FEATURED STORY

Award-winning technique inexpensively finds gaps in wireless networks

Zeroing in on Wi-Fi "dead zones"
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, street locations and general land use.
