Some of the current LobbyByFax alerts include:
Stop
our Interstate Highways from being tolled!: Send a fax to Congress
demanding that they do not allow tolls to be placed on free Interstates.
We all pay a gas tax, we should not be taxed again with tolls! (As
Pennsylvania is doing with I-80)
Stop
funding for Congestion Pricing in New York City and elsewhere: States
should address congestion issues by providing better transportation
services and alternatives for everyone, and not by charging effective
tolls so that only the wealthiest commuters may drive to work!
Stop the
Recording Industry: The heavyhanded approach of the recording industry
to block copying via digital rights management is a cheap attempt to have
Congress and thus the American public pay for the failed policies of the
Recording Industry. We should not tolerate, and Congress should not allow,
the onerous restrictions which the Industry wishes to impose upon us, as
the cost and loss of utility which such restrictions will create are
incalculably greater than the minimal benefit in terms of higher profits
which will be generated for the Industry.
Rebuild
the Twin Towers of the World Trade Center: Although current plans to
rebuild the World Trade Center provide for a moderately tall, 1,776 foot
"Freedom Tower", the skyline of New York City will never be restored
without a rebuilding of the Twin Towers of the WTC, and anything short of
this goal will forever remain a tacit concession to those who destroyed
them.

General:
This list strives to provide a detailed and accurate list of cellular
service drops or other service/quality related issues on the combined
ATTWS/Cingular GSM networks.
We generally like the GSM protocol as it seems to offer to
closest approximation to analog cellular or traditional (POTS)
landline service without the "electronic", "mechanized" sounding
distortion found with many other digital cellular protocols and the least
amount of latency (the time delay from when you speak into a digital
cellular phone to when you are heard on the other end; if two cell phones
are involved or a VoIP phone is involved then the delay can be much
longer).
We find both the delay and the distortion to be distractive, annoying,
and not at all conducive to normal conversation that one would expect on
a traditional landline (or analog cellular) phone. Thus, there is a
distinct preference for GSM over CDMA, TDSMA, iDEN and other digital
protocols as it seems to be the least affected by these issues.
However, despite what ATT/Cingular claim on countless billboards as to
their having the "Fewest Dropped Calls" in a given market, we tend to
find that as compared to Verizon (which has it's share of problems; see
the Verizon Digital
Cellular Drop List and the Verizon Express Network Data
Drops List), ATT/Cingular has a significantly greater
number of dropped, distorted, muted, or otherwise problematic areas,
those of which we have detected are summarized herein.
Criteria:
The criteria for a drop being "worthy" :) of getting posted are:
- Drop occurs at least 3 times traveling in the same direction (i.e.,
Eastbound on a given road)
- Drops occur over a period of more than a month, e.g., if a drop or
difficulty is detected on 05/01/2005 it still needs to drop or evidence
the given difficulty on 06/01/2005 in order to be posted.
- Drops are moving drops in areas of strong coverage,
i.e., these aren't "I can't get coverage when I sit in my living room
corner" situations, but areas where there is otherwise good coverage and
the phone just for no apparent reason drops. (This isn't just for
motorists; we've also had problems on Amtrak and commuter rail services,
etc.)
- Drops are in areas of otherwise good coverage, e.g.,
the drops listed are not in regional areas where ATT/Cingular has/have no
coverage. Thus, there are no posts saying "My AT&T GSM or Cingular GSM
call dropped on I-91 crossing the MA/VT line" since ATT/Cingular doesn't
cover there, yet.
Please feel free to submit your drop/reset experiences with Verizon which
meet the above guidelines so that we can provide a more comprehensive
list. Contact information for this list is
provided at the end of this page.
Additionally, if you feel that an item is incorrect, please let us know the
specifics of your experiences in the given area so we can test it and modify
the list accordingly.
Thanks!
Disclaimer/Note: The authors have
nothing to do with ATT/Cingular other than using a few of their phones
and/or data products as paying subscribers. While we will try to
keep these lists current, you should test them out for yourself and not
use this as a dispositive and authoritative source of information as to
ATT/Cingular's cellular service (or lack thereof). In other words, these are
just our and/or other's observations -- we try to be accurate, but we make
no representations other than what we have observed (and if others notice
we are wrong about a given drop or cellular/data service difficulty, please
mail us so we can test the drop and modify the list accordingly.)
