ISL37300P-EVAL
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
The available channels of operation in the 2.4GHz to
2.4835GHz and 2.471GHz to 2.497GHz ranges are as follows:
