MrSeb writes "Rohm, a Japanese semiconductor company, has created a silicon chip and antenna that's currently capable of transmitting 1.5Gbps, with the potential to scale up to 30Gbps in the future. While this is a lot faster than anything currently on the market, the significant advance here is the reception and transmission of terahertz waves (300GHz to 3THz) using a chip and antenna that's just two centimeters long. Rohm says it will only cost $5 when it comes to market in a few years — a stark comparison to current terahertz gear that's both large and expensive. The problem with terahertz transmissions, though, is that it's highly directional — with a submillimeter wavelength, it's more like a laser than a signal. Terahertz waves might enable awesome device-to-device networks, but it isn't going to bring 30Gbps internet to a whole city block. More interestingly, submillimeter terahertz radiation is the next step up from the gigahertz radiation used in full-body millimeter wave scanners. Terahertz waves can not only see through clothing, but can also penetrate a few millimeters of skin."

dkd903 writes "According to reports from Macotakara, Hitachi Displays Ltd and Sony Mobile Display Corporation has started shipping the screens for the iPad 3 and a 4-inch LCD screen for an unnamed iOS device. It would be fairly safe to assume that the 4-inch display will be for the next iPhone – the iPhone 5."

An anonymous reader writes "The attempted merger between AT&T and T-Mobile has fallen on hard times amid antitrust concerns, but there's a potential silver lining for T-Mobile — one that would give them a boost over competitors anyway. Reuters reports that T-Mobile USA would be entitled to a hefty breakup fee including $3 billion in cash as well as spectrum and roaming agreements. 'In a research note, Moody's said that could also lead to a network sharing deal between the two companies, reasoning that it "would make sense given the spectrum that AT&T will have to cede to T-Mobile and the 3G roaming agreement between the two." That would make life especially hard for No. 3 U.S. carrier Sprint, which has been one of the most vocal opponents of the AT&T/T-Mobile deal, going so far as to file a lawsuit. ... Smaller rivals such as MetroPCS and Leap Wireless may be affected even more because T-Mobile is eyeing similar customer segments.'"

New submitter sirjohn writes with the good news that "A small group of ICS and Nokia engineers have started working on a minimal bootstrap to bring fully functional Qt 5" to the Raspberry Pi, writing "Do you want to create the next big thing on embedded devices and have $35 to invest? You can now have a complete development environment with accelerated graphics for basically nothing. I think it's a big deal ..." Plus, Nokia is funding 400 of the boards and looking for ideas (and developers) to use them. The competition is stiff; there are already quite a few impressive ideas listed.

An anonymous reader writes "Patent firm IPCom announced today that it wants a ban on sales of HTC's 3G smartphones in Germany, after HTC dropped its appeal to a patent ruling IPCom won. HTC says the appeal was dropped because another patent court partially invalidated the patent in question, but IPCom is pressing forward to try to dampen HTC's holiday sales. 'IPCom, based in Pullach, Germany, is seeking royalties from a family of mobile-technology patents it acquired in 2007 from Robert Bosch GmbH, the world's largest automotive supplier. IPCom bought the patents after Bosch failed to license them to Nokia in 2003.'"

symbolset writes "Update from an earlier story here, where Carrier IQ was pursuing a security researcher for pointing out privacy issues in an application alleged to track and record the activities of smartphone users. The company has relented, and retracted their Cease and Desist letter. In their press release [PDF] they say: 'As of today, we are withdrawing our cease and desist letter to Mr. Trevor Eckhart. We have reached out to Mr. Eckhart and the Electronic Frontier Foundation (EFF) to apologize. Our action was misguided and we are deeply sorry for any concern or trouble that our letter may have caused Mr. Eckhart. We sincerely appreciate and respect EFF's work on his behalf, and share their commitment to protecting free speech in a rapidly changing technological world.' Notch another win for the Streisand effect."

