How limited can it be when they offer an unlimited plan and MobiTV?
Verizon is pushing V-Cast and if it becomes even mildly popular,
Cingular will have to beef up their network to compete. Why would
streaming video and audio directly to a phone be OK, but some basic web
surfing from a laptop not be OK? Greed! They just want to be able to
keep charging the "special needs" groups more. $20 seems like a fair
price for cellular dialup-like service. More than that? No way.
$14.95 DSL seemed absolutely absurd just a few years ago, but it's here
now (and offered by Cingular's parent SBC, no less.)
These new "terms" are interesting. I'm just not sure if this is
another example of harsh TOS verbage that's only going to be exercised
in certain abuse circumstances (like the "no-servers" policy in most
AUPs that is virtually always ignored). Are they really going to deny
themselves $20/month from paying customers that suck up 30mb per month
on a laptop, pissing them off, potentially losing them entirely to
another carrier? Or are they just shielding themselves from true
abuse? Or maybe they'll create a "walled garden" for MEdia Net
logins. Just seems like that would be going backwards in a time when
Verizon is going to be kicking them in the pants with their better
mobile broadband network (that might actually be WORTH more than $19 a
month).

Re: No more "tethering" on Cingular MEdia Net
EDGE is faster than GPRS but not truely high speed yet. It only operates
at 70 to 137 Kbps. That is kilo BITS per second. Divide that by 10 to
get kilo Bytes per second that means 7 to 14 KBps. Not fast enough for
streaming video. What we are waiting for is UMTS which runs at 2Mbps or
over 10x that of edge.
Lets take a look at why any celular company would discourage tethering.
A voice call takes up about 8 to 16Kbps while a single tether connection
can use up to 2000Kbps. Therefore for every tether connection they can
not take 125 phone calls. This will increase congestion at the towers.
How many 2MB sessions could a tower handle before it's banwidth is
exceeded? Wouldnt that cause an increase in cost due to more towers
being built and/or the data pipe to each tower to be widened? The
cellular system is designed to handle phones with WAP access. It is not
designed to handle hundreds of high bit rate connections. If you think
there is no difference between tethering and wap brousing, can you
download and store Giga bytes of data from a file sharing network on to
your handset? You sure can to a tethered PC. If you want to use huge
amounts of data, it has to be paid for somehow. A wap browser uses a
lot less data than a tethered computer.

EGPRS(EDGE) actually operates at 100-150 Kbps, depending on device Class, in
good signal conditions. Class 4 operates at the low end of that range. Class
10 operates at the high end of that range.

Actually 18+ KBps (Bytes) with a Class 10 device.

It is in fast enough for low-quality streaming video, which can be done even
over ISDN, which is slower than EGPRS(EDGE).

UMTS, which is already deployed in some areas, actually runs at typical
downlink speeds of 220-320 Kbps.
What we're really waiting for is HSDPA, an upgrade to UMTS with roughly double
the speed and lower latency, expected to be available in 15-20 markets by the
end of the year. Then we'll be waiting for HSDPA devices.

A voice call actually uses 1 of 8 timeslots on a channel for the entire
duration of the call.
A data connection uses 1-4 of 8 timeslots, but only when data is actually
being transferred.
In addition, the network can be programmed to limit the number of available
data timeslots, particularly when load is high.
>This will increase congestion at the towers.
There is no real contention between voice and data, only between data and
data; i.e., not wanting one heavy use subscriber to interfere with another
subscribers, much like a heavy downloader on cable Internet .

It's actually designed to handle both voice and data. How much is simply a
matter of capacity.
