I do this on my G1 with pandora quite often.

Just as a point of fact - I do this over edge. The signal is pretty consistent around my area so I rarely end up with a pause.

Yiannis, a lot of people here are just joking around based on your qualification "high speed". The only issue you would have is the 3G cell network handoff/switching. That's why they say you need a big buffer, so that your stream keeps playing while the download is interrupted.

The Doppler comment was one such joke. The effect for audio wouldn't apply as you are traveling at the same speed as the source. The bit about the car behind you getting it is just a joke, as well. Even a Prius can't violate the relevant laws of physics.


So does T-mobile's 'unlimited' plan have a 5GB cap? and am I right to assume that internet radio does not require much bandwidth.

Actually they can and occasionally, do :-) Fortunately we have protocols like TCP to sort it out.

No you would be wrong. Lets take a low quality stream of say 24kbps not altogether awful with AAC.

24*60 = 1440K
1440*60 = 86400K

So for an hours listening time at low quality we are talking 86400/1024 = 84MB an hour.

Most streams are closer to 64Kbps and some even 128. So those numbers can ramp up fast.

As bug 4128 is still open, the buffer may still be of fixed (byte) size in the Maemo 5 media player. Therefore, the number of seconds buffered will vary depending upon the bitrate of the Internet radio stream playing.

Vote it up.

For as low as $6.99, you can get yourself a subscription to Serius radio and save yourself the troubles of dropped services.

It doesn't have station from 5000 miles away...

The OP's question is a good one - 3G and 4G signals are notoriously difficult to transceive while one endpoint is in motion relative to the second.

Doppler effects at highway speed can shift the 3G/4G carrier by hundreds of Hz. Multipath interactions overwhelm the signal. Speed of tower handoff becomes a significant issue.

Has anyone been able to test the N900's ability to maintain a HSPA stream at 100km/h or more?

This shouldn't be such an issue with 4G (LTE), whose "shorter frame size supports higher throughputs at moderate to high vehicle speeds".

Done.
