  • Six iPhone 4S features you may have missed

    Despite its superficial similarity to the iPhone 4, three landmark features set the iPhone 4S apart from its predecessor: Siri, the new 8 megapixel camera, and the much more powerful A5 processor. The iPhone 4S also comes with a few more subtle design tweaks that differentiate it from the iPhone 4, and you might miss some of those changes if you didn't have an iPhone 4 and 4S sitting side-by-side for a comparison. Antenna Improvements Phil Schiller actually did talk about the new antenna in the iPhone 4S during the most recent Apple event, but the changes to the iPhone's antenna aren't really obvious until you have the handset in your hands. One of those changes literally requires you to hold the device in your hand before you'll see it: the dreaded "death grip" of the iPhone 4 is gone in the iPhone 4S. A well-known and widely (over)publicized shortcoming of the iPhone 4's antenna design caused it to attenuate wireless signals when held a certain way. Bridging the black gap on the lower left side of the iPhone's antenna band would cause signal strength to drop for some users. This so-called "Antennagate" dominated headlines about the iPhone 4 for months, and Apple eventually addressed the issue by providing free bumper cases to affected users. Since I use my iPhone left-handed and without a case, with the iPhone 4 I always had to be mindful of how I held it. 3G signal strength at my home wasn't the best with my old wireless provider -- I'd get one or two bars if I was lucky -- so accidentally bridging that gap would cause my signal strength to drop to zero within a minute or less. That's no longer an issue with the iPhone 4S. In fact, to get the signal strength to drop at all I have to hold the phone in a very unnatural two-fisted grip that requires bridging all four of the black antenna gaps at once. The "death grip" is a thing of the past. The improved antenna design also equates to much faster 3G speeds, improved call quality, and lightning-fast Wi-Fi signal acquisition. 3G download speeds on my iPhone 4S are anywhere from two to four times faster than my iPhone 4 on the same network, and the murky "bottom of the ocean" call quality I got on the iPhone 4 was replaced with crystal-clear voice quality on the iPhone 4S. The newest iPhone also latches onto a Wi-Fi signal much faster than my iPhone 4 ever did, with essentially zero delay in connecting to networks it's connected to before. Many critics lambasted the iPhone 4's antenna design in the wake of "Antennagate," but the iterative update of the iPhone 4S antenna shows that Apple has shaken out any deficiencies in the design. Shifted Controls One consequence of the antenna re-design is those antenna gaps have been shifted around. Rather than the asymmetrical three-gap design of the GSM iPhone 4, the iPhone 4S has four gaps arranged with bilateral symmetry, essentially identical to the gaps on the CDMA version of the iPhone 4. As a result, the mute switch and volume controls for the iPhone 4S have been shifted downward toward the dock connector by about a millimeter compared to the iPhone 4, similarly to how the CDMA iPhone 4's controls were altered. As a result, many (if not most) cases designed for the GSM model iPhone 4 won't fit the iPhone 4S, including Apple's own bumper cases. Cases designed for the CDMA iPhone 4 should fit the iPhone 4S just fine. So should "universal" cases designed for both the GSM and CDMA versions of the iPhone 4; these cases feature slightly larger cutouts for the mute switch and volume buttons, so they should fit the iPhone 4S without issue. Quieter Vibration Motor Apple has swapped out the old vibration motor in the GSM model iPhone 4 with one that's either similar or identical to the one in the CDMA iPhone 4. The new motor features a smoother vibration which doesn't rattle the phone itself quite so much. The result is a much quieter vibration, one that you might not even hear from more than a few feet away if your iPhone's lying on a table; if you're holding the phone in your hand, you might barely hear the vibration at all. Depending on your needs, that might not necessarily count as an improvement. If you loathe ringtones and instead listen for your iPhone rattling across a table or other flat surface for your notifications, this change may disappoint you. Personally, I appreciate the new vibration, because the old one always sounded as though it was trying to shake the phone to shreds. The quieter motor in the iPhone 4S doesn't mean the phone's vibrations are weaker than those of the iPhone 4. I held the 4S in one hand and the 4 in my other; the strength of vibrations felt essentially the same, with the only difference being a distinctively loud BZZZZT coming from the iPhone 4. Audio Improvements The speaker on the iPhone 4S is NOTICEABLY LOUDER compared to the one in the iPhone 4. In some cases it's almost too loud; high-pitched notification sounds from apps like Tweetbot definitely have a piercing