angry tapir writes "The battle over scarce radio spectrum that has embroiled the mobile broadband world even extends to a little-known type of wireless network that promises to reconnect the human nervous system with paralyzed limbs. At its monthly meeting next week, the U.S. Federal Communications Commission will consider whether four sets of frequencies between 413MHz and 457MHz can be used by networks of sensors implanted in patients who suffer from various forms of paralysis. One intended purpose of these MMNS (medical micropower network systems) is to transmit movement commands from a sensor on a patient's spinal cord, through a wearable MCU (master control unit), to implants that electrically stimulate nerves."

itwbennett writes "How much does it cost to make a phone app to tell local temperature and suggest how not to get heatstroke, such as drink water and avoid alcohol? If you're the U.S. Government, it'll cost you a pretty penny. Using MuckRock to file a Freedom of Information Act, Rich Jones of GUN.IO discovered the Department of Labor, Occupational Safety and Health Administration paid $106,467 for the Android version; $96,000 for the iPhone version, and an additional $40,000 for a BlackBerry app that never got distributed."

antdude writes in with a story about two U.S. malls that plan on tracking shoppers' movements by monitoring the signals from their cell phones this Friday. "The management company of both malls, Forest City Commercial Management, says personal data is not being tracked. 'We won't be looking at singular shoppers,' said Stephanie Shriver-Engdahl, vice president of digital strategy for Forest City. 'The system monitors patterns of movement. We can see, like migrating birds, where people are going to.' Still, the company is preemptively notifying customers by hanging small signs around the shopping centers. Consumers can opt out by turning off their phones."

As a security researcher, Moxie Marlinspike has played a big role in explaining what can go wrong in using Certificate Authorities to authenticate SSL traffic, an issue that's been top of mind this year thanks to compromised and faked certificates. On that front, he's lately come up with a system designed to circumvent CAs entirely, which means bypassing compromised (or invidious) authorities, rather than trying to patch the CA system. Another line of research, but not the only one, is mobile security and privacy; his Whisper Monitor Android firewall, released earlier this year, gives Android users notifications (and fine-grained permissions) when apps — including location-tracking or malware apps — want to make outbound connections. Possibly related: Moxie can also speak first-hand about what new border-search policies mean for travelers, having had his laptop and phones seized on returning to the U.S. from a trip. (And by the way, he's also an accomplished sailor and film-maker.) Moxie's agreed to answer your questions. Ask as many questions as you'd like, but please, be kind of rewind^wask don't ask unrelated questions in the same post.

phaedrus5001 sends this quote from a story at Wired: "A data-logging software company is seeking to squash an Android developer's critical research into its software that is secretly installed on millions of phones, but Trevor Eckhart is refusing to publicly apologize for his research and remove the company's training manuals from his website. Though the software is installed on millions of Android, Blackberry and Nokia phones, Carrier IQ was virtually unknown until the 25-year-old Eckhart analyzed its workings, recently revealing that the software secretly chronicles a user's phone experience, from its apps, battery life and texts. Some carriers prevent users who actually find the software from controlling what information is sent." The EFF is hosting PDFs of CarrierIQ's C&D letter, as well as their response on Eckhart's behalf.

jfruhlinger writes "AT&T's plan to merge with T-Mobile just hit a pretty big snag. The FCC declared the merger would be anti-competitive and not in the public interest." According to the NY Times, the FCC seeks to hold a hearing before an administrative law judge in which the burden would be upon AT&T to prove the deal isn't anti-competitive.

hweimer writes "I am looking for a small (7") tablet that comes with root access out of the box. I know, I could get one of the usual suspects and root it myself, but I don't want to waste my time in the process and end up voiding my warranty. Basically, I'd like to use it for web browsing, reading PDFs and accessing my e-mails via SSH (extra bonus for X11 forwarding). Any good suggestions, or should I wait for Tizen devices to hit the market?"

ProbablyJoe writes "AllThingsD is running a series of stories this week about a possible new Facebook phone, codenamed 'Buffy.' The phone is said to be in development by HTC, who collaborated with Facebook earlier this year for the Salsa and ChaCha/Status phones, which both had physical Facebook buttons, and a degree of integration with the social network. While these rumors have been going around for quite a while, the article contains some new information, and neither Facebook or HTC are denying the rumors. The phone will be based on Android, but like Amazon's Kindle Fire, will be heavily modified to integrate with Facebook, potentially using Facebook's HTML5 platform. While we're unlikely to see any official announcements or releases any time soon, Facebook are eager to compete with Google and Apple, and are likely to want a phone of their own on shelves as soon as possible."

