Filed:

Appl. No.:

12/120166

Inventors:

Sid Gilbrech - Sunnyvale CA, US
Srinivas Sivaprakasam - Fremont CA, US
Srinath Sarang - Cupertino CA, US

Assignee:

Meru Networks - Sunnyvale CA

International Classification:

H04B 7/00

US Classification:

370310

Abstract:

An access point coupled to an Ethernet port detects whether it is using power over Ethernet, and if so, adjusts its operation to maintain its power requirements within those capable of being supplied by power over Ethernet. The access point might include a detector capable of determining if external power is available, or if that access point is operating using power over Ethernet. If the access point is operating using power over Ethernet, it adjusts the operation of its radios, gracefully degrading those radios from (first) both radios operating in 3×3 mode, to (second) a first radio operating in 3×3 mode and a second radio operating in 2×2 mode, to (third) both radios operating in 2×2 mode. The power adaptation circuit may also throttle clock speeds in the system (processor or peripherals), or shut down or idle various peripherals to lower power consumption for the duration consumption is high.

International Classification:

US Classification:

4555621, 4555757, 455 82, 455 83, 455121, 4551931

Abstract:

An omni-directional antenna supporting simultaneous transmission/reception, from the same AP, on multiple frequencies, allowing each AP to communicate using each possible frequency. Each AP multiplexes its outgoing signals onto its transmitting antenna, and de-multiplexes its incoming signals from its receiving antenna. The transmitting and receiving antennae are each substantially located in each other's NULL zone (or one is in the NULL zone of the other). The AP can transmit/receive on many distinct frequencies without needing more antennae.