effect on my eardrums with the alert volume turned up all the way, which was never an issue with the quieter iPhone 4. The obvious upshot of the louder speaker is it'll be easier to hear ringtones and other sounds when you're in an environment with lots of ambient noise. Despite that increase in overall volume, the speaker in the iPhone 4S also seems to produce sounds with higher clarity than the iPhone 4's speaker. Audio that used to overdrive the iPhone 4 speaker and make it sound "clippy" now sounds much clearer on the iPhone 4S speaker. Music and games sound much better on the iPhone 4S, but the improved speaker clarity also means some ringtones or other media may actually sound worse than on the iPhone 4. For example, I sourced some of my custom ringtones from low-fidelity mp3 audio files; while they sounded fine on the iPhone 4 speaker, the flaws in recording quality are much more obvious on the iPhone 4S speaker, with very audible background hiss in some cases. Audio playback through both the iPhone 4S speaker and attached headphones produces a much less trebly sound than the iPhone 4. Music playback quality on the iPhone 4S also sounds subtly improved even through the included Apple-branded earbuds. Based on these sonic differences in music playback between the iPhone 4 and iPhone 4S, I suspected the iPhone 4S had a different audio processor; information in iFixit's teardown confirmed that though the audio codec chip is from the same manufacturer (Cirrus Logic) as the iPhone 4, the part number for the iPhone 4S is different. It's likely the updated audio codec chip is also part of the reason the iPhone 4S speaker sounds clearer than the iPhone 4. Your personal tastes may vary from mine. It's possible we could review the same hardware and come to entirely different conclusions about whether the iPhone 4 or 4S sounds "better" over headphones. There's no mistaking the improvements in sound quality through the built-in speaker on the iPhone 4S, though; it sounds markedly improved compared to the iPhone 4. Bluetooth 4.0 The iPhone 4S is the first iPhone to support Bluetooth 4.0, a low-energy Bluetooth spec that allows devices to sync via Bluetooth while consuming far less power than traditional Bluetooth devices. This low-power version of Bluetooth doesn't support voice -- headsets and other voice devices still have to transmit over one of the higher-power specs -- but it does support transmission of data from other peripherals like heart rate monitors, watches, and input devices like keyboards or game controllers. The applications for health and fitness-related gear are virtually endless. As of now, many third-party accessories require a proprietary receiver to send data to an iPhone, or else they transmit via one of the older, more power-hungry Bluetooth specs. Using Bluetooth 4.0 would allow these devices to communicate directly with the iPhone, without the need for an intervening dock connector dongle, and such devices could have tremendously increased battery life compared to those currently on the market. One example of a device that could greatly benefit from Bluetooth 4.0 is Jawbone's Up health monitoring band. The Up monitors a great deal of user health data, but syncing that data to the iPhone requires plugging a connector into the iPhone's headphone jack. Using Bluetooth 4.0 could theoretically allow a device like the Jawbone Up to be in constant communication with the iPhone 4S without the need for users to sync data manually. Another possible implementation of Bluetooth 4.0 would be a wristwatch that can display certain kinds of information transmitted to it from a synced iPhone (notifications, for example), and send basic commands back to it, such as controlling music playback. This has been a popular dream of geekier users ever since the current iPod nano debuted; once it became clear the nano could be used as a watch, people almost immediately leapt to the next-level idea of using the nano to control another device and/or display data transmitted to it. Not many Bluetooth 4.0 devices exist on the market as of yet, but expect to see a lot of them hitting the market once the standard becomes more widely adopted. The low-power spec allows devices powered by standard watch batteries to run with lifetimes measured in months to years rather than the hours to days of battery life current devices get. Video Mirroring The iPhone 4S is the first iPhone to support mirroring to an Apple TV via AirPlay, at 720p resolution. It also supports video mirroring or video out at 1080p resolution via Apple's Digital AV Adapter or VGA Adapter, the same connectors that allow for 1080p mirroring on the iPad 2. Video mirroring to an Apple TV will make it much easier to share content with people sitting nearby, and it also has great applications for gaming. None of these features are anywhere near as headline-grabbing as Siri, but the minor details that you might not even notice are often where Apple's products excel. The iPhone 4S is no exception.

