Hi, I'm looking for an index of cell phone reception for some area
within the US (preferably at least a state, and any state will do, but
in the least some reasonable area within a given state would suffice).

By index I mean to say that I'd like to be able to map locations
(whether by zip code, or longitude/latitude coordinates) to the
corresponding quality of cell phone reception.

The quality index could be some aggregate measure of reception across
carriers, or reception for one a particular carrier (assuming its a
major).

I'm not looking for the location of cell phone towers-- longitude/
latitude coordinates for towers are provided in a publically 
available FCC database (wireless.fcc.gov/geographic/fcc_db.html) 
and by various third parties as well (eg www.cellreception.com)

Data based on customer reports are okay, as long as they are
standardized and searchable.

Finally, as a rough example of what I'm looking for is this:

http://www.nyc.gov/html/doitt/downloads/pdf/mobile_phone_density.pdf

though this isn't too useful since I need the underlying data used
to produce the map (of course, I can try to get this from the NY DOITT).

Hope this wasnt too confusing,

Thank you!

taradiddle...

This page from DeadCellZones.com offers links to coverage maps
for all the major providers:
http://deadcellzones.com/carriermaps.html

You'll need to follow the links and input the city and state or
the zipcode for the areas you want to explore.

Let me know if this satisfies your interests...

Hi Sublime1, thanks for your response.  Unfortunately, my subject
heading may have been a bit misleading.  Im aware of the deadcellzones
site (as well as cellreception.com), but neither provides an
systematic index of reception quality by location.

Rather than a map, I'm actually looking for the underlying data through which
the maps might be produced.  Something that would allow me to link either
a zip code or long/lat coordinates with some measure of cell quality (either
an index or # of dead zones etc.)

The closest example of what I need is:
http://www.senate.gov/~schumer/SchumerWebsite/pressroom/press_releases/PR01334.html

But this is just a list of deadzones by city-- I was hoping for something a bit
more systematic & thorough.

I know JD Power has this data, but its not publically available.  I dont know
if this data exists, but Im guessing it does in some form or another, and I 
just havent been able to find it.

Thanks!

Try www.cellreception.com They have maps of towers and dated comments
by local users of problem areas.
