As you know T39 and R520 support the HSCSD service. I would like to know if they support timeslots of 9.6 kb/s (which means up to 28.8 kb/s), or they also support 14,4 (up to 43,2). As far as i know, Nokia does suport 43,2.

Both R520 and T39 support to 28.8kbps on HSCSD mode

As far as I know they both have 28,8 kBit/s download and 14,4 kBit/s upload speed.

Actually both Ericsson handsets and Nokia handsets support 14,4 KB timeslots. The difference is that Ericsson can use three slots at one time, while Nokia can use 4. Therefore Nokia can obtain 43.2 KB(14.4 times three) down and 14.4 up.

Ericsson supports 28.8 down and 14.4 up. R520 and T39 does however support 56.6 KB GPRS, while Nokia only supports 33.6 KB with it's 8310.

can someone clue me in on this hscsd stuff?

HSCSD Stands for High Speed Circuit Switched Data, and basicly means it combines several data slots to gain speed. It's kind of like you do with ISDN when you use both lines. You get 128KB speed instad of 64KB, but you pay double the price since you're using two lines to connect.

You also have to decide how to use the slots you pay for, in regards to uploading/downloading. You have to have at least one slot down and one slot up, since that is what a normal mobile data connection gives you. After that, depending a little on the company, you pay for each extra slot, and can decide to use it for uploading or downloading. All of this is decided through the driver on your PC/HPC before you dial up.

You can in theory get insanly high speeds this way, but the cost both to the consumer and telehpone comany is high, and therefore there's usually a roof of about 40-50KB to connect this way.

so what's the diff between GPRS and HSCSD ? Which is better? They are both forms of WAP? I know that the 6210 support HSCSD.

With HSCSD the phone, takes exclusively the timeslots, but with GPRS you share them.

Posted by: Knut.G.

Aye, but there are a few other differences. GPRS is an always on connection, so you only pay for the amount of data you send/recieve. HSCSD is basicly a bunch of normal dialup connections bundled together for speed, so you pay for the amount of time you're connected instead.

They're not only for WAP, but for any connection to the internet where you can use your laptop, PC or HPC also.

GPRS will allow a lot of exciting features for GSM phones, since it allows for push services. For example, you can go to a wap site, and it will send data that you subscribe to to the phone. For example, a football match that you want to know the progress of, would pop up in the wap window as things happen. A lot cheaper than SMS.

When using Vodafone D2 or E-Plus here in Germany HSCSD is much cheaper than GPRS. You don't have to pay for each extra slot. For up to 4 bundled download channels of 14.4 kbit/sec each you pay the same like for a normal 1 channel data call. Given that and the fact that the volume prices of GPRS are extremly high here HSCSD is much cheaper.
In fact it's also much faster than GPRS most of the time because you have all the bandwidth for yourself when using HSCSD.

But only the Siemens S40 can bundle 4 download channels - you get only 1 upload channel than = 4+1. You can also do a 3+2 channel configuration with the S40.

The Nokia 6210 and Cardphone 2 are supporting at least 3+1 and 2+2 channel configurations.

But the Ericsson T39 and R520 are supporting only a lame 2+1 though there are rumors that a future software upgrade could change that for the better.

And as for GPRS:
the Ericssons are supporting currently only 3+1 slots of 13.4 kbits/sec each (including software R2M) and not the 4+1 slots which were advertized. Again a future software upgrade will fix this according to Ericsson.

Here in Greece, is the same. You can use up to 4 timeslots (Cosmote offers 6 timeslots) without paying nothing extra (only the sudscription to Data).

As far as the GPRS, Telestet has a monthly fee of 14,67 Euros and unlimited Downloand (temporalily), and Vodafon-Helllas 10 Euros monthly fee (with 1 MB free) and 0.005 Euros per extra kb.

Of course... it all means jack to subscribers in the US until the carrier inplements it.

It's Panafon -Vodafone yet, but Panafon with very small letter and Voda very big. I beleive in the early 2002 it will be Voda hellas.
