LightSquared and former FCC chief engineer say GPS tests were rigged

LightSquared and former FCC chief engineer Edmond Thomas on Wednesday said the GPS test devices that were used by the National Space-Based Positioning, Navigation and Timing Executive Committee (PNT EXCOM) to test its new network were rigged by “manufacturers of GPS receivers and government end users to produce bogus results.” The company said that devices from GPS manufacturers, which have claimed LightSquared’s network interferes with GPS communications, were “cherry picked” in secret and that independent authorities were not allowed to partake or oversee the tests or test results. In addition, LightSquared said the tests focused on obsolete technology that is only used in “niche market devices” and that are “least able to withstand potential interference” from wireless networks.

Torture tests show iPad 2 glass much stronger than original iPad [video]

Torture tests show iPad 2 glass much stronger than original iPad [video]

Despite being 27% thinner, a series of stress tests show that the glass covering Apple’s iPad 2 display is significantly stronger and more flexible than the glass used on the original iPad. The team at Apple product repair shop iFixYouri took it upon themselves to put glass display covers from the original iPad and the iPad 2 through a series of abusive stress tests, and the results are pretty remarkable. We’ve already spoiled the ending but watching the iPad 2 glass survive these torture tests is pretty impressive to say the least. Hit the break for the video and please, don’t try this at home.

Apple calls foul on web browser speed test

Apple calls foul on web browser speed test

Earlier today, we told you about a study conducted by Blaze Software comparing the native browser speeds in Apple’s iOS and Google’s Android. The results of over 45,000 tests were published, and the firm concluded that Android was roughly 52% faster than iOS in terms of browser performance. Not so fast, says Apple. In a statement to blog The Loop, an Apple spokesperson pointed out a perceived flaw in Blaze Software’s methodology. “Their testing is flawed because they didn’t actually test the Safari web browser on the iPhone,” wrote Apple’s spokesperson. “Instead they only tested their own proprietary app which uses an embedded web viewer that doesn’t take advantage of Safari’s web performance optimizations. Despite this fundamental testing flaw, they still only found an average of a second difference in loading web pages.” The UIWebView framework, which was used to run Blaze’s “proprietary app” in an “embedded web viewer,” does not leverage Apple’s Nitro JavaScript engine — the part of mobile Safari that Apple claims is nearly 2x faster than its predecessor. Tests that leverage the enhanced JavaScript engine would, according to Apple, have improved Safari’s performance. Blaze Software has yet to publicly comment on Apple’s rebuttal. More →

Motorola ATRIX 4G vs. LG Optimus 2X: Not all dual-cores are created equal

Motorola ATRIX 4G vs. LG Optimus 2X: Not all dual-cores are created equal

Android enthusiast blog Android and Me oversaw a benchmark battle royale on Friday. While the goal of the exercise was to pit the ATRIX 4G against the LG Optimus 2X to see which phone makes better use of its dual-core Tegra 2 processor, the overall results help emphasize something we constantly stress here on BGR: specs are only half the story. The blog arranged a benchmark battle between the ATRIX 4G and Optimus 2X along with Google’s Nexus S and Nexus One, HTC’s G2 and Motorola’s DROID, and the results are hardly what you might expect. First things first — LG’s Optimus 2X handily topped the list in six of eight tests performed, bested only by the ATRIX in the Smartbench 2011 productivity test and the Linpack test. The 800MHz-packing G2 outdid several 1GHz offerings in numerous tests, however, which may come a s surprise to many. Hit the break for a few sets of benchmark results mapped out on graphs, then hit the read link to check out the rest.

Motorola ‘wireless tablet with embedded WLAN’ hits FCC; Wi-Fi only XOOM?

Motorola ‘wireless tablet with embedded WLAN’ hits FCC; Wi-Fi only XOOM?