Ordering Note: Lists proceed from north to south. As
coverage while driving is based on roads which often cross state boundaries,
we needed to choose some order of presentation, and we opted for north to
south, and then east to west. Thus, similar to the Federal Highway numbering
system (e.g., "US-1, US-2, US-99, US-101, etc.), and thus states in the
Northeast start the list, and states in the West/Southwest are located
towards the end.
Cingular Dropped Call List by State
Massachusetts
Charlton: Drops occur on the Mass Pike between Mile Markers 91 and 88.
Drops only seem to occur perhaps 80% of the time. Most recent instance
occurred on 03/11/2007.
Rhode Island
West Greenwich: Drops occur while driving on I-95 between Mile Marker 14
and Mile Marker 16 near the JCT of I-95 and RI-3 (which is the exit is for
West Greenwich and Coventry). Most recent instance occurred on 08/09/2007.
Connecticut
Union: Drops occur while driving eastbound on I-84 approaching
Exit 74, south of Sturbridge, approx. 1 mile south of the MA/CT state line.
Most recent instance occurred on 03/11/2007.
Windsor: Drops occur on I-91 at the Bradley Airport connector (which is
CT-20) at Mile Marker 48.2. Most recent instance occurred on 05/13/2007.
Hartford: Calls drop just north of Hartford on I-91 and slightly south
of exit 35 (which is the JCT of I-91 and I-291) while traveling north. Most
recent instance occurred on 10/30/2006.
Bristol: Drops occur on I-84 at the JCT of CT-72. Last occurred on
03/24/2006.
New Britain: Drops occur on I-84 while traveling west at the JCT of
CT-72 East. Most recent instance occurred on 07/13/2006.
Wethersfield/Rocky Hill: Drops occur at the JCT of I-91 and CT-99 (which
is the Silas Deane Hwy). Most recent instance occurred on 11/04/2007.
Wethersfield: Calls drop on I-91 southbound at Exit 26 on 08/04/2006.
Last occurred on 01/07/2007.
Glastonbury: When traveling south on CT-17, the area near
JCT CT-66 to CT-151 to CT-149 to CT-82 has such poor coverage that a given
call cannot be maintained for any significant period of time. Similar
drops occur when using Nextel, but Verizon is generally better (but it too
needs
work there). Most recent instance occurred on 03/20/2006.
Middletown: Drops occur on CT-9 while traveling southbound directly at
the traffic light with CT-66 (which is under the Portland Bridge) on
08/04/2006. Most recent instance occurred on 01/07/2007.
Haddam: While driving on CT-9, coverage begins to drop approximately a
mile and a half north of Exit 7 and will drop upon arrival at Exit 7
going both northbound and southbound. Coming from the south may be
different, in that calls start degrading at Exit 7 and subsequently drop a
mile and a half north of it. Most recent instance occurred on 08/24/2007.
Westbrook: Coverage problems arise while driving approximately 70mph
either northbound or southbound directions on I-95, slightly west of Old
Saybrook and about a mile and a half or two miles north of Exit 65 near
"F-troop" (CT troop F) and also near the JCT with CT-153. While calls do not
drop, audio dropouts so severe will occur in this area that neither party
can hear the other for a period of approximately thirty seconds. Most recent
instance occurred on 06/17/2007.
Madison: Calls drop at the Hammonsett connector between US-1 and I-95
on 08/04/2006. The drops happen at the "turtle", which is a piece of rock
which sticks out on the southbound side that has been painted like a turtle.
Most recent instance occurred on 06/17/2007.
Hamden: Calls drop on the Merritt Parkway while driving either north or
southbound. The audio path experiences a disruption at some point around
Mile Marker 49 and calls drop shortly thereafter. Most recent instance
occurred on 05/25/2007.
Hamden: Calls drop on the Merritt Parkway while driving either north or
southbound. The audio path experiences a disruption at some point around
Mile Marker 49 and calls drop shortly thereafter. However, it has been
observed that only the call's audio will go silent while passing through the
tunnel at Mile Marker 49 when traveling at 65mph. Most recent drop occurred
on 05/25/2007. Most recent audio silence occurred on 03/25/2008.
Beacon Falls: Drops occur while driving on CT-8 approximately one mile
north of Exit 24. Most recent instance occurred on 02/27/2008.
