NTT DoCoMo had a pretty lavish setup here at CTIA, though no new product caught our eye. However, they did have the results from the Super 3G / LTE shenanigans they've been up to in Japan, and the results show serious speed. They're touting Super 3G / LTE as 3.9G -- wow, that extra .4G seems to be making a huge diff -- with theoretical downlink and uplink speeds listed as 70Mbps and 300Mbps. Compared to current HSPA speeds this is a monstrous leap, can you say kiss your cable goodbye? Hit the gallery below for more pics.

Just think -- this time next year, we'll all look back at this milestone and wonder how on Earth we thought it was impressive. For now, however, we wouldn't blame you for high-fiving everyone around, as NTT DoCoMo has stretched the boundaries again with a recent Super 3G field test. Reportedly, the outfit was able to record "a downlink transmission rate of 250Mbps over a high-speed wireless network in an outdoor test of an experimental Super 3G system," and while it's not quite the 300Mbps we'd heard about before, you won't find us kvetching. If all goes to plan, the firm is hoping to "complete development of the technologies required for the eventual launch of a Super 3G network" by 2009, but who knows how long we Americans will have to wait to indulge after that.

Remember that Super 3G network you tried to forget about after realizing it'd likely never leave Japan? Yeah, well NTT DoCoMo and Fujitsu were busy showcasing a prototype base station that supports the specification at CEATEC. Reportedly, the device "marked a download rate as high as 900Mbps" when utilizing MIMO. Sadly, there was no mention of this technology (nor the base station) going commercial anytime soon, but we'll take every demonstration we can get in the meanwhile.

It looks like any hopes that the 4G intellectual property landscape would be a little less of a Qualcomm-controlled minefield are fading fast. Thanks in part to recent acquisitions, a senior vice president pointed out in a recent interview with IDG that the company now owns over 1,000 patents pertaining to OFDM, OFDMA, and MIMO -- technologies which'll prove crucial to 4G data, regardless of the standard(s) that ultimately win out. In other words, whether the networks of tomorrow are banging LTE, UMB, or some flavor of WiMax, Qualcomm's confident that it's in a position to cash in, just as it's doing now. Sorry, Nokia.

After some recent testing, Nokia Siemens Networks (NSN) is on the verge making Virtual Multiple Input Multiple Output (MIMO) the transmission protocol for Long-Term Evolution (LTE) networks. Translation: the wireless networking company is going to be squeezing more data bits into existing allocated spectrum -- which is sure to please heavy-use data customers (and moreso to carriers). The NSN team used SDMA (Space Division Multiple Access) techniques to link two separate mobile devices with a base station simultaneously -- and on the same radio channel. Technically, that is quite a feat since radio communication becomes directional and quite efficient, unlike traditional cellular networks. Using current GSM or CDMA systems, wireless customers and towers broadcast in a 360-degree pattern -- but not so with SDMA technology. NSN's results included data uplinking at 108 megabits per second. That is a data rate we can get excited about -- and so should carriers needing to use existing spectrum more efficiently. Seeing as NSN just opened its doors a month ago, this is quite an impressive announcement, no?

As America struggles with the transition to proper 3G networks, Japan continues to make strides towards the fourth generation of mobile phone networks. In field experiments, NTT DoCoMo, the largest mobile phone operator in Japan, achieved an approximate 5Gbps downlink data rate. That beats previous tests by a factor of two, as DoCoMo managed to achieve 2.5Gbps over a year ago in December 2005. The increase in data rates appeared to be as simple as doubling the number of antennas -- the MIMO technology in use takes advantage of multiple antennas capable of transmitting signals independently: more antennas = more data -- and using a proprietary solution for receiving the signal. So, what are the prospects of the Japanese public getting their hands on a wireless standard that can download up to 640MB per second? Not great, for the moment at least. DoCoMo is planning on releasing its specific findings regarding the technology at 3GSM in Spain: when they do, we'll know more. Until then, just try and keep the drool off the keyboard, ya hear?

As usual, we're given virtually no time to revel in the high-speed (relatively speaking, of course) wireless data we do have before some eggheads have to go and throw the wet blanket on us. Researchers from Germany's Heinrich-Hertz-Institut (a division of Fraunhofer) have apparently taken some standard-issue UMTS equipment and modified it to use MIMO -- the same tech employed in many modern WiFi devices -- to achieve 100Mbps downstream and a full 50Mbps upstream. For the sake of comparison, UMB (aka EV-DO rev. C) takes the crown with 280Mbps down; while there's no word on when this MIMO stuff might hit the streets, UMB won't see the light of day until 2009 at the earliest, so our German friends have a little time to capitalize. And yes, we'll be just fine with a mere 100Mbps on our cellphones, thankyouverymuch.