  • Consumer Reports finds iPhone 4S to have worthwhile antennas, says newer iPhone 4 is still problematic

    "Consumer Reports recommends the iPhone 4S." It's only half a dozen words, but to the engineers (and marketers) at Apple, it spells "relief." After being profusely impacted by Consumer Reports' decision to recommend against buying the iPhone 4 due to those Antennagate issues, the entity has allowed all in Cupertino to breath a sigh of relief by effectively declaring the reception issue dead on the newest edition. To quote: "Apple's newest smart phone performed very well in our tests, and while it closely resembles the iPhone 4 in appearance, it doesn't suffer the reception problem we found in its predecessor in special tests in our labs. In special reception tests of the iPhone 4S that duplicated those we did on the iPhone 4, the newer phone did not display the same reception flaw, which involves a loss of signal strength when you touch a spot on the phone's lower left side while you're in an area with a weak signal. (The iPhone 4, which is still available, continues to exhibit that problem, we confirmed in tests of new samples of the phone. Because of the flaw, we continue to omit the iPhone 4 from our list of recommended models, despite its otherwise fine performance.)"In other words, even the newer samples of the iPhone 4 (perhaps even that one for Sprint?) continue to have antenna quirks, but at least the latest and greatest seems to have addressed 'em.

    Meet Krishna Naishadham and Xiaojuan (Judy) Song. They're researchers at the Georgia Institute of Technology, and those little devices they're holding may one day save you from an explosive device. This petite prototype is actually a paper-like wireless sensor that was printed using basic inkjet technology, developed by professor Manos Tentzeris. Its integrated lightweight antenna allows the sensor to link up with communication devices, while its functionalized carbon nanotubes enable it to pick up on even the slightest traces of ammonia -- an ingredient common to most IEDs. According to Tentzeris, the trick to such inkjet printing lies in the development of "inks" that can be deposited at relatively low temperatures. These inks, laced with silver nanoparticles, can then be uniformly distributed across paper-based components using a process called sonication. The result is a low-cost component that can adhere to just about any surface. The wireless sensor, meanwhile, requires comparatively low amounts of power, and could allow users to detect bombs from a safe distance. Naishadham says his team's device is geared toward military officials, humanitarian workers or any other bomb sniffers in hazardous situations, though there's no word yet on when it could enter the market.

    It's the problem that won't go away for LightSquared, and one that has prompted a number of different "fixes" and "solutions." The latest, as announced by the LTE wholesaler last month, is an actual hardware fix that overcomes the interference issue affecting high-precision GPS units -- the only problem being that all existing and future units will need to be upgraded with said fix. Now the company's back with yet more details, announcing that it's partnered with PCTEL to develop an antenna that lets users of high-precision GPS units easily retrofit their devices to make them "LightSquared-compatible." There's still no word on the cost for it, but LightSquared has also announced that Partron America has created a filtering component that costs $6. The company's press release is after the break.

  • Help for the lost: a fabric antenna to keep you from being a castaway

    Doesn't look like much, does it? But the next time you're lost at sea, you just might be thankful you've got it. That little square of fabric is actually a flexible antenna designed for the Cospas-Sarsat distress signal network, a Cold War-era system built to help pinpoint missing ships, planes and people. Designed to be sewn into a life vest, the antenna broadcasts an emergency beacon at a low frequency for greater range; in field tests, that helped rescuers find it within minutes. It's also tear- and water-resistant, which you'll be grateful for when you're being tossed around like a ragdoll in a sea of whitecaps. The technology was developed by the European Space Agency in partnership with a Finnish company. Next on their agenda? A round, floating companion for the marooned, codenamed Wilson.

  • Sezmi's cable / satellite alternative TV service to shut down Monday, won't be missed

    It's been almost two years since Sezmi launched its hybrid antenna and internet TV service, and now it has announced the dream of pay-TV without cable or satellite is dead. An email went out to customers tonight informing them the ability to view or record programming on their Sezmi systems would be shut off Monday, September 26th. The only compensation given for the sudden disconnect? Free access to the VOD catalog before that disappears too, on November 1st. The $20 / month Select Plus package that offered pay-TV channels over antenna never spread beyond Los Angeles, although users happy to settle for basic channels and online VOD had access in other markets. Still, we predict it won't be missed simply because it doesn't seem like many people ever signed up. Despite nice features like unique profiles for different household members, the limited sports selection cut off many early adopters from the beginning. The company is apparently trying to pivot into selling its technology to other service providers, we'll wait and see if a Moxi-like resurgence is in the cards.