Roxbury: Drops occur while traveling on CT-67 approximately two miles
north of the JCT of CT-172 and approximately one mile north of Woodbury town
line. Calls initiated while on CT-67 at the JCT of CT-172 will deteriorate
while approaching the Woodbury town line. They will subsequently drop
altogether approximately a mile north of there. Most recent instance
occurred on 10/17/2007.
Westport: Drops occur on I-95 between Exits 17 and 18 (which is the
Sherwood Island Beach Access Road). Most recent instance occurred on
01/12/2007.
Norwalk: Calls drop on the Merritt Parkway between Exit 40 (which is for
Norwalk) and Exit 42 (which is for Westport/Redding). Throughout that
stretch, there are downlink audio dropouts preventing the mobile phone from
hearing the called/calling party. Most recent instance occurred on
05/10/2007.
New Canaan: Calls drop on the Merritt Parkway between Mile Marker 15 and
Mile Marker 14, which is slightly north of the New Canaan rest stop. Most
recent instance occurred on 04/08/2008.
Greenwich: Drops occur on the Merritt Parkway/CT-15 at Exit
29 in Greenwich. Initial drop occurred on 02/02/2005. Most recently occurred
on 01/07/2007.
New York
NYC - Manhattan - While traveling west on 79th St. through Central Park
between Central Park East and Central Park West, calls drop midway through
the transverse. Last observed on 02/16/2007.
NYC - Manhattan - Drops occur while walking eastbound on 68th St. Calls
initiated before 3rd Ave and 68th St begin to degrade while approaching 2nd
Ave. While transitioning from 2nd Ave to 1st Ave, calls drop for no reason.
Most recent
instance occurred on 07/03/2007.
NYC - Manhattan - Drops occur on Park Ave. as the street winds around
the Met Life (Pan Am) building. Coverage is generally good in the tunnel
under Park Ave. directly south of the Met Life building, but calls
drop when traveling around the building itself. Most recent instance
occurred on 10/23/2006.
NYC - Manhattan - Calls drop on Irving Place while driving north or
southbound between 14th St. and 15th St. Most recent instance occurred on
06/28/2007.
NYC - Manhattan - Drops occur on 1st Ave while heading north between
11th and 12th Streets. Calls which, after having been initiated only a
few blocks to the south (5th St., for example), are clear and
distortion-free rapidly degrade approaching 11th St., and will drop
between 12th and 13th Sts. Last observed: 07/01/2007.
NYC - Queens - While traveling westbound from Queens County towards
New York County (Manhattan) on the Queensboro Bridge about 70% of calls
with Cingular GSM tend to drop at the center point of the bridge crossing
over Roosevelt Island. Ironically while entering the bridge, there's a
billboard saying "Cingular Wireless- the fewest dropped calls". Last
observed on 07/05/2007.
NYC - Queens - While traveling west on the Long Island Railroad (LIRR)
from Woodside into Penn Station, the main line tracks (ie, not the Port
Washington tracks) go under a small tunnel/overpass, which also facilitates
the crossing of other rail tracks. While passing through that small
enclosure, GSM coverage frequently drops. However, there is no tunnel to
pass under while traveling on the eastbound side on the main four tracks and
thus calls do not drop there. This is in the vicinity of Sunnyside Yards.
Most recent instance occurred on 08/06/2007.
NYC - Queens - There is no coverage in terminal 9 at JFK International
Airport at the lower level/arrivals area inside of the building in the
vicinity of the baggage claim area. As this is a place where cell phones are
frequently used, and as all other carriers appear to work quite well there,
it is surprising that Cingular would not have adequately covered that area
at this point.
NYC - Queens - Calls drop while driving west and transitioning from the Long
Island Expressway (I-495), passing under the ramp for the LIE to enter I-278
West. Most recent instance occurred on 11/06/2007.
NYC - Bronx - Signal is very weak on the Bronx River Parkway between
Exit 8 and Exit 10, starting near Southern Blvd. This continues past Exit 9
and up to Exit 10, where calls subsequently drop in the vicinity of the
Bronx Zoo. As calls cannot be placed or received, the phone is effectively
rendered useless. After Exit 10 comes the county line for Westchester
County. Please see the Westchester section of this list (below) for
adjoining drops on the Bronx River Parkway in Westchester County. Most
recent instance occurred on 07/16/2007.
