AT&T’s brewing HSUPA-gate: the inside story

Though it really came to a head with the recently-launched Inspire 4G, users have noticed that there really aren’t many phones in AT&T’s stable that deliver stellar upload speeds — the Atrix 4G is suffering the same sub-megabit performance, as are older devices that should seemingly support HSUPA like the Samsung Captivate.

We’ve chatted in the past few days with a source who offers an interesting explanation: AT&T currently requires that all handsets that it sells “handshake” with the network as 3GPP Release 5 devices, the last official set of 3G specifications that lacked support for HSUPA. That feature — also known as EDCH, or FDD Enhanced Uplink — was added in Release 6. Though AT&T is apparently working on permitting the bulk of its handsets to handshake Release 6, presently only the iPhone 4 (and presumably all of its recent data devices like USB modems, which may also use Release 7) are allowed. Neither we, nor our source, know why this is. Our source believes that the Release 6 certification may happen within a “month or two,” which would explain why some AT&T sales reps in live HSPA+ areas are telling customers that the “4G network” isn’t live yet.

You can form your own conclusions as to why AT&T might be imposing this arbitrary limitation, but we do know that “enhanced” backhaul figures prominently into the company’s 4G story; there may be concerns that flipping on HSUPA for everyone right now would overwhelm its legacy infrastructure. At any rate, it sounds like this could all be solved soon through a combination of network changes and possibly firmware updates for individual devices, so let’s keep our fingers crossed.

Samsung Galaxy S 4G now available from T-Mobile

Samsung’s Galaxy S 4G might not have the very latest version of Android or too much hardware differentiation from the original T-Mobile Vibrant, but hey, it brings a front-facing camera and HSPA+ connectivity, so of course it costs $200. T-Mobile will have disappointed many with its clarification that the Galaxy S 4G will cost a pair of Benjamins on contract, exactly as much as its Samsung-built predecessor did seven months ago, and not as the carrier had originally indicated, $150. Also similar is the fact that T-Mo is launching this phone with an Android build that’s one iteration behind the cutting edge, meaning the Froyo update headaches of last autumn may return in the form of Gingerbread jitters this spring. All the same, if the Magenta team sees fit to chop the Galaxy S 4G’s price the same way it’s been doing with its other Android handsets, we could be in for a fine bargain in the near future.

[Thanks, Matt]

Motorola Atrix 4G gets the teardown treatment, fourth G nowhere to be found

If our review of the Atrix left you hungering for more, you can now feast your eyes on the guts of Motorola’s new Android powerhouse. Thanks to the folks at iFixit, its teardown reveals a familiar range of parts — 16GB of NAND flash, 960×540 PenTile LCD, 1GB DDR2 RAM and that beast of a NVIDIA Tegra 2 CPU. What’s more, is that the teardown brings to light some enticing news — the glass panel is not glued to the LCD. This allows for the clumsy to not have to spend the extra dough if they crack the glass (which is usually affixed to the display). Hit the source link if you’ve got your Atrix and are ready to dismantle the thing yourself.

P.S. — There is a Qualcomm MDM6200 HSPA+ chip inside the phone. The title is meant to be a joke in reference to misconceptions about 4G wireless technology. You can read about them here.

US Air Force raises concerns over LightSquared’s LTE network messing with GPS

Following a navigation system’s instructions without driving into a ravine is hard enough as it is — can you even imagine how hard it’d be if you kept losing GPS reception every time you drove within range of an LTE tower? There have been a few anecdotal concerns raised over the last several weeks that LightSquared’s proposed LTE network — which would repurpose L-band spectrum formerly used for satellite — is too close to the spectrum used by the Global Positioning System, leading to unintentional jamming when the towers overpower the much weaker GPS signals. Things have gotten a little more interesting, though, now that the US Air Force Space Command has officially piped in. General William Shelton has gone on record saying that “a leading GPS receiver manufacturer just … has concluded that within 3 to 5 miles on the ground and within about 12 miles in the air GPS is jammed by those towers,” calling the situation “unbelievable” and saying he’s “hopeful the FCC does the right thing.”

Presumably, the USAF thinks that “the right thing” would involve pulling LightSquared’s license, but for its part, the company says it believes Shelton is referring to a test conducted by Garmin (possibly explaining that recent outage in the Southeastern US?) using simulated interference filters — not the actual filters that it has spent several million dollars developing and perfecting. Regardless of how effective the filters might be, the idea that the only thing standing between a functional GPS system and a constellation of space-borne paperweights is a private company’s privately-developed, privately-operated filtering equipment… but then again, we love LTE. Decisions!

