Zeroing In On Wi-Fi 'Dead Zones' To Inexpensively Fill Gaps In Wireless Networks

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 research could change that. A new test method lets engineers refine their networks using readily available information about basic topography, street locations and general land use.