Dutchess County: Calls initiated on NY-82 traveling northbound using the
Cingular network (phone indicates "Cingular") will degrade and eventually
drop at a point between CTY-89 and Tompkins Rd. Subsequent to the drop, the
service switches from Cingular to Dobson Cellular. Most recent instance
occurred 07/03/2007.
Dutchess County: Handoff failures occur while traveling either eastbound
or westbound on I-84 between the JCT with the Taconic Parkway at Mile Marker
52 and the rest area located at Mile Marker 55. Calls initiated using
Cingular and traveling west on I-84 will hold while driving up the hill and
heading towards the police barracks and the rest area, but will drop while
coming down the hill. The phone will then display Dobson PCS. However, if
the call is initiated on Dobson in Poughkeepsie and driving west on I-84, it
will hold while passing the rest area and going up the hill, but
subsequently drop while going back down the hill. The phone will display
Cingular. Most recent instance occurred on 07/03/2007.
Dutchess County, LaGrange - While driving either north or south on the
Taconic State Parkway, calls suffer poor quality and tend to drop on the
former Dobson Cellular network within a one mile radius of the JCT with
NY-82. Most recent instance occurred on 10/21/2007.
Dutchess County, LaGrange - Drops occur on the former Dobson Cellular
network while heading either east or west on NY-82 while crossing under the
Taconic Parkway. Most recent instance occurred on 10/21/2007.
Dutchess County, Fishkill: Drops occur when traveling either northbound
or southbound on US-9 approximately two miles south of the JCT with
Smithtown Rd. Most recent instance occurred on 10/04/2007.
Dutchess County, East Fishkill - Calls on the former Dobson Cellular
network drop while traveling in either direction on NY-82 between the JCT's
of the Taconic Parkway and CTY-21. Most recent instance occurred on
10/21/2007.
Putnam County, Putnam Valley: Calls drop on the Taconic Parkway between
Mile Markers 22.1 and 22.3, which is about half a mile south of the JCT with
Bryant Pond Rd. (this drop appears to be part of a series of drops on the
Taconic State Parkway from five miles north of the Hawthorn interchange all
the way up to I-84, where the ex-Dobson Cellular would begin coverage). Most
recent instance occurred on 03/31/2008.
Putnam County, Peekskill Hollow: Drops occur on the Taconic Parkway at
Mile Marker 23.5 (this drop appears to be part of a series of drops on the
Taconic State Parkway from five miles north of the Hawthorn interchange all
the way up to I-84, where Dobson Cellular begins coverage). Most recent
instance occurred on 09/13/2007.
Putnam County: Drops occur on the Taconic Parkway at the JCT of Knapp
Rd. at Mile Marker 34, which is approximately one mile south of Miller Hill
Rd. Most recent instance occurred on 06/18/2007.
Putnam County, Mahopac: Drops occur at Mile Marker 30 on the Taconic
Parkway (this drop appears to be part of a series of drops on the Taconic
State Parkway from five miles north of the Hawthorn interchange all the way
up to I-84, where Dobson Cellular begins coverage). Most recent instance
occurred on 09/13/2007.
Putnam County, Mahopac: Calls drop on the Taconic Parkway at Mile Marker
28.1 (this drop appears to be part of a series of drops on the Taconic State
Parkway from five miles north of the Hawthorn interchange all the way up to
I-84, where Dobson Cellular begins coverage). Most recent instance occurred
on 09/13/2007.
Putnam County, Carmel: Drops occur on the Taconic Parkway upon reaching
Mile Marker 27.2 (this drop appears to be part of a series of drops on the
Taconic State Parkway from five miles north of the Hawthorn interchange all
the way up to I-84, where Dobson Cellular begins coverage). Most recent
instance occurred on 09/13/2007.
Putnam County, Carmel: Calls drop at Mile Marker 25 on the Taconic
Parkway (this drop appears to be part of a series of drops on the Taconic
State Parkway from five miles north of the Hawthorn interchange all the way
up to I-84, where Dobson Cellular begins coverage). Most recent instance
occurred on 09/13/2007.
Orange County, Woodbury- Calls drop while driving both north and south
on NY-32 (near where NY-17 heads off from I-87/the New York State Thruway)
about two miles north of the Woodbury Commons Shopping Center (which is
located at the approximate junctions of NY-17, US-6 and NY-32). Most recent
instance 11/11/2007.
