Excuse me for offtopic: I wonder why there is no 3G in Berlin? This looks quite weird.

Don't be so sure. I've met competent engineers who have very weird issues with their M2M equipment being suddenly unreachable on the network without the modem reporting any error status.
Sierra, Cinterion, Wavecom and others have a well-established market, and their products do ve...
This is also not neccessarily for us to see. I think it's an interesting and relevant parallell track. There's no reason *not* to do it when it is *easier* than the other things we want to do, is my reasoning somehow.

Also not neccessarily the only market we have. By now it's easy to customize your smartphone with tons of apps and so on, but regular users also like to change technology to fit them now and then. OK, it could be argued that they fall under the definition of free software enthusiasts, but the people I think of usually don't.
And such users are interested in real telephones, notin modems for embedded systems.
Maybe they have laptops and would like to use open source internet connectivity as well. In Berlin there's e.g. never 3G service available anyway, so 2G-only may be fine.
Just because it's not for me or you doesn't mean that noone else will not want it. :)

Hi Alexander,

it depends on the Operator and where you are. They all only use 2100 MHz for 3G, not the lower 900/1800 MHz bands (which they could do legally after a EU regulation). But yes, indoor coverage can be really bad. For example in my apartment it is difficult to have 3G of all operators, and the one I use mostly (Eplus) barely has 2G coverage here. T-mobile and Vodafone are generally better.
It's of course different if you're at major locations like train stations or the big squares downtown...
Another note: I've recently seen some operator predictions for Germany, and they assume something like GSM being in operation until 2020 - definitely significantly longer than the life time of their existing GSM licenses (expiring in 2016). This tells us a lot about the installed/deployed user base, as well as the limited 3/3.5/4G coverage..

Harald -
Some operators have told us that they expect to continue GSM/EDGE service for another 10-15 years, especially in rural areas. At Range, we borrow a line from King James Bible, "GSM will be with us always, even unto the ends of the Earth."
UMTS is designed to deliver high data rates over fairly short distances and has poor power-efficiency characteristics for both the Node B and the UE. LTE is a step further in that direction. As long as that trend continues, which it will because that's where the money is, 2.xG systems will have no cost-effective replacements in areas with low subscriber density.

Sorry - I was unclear. There are networks, but there is not nearly enough capacity for all users. This isn't neccessarily because of inadequate infrastructure, it may just be the best we can do with the shared medium at the cost of what the market is prepared to pay.
When a Berlin friend visited Sweden his 3G USB modem LED was suddenly shining with a color he had never seen before.
