LTE Upgrade Will Let Phones Connect To Nearby Devices Without Towers

An anonymous reader sends this excerpt from MIT's Technology Review: A new feature being added to the LTE protocol that smartphones use to communicate with cellular towers will make it possible to bypass those towers altogether. Phones will be able to "talk" directly to other mobile devices and to beacons located in shops and other businesses. Known as LTE Direct, the wireless technology has a range of up to 500 meters, far more than either Wi-Fi or Bluetooth. It is included in update to the LTE standard slated for approval this year, and devices capable of LTE Direct could appear as soon as late 2015. ... Researchers are, for example, testing LTE Direct as a way to allow smartphones to automatically discover nearby people, businesses, and other information.

Then D2D can be used locally by public safety people to communicate with anyone having a LTE device supporting D2D (and the vision is that in time, everybody will).

Messages posted to Sina Weibo, a Chinese microblogging site similar to Twitter, are being blocked in far greater numbers than normal.

    In response, a different type of social network has come to the fore. The Firechat app allows smartphone users to talk to one another "off-the-grid", in the absence of a mobile signal or access to the internet. By making use of Bluetooth and Wi-Fi, messages are spread in a daisy chain fashion, jumping from one user to the next. The system is particularly effective when large numbers of people are congregated together - like at a music festival, or a political protest.

    Micha Benoliel, CEO of Open Garden, the firm that makes the app, tells BBC Trending there has been a huge surge in downloads from Hong Kong, as more than 100,000 new accounts have been created in less than 24 hours. Usage spiked during protests in Taiwan and Iran earlier this year, but never before on this scale, says Benoliel.

    The OLPC (One Laptop Per Child) project had this capability from the start. Their normal setup is a flock of laptops with only wireless comm hardware, all talking to and relaying messages for their neighbors, plus a wired machine somewhere in the area that provides access to the outside world.

    Actually, this was the intended "normal" situation back in the ARPAnet era. It didn't make sense to the military funders to rely on a single relay machine that would be an easy target. But suppliers of the commercial Internet never liked the idea, because they've always wanted to charge customers for every device with access. A flock of devices using a single member's Internet access was explicitly banned at first because of this. As they slowly realized that they couldn't continue to hold the Internet back that way, they switched to the approach of software that hands packets to a single router/gateway box, and not directly to any neighbor.

    We still see this very clearly with email, which on most customers' gadgets requires sending a message to an email "server" (typically on an ISP's machine), rather than directly to the target machine. If members of your family want to send messages to each other's gadgets, do the messages go directly to their machine? Or do they go to an address on some company's machine, which tells the recipient that they have a message? This isn't accidental; it's done that way so that the company has access to all your messages, and you have to continue to pay them or lose the ability to send messages to people within your own household.

    This isn't necessarily silly. I live in a house with 3 floors (plus a basement ;-). Such verticaly houses are fairly common here in New England. My wife's "home office" is in the (half-size) top floor, a finished attic actually, and if I'm working a couple of floors lower, messages like "Lunch?" or "Mail's here" are much faster by email or IM than by running up and down stairs. It's often annoying when local IP packet storms (especially at lunch/dinner time) interfere with delivery of such messages. This sort of "insignificant" traffic would work better if the original machine-to-machine design were implemented. But the commercial ISP market would lose if they couldn't charge for (and read) such traffic, so we can expect them to fight it.

    Yes, because p2p comm during extended blackouts is trivially easy to maintain in the face of depleting battery power (Also, extended blackouts are oh-so-common in modern life). File transfers? Don't we already have a tech called bluetooth for that?

    Fucking luddites on a tech site.

    Yes, we have wifi, and bluetooth, and whatever, but LTE could be a technology to rule them all. Imagine having one protocol that could scale from pico home sites to nationwide networks. Having your phone connected to a home LTE hotspot that sits on your free fast wired internet connection, that then seemlessly hands over when you leave the house to standard mobile comms, or does P2P when you're physically near someone and need a photo or video from their device. We could do away with a whole bunch of different technologies potentially and replace them with one overarching wireless protocol that is better than them all.

    When there is a real disaster and a provider (AT&T, Verizon, etc) wants to restore service, they typically bring a tractor trailer full of hardware, a generator, plus a huge mast antenna, all just to serve as a temporary cell site. It's a bit of a stretch to think that a new trick in the LTE protocol will make all of that magically happen between handsets without being a huge drain on each handset (making them die even faster in an area where they probably cant be easily charged). This will be more of a gimmick to let the handset get data from nearby devices, like a dinner menu or a coupon for $1 off dog food (in exchange for some juicy personal data, of course).

    How do you propose it gets around blackouts? If it did you would have the entire epicenter relying on fringe cell phones for service. It's like having an entire town piggy backing on a handful connections. Those who are in range will have their batteries toasted before you could say YouTube.

    Well, one thing that might help is a "social responsibility" campaign. Publicise the fact that this is an inherent problem, and the solution is for as many people as possible should be prepared with extra batteries; portable battery packs, etc. Explain to people that the system will only work if enough people have the extra power in their pockets to keep the messaging system alive. And that, in an emergency situation, they might avoid using sites like youtube. ;-)

    Granted, some people will enjoy leeching off the rest of us. But it's possible that, by calmly explaining the situation to people, most of us will do what it takes to keep the system up and running.

    Transmitting uses much more power than receiving. This peer-to-peer method may play havoc with battery life in a weak cell reception area. I hope they are considering that ramification in the design and metering of the service. How much traffic should one phone carry and how does it benefit the phone holder? Perhaps a credit scheme for carrying traffic?

    Existing cell technology does not support proper authentication. Your mobile device is authenticated, but cell towers are assumed to be trusted and you have no control over what you connect to. This allows all kinds of Man in the Middle attacks, where one could pretend to be a cell tower and capture traffic.

    Hypothetical example - you are standing next to a cartoon robber with a big black box called "FAKE CELL TOWER". The only way you could prevent your smartphone from getting connected to this device is to turn data off. Once you connect, attackers can push fake app updates, inject exploits into your browsing, inspect your unencrypted traffic, try to get you accept compromised certificates, redirect your traffic and so on.

    And this is why I am not excited about LTE direct.

  52. Bypass Towers by DarthVain · · Score: 1

    Presumably given enough coverage of 500m phones, no towers would be necessary at all with the right software... That is so long as you can communicate with the nearest 500m LTE phone, it could potentially pass it on to the rest of the network... Of course there would be issues with the organization of such a network in a distributed fashion and performance issues when you have someone important being the only link between many users and a single phone trying to handle more transmission than it can handle.

    It would be an interesting thing to try, particularly in a dense city. It could also work forming small networks anywhere really, given the phones, people, and proximity..
