Title: Data attachment point selection
Inventor: TINNAKORNSRISUPHAP PEERAPOL
IPC: H04W48/20
Filed: 2008-06-06
Abstract: An algorithm for improving efficiency of data attachment points (DAPs) in a wireless access network (AN) is provided herein. By way of example, the algorithm can identify a serving access point (APs) coupling an access terminal (AT) to the wireless AN. A cost metric for the serving AP can be determined with respect to at least one data network access gateway (AGW) of the wireless AN. The cost metric can be compared with a similar cost metric of a current or default DAP assigned to the AT. If the cost metric of the serving AP is lower than the cost metric of the current/default DAP, the DAP can be re-assigned to the serving AP, minimizing wireless AN resource costs associated with the DAP.

Filed: 2009-02-06
Abstract: A differential low noise amplifier (LNA) is operable in a selectable one of two modes. The LNA includes a first transistor, a second transistor, a third transistor and a fourth transistor. In the first mode (PDC mode), the four transistors are configured to operate as a post-distortion cancellation (PDC) LNA. The third and fourth transistors operate as cancel transistors that improve linearity, but reduce LNA gain somewhat. In the second mode (high gain mode), the third and fourth transistors are configured so that amplified versions of the LNA input signal that they output are added to amplified versions of the LNA input signal that are output by the first and second main transistors, resulting in increased gain. Multiplexing circuits are provided within the LNA so that the LNA is configurable into a selectable one of the two modes by controlling a digital mode control signal supplied to the LNA.
