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

ISL37400M-EVAL is a prime example.

In the USA, 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.

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 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.
