Siemens Continues OFDM Push
Khoo writes "German telecommunications gear maker Siemens is backing a new kind of broadband wireless technology that will compete with Wi-Fi and 3G cellular services." As we covered recently, speed tests have been up to 360 Mbps and one of the latest rumours is that they will use it in conjunction with VoIP servers. That's unconfirmed, but particularly for new phone deployments, laying no wire would be nice. And Yes, Virginia - ITMJ is part of OSTG, like Slashdot.
First post again mother freakers.
ITMJ, part of OSTG reports about OFDM to use VoIP?
Good...

Nothing says "unprofessional job" like wrinkles in your duct tape.
Is new technology for wireless broadband transfer necessary? The 802.11 Wi-Fi standard is still being continually improved, and I can't think of any applications in which either 3G or Wi-Fi aren't the most ideal data transfer... things.
Of course GSM was digital, YTF couldn't they route those 52 byte voice packets over UDP or something ?. Maybe aggregate them into 1500 byte blocks and push over ethernet or the equivalent with ATM ?.
VoIP works , but I don't see the point for mobiles to run a full IP stack. (oh, yeah I work on a phone with an IP stack and it drains the battery like HELL when in packet services mode).
Quidquid latine dictum sit, altum videtur
let's hear it for the t4c
without adding the old ones too is very confusing and frustrating to users.
Very few Seimens phones I have seen have bluetooth.
Bluetooth has become the MAIN function I use my Sony Ericcson T616 for now - even above and beyond talking on the phone.
I can control my iTunes, PowerPoint, RadioShark, ElGato TV, DVD, and just about any other program. What's even better is I can search for songs and view the song detail right on the phone + control the mouse on screen.
Also with 802.11g which is backwards compatible with b - users will have to have this new standard to even operate - so lines or no lines - it's still confined.

One thing seemilngly always omitted in these 'speed' stories is distance. While a 3x speed increase over 11n - which is 2x better than 11g - is impressive, if the basic assumption that the speeds correlate over the same distance is incorrect, the speed is not all that great. It would take multiple repeater modules to make up for the shortage, limiting its usefulness.

Its always good to know that we are researching more ways to radiate our heads in favor of greater profit margins for big business. Soon we will all wear lead lined caps and clothes and the truth about the increase risk of cancer and other health issues will become more apparent. Then we can all sue telco companies (and big business) for health reasons which will in the long term affect corporate profit..
Its always good to have a bright outlook on corporate life..
GNAA declares victory over Wikipedia
Zeikfried - Associated Press, Nigeria
In a week which shall be recorded in Wikipedia infamy (and then vandalized and redirected to clitoris), the oft persecuted and never defeated internet missionaries of the Gay Nigger Association of America struck yet another powerful and telling blow against the powerful forces of bigotry and racism. Most notably, the growing zionist community on renowned internet pissing yard wikipedia.org.
And the records have indeed tumbled, with an unheard of third successful survival from the digital shitheap that is "Votes For Deletion". Coming in spite a heinous act of self promotion and cyber terrorism by Pat Gunn/Improv (formerly known as Aharon Meshenstein prior to his infiltration of the United States), who listed and inspired mob vandalism upon the GNAA's entry.
Fresh from his promotion of Wikipedia's $50,000 fundraiser for arms and supplies to the Jewish state of Israel, Improv launched a series of unprovoked and slanderous attacks against the well loved organisations leadership, all the while using foul and unholy necromancies to enlist the dead themselves to vote the entries deletion. Names such as "Wolfman" and "Demonslave" only adding to the damning list of evidence linking Mr Gunn to the occult.
Though Improv's actions gained him a small majority, a shock last minute intervention from Pope John Paul II spared the pages untimely fate, although as yet unconfirmed reports have indicated that several hundred 8-year old negro children were driven to the Basilica to secure the pontiffs support. Others point towards the black curse cast upon the deletion campaign by the support of infamous Brawl Hall mouthpiece "Yoyo" as the main driving force behind the salvation of the aforementioned entry.
But the details are likely to cause few sleepless nights among the group, only one of whom was willing to speak to the press. Namely GNAA Wikipedia contributor Popeye, who interrupted his drawing of pornography to give a brief dismissal the controversy: "Even with Improv's shady dealings, the sheer size and girth of a swollen GNAA phallus enables it both an identity and a vote of it's own. Making such discussion moot".

Check out this performance graph compared to various broadband and wireless technologies... It's really, really fast, and seems stable as well.
Did they use the new cover sheet for the TPS reports?
Trust me on this one, kids.
So I can buy a $$$$ device which supports 3G, and run a VoIP app on it so that I can ... talk, wirelessly, to anyone in the world? Wow... what an excellent invention!!!
I want to delete my account but Slashdot doesn't allow it.
From the CNET article... "[Flash-OFDM] offers connection rates of 1.5 megabits per second." So the 360Mbps is in the lab, and is not likely to be out of the lab and into your pants (these are cell phones) for several more years. 1.5 Mbps isn't too bad for now though.
Slashdot... news and commentary on par with CBS.
Okay, I've been spending too much time cleaning up my music collection today. I could have sworn for a moment that the topic was "Siemens Continues KMFDM Push"! Imagine my shock...
For your security, this post has been encrypted with ROT-13, twice.
I don't see why OFDM is getting treated like some new tech holy grail. 802.11a and g both use it, and have for a very long time.
My sig is blank, I typed this by hand.

How is this technology practical? Good luck getting licenses in any industrialized nation!

You can barely make a voice connection on them and the unexpected billing charges will double your bill, and they want to sell picture phones? They're smoking dope.
They press never criticizes its big advertisers, maybe the AARP will kick up a fuss.
I agree. OFDM isn't some sort of holy grail. It doesn't do anything that somehow invalidate's Shannon's Law for channel capacity, and it is quite possible to come within 0.5 dB of Shannon capacity with other modulation schemes. It's nothing special, just another method for modulation that happens to have certain benefits in some situations. (Examples include higher multipath immunity.) The European DVB-T (Terrestrial Digital Video Broadcast) standard uses OFDM and it's been around for a while (at least five years I think.) As the parent said, 802.11a and g use OFDM also.
OFDM is not a magic bullet. It's also not new.
Yes, Siemens' 360 Mbps number is impressive, but to achieve that performance, they either used some very interesting tricks (OFDM not being the key here, possibly a MIMO multiple-antenna system, a technology that is still under heavy research.), or made tradeoffs (high bandwidth or high SNR requirements) that will make the system useless for real-world deployment.
retrorocket.o not found, launch anyway?
More at nextelbroadband.com. It's currently only available in the Raleigh/Durham/Chapel Hill/RTP, NC area. Too bad I live in Florida now.
Well hmm... sun, warm weather and hurricanes *or* cold, snow, ice and Nextel broadband. I think I'll stay.
While the appeal of high-speed internet access over a phone is nifty to consider, exactly how much could you get out of it with those tiny screens?
"What I cary in this box is your utter subjugation."
Every corporation is pushing his own thing. Microsoft is pushing this, IBM pushing that, Sun pushing other. and now Siemens. This is the end of the world.