[Thanks, Brian]

Netgear unveils a pair of 42Mbps HSPA+ routers, and one for LTE

We’re not sure how they feel in lands where fiber optic connections flow like wine, but in most of the developed world a up to 42 megabit per second internet connection feels mighty fine. Fine enough, in fact, that it can make sense to share it with your peers, and that’s why Netgear’s new MBR1310 and MBR2000 routers are here. They’re quad-band DC-HSPA+ units that dole out that precious 3G data over 802.11n WiFi or via four 10/100 wired ethernet ports, with the MBR2000 adding ADSL2+ for a wired backup option. If you’re lucky enough to be working with LTE in Europe, there’s the MBR1517 as well, virtually identical to the model announced for Verizon but presumably with different carrier support. No word on when, where, or how much any of these fallback connectivity options will cost. PR after the break.

Audi starts calling its vehicular broadband plans ‘Audi connect,’ partners with Alcatel for LTE internet

Audi’s had grand designs on the connected car for years now, and is presently looking to upgrade to LTE, but first it’s time to address the most important consideration — marketing the stuff effectively. To that end, Audi’s unifying its infotainment initiatives under the brand Audi Connect, so it will be absolutely clear how you can pimp your ride with tech when you walk into an Audi dealership. That is, if you don’t already have Audi Connect, because the company claims it’s already present in the A8, A7 and A6. Those three automobiles can presently add an optional UMTS modem for online apps, though Audi’s also working with Alcatel-Lucent to bring faster LTE connectivity by 2014. Expect a software update sooner than that: this summer, Audi hopes to add live traffic data and voice commands to control a suite of Google services as well. Find more details at our source links.

Sony Ericsson CTO: first LTE device coming ‘pretty soon,’ also considering Android tablets

Back in late 2008, Ericsson boldly predicted that 2012 will be the year of LTE; and fast forward to today, one year shy of the big one-two, said company’s joint venture with Sony is already teasing its first LTE device. In a recent interview with Fierce Wireless, Sony Ericsson CTO Jan Uddenfeldt talked about SE’s renewed focus on the US market, and how its relationship with Google helped securing its first-ever deal with Verizon. While emphasizing that SE’s been in the CDMA business for years in Japan, Uddenfeldt also referred to the TD-LTE demonstration with ST-Ericsson and China Mobile at MWC, which featured a prototype LTE device developed by his own gang. Looks like SE’s all set to enter the game, but the question is when will we see its first LTE device on the market? Uddenfeldt said “pretty soon,” and he further fuels speculation by mentioning a potential collaboration with Sony on some Android tablets (maybe the S1?). Oh, such a teaser this man is.

Update: Swapped in an image of the prototype looking a bit too much like a 2007 UMPC above.

Motorola’s Sanjay Jha on Xoom: ‘Our ability to deliver 4G justifies the $799 price point’

Motorola’s Xoom will cost a tad more than the competition, but company co-CEO Sanjay Jha has an explanation for why that might be: he told reporters that the Android Honeycomb tablet’s price is justified by the promise of speedy 4G internet. Of course, the $800 Xoom doesn’t actually come with 4G connectivity out of the gate, but Jha told reporters that the Xoom’s LTE upgrade will be free, and that wonder of wonders, the tablet will be capable of pulling down 50 megabit per second speeds. Someone might want to check Sanjay’s math — sure, in the midst of a Verizon fog at CES 2011, we were able to manage 33Mbps, but we typically get less than half that speed on a day-to-day basis.

LightSquared says it has signed up five companies for its wholesale LTE service

LightSquared has faced something of an uphill battle in getting its wholesale 4G LTE network off the ground — even including accusations that it’s a threat to national security — but it looks like it’s having fairly good luck attracting some customers. According to Chief Marketing Officer Frank Boulben, LightSquared has signed agreements with five companies so far, including two carriers, one website, a national retailer, and a device manufacturer — none of which it’s able to name, of course. Boulben also revealed that the company, which plans to compete with the likes of Verizon, AT&T and Clearwire, is finished raising money for the “short term,” and that it plans to begin trials later this year in Las Vegas, Baltimore, Denver and Phoenix once it finishes its lab testing in Dallas.

Sprint evaluating switch to LTE over the next four to six months

Sprint has had an on again / off again relationship with LTE for some time now, but it looks it may finally be nearing a commitment one way or the other. Speaking in a roundtable discussion at Mobile World Congress this week, Sprint’s Senior Vice President of Networks, Bob Azzi, said that the carrier would be studying the rate at which its customers migrate from EV-DO to mobile WiMAX over the next four to six months, and that it would evaluate the best way to use its existing spectrum before it reaches a firm decision on a possible switch to LTE. As we’ve heard previously, that switch would be a fairly straightforward one from a technical standpoint due to the carrier’s recent upgrades to its network, which allow it to upgrade its gear to LTE simply by swapping in a new baseband card and issuing a software patch.
