Appl. No.:

09/598057

Assignee:

Agere Systems Inc. - Allentown PA

International Classification:

H04M 100

US Classification:

4555621, 4552771, 455273, 455 6711, 455450

Abstract:

A method and apparatus are disclosed for beam selection in a non-stationary subscriber radio unit having a multi-beam antenna array. The disclosed multi-beam antenna array acts in an omni-directional manner whenever signal-to-noise ratio (SNR) performance is sufficient, and excludes individual branches, as necessary, on the basis of SNR performance. A multi-mode approach is used to select appropriate antennas in the multi-beam antenna array. A given mode is established on the basis of the SNR of the received signal. Generally, if the SNR of the received signal satisfies predefined criteria, the non-stationary subscriber radio unit will operate the multi-beam antenna array in an omni-directional-like manner, by equally combining the received signal from each individual narrow-beam antenna branch. If the SNR of the received signal fails to satisfy the predefined criteria, the non-stationary subscriber radio unit will operate the multi-beam antenna array in a flex-beam manner that excludes those branches that have exhibited degraded SNR performance. A branch ordering table lists the branches in the multi-beam antenna array in order of their SNR performance.

International Classification:

H01Q 124

US Classification:

343702, 343872

Abstract:

The system for deploying an antenna of an integrated circuit card includes a card housing protecting electronic components, and at least one antenna. The antenna has a proximal end and a distal end, and an antenna housing protects the antenna. The antenna housing is movably connected to the card housing such that as the antenna housing moves relative to the card housing, the distal end of the antenna moves relative to the card housing.

International Classification:

H04Q 7/20

US Classification:

4554522, 455 413, 455103, 370281, 370338, 370462

Abstract:

The present invention provides a controller for use with a transceiver in a wireless communications network. In one embodiment, the controller includes a sensing system that senses, perhaps periodically, at least one characteristic associated with at least two channels of the wireless communications network. The controller further includes a modification system that updates channel information in a channel information table associated with the at least two channels based on the at least one characteristic. The controller still further includes a selection system that selects channels in accordance with the channel information.

Abstract:

The present invention provides a method of transmitting data across a communications network having multiple channels, a controller for use with a transceiver in a wireless communications network and a wireless communications device. In one embodiment, the method of transmitting data includes establishing a bandwidth for transmission of the data based on a priority status thereof, selecting a modulation scheme and symbol rate as a function of the establishing the bandwidth, concluding if at least one channel from the multiple channels provides the bandwidth and transmitting the data over the as least one channel based on the concluding.
