Voicestream Quietly Releases GPRS In The U.S.

    The problem with GPRS is that the suppliers are likely to kill the market by charging too much and restricting the accessable sevices to a few WAP sites which the supplier has a relationship with (I'm told at least one telco in the UK does this, but I havn't checked it out).

    SMS used to be a service that was hardly ever used due to expensive prices and a restriction to the suppliers network, alot of people didn't even know their phones could do it. As soon as the prices dropped and the telcos opened gateways to each other, the volumes exploded, now SMS' are a large part of the telcos' income.

      This is both a real and a serious problem. The problem is that the ISPs couldn't get it in their heads that people will use all the resources they can, i.e. hog as much bandwidth as they can. Why shouldn't they? The problem as I see it, is that the ISPs want to go in late and try to "fix" the problem, only causing even more problems. The phone companies are not quite as fresh when it comes to these things, hence the per unit charge.
      As I suggested in my original post, I would prefer a payment plan for a QoS (Quality of Service). In other words, I buy a bandwidth. Let's say I buy 256kbit/s. If the system doesn't use the capacity, I will get the full speed, but if a user with 1Mbit/s needs the bandwidth, I have to live with my 256kbit/s.

    Hi everybody!
    I just have to say one thing:
    Here in Europe GPRS is already in use in cellular networks so I have some experience with it (the experience comes also from my job, I work at the largest cellular network provider here in Austria). Unlike HSCSD, GPRS does not provide stable data tranfer rates. 170 k sounds cool, but as experience has shown, these rates only apply if you stand directly next to a receiver. HSCSD uses multiple channels, reaches about 43 k and if you loose a channel (e.g. when the network gets crowded) you pay for one channel less. GPRS uses slots in one channel, and if a slot is unavailable - well, bad luck. Here in Austria most people prefer HSCSD for it is cheaper and more reliable, the maximum transmission speed reached with GRPS in real use is only slightly higher than HSCSD and generally speaking -> HSCSD is most times faster. GRPS is not a solution for high speed date. It is only a small step towards UMTS.

CDMA IS-95 does. You can run a CDMA network and an AMPS network at 800MHz.

  22. Speed is not the problem by Cato · · Score: 2

    The problem with WAP is incompatibility/bugginess, low usability and lack of useful content - speed is barely faster using GPRS, which simply makes it more convenient by being always-on. Every time I try a new WAP site, it doesn't work on my phone (a Nokia 7110, supposedly a standard one), due to WAP gateway, WAP browser or site problems. I would actually use WAP a bit if it worked, despite the usability - some of the content is becoming useful, e.g. a site that tells you driving directions from any point in the UK.

  23. Re:GSM s.i.m.s do lock you in by Cato · · Score: 2

    Yes, this is known as SIM locking in the UK, and does happen. Some operators sell you SIM locked phones and charge a fee for unlocking, others do not. In practice, many people dump the phone and service after a year and get a new one - this is often cheaper than getting an upgrade phone. However, for people who do stay with one operator, it is generally possible to transfer the SIM - it's just a matter of checking you are not SIM locked, or paying the fee if you are.

  24. It's the availability, stupid by kr4jb · · Score: 3, Insightful

    The main appeal for GPRS is not the high data rates. In practice, the data rates are similar to single-slot CSD, or sometimes as good as multi-slot HSCSD. It depends on how the operators provision their RF channels. The big deal about GPRS is that it is packet switched, "always on", and has no long call setup times.

    These features make casual web/wap browsing more appealing than the old way (dial up, wait, connect, read web page, pay while reading, hang up).

    There are two main uses for cellular data connections: (1) apps in the phone, like email and wap (2) use as a modem, connected to a laptop. GPRS will make #1 a lot better. The effect it will have on #2 will be that you pay for bits and not time (which is good for activities like web browsing, which have download-and-read usage patterns).

    It's a shame that the cellular infrastructure companies (see my email address) have marketed GPRS as a "high bandwidth" solution instead of an "always on" one. The carriers are just selling what they've been told.
