Zeroing in on Wi-Fi 'Dead Zones'
September 25, 2008
Rooting out Wi-Fi "dead zones" in citywide wireless networks is an expensive proposition. The paucity of techniques for mapping areas that lack coverage is an impediment, both for pre-deployment and post-deployment testing. New award-winning research from Rice University and HP Labs could change that. A test method that won best-paper honors last week at MobiCom '08 lets engineers refine their networks using readily available information about basic topography and general land use.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