  • Buckeyes embed antennas in clothes, couture to improve radio reception?

    We like what's in our wardrobe to be multifunctional, and we've seen threads do double duty as keyboards, flashlights and even drum kits in our day. Now, researchers at Ohio State have come up with a way to turn the shirt on your back into an omnidirectional antenna to boost radio reception. To do so, they etched brass wires into plastic film to create flexible antennae, and stitched 4 of them into the shoulders, chest and back of a vest. Using a computer controller the size of a deck of cards clipped to the wearers belt, the system senses body movement and activates the appropriate antenna to get the best signal. You see, antennae don't work so well when touching human skin -- as any iPhone 4 owner can attest -- and the multiple antenna system alleviates that problem while providing "significantly greater signal strength" than a standard antenna. The researchers see the technology having great appeal for the military, law enforcement, and emergency personnel, but here's hoping they make a consumer version, too. It'd be nice to eliminate all those cell-service dead spots by simply donning a jacket, right?

    As the world waits for Apple to release the iPhone 5, Reuters is reporting that Cupertino may be refreshing the iPhone 4, as well. According to two anonymous sources "with knowledge of the matter," an unnamed Korean manufacturer has already begun producing parts for a cheaper, 8GB version of the smartphone, slated to launch within the next few weeks. As for that next-gen handset, the insiders went on to say that the iPhone 4S / iPhone 5 will feature a more spacious touchscreen, better antenna and eight megapixel shooter, and that Apple is indeed aiming for a late September launch, after having already asked manufacturers Hon Hai and Pegatron to prep their facilities for the production of 45 million units, altogether. Details, as usual, are still scarce at this point, but we'll let you know as soon as we get more information.

  • Australia's first mobile network celebrates 30th birthday with a quiet night in

    Why is this phone staring at the ground in dismay? Because it can't believe that it's been 30 years since it made history. On this day three decades ago, this 14 kilogram beast was used to place the very first call on Australia's very first mobile network -- the Public Automatic Telephone System, operated by Telstra (or Telecom, as it was known at the time). Back then, the network could only support 1,000 users at once and provide coverage for the greater Melbourne area (things have since changed for the better). The device, meanwhile, was known simply as The Mobile Phone and, in retrospect, wasn't all that mobile; the carphone system included a 45 centimeter handset, a transceiver and rooftop antenna -- all for a little over $5,000. It could also store a whopping 16 phone numbers and would notify users of incoming calls by sounding the car's horn and flashing its headlights. The Mobile Phone's Australian reign, however, would be relatively short-lived, with the DynaTAC 8000x ushering in a new handheld era, just two years after Telstra's inaugural call. Dial past the break for a Wagnerian commercial that'll tell you everything you always wanted to know about antiquity, but were too afraid to ask. [Thanks, Vincent]

  • Russia's RadioAstron telescope finally set to launch, blanket space with its radio eye

    Considering all the space nostalgia we've been swimming in recently, it's somewhat appropriate that a Cold War-era telescope is gearing up to make its maiden voyage, after more than three decades of development (and delays). The Russian mission, known as RadioAstron, will finally become a reality on Monday, when a radio telescope launches from Kazakhstan's Baikonur cosmodrome before soaring into orbit some 350,000 kilometers away from the Earth. At just ten meters in width, the craft's antenna is small in comparison to other radio 'scopes, but its reach can be dramatically expanded when combined with signals from those on the ground. This technique, called interferometry, will effectively create the largest telescope ever built, covering an area nearly 30 times the Earth's diameter and allowing RadioAstron to capture interstellar images in 10,000 times the resolution of the Hubble Space Telescope. There remains, however, one major hurdle -- because the spacecraft collects data at about 144 megabits per second, it must constantly transfer information to antennas on the ground. Problem is, there's only one antenna capable of receiving RadioAstron's signals and, unless others are constructed soon, a healthy chunk of its observations could be lost. How do you say "buzz-kill" in Russian?