An anonymous reader writes "After many years I am finally considering entering the smartphone era. Within the mainstream, there seem to be four OS choices: Windows, Android, Blackberry, or iOS: Android comes out as clear winner to me. However, all of the choices in one way or another require sharing a lot of personal information in the Cloud run by their respective corporations. Let alone Blackberry's centralized mail servers; there is no way to have an Android smartphone working decently without sharing all of your contacts, calendar appointments, and other stuff with Google. While Android is less intrusive than iOS, the lack of privacy remains quite annoying no matter how comfortable it is to have your own calendar and contacts centralized. In 2011 is there any option, other than living in a cave, to keep one's own life private while enjoying the wonders of modern smartphone apps?"

wiredmikey writes with this quote from an article about determining whether the recent doom-and-gloom reports about malware on mobile devices are justified: "As twilight approaches for 2011, security vendors have set their gaze on the rise of Android malware during the year and what is ahead. Last week, Juniper Networks entered the fray, declaring the number of malware samples it observed targeting devices running Google Android had shot up nearly 500 percent since July. Today, McAfee released its threats report for the third quarter of the year, which found that the amount of malware targeting Android devices jumped 37 percent since the second quarter. While there is no doubt the amount of malicious programs with Windows in their bull's eye dwarfs the amount of threats to mobile devices, the focus on Android malware have left some wondering how to separate fact from hype."

Several media sources (here's PC Magazine's version), all seemingly based on an account at SemiAccurate citing (but not naming) "multiple sources," report that Apple originally planned an AMD-chip based MacBook Air, rather than the Intel-based version that emerged later ("Plan B," says the report).

MahlonS writes "I am a retired network hack wintering in my RV in a campground in southern GA. 3 years ago I reconfigured the Wi-Fi system to a marginal working ability; It's now ready for a serious upgrade, prompted by a new cable net connection replacing a weak DSL. 5 dual-radio HP Curve access points connect to a 6th via single or double radio hops (effectively a Wireless Distribution System) in heavily wooded space. Unidirectional antennas at the APs (the APs are in water resistant enclosures) are placed on poles above the RVs, about 15 feet above ground. Primary hops are about 300 feet to 3 of the APs, secondary hops about the same. Signal measurements indicate that there is adequate RF between the access points. In 2008, average user count averaged about 30 users; newer devices (smart phones, etc) will likely increase that number (winter population total is about 80 RVs). While the old design worked OK when lightly loaded, I suspect that the single DSL line generated so many packet resends that the APs were flooded. This is a quasi-State Park, so money is always an issue, but there is enough squawk from the user community that a modest budget might be approved. The main AP connects to an old Cisco router. Burying wire is frowned upon, due to shallow utilities, and campfire rings that float around the campsites — sometimes melting TV cables. Since I'm not up on current Wi-Fi tech, are there solutions out there that would make this system work much better?"

The mixed reviews so far available for the new Amazon Fire tablet mostly address the Fire in its intended role as a locked-down portal through which to buy and consume ready-made content from Amazon. New submitter terracode writes with a different kind of review, which "goes into depth on the Kindle Fire's hardware, and provides details on how to root and tweak the tablet." The article also provides a friendly chart comparing the hardware in the Fire to that of the Nook Color and the iPad 2.

"The MacBook Air and the Ultrabook come without a piece of hardware that's been a mainstay in laptops for a long time — the optical drive," says a piece at CNET. "Maybe because they really aren't that necessary anymore." I would have thought otherwise a few years ago, but traveling in the meantime with a small netbook was certainly handy. Since that machine died, I think I've used the optical drive in its low-end laptop successor a grand total of once, which was to test its wireless compatibility with a Live CD Linux distro.
