FreshPatents.com Antenna array configurations for high throughput mimo wlan systems
The present disclosure provides techniques for configuring multi-element antenna arrays. Such antenna arrays may be designed with slot pairs separated by ?/2 along perpendicular axes (e.g., x and y-directions).

IEEE Measurement and Modeling of the Origins of Starvation of Congestion-Controlled Flows in Wireless Mesh Networks
Significant progress has been made in understanding the behavior of TCP and congestion-controlled traffic over CSMA-based multihop wireless networks. Despite these advances, however, no prior work identified severe throughput imbalances in the basic scenario of mesh networks, in which a one-hop flow contends with a two-hop flow for gateway access. In this paper, we demonstrate via real network measurements, testbed experiments, and an analytical model that starvation exists in such a scenario; i.e., the on...

Now that Apple's long-awaited official announcement of the iPad has come and gone, Apple reviewers have had a chance to take a deep breath and take stock of what CEO Steve Jobs has delivered. In the wake of all the hype of the tablet computer as a "Jesus device," Apple fanboys and the general public were struck with an anticlimactic feeling. "Is that all there is?" many asked.
In the week or so since the announcement, the technology press has made much of the iPad's failings -- starting with jokes about f...
