The ISL3873 Media Access Controller
(MAC) Protocol Handler
The ISL3873 MAC/Baseband Processor and its firmware are
responsible for running the IEEE802.11 protocol in the
WLAN card. This section describes the IEEE802.11 features
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
Functional Overview
• Short/Long Preamble with multirate
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 4 for a list of countries and agencies that have approved
the ISL37300P-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 PC card
implements 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
(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:
• Low-loss front end designed for maximum range
• 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)
• Timestamp Synchronization
• DCF (Distributed Coordination Function)
• Beacon Generation in an Ad-Hoc Network
• Probe Response Generation in an Ad-Hoc Network
Card Information Structure
The standard Intersil WLAN PC card will be supplied with
information embedded in the CIS as 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.
• Higher level of chip integration and less peripheral
components to reduce material costs

IEEE802.11 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
2.4835GHz, 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
ISL37300P-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, one channel at
2.484GHz is authorized. 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 ISL37300P 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 available channels of operation in the 2.4GHz to
2.4835GHz and 2.471GHz to 2.497GHz ranges are as follows:
The WLAN PC-Card will comply to the standards shown
