Functional Overview
The WLAN miniUSB 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 to14, 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 ISL37300U-EVAL for operation.
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 miniUSB 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 miniUSB 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.
Compared to the PRISM II chip set, the PRISM 2.5 generation
offers:
The ISL3873 Media Access Controller (MAC)
Protocol Handler
The ISL3873 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:
• CSMA /CA (Carrier Sense Multiple Access with Collision
Avoidance) with Random Backoff
• 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
• Power Management (Planned)
• Low loss front end designed for maximum range
• Higher level of chip integration and less peripheral components
to reduce material costs
• Support of optional IEEE 802.11 Short Preamble for
significantly increased data throughput with room for additional
user defined functions.
A complete Reference Design for the ISL37300U is available to
ensure minimum time-to-market. This information contains
detailes for manufacturing a miniUSB 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.

Card Information Structure
The standard Intersil WLAN miniUSB will be supplied with
information embedded in the Plug and Play (PnP) shown in Table
2. It should be noted that in most systems this information is
displayed when the card is inserted. Customization of the PnP for
specific customer requirements is available upon request, to enable
customer information to be displayed when the card is inserted.

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. These standards are designed to focus the industry to
develop highly integrated, low cost, interoperable WLAN
equipment, of which the ISL37300U-EVAL is a prime example.
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 Channel 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.
The ISL37300U is shipped with USA-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.

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.
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.
FN8022
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:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for
help.
Export restrictions
This product or software contains encryption code which may not
be exported or transferred from the US or Canada without an
approved US Department of Commerce export license.
FCC Guidelines for Human Exposure
CAUTION: To comply with FCC RF exposure
compliance, a separation distance of at least 20
cm must be maintained between the antenna of
this device and all persons
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.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 incl.
supplements A, B and C.