  • Apple patent app sheds light on wireless charging dreams, NFMR love affair

    Apple threw quite the wireless party by introducing PC Free and iCloud at yesterday's WWDC keynote, but it seems that the engineers in Cupertino may have even more tricks up their sleeve. Judging by a recently filed patent application, the company's hoping to add charging to its list of cord-cutting services. Specifically, the patent describes building a NFMR (near-field magnetic resolution) power supply directly into your iMac so it can charge your iPhone, iPad, or even peripherals -- such as a keyboard or mouse, when equipped with a special antenna -- without the assistance of your ol' trusty charging cords or batteries. Sporting a somewhat mature iMac that's operating sans NFMR? Pop a special USB dongle in that bad boy and presto, you're good to go. The patent points out that the range is limited to one meter, though there may be ways to install repeaters in peripherals to extend that distance further. Of course, patents won't guarantee we'll be grabbing the scissors to cut our cords anytime soon, but at least we won't have to rely on these things for the rest of eternity.

    Before you and your pooches head out to hunt innocent ducks this year, you might wanna check out Garmin's new Astro 320 dog tracker -- a handheld GPS device designed to help hunters keep even closer tabs on their four-legged sentries. The latest addition to the Astro family can simultaneously track up to ten hunting dogs per receiver, with a revamped antenna and three-axis electronic compass covering up to nine miles of flat terrain. Boasting a 20-hour battery life, the 1.7GB handheld can also tell hunters whether their canines are running or pointing, while its mapping capabilities provide their precise coordinates relative to powerlines, buildings, and individual trees. All this information is displayed on a 2.6-inch display, where users will be able to access 100k or 24k topographic and satellite maps. A keypad lock function, meanwhile, will make sure you don't accidentally press any buttons while you're in the thick of a hound-led hunt. The handheld will be available in July for $500, with the full system (including a DC 40 tracking collar) priced at $650.

    Think your body's a temple? Turns out it's actually just the antenna the temple's staff uses to watch football when they're done praying. A group of engineers from Microsoft Research showcased a technology at Vancouver's Conference on Human Factors in Computing that offers gesture-based control on a scale that could make the company's Kinect controller downright laughable. The team demonstrated how it could harness the human body's reception of electromagnetic noise to create gesture-based computer interaction that does away with the need for a camera -- though a receiver is worn on the body (the neck, in this case). The system uses the unique signals given off in different parts of the home to help measure the interaction, effectively turning one's walls into giant control pads, which can regulate things like lighting and the thermostat. Hopefully games, too, because we can't wait to play Pac-Man with our bedrooms.

    By now you've probably watched iFixit's recent iPad 2 teardown video several times while drooling profusely, but we just know you're itching to find out what's different with the innards of the WiFi-only, GSM, and CDMA versions. Well once again, iFixit's got you covered -- via an "exceptionally cool" user-contributed post, this time. A grand total of three iPad 2s were sacrificed in this round, revealing variations in case design, antenna count, WWAN board layout, radio chipset choices, and headphone jack assemblies. Besides clearly visible changes like the black antenna window on the 3G models and the microSIM slot on the GSM version, it's interesting to note that Apple made the same design choices with the iPad 2 and the iPhone 4. The CDMA model features an additional antenna over its GSM sibling, and uses a Qualcomm Gobi dual-mode radio which supports both CDMA and GSM -- the latter being unused -- along with an integrated GPS receiver, just like the iPhone 4 for Verizon. The GSM version, meanwhile, uses an Infineon chipset for GSM and a separate Broadcom module for GPS, just like the global iPhone 4.

  • iPad 2 3G antenna causing problems with mic clarity

    Apple apparently moved the iPad 2's microphone to the top center of the device, and that's causing problems in performance across the Wi-Fi and 3G models, says iLounge. The 3G model's mic is set in a different material than the Wi-Fi version (because of the extra antenna), and that means that the Wi-Fi version sounds "markedly cleaner" than the other versions, with the CDMA model sounding the most "slightly muffled and echo-prone." The problem is reportedly exacerbated when the mic is facing away from its target, like when you're using the iPad for FaceTime. I doubt this is a deal-breaker for most users, but it is probably something we'll see fixed in the next version of the iPad. It's interesting that this either never came up during Apple's testing, or it did and the company simply decided that it was good enough to let slip by. Meanwhile, if you need a nice clear microphone for your 3G iPad to use, there are other third-party solutions to check out as well.

