Bullshit..
This must be bullshit.
Ericsson has mobile phones with Bluetooth all ready. -
Re:Structural languages are not used because....
Haskell has CGI and animation libraries, as well as a system for writing music. There are foreign library interfaces and highly optimizing compilers, database interfaces and graph visualizers.
Libraries and Tools in Haskell
Haskell in Practice
Here are some books and papers about how to program in Haskell and functional languages in general.
I particularly recommend Hudak's book; Paul himself is a very clear teacher and lecturer, as is Zhong Shao, who does research in ML (Standard ML of NJ). I think SML is the only functional language around whose semantics are completely specified.
Follow these links and learn about Erlang (in massive production use at Ericsson), high level abstraction through functions defined via structural induction over datatypes, monads, layered functionality used to build parsers (via parser combinators), and a type theory for object-oriented programming. -
no conspiracy, just engineering trade-offsI work for a mobile phone company, so I've had to learn all of the in's and out's of the modern cellular protocols. This is my (somewhat technical) take on it.
The public land mobile network (PLMN) was developed for LAND use, and a few assumptions were made in the process. Making the system available for a few (airborne) customers would simply make it less efficient for the rest. As with all engineering, the designs involve several trade-offs. The entire system was designed around keeping the mobile terminals cheap and mass-producable, so everyone can buy a cheap phone and use it 99% of the time. We do not have unlimited hardware budgets, and we are not trying to make the phones universally usable (under water, tunnels, on planes, at sea, etc).
The GSM standard assumes that the mobile station is moving at less than about 300 miles per hour. At higher speeds, the doppler shift becomes very significant. You do the math. This becomes a very hard (expensive) spatial geometry problem to solve for a simple 8-bit processor in a phone (that is already loaded down with a lot of protocol tasks).
The standards also assume that you're near the ground level. Sure, when you transmit, you'll light up several cells from a plane (typical PCS-band cell radius on the order of a mile or two, with a maximum radius of 22 miles). Likewise, you're hearing several base stations at once. Again, a hard problem to solve.

Ericsson Wap Tools
I just wanted to point out that Ericsson also has tools like this avalible. I don't know how they compair, but they can be found here. http://www.ericsson.com/developerzone

Re:Nice...
You can get som more info about the mp3player here and see what it looks like.

Re:Seen it before.
Just in case anyone got interested, before you dive into the muddy hell that is www.ericsson.se, here's a quick link to a tiny picture of the MP3 player accessory for the T18. To complete that, here's a link to some information about the device itself. Don't expect any hard info (such as memory capacity, battery life, price, or availability) though...

EPOC : but that's two devices..
You could use an EPOC PDA : they have good email and web browsing apps - but you'd need a data capable mobile phone to go with it..
I'd go for either the Ericsson MC218
or
The Psion revo
oh yeah, and there's more revo info here.
For the phone, something like a Nokia 7100 Series or 8200 Series would do.
There's currently an HTML browser for the psion devices, with a WML one promised. The MC218 already has a WML browser.

Great for Symbian!ARM is what Epoc, Symbian's OS runs on. Considering that Ericsson, Nokia, Motorola, Psion and Matsushita (Panasonic) owns Symbian and will use its operating system in palmtop computers with built in phones, handhelds and smartphones the future looks extremely bright!
Oh, forgot. Sony is also an Epoc licensee - and they make cool devices!
Go ARM!

I'm surprised no-one's mentioned the Ericsson T28!
I bought a T28 about 3 months ago (as soon as they were available in New Zealand). It does almost everything you could ever want in a phone, it even has Tetris & solitaire for those who like games, & voice dialing which I find very ahndy when I'm feeling lazy.
.. it weighs about 80-90 grams. I forget I have it in my pocket. It gets my vote. -

What CNet said about cell phones in japan isnt really new. Email/Short Message Service is available worldwide, so is voicemail (though not locally on the phone), and voice recognition/dialing, and special ringtones etc etc can all be found in most GSM cell phones made by Nokia and Ericsson. Whats new are the i-mode phones by NTT DoCoMo. These have 256 color vdeo capable displays and other neat features.