Westchester County, Shrub Oak: While driving on the Taconic State
Parkway, calls drop at Mile Marker 18.5 at the JCT with NY-132 and US-6

where Dobson Cellular begins coverage). Most recent instance occurred on
10/04/2007.
Westchester County, Ossining: Calls drop approximately five miles north
of the Hawthorn interchange on the Taconic Parkway at Mile Marker 10.3,
which is Pinebridge Road (this drop appears to be part of a series of drops
on the Taconic State Parkway from five miles north of the Hawthorn
interchange all the way up to I-84, where Dobson Cellular begins coverage).
Most recent instance occurred on 09/13/2007.
Westchester County, Hutchinson (Merritt) Parkway around Purchase, NY,
near the CT border: Calls which are initiated near the JCT of the Hutchinson
River Parkway, I-287 and I-684, in the general area of Purchase, attenuate
while approaching the CT border and drop shortly after passing the Greenwich
rest stop on the Merritt Parkway. Last occurred on 03/26/2007.
Westchester County, Cortland: Drops occur on US-9 at the JCT with NY-9A.
Most recent instance occurred on 07/16/2007.
Westchester County, White Plains: Drops occur just south of the North
White Plains train station. The connection is stable at the Valhalla station
which precedes the North White Plains station when traveling south. Just
south of the Valhalla station calls quickly attenuate and drop. Most recent
instance occurred on 11/27/2006.
Westchester County, Scarsdale: Near the Metro North/Scarsdale station on
the Harlem Division, the uplink connection will tend to mute, especially
traveling north after leaving the station. The connection is not dropped,
the uplink (and perhaps the downlink as well) appears to go mute. Most
recently observed on 11/14/2006.
Westchester County, Hawthorne: Calls drop while traveling north on the
Sprain Brook Parkway at approximately Mile Marker 11.6 upon reaching the
Sprain Brook's JCT with NY-100, just south of the Hawthorne interchange.
Last occurred on 09/13/2007.

19 (which is Mamaroneck Blvd). Most recent instance occurred on 01/24/2008.
Westchester County, Yonkers: Calls drop from the Bronx/Westchester
County line up to the Cross County Parkway. The signal becomes very weak and
calls cannot be placed or received. Most recent instance occurred on
07/16/2007. Please see the Bronx section of this list (above) for adjoining
drops on the Bronx River Parkway in Bronx County.
Nassau County, Glen Cove: Drops occur about half a mile south of the JCT
of NY-107 and Glen St. Most recent instance occurred on 12/17/2007.
Nassau County/South Oyster Bay: Calls initiated in the area of the JCT
of NY-25A and NY-106 will drop while proceeding southbound on NY-106 towards
Hicksville, approximately halfway between NY-25A and NY-25. Call slowly
degrade and then drop upon arriving at the traffic light just north of
NY-25. Last occurred: 10/15/2006.
New Jersey
Perth-Amboy area: Drops occur while traveling north on I-287 near the
JCT with the New Jersey Turnpike. Drops also occur more generally
when traveling both north and south on I-287 between US-9 and the NJTP.
Most recent instance occurred on 11/07/2006.

drop completely. Most recent instance occurred on 05/14/2007.
Chadds Ford Township: Calls drop while traveling either northbound or
southbound on US-1 at the JCT with Independence Way, approximately five
miles south of the JCT with US-202. Most recent instanced occurred on

MD-155: Drops occur between the JCT of MD-156 and MD-161 (which is near
Havre de Grace). Most recent instance occurred on 06/01/2007.
White Marsh: Cingular gives a fast busy signal while traveling between
Mile Markers 72 and 65 on I-95. This is two miles north of the Baltimore
Beltway (I-695). This has only been witnessed occasionally and as of yet it
cannot be consistently reproduced, but it is a problem if one wants to place
calls around there. Last occurred on 06/28/2005.
Towson: Calls tend to suddenly drop after exiting the Baltimore
Beltway/I-695 heading north and merging on to I-83. Most recent instance
occurred on 07/21/2006. (On 10/11/2007, a call placed from I-70 on the inner

Corrected Problems

corrected and/or no longer suffer from regular/repeated drops:
Massachusetts
- Natick: Calls drop on I-90/Mass Pike near the Natick exit. Generally,
while traveling east, calls attenuate on the slight incline prior to the

ramp for Natick, GSM calls will drop. Most recent instance occurred on
