DoCoMo To Use Linux On Their 3G phones

ilbrec writes "Looks like NTT DoCoMo will be using Linux on their 3G phones next year. This actually was reported yesterday in Japan (here), but I could not find any article in English until now. While it's not clear who will be making the Linux phone for them, I would certainly be interested in seeing them once they are out. No word on this anywhere at DoCoMo's website at all, however." Reader paku adds links to similar coverage in Forbes and in Japan Today.

    DoCoMo does not intend to force them to use the Linux-based software and it does not preclude the use of other operating systems including Smartphone software from Microsoft Corp as future OS candidates for its 3G phones, the source said.

      The engineers decided on Linux, but the PHBs don't want to take risks (correctly, by the way.) So they, in their usual manner, tell us something while telling us nothing, and not committing to anything.

      But seriously, Linux is great on embedded systems. I am right now working with Arcom's PC/104 board that has XScale CPU on it. I left the board plugged in for several months, and when I checked it was still working fine :-) It's Debian, btw, and takes only 8 MB Flash (other 8 MB are free, and I have larger CompactFlash plugged in as /dev/hda for development).

    Manufacturers are expected to comply with DoCoMo's request to replace their systems with a unified Linux standard apparently for fear of being left out in the cold

    Now, is this a good reason to move to Linux? I mean, if this is the reason for small manufacturers to move, had DoCoMo chosen Windows, they would probably have moved to that instead. Oh well.

      To comply with the GPL, they need to make source code available. But it's perfectly possible (and legal, IMHO IANAL) to embed the OS in ROM in such a way that it can't easily be changed. Source code availability is still useful, though: It helps developers of apps understand how the system works, makes security audits possible and means that once the device is no longer produced, it'll be easier to make an emulator.

      The downside for the phone makers is that their competitors can also take the source code and use it in their phones, but that's the price they pay for using any pre-existing software (free or not) rather than developing something from scratch. The phone makers are better off standardizing on Linux than Windows (no MS tax), and so are DoCoMo and its customers.

      Except that Symbian is controlled by Nokia. And the Symbian dev tools are sucky. You have to use their wacky C++ variant, incompatible with all your legacy code. They don't even have a remote debugger to debug programs running on the phone! Borland sells a Symbian remote debugger, but you have to pay extra, you have to switch to Borland's C++ compiler, and it barely works.

      From the user's perspective, they can't tell the difference (given a decent GUI). Using Linux underneath a user-friendly GUI is an advantage to the phone manufacturer.

  7. Will there ever be a standard? by SexyKellyOsbourne · · Score: 4, Insightful

    We all know Microsoft is trying to be the "standard" for cell-phone operating systems much in the way that they took over almost the entire desktop and workplace market, but will there ever be a Linux standard? I know Symbian is also trying to create a standard for cell phones that already is quite strong in Europe, but there really should be a consortium where Linux developers can get together and set standards, instead of them being scattered across the internet proposing a few ideas.

    If there's going to be standards, they should always be open source and free as in beer. Corporate control of standards only creates monopolies. Even in America, a lot of people are dropping their landlines for cellphones, and if there's ever a Linux standard for it, it should be created quickly before it's too late.

    Many handset vendors are working with Linux in some way, and some vendors like Motorola are working with all kinds of O/S from Linux through to Symbian and MS.

    But does the O/S really matter if all the phones support Java now anyway? If you're going to write software for open mobile deployment, wouldn't you be inclined to consider Java first since it alone is ubiquitous on phones? O/S generally doesn't count for much in that decision.

    More than that, consider the data formats... Those indespensible new compelling 3G services if they ever eventuate will be all about selling and consuming data. Whose format(s) are service vendors going to use and support and work with? The content is what will be monetized with consumers and the format is what determines the nature of the franchises, like e.g. Office on the desktop.

    Whether the data format is something proprietary like .ppt or .doc or .swf or something open like SVG or XHTML I think is more significant to mobile developers' careers than the O/S.