Re:What the heck is a Bluetooth?Well, those old URL:s weren't too useful... =)
But there's much new stuff. This Intel page explains a lot of the history behind Bluetooth.
Basically, (the Intel page doesn't say this) some engineers at Ericsson thought about designing a new protocol for communication between their (Ericsson's) devices in 1994, and started developing it. The project wasn't initially called Bluetooth, but "MC link" (MC = Multi-Communicator). But somewhere during the development, they started to realize that the chips needed for this would be much cheaper if it was a widely adopted standard, so they started talking with their arch rival Nokia about sharing the technology and making it a common standard. They formed a Special Interest Group (SIG) in 1998, together with some other well-known companies (amongst others IBM, Intel, Motorola, 3Com, Casio, Cirrus Logic, TDK, Compaq, Dell, Xircom, Lucent, Toshiba, Psion, Qualcomm and Axis).
Last year they released the specification for version 1.0 of the standard. And experimental Bluetooth devices have been built using the standard and shown on various expos last year, and real devices are under development now. I think we'll see many of these devices released this year. That's the brief history of Bluetooth.Here is also Ericsson's Bluetooth site. Here's the specs.

Re:Its a TOOL. Not only for corporations
> MAKE YOURSELF HEARD
Watch out, this slogan is already taken :) -
WinCE compatability, why?WinCE is more than dead (it's called Pocket PC now, right?) - PalmOS and Symbian OS (Epoc) is the way to make this attractive.
Palm has a huge momentum in the US, and in Europe there's no doubt that Symbian will rule the smartphone and handheld market completely. Looking at their website they have special made versions of the OS for many screen sizes and devices. It's only a question of _when_ those things will appear on the market. To get a brief hint on what's to come, look at how many awars the Psion Revo has won!
It will be very interesting to see an OS not really made to work on small devices compete in this arena. WinCE failed badly - PalmOS is doing quite well even though it's hardly a real OS, and the Symbian OS has been tailor made by first Psion and now Symbian since many many years for exactly this
...Yeah, I have devices with WinCE, PalmOS and the Symbian OS
;) The MC218 (by Ericsson) is the one I use for my daily work ... -
Maybe this?Well, I don't know about *CPU*, but I think they might have something in mind along the lines of what Ericsson, Nokia, Intel and Sony is creating, the "Bluetooth" specification. The cutting edge in net development right now is in mobile communication, and the centre of that is in Scandinavia. Many Transmeta developers come from Scandinavia...
I have tried to make Slashdot post links to interesting articles about the advancement of mobile communications several times, but since it isn't made in the US, it seems they just don't get it.
The bluetooth homepage, and a recent article in respected magazine The Economist which talks a bit about Bluetooth. Ericsson just gave out a press release about the first real Bluetooth product, a pretty cool toy. Now you can pretend you are the agents in the Matrix...just move your hand to your ear and mutter something whenever you want to call. And this thing doesn't even have wires like they do in the movies!
I am hoping that whatever Transmeta is doing wont be a direct competitor to Bluetooth, and that the two technologies can coexist. It feels great that my country is finally world leading in technology! :-)
********
Offtopic: I'm a bit pissed at how Slashdot treats non-American news. I asked them if they would consider adding topics for -Europe -Asia -World. They said that no, since non-Americans are in a minority, the news about that have to be extra interesting or the American readers will be bored. Ok, but a Slashdot poll showed that over 1/3 of the Slashdot readership is European, and they have added topics about real minority subjects like VA, LinuxCare, Compaq and Amiga without hesitation before. Note that there is also a "United States" topic, even though 99% of the location specific news posted is about that anyway. Whenever their is a legal question, the topic is "The department of Justice", and American institution. Whenever their is a constitutional issue (as when they mentioned net censorship in Australia) the topic is "We the People" with a picture of the American declaration of independence...
Taken together, it gives me the feeling that the Slashdot leadership thinks that America is the standard by which all things are measured, and the American part of the audience is the only important one.
Oh well, I'll stop bitching now. Have to go study.

Re:Comments...
Um, people don't have to "trash their existing phone system[s]" just to use something with DECT. Most DECT devices I've seen (standard home cordless phones, such as these beauties) use DECT internally, while connecting to your existing home analog phone system in the base station end only.

Really fast cellular data tranmission
Ericsson is first with a new device using a new protocol enabling data transmissions at 112 KBps over existing GSM networks. It's called GPRS, and it's currently being implemented by a German operator called T-Mobil. There's more info at www.gprsworld.com.
