Licensed/unlicensed frequency management in a wireless wide-area network
InactiveUS20070026868A1Facilitate cognitionImprove spectral efficiencyRadio/inductive link selection arrangementsAutomatic exchangesLow noiseComputer science
A system and method for managing licensed and unlicensed frequency bands in a wireless wide-area network includes establishing the available channels of a licensed band and unlicensed band of frequencies. Data traffic is prioritized for assigning channels. Higher priority data traffic is assigned to the licensed frequency band and lower priority data traffic is assigned to the unlicensed frequency band. Channel quality is determined, wherein higher priority traffic is assigned to lower noise channels. Data traffic is shifted from the channels of the unlicensed frequency band to the channels of the licensed frequency band if the quality of the channels of the unlicensed frequency band deteriorates below a predetermined acceptable threshold.

The frequency manager can then control circuits that generate and provide clock signals having the selected frequency(ies) to these devices or buses. For example, in a system that is less than fully populated with devices, embodiments of the invention can select higher clock frequencies than a fully populated system would utilize. Some embodiments of the invention select higher clock frequencies for high-bandwidth devices than for low-bandwidth devices. Other embodiments use information about application programs that will be executed by systems, such as which devices these application programs will frequently access, to select higher clock frequencies for the frequently accessed devices. Yet other embodiments use information about whether the application programs are more memory or I / O intensive to allocate higher clock frequencies to either memory subsystems or I / O subsystems.
