NTT DoCoMo's CTIA 2008 booth tour, hello Super 3G
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.%Gallery-19778%
Super 3G hits 250Mbps downlink in NTT DoCoMo field test
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.
Buffalo's WHR-HP-G54DD AirStation router comes loaded with DD-WRT
Buffalo's out tooting its own horn today, as the AirStation Wireless-G MIMO Performance Router claims to be the "first commercial wireless router to come with DD-WRT firmware pre-installed." Aimed squarely at the SMB and SOHO market, the WHR-HP-G54DD (WHR-HP-G54 pictured) is the first device to emerge from the firm's partnership with NewMedia-NET. Of note, this device features five QoS levels to prioritize traffic, optimized link state routing (OLSR), a data transfer application with VPN functionality, PPTP protocol support, WMM and DDNS, and a bevy of management applications including remote network status logging, remote web management via HTTPS and web-based backup / restore. If all this sounds like your cup of tea, you can pick one up now for £41.70 ($86), and you can check out the full (and we mean full) list of specifications right there in the read link.
NTT DoCoMo, Fujitsu show off Super 3G base station
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.
Airspan intros Mobile WiMAX Wave 2 USB device
It's been some time since Airspan kicked out a new device enabling laptop (or desktop, for that matter) users to hop on the Mobile WiMAX highway, but that's changing thanks to its recently-unveiled MiMAX USB. This USB 2.0 dongle "turns any laptop into a high performance Mobile WiMAX client," and it marks the first product in the Mobile WiMAX MIMO family. As with the 16eUSB that came before it, this gizmo allows users to connect to "virtually every Mobile WiMAX network that is deployed worldwide," and supports "all of the target Wave 2 MIMO Mobile WiMAX certification profiles (2.3GHz, 2.5GHz, 3.3 - 3.8GHz, and 4.9 - 5.8GHz)." Furthermore, the MiMAX USB even plays nice with licensed and unlicensed frequencies, and if you're looking to detect WiMAX networks before flipping on your machine, the optional MiMAX Finder should do the trick. Sadly, there's no mention of a price just yet, but we've got a feeling those details could be loosed during next week's WiMAX World USA in Chicago.
Amigo's R622AG WiFi router mirrors Xbox 360 design
We're fairly sure Amigo Technology's R622AG WiFi router meant no harm when it came out of the laboratory looking exactly like Microsoft's latest console, but we'll be surprised if no legal teams are contacted over this one. The four-port router supports 802.11a/b/g, includes a pair of USB 2.0 connectors for sharing external data or printers over the network (shown after the jump), and should look like a long lost twin situated beside your Xbox 360. No word yet on price nor availability, but this thing definitely outdoes the other 360 copycat we saw just days ago in terms of closest resemblance.
Atheros offers up 802.11n Draft 2.0-spec XSPAN solutions
You'll probably recall Atheros' name from the rundown of Draft 2.0 802.11n gear mentioned just a week ago, but now the firm is getting official with its bundle of refreshed pre-N gear. The new AR9001 family of chipset solutions builds upon the existing XSPAN offerings, and is reportedly compliant with the latest IEEE draft of 802.11n. Primarily aiming for SMB and Enterprise markets, the outfit is doling out a number of AR9001AP access points / router SoCs that "integrate its 802.11n MAC / baseband and 400MHz Wireless Network Processor (WNPU) into a single chip." On the consumer front, the AR9001U sect presents the "world's first dual-band capable 802.11n USB chipset," and also includes the company's first 1x2 MIMO configuration. Unsurprisingly, pricing details on all these goodies are still up in the air, but Atheros claims that second-generation AR9001 items are currently sampling to customers and should hit " full volume production" in Q3 of this year.[Via PCWorld]
Qualcomm: we're flush with 4G patents
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.[Via mocoNews]
Nokia Siemens pumps virtual MIMO networking
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?
