International Classification:

H04B 17/00
H04B 7/00

US Classification:

455130, 455 6713, 4552321, 4552261, 455296

Abstract:

A wireless network device includes a signal receiving module that receives an RF signal, and a signal processing module that includes an automatic gain control (AGC) module and that generates control signals when a gain of the AGC module changes based on the RF signal. The network device includes a control module that selectively measures N time intervals between one of adjacent and non-adjacent control signals, wherein N is an integer greater than 1, and that selectively determines that the RF signal is a radar signal when the N time intervals are substantially equal.

Assignee:

Marvell International Ltd. - Hamilton

International Classification:

H04M 1/00
H04B 1/04

US Classification:

455574, 4551271, 4553431

Abstract:

A portable access point comprises a wireless LAN transceiver that selectively establishes a plurality of Ethernet wireless links with a plurality of wireless client devices, respectively. A wireless WAN transceiver establishes an Ethernet data connection with an Internet Service Provider (ISP), receives and forwards Ethernet data packets from at least one of said wireless client devices to said ISP and receives and forwards Ethernet data packets from said ISP to said one of said wireless client devices. A routing device routes Ethernet data packets between said wireless LAN transceiver and said wireless WAN transceiver. A control module controls operation of said wireless LAN transceiver and said wireless WAN transceiver. A first storage device stores operating system and application instructions for said control module.

International Classification:

H04M 1/00

US Classification:

455574, 4551271, 4551275, 4553432

Abstract:

A power-management system for wireless network devices includes a media access control module (MAC) that receives a first enable signal and based thereon selectively transmits and receives data packets. A clock generator module receives a second enable signal and based thereon selectively generates a clock signal that is communicated to the MAC. A power management module receives configuration information associated with a plurality of power savings modes. The power management module generates the first and second enable signals based on a selected one of the power savings modes and the configuration information.

Abstract:

A system includes a host interface module and a power management module. The host interface module is configured to receive configuration information from a host processor of a wireless device. The configuration information indicates that the host processor is to (i) operate in a power save mode, and (ii) in response to the wireless device receiving data of a predetermined category from a wireless network, transition from the power save mode to an active mode. The power management module is configured to generate a first signal in response to the wireless device receiving data of the predetermined category from the wireless network. The first signal transitions the host processor from the power save mode to the active mode in which the host processor processes the data of the predetermined category.
