It has come to my attention that I might not have accurately or forcefully enough, explained and/or disclosed the caveats about the mapping file I announced last night. PLEASE TAKE NOTE, this is not the authoritative database for whitespace available channels and/or service areas. It is a general planning tool to allow an individual to look at an area to investigate the POSSIBILITIES of how much spectrum may be available in their given area and/or region. The FCC rules have not been completely finalized. My Google Map file did not include all the data that must be considered for the proper protections to licensed broadcasters, cable head ends, the T-Band land mobile radio cities and the radio astronomy sites around the country.
When the FCC approves the vendors for the Geo-Location database, all of these other factors not accounted for in my tool that will be properly implemented. Issues such as power and distance from the edges of existing contours will need to be made and the database will have that built in. Other issues such as the registered venues for wireless microphone users are not accounted for either. I did not create this file to then have dissimilar information or conflicting data sources as to where and on which channel is available for use. The FCC Geo-location databases will be the authoritative and only APPROVED information source. My tool was merely put out there to offer on offline method an individual could use to start investigating their possible strategies for use of TVWS. My comment about the Spectrum bridge database needing to be updated was based on the previous list comments that they had told people they were updating it based for the new rules (i.e. border protection zones with Canada and Mexico). It was not meant to insinuate their tool was not accurate and mine was. I will state this again for clarity. My mapping file is just a general tool, not an authoritative database or map file. I was not going to spend all the time required to put everything together to show all exceptions and then release a free tool. I am not looking to run a Whitespaces database or compete with anyone who has a desire to do so. I was just trying to get WISP's excited about the possibilities they have with the new spectrum.......ahh the joys of doing something for free and trying to help people out. Someone always gets their nose bent out of shape. As the saying goes, no good deed goes unpunished.