IEEE pushing 802.16m WiMAX to 1Gbps, hopes to converge with 4G
If there's one thing that we'll never be satisfied with, it's finding out just how many nanoseconds we can shave off our download times from year to year, and thankfully, the IEEE seems to get that. While it has certainly taken its sweet time with 802.11n, the task force has already voted to make 100G the next Ethernet speed, and now it's pushing to make WiMAX implementations even quicker. Reportedly announced at 3GSM, the IEEE has began working on a new version of the 802.16 standard, dubbed 802.16m, which "could push data transfer speeds up to 1Gbps while maintaining backwards compatibility with existing WiMAX radios." Potentially more interesting than cheering for speed boosts is the group's outright assurance that this protocol will meet the ITU's requirements for 4G, insinuating that it should be the token choice for further 4G developments. Nevertheless, the increased bandwidth is supposedly needed due to convergence between VoIP and various forms of multimedia (IPTV, streaming video, digital downloads, etc.), and however true that may be, some skeptics are still understandably doubting the whole "backwards compatibility" aspect. Still, the IEEE hopes to have this together by "the end of 2009," but considering the team's less-than-stellar track record in the deadline department, we're not holding our collective breath.[Via DailyWireless]
NTT DoCoMo achieves 5Gbps downlink in 4G field trials
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?
Macworld goes in-depth on the new AirPort Extreme
Dan Frakes at Macworld has published an in-depth article that delves into just what the new AirPort Extreme is all about. Pointing out some of the details we covered in our original post, Dan goes the full mile and then some with a history of the device and explanations of some interesting new features. Most notably, he unfolds fancy new technology like the multiple-input-multiple-output (MIMO) feature of 802.11n, as well as a new time-based access control system which lets you specify times that each device can access the internet. Are your kids (or your roommate?) spending too much time on MySpace when they should be doing homework on their MacBook? No sweat - just use Apple's easy-breezy AirPort Utility to cut 'em off until... well, whenever you feel like it.Dan also covers what's missing - things like Gigabit ethernet (which, given the fact that it's been in Macs for years, still blows my mind) and the once-standard antenna port. He even pulls an industry price check to make sure Apple isn't taking us for too much of a ride with the new station's $179 price. All in all it's a good state-of-the-AirPort-Extreme for anyone interested in this recent sleeper release from Apple.
Horizon partners with Navini to spread WiMAX across Northeast US
Following up on Sprint's announcement to spread the WiMAX love to Chicago and Washington, D.C., Horizon is looking to broaden that area of coverage out just a bit by partnering with Navini Networks. This news comes after the FCC approved Horizon's purchase of the WCS A Block spectrum previously owned by the diminishing Verizon, and now the firm is looking to deploy the wireless goods in "Boston, New York, Philadelphia, Washington D.C., Baltimore, Pittsburgh, Buffalo, Richmond, and Cincinnati" for starters. Horizon has selected Navini's 802.16e equipment to get things up and running, and states that its objective it to "provide wireless last mile access to residential, business, and emergency restoration markets," but folks in rural areas will seemingly get shunned for now. Horizon isn't wasting any time getting this thing started, either, as it plans to start building the network in Q1 of this year, with hopes for "ongoing expansion and additional network deployments in the latter part of 2007."[Via TheWirelessReport]
SMC ships trio of draft-spec 802.11n networking gear
It looks the barrage of draft-spec 802.11n gear being released isn't slowing down anytime soon, and helping the yet-to-be-ratified protocol gain more ground is SMC. Making good on its promise to ship draft-N gear, the networking company has reportedly launched the Barricade N, which utilizes "multi-antenna MIMO support" to connect at rates of "up to 300Mbps," sports a four-port Ethernet switch, and can automatically prioritize duties such as music / video streaming to keep things skip-free. Complementing the new router are pre-N versions of the company's EZ Connect CardBus and PCI wireless adapters, which will give your lappie or desktop the ability to take advantage of the ultra-speedy 802.11n standard. All three devices are purportedly available right now, with the Barricade N selling for $120, the PCMCIA adapter demanding $80, and the PCI card costing $90.
Researchers show 100Mbps cellular data
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.
