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.
The ISL3871 Media Access Controller
(MAC) Protocol Handler
The ISL3871 MAC/Baseband Processor and its firmware are
responsible for running the IEEE 802.11 protocol in the
WLAN card. This section describes the features of IEEE
802.11 that are implemented.
The functions supported by the STA (station) Firmware are:
The Intersil PRISM Chip Set allows for high level integration
for reduced size, increased throughput, improved radio
performance and faster time to market. The WLAN PCMCIA
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 PCMCIA 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 (i.e., Access Point),
the wireless LAN can be easily connected into an existing
wired LAN, allowing for easy expansion of the service.
• CSMA/CA (Carrier Sense Multiple Access with Collision
Avoidance) with Random Backoff
Compared to the PRISM II chip set, the PRISM 3 generation
offers:
• Power Management (Planned)
• Front end designed for maximum range
• DCF (Distributed Coordination Function)
• Higher level of chip integration and less peripheral
components to reduce material costs (3-chip solution)
• PCF (Point Coordination Function)
• WEP Security
• Short/Long Preamble with multirate
• RTS/CTS Handshake (Ready To Send/Clear To Send)
and NAV Management (Network Allocation Vector)
• MAC Level Acknowledgments (Media Access Control)
• Re-Transmission of Unacknowledged Frames
• Duplicate Detection and Rejection
• Broadcast and Multicast Frames
• Fragmentation and Re-Assembly
• Timestamp Synchronization
• Support of optional IEEE 802.11 Short Preamble for
significantly increased data throughput with room for
additional user defined functions
• Beacon Generation in an Ad-Hoc Network
• Has a PCMCIA interface / Type 3A form factor
Card Information Structure
A complete Reference Design for the ISL37101P is available
to ensure minimum time-to-market. This information contains
details for manufacturing a PCMCIA WLAN assembly,
including Gerber PC board files, an accurate Bill of Material
with component sourcing and complete mechanical drawings
and a complete Radio Description and test plan.
The standard Intersil WLAN PCMCIA will be supplied with
information embedded in the Card Information Structure
(CIS) shown in Table 2. It should be noted that in most
systems this information is displayed when the card is
inserted. Customization of the CIS for specific customer
requirements is available upon request, to enable customer
information to be displayed when the card is inserted.

ISL37101P-EVAL
IEEE 802.11 International Agreement and
Frequency Assignments
The IEEE 802.11WLAN 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. These
standards are designed to focus the industry to develop
highly integrated, low cost, interoperable WLAN equipment,
of which the ISL37101P-EVAL is a prime example.
The ISL37101P is shipped with FCC-compliant firmware. In
order to ensure regulatory-compliant channel usage in a
particular country, special geographic-specific firmware is
available for customer production assemblies which restricts
channel usage. Examples include ETSI-compliant firmware,
etc. Since the end user does not have the ability to alter this
firmware, regulatory compliance is ensured.
Agency and Regulatory Body Approvals
The WLAN PCMCIA will comply to the standards shown in
Table 4:
TABLE 4. COMPLIANCE STANDARDS
In the U.S., there are 11 channels specified by the FCC in
the 2.412GHz to 2.462GHz range. In Japan, channel 14 at
2.484GHz is authorized under ARIB STD-33 and channels
1-13 are authorized under ARIB STD-T66. The ETSl
(European) regulatory body conforms to the USA (FCC)
channel assignments with the exception that channels 12
and 13 are also allowed. Some countries in Europe, notably
France and Spain have unique channel restrictions.
Although information contained in Table 3 is deemed to be
accurate, local regulatory authorities should be consulted
before using such equipment.

FCC Information to User
This product does not contain any user serviceable
components and is to be used with approved antennas only.
Any product changes or modifications will invalidate all
applicable regulatory certifications and approvals.
1. This device may not cause harmful interference
2. This device must accept any interference received,
including interference that may cause undesired
operation.
FCC Radio Frequency Interference statement
This equipment has been tested and found to comply with
the limits for a class B digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This
equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications.
ISL37101P-EVAL
Operation of this equipment in a residential area may cause
harmful interference in which case the user will be required
to correct the interference at his own expense.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following
measures:
3.3V PCMCIA Interface Standard
CAUTION: This assembly is designed to operate with a
supply voltage of 3.3V in laptop computers supporting the
PCMCIA standard.
CAUTION: Do not force engagement of the card in the
PCMCIA slot. It is mechanically designed to prevent
improper insertion.
Permanent damage may occur if operated outside of the
specified operating limits listed in this document.
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
References
• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.

FCC Guidelines for Human Exposure
The EIRP was measured for the lower, middle and highest
frequencies used by the transmitter. The results in Table 5
are based on a safe distance between antenna and
operator of 8 inches (20 centimeters).The equipment
therefore fulfills the requirements on power density for
general population / uncontrolled exposure of 1.0 mW/cm2
and therefore complies with the requirements of FCC part
15.247 (b) (4) and FCC OET Bulletin 65 including
supplements A, B and C.
