
Sequence Spread Spectrum Wireless
Transceiver chip set. 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.
Evaluation kits include two WLAN PC cards, Windows 95
Software 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. Radio
design evaluation can be conducted by using PRISM1KITEV AL (PCMCIA card with an open co ver set and connector
output, two cards per kit) or network performance may be
evaluated by using 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 P oints are available from a number of
suppliers, enabling a total wireless network solution.

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 WLANKITPR1-EVAL 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:

IEEE 802.11 International Agreement and
Frequency Assignments
The IEEE802 LAN committee has forged an international
agreement providing for wireless data communication
standards for thefrequency range of 2.4GHz to 2.4853GHz,
as allocated bythe 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 WLANKITPR1EVAL 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:
