BreezeACCESS II Radio Regulatory
Standards
The systems support different "country standards" for compliance with
the applicable local radio regulations.
The country standards are configured at the factory. The country
standards determine the following:
a: Hopping frequency band and hopping sequences
b: Support of synchronization among Access Units (AU-A/E-BS units).
In some countries such synchronization is not permitted.
The following table provides a summary of the supported country
standards:

Australia 2402 to 2461
Canada 2452 to 2481
Europe ETSI * 2402 to 2480
France 2448 to 2482
Israel 2421 to 2452
Korea 2430 to 2454
Japan 2473 to 2495
Netherlands 2454 to 2468
US FCC * 2402 to 2480
Spain 2447 to 2473
Mexico 2452 to 2481
International 2402 to 2480
* Units (excluding SU-R) using US FCC country standard can be confured
to operate in HDM Mode. This enables better performance in high interfer-
ence environments by providing the ability to configure the units to use
only intreference-free channels, including hopping synchronization sup-
port.
