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
ISL37400M-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 available channels of operation in the 2.4GHz to
2.4835GHz and 2.471GHz to 2.497GHz ranges are as follows:
The ISL37400M 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.
Agency and Regulatory Body Approvals
The WLAN PC Card will comply to the standards shown in
Table 4:
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.
FCC Electronic Emission Notices
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
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 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