Not really digging the $800 price-tag set to be placed on the 3G Motorola XOOM tablet? Help may be on the way. A recent filing shows that the FCC is testing a “wireless tablet with embedded WLAN” manufactured by Motorola. Now, there’s no way to know exactly what this is… but our money is on a Wi-Fi only XOOM. The tablet in question, being referred to as the IHDP56LU1 in documentation, is only having its Bluetooth and Wi-Fi a/b/g/n chipsets tested — there was no mention of a cellular radio anywhere. Hopefully, with wireless carriers out of the picture, Moto can get a little more agressive with the pricing. More →

Are these Verizon Wireless LTE speeds?

By on September 30, 2010 at 9:40 AM.

Are these Verizon Wireless LTE speeds?

Is this a screen shot of speeds achieved on Verizon’s 4G, LTE network? If you’re to believe a poster in the dslreport.com forums, then yes. The speeds, almost 13 Mbps down and 4.4 Mbps up, are reportedly from someone testing Verizon’s LTE network in Edinboro, PA. The list of initial Verizon LTE cities is still unknown — except for San Francisco and Philadelphia — but we do know general areas that should be getting LTE soon; thanks to a previously leaked map. Edinboro, which is fairly close to Erie, appears to be marked as an LTE city on the leaked document. Also, the part of the IP address that is visibile is: 198.226; 198.226.0.1 appears to be owned by Verizon Wireless. It’s all speculative at this point, but isn’t it speculation that makes the anticipation even greater?

Thanks, Ryan! More →

Verizon almost eclipses 1 gigabit network speeds with a current FiOS deployment

Verizon almost eclipses 1 gigabit network speeds with a current FiOS deployment

The folks over at Verizon have just dropped a press release to boast about a very impressive feat. The company has just “completed a field trial in which it delivered approximately 1 gigabit-per-second bandwidth to a customer on the currently deployed gigabit passive optical network in a live production FiOS network setting.” Now that is some speed! The press release goes on to say: “Verizon’s GPON platform supports a total throughput of 2.4 Gbps downstream and 1.2 Gbps upstream to customers connected to the PON. This test successfully demonstrated the ability to serve customers on the FiOS network with Gigabit Ethernet (GigE) service.” The actual speeds recorded were 925 Mbps to a local server and 800 Mbps to a regional server 400 miles away; Verizon also said the increased speeds did not cause any kind of degradation in FiOS TV or residential FiOS phone services. The company said that this test proves that its current FiOS network has the ability to scale to meet the growing data demands of its customers. How many of you out there have FiOS? Is it available in your area? We’ve got the full press release after the break. More →

Clearwire to conduct LTE trials, promising unmatched speeds

Clearwire has long said that they have the technology, spectrum, and expertise to move from WiMax to LTE if necessary, and a press released today seems to reiterate that. Clearwire announced that it would: “conduct 4G LTE technology trials [...] in the U.S., and [...] test multiple coexistence scenarios between LTE and WiMAX radio technologies.” The release goes on to state that Clearwire, “expects the technical trials to demonstrate that Clearwire’s 4G network can deliver significantly higher performance using LTE technologies than any other operator,” and that they plan to “conduct the tests in collaboration with Huawei Technologies.” Huawei is the company that provided the infrastructure to the world’s first commercial LTE network in Europe. Who’s ready for a Verizon Wireless v. Clearwire LTE speed war! Hit the read link for the full release.

Ars Technica: Android 2.2 JavaScript performance "destroys" that of iOS 4

Ars Technica: Android 2.2 JavaScript performance "destroys" that of iOS 4

Android 22 iOS 4 Javascript Benchmarks

Ars Technica just pitted Google’s Android 2.2 against Apple’s iOS 4 in a JavaScript benchmark test…and Ars isn’t mincing words with their results. In a post titled ,”Android 2.2 demolishes iOS4 in JavaScript benchmarks,” Ars quipped: “The results show that the Android device delivers significantly faster JavaScript execution than the iPhone, scoring over three times better on V8 and almost twice as fast on SunSpider.” If you’re an Android fan you can go ahead and gloat, but this is exactly why a health mobile ecosystem is good for everyone. When companies — especially two with the resources of Google and Apple — compete, the consumers win. More →