  • AnandTech research shows Verizon iPhone 4 'death grip' reports are overblown

    Consumer Reports tested the Verizon iPhone 4 using the same methodology as the original GSM version, and with the same results: signal strength drops if the iPhone 4 is gripped in a certain fashion, commonly known as the "death grip." As a result of its testing, Consumer Reports decided it couldn't recommend the Verizon iPhone 4, either. Similar testing done by AnandTech throws some cold water on Consumer Reports' findings, however. Not long after the Verizon iPhone 4's launch, AnandTech found the Verizon iPhone 4's "death grip is essentially mitigated." The Verizon iPhone 4 experienced a signal loss of 16.5 decibels (dB) when held in "death grip," compared to signal loss of 15.5 dB when held "naturally." This is far better performance than the GSM iPhone, which experienced signal loss of 24.6 dB in "death grip" and 19.8 dB in "natural grip." In other words, the Verizon iPhone 4 in "death grip" mode experiences less signal degradation than a GSM iPhone 4 held "naturally."

  • Alcatel-Lucent's lightRadio shoves a base station in a box, minimalists cheer

    They've been fashioned after palm trees, Christ on the cross, and what look to be Dyson Ball vacuum attachments. But now, Alcatel-Lucent is giving cellphone towers a makeover that might actually stick. The company's new broadband base station solution, known as lightRadio, eliminates the need for cumbersome huts at the base of cellphone towers and packs antennas into a series of 2.5-inch boxes, while simultaneously improving capacity and reducing cost. These so-called radio cubes combine 2G, 3G, and LTE antennas with an SoC for processing, making them small enough to prop up on a lamp post. They're firmware upgradable, and utilize beamforming to more efficiently connect to wireless devices; according to the company, groups of 'em can not only increase broadband capacity by 30 percent, but also cut operation costs and CO2 emissions in half. Clearly, lightRadio makes a compelling case for narrowing the digital divide, but it won't be available broadly until 2012, which means the creative cover ups will just keep on coming. Sorry, JC.

  • Research shocker! Keyless car entry systems can be hacked easily, elegantly

    We know you are vigilant enough not to trust your car's security to a wireless system, but plenty of other folks like the convenience of putting away the metallic keys and getting into their vehicles with a bit of Bond-like swagger. Professor Srdjan Capkun of ETH Zurich found himself perched on the fence between these two groups when he recently purchased a vehicle with a keyless entry system, so he did what any good researcher would: he tried to bypass its security measures. In total, he and his team tested 10 models from eight car makers and their results were pretty conclusive: each of the tested vehicles was broken into and driven away using a very simple and elegant method. Keyless entry systems typically work by sending a low-powered signal from the car to your key fob, with the two working only when they're near each other, but the wily Zurich profs were able to intercept and extend that signal via antennas acting as repeaters, resulting in your key activating your car even when it's nowhere near it. The signal-repeating antennae have to be pretty close to both the key and the car, but that's why heist movies stress the importance of teamwork. Hit the source link for all the chilling details.

  • Verizon iPhone reportedly unaffected by "death grip" issue

    After getting their hands on the Verizon iPhone at yesterday's press event, several people have noted that it seems unaffected by the "death grip" phenomena that troubled iPhone 4 users last year. First up, Ars Technica's Chris Foresman noted that gripping the phone by its edges did not cause any CDMA signal reception attenuation, even during a call. Slashgear's Evan Sellek reported a loss of one bar while bridging the antenna gap (from four out of five to three out of five), noting that, "...we still couldn't reproduce the 'death grip' symptoms that plagued the initial launch of the iPhone 4 ... it looks like Verizon's confidence in the iPhone 4 on their network seems to be pretty sound." Finally, PCMag's Sascha Segan managed to bridge all four gaps -- an uncommon way to hold an iPhone for sure -- and only lost a single bar. We noticed right away that the antenna had been redesigned for Verizon, with the notches shuffling about a bit. Sure, you'll need a new case, but that's a small concession to make for a phone that can actually place and receive phone calls.
