BreezeACCESS Version 4.5 System Manual
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:
* 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
.
