Researchers Identify Wi-Fi Dead Zones Cheaply
schliz writes "A new technique developed by HP Labs and Rice University could lower the cost of identifying 'dead zones' in large wireless networks. The technique '[combines] wireless signal models with publicly-available information about basic topography, street locations, and land use.' This enables Wi-Fi architects to test and refine their layouts cheaply before a network is deployed by focusing measurement efforts on areas that potentially could be dead zones. The technique requires only about one-fifth as many measurements as a grid sampling strategy."
The software is called Decibel Planner
All the data we use is publicly available(although not free and definitely NOT cheap).
publicly-available
Never hyphenate with an adverb ending in -ly.
