Abstract
Systems and methods are provided for optimizing channel bandwidth while increasing downlink multi-user, multiple-input, multiple-output (DL MU-MIMO) gain. Depending on the access point (AP) platform, for example, APs exhibit certain characteristics regarding DL MU-MIMO gain as a function of the number of DL MU-MIMO clients associated to the AP. Accordingly, APs can be configured to operate in accordance with an algorithm that checks the number of DL MU-MIMO capable clients are associated to an AP, and dynamically switch between single- and dual-radio modes of operation to take advantage of those DL MU-MIMO gains.
Claims20
An access point (AP), comprising:
- a processor;
- and
- a memory unit operatively connected to the processor, the memory unit including instructions that when executed, cause the processor to:
- identify downlink multi-user multiple input, multiple output (DL MU-MIMO) capable clients being served by the AP, the AP capable of operating in single- or dual-radio mode;
- determine if a number of the identified DL MU-MIMO capable clients exceeds a minimum client threshold;
- in response to a determination that the number of the identified DL MU-MIMO capable clients exceeds the minimum client threshold, dynamically enable the dual-radio mode;
- in response to a determination that the number of the identified DL MU-MIMO capable clients exceeds a maximum client threshold or a determination that the number of the identified DL MU-MIMO capable clients falls below the minimum client threshold, dynamically enable the single-radio mode.
An access point (AP), comprising:
- a processor;
- and
- a memory unit operatively connected to the processor, the memory unit including instructions that when executed, cause the processor to:
- begin operation of the AP in a single-radio mode or a dual-radio mode;
- identify, in real-time, downlink multi-user multiple input, multiple output (DL MU-MIMO) capable clients associated to the AP;
- dynamically enable a dual-radio mode of the AP while a number of DL MU-MIMO capable clients remains between a specified range commensurate with known DL MU-MIMO gain characteristics of the AP;
- and
- dynamically return to the single-radio mode of operation when the number of DL MU-MIMO capable clients falls out of the specified range.