Intel shows off WiMAX Connection 2300 chipset
Intel has had some decent success with its "kitchen sink" approach to WiFi ubiquity and integrated graphics dominance, and it doesn't look like they're taking any chances with WiMAX. Hardly more than a month after busting out its first WiFi-integrated WiMAX Connection chipset, the 2250, Intel is testing out a new 2300 version which supports mobile WiMAX and MIMO functionality. The the new all-in-one chip also claims lower power requirements and less heat generation than its predecessor, making adoption of the newly improved chips a relatively painless one. The whole shebang is still managed by the same unified software, and Intel is supporting "over-the-air provisioning" to allow for easy configuration and consumer activation of services, as opposed to the traditional service provider-based way of doing things. Hard to tell how that PR-speak will end up playing out for actual consumers, but it at least sounds promising. With the design finalized, Intel still has some more testing to do, but hopes to start busting this thing out in card and module forms in late 2007.[Via Laptoping]
Qualcomm swallows Airgo, announces first 802.11n Draft 2.0 chipset
As we edge ever closer (right?) to finally seeing a finalized 802.11n protocol, companies are shoving (sometimes in secret) draft-spec 802.11n kit into their products to take advantage of the here and now. Taking yet another baby step towards the goal, Qualcomm is releasing a fourth-generation chipset, dubbed the AGN400, to take advantage of Draft 2.0 of the IEEE 802.11n standard. The chipset itself was crafted by Airgo, who just so happened to be acquired by dear Qualcomm in one fell swoop, and also features Airgo's True MIMO Gen-N technology. Although Airgo has had its quibbles with backwards compatibility in the past, this device will supposedly play nice with all previous 802.11s, including the earlier draft of 802.11n and the typical trio of 802.11a/b/g. Reportedly ready to fit a "full array" of interface buses for OEM products, this Draft 2.0-compliant chipset purportedly provides "significantly better performance, a greater feature set, and enhanced interoperability" over the previous rendition. While pricing details weren't discussed, it should be ready for the world to see by CES, while True MIMO Gen-N products should be available by "the first quarter of 2007."[Via PhoneMag]
Corega brings its ugly stick to 802.11n party
Nothing much to see here, just Corega doing its thing with a no-frills 802.11n router and PC card. The CG-WLBARGE router and CG-WLCB144GE card both sport XSPAN technology for multiplex usage of the MIMO antennas, resulting in some fancy "3x3 communication," which sounds no different than what you'll be getting from any other recent 802.11n offering. What is lacking is that fancy guarantee ASUS has for its new draft-n products, meaning late-in-the-game IEEE revisions could render your setup obsolete in a few months. But with looks like these, that wouldn't necessarily be a bad thing.[Via Akihabara]
ZyXEL jumps into the Draft-n game with new MIMO router
Most of the big names have already busted out their own MIMO Draft-802.11n routers, but that doesn't mean there isn't plenty of room for the minor players to give Draft-n a shot, and ZyXEL's new NBG-415N Wireless Broadband Router sounds like a decent offering from the Taiwan-based company. They're claiming speeds of up to 300mbps for the $160 unit, and they've got some "StreamEngine" tech from Ubicom to prioritize certain types of data. The router also packs a USB port for WCN connectivity of printers, media players and the like. We should be seeing this one near the end of the month, along with laptop (PCMCIA) and desktop (PCI) versions: the NWD-170N and NWD-370N which go for $100 and $120 respectively.
Hawking's Wireless-108G MIMO for Macs
While rumors of a MIMO or otherwise high-speed networking tech to replace Apple's aging Airport Express wireless networking products have been bandied about, actual products still do a bit more to actually boost networking speeds. Hawking Technology's new Hi-Gain Wireless-108G aims to do just that, though from the looks of it they don't offer a compatible 108G wireless card to take full advantage of the speed boost. The router is rather equipped to get the most out of a multi-user 54G network by boosting range up to 3x, stabilising connections and penetrating dead zones. Of course, most MIMO routers claim a similar collection of enhancements, and Hawking's compatible Hi-Gain range-boosting adapters are merely 54G, but it might be just the bump your network needs until those Airport ExpressErer products come along.
