It's Like Bluetooth, But Without All The Pain
from the all-hail-progress dept
The Bluetooth wireless communications technology has become commonplace these days -- almost in spite of itself. While Bluetooth can be exceptionally useful for short-range communications, it can also be an enormous pain to use, in particular because of the pairing process users must go through to connect devices for the first time. Enter the new TransferJet standard, which is being backed by a number of digital camera makers who want to simplify the transfer of images and video. TransferJet can operate at speeds up to 357Mbps, 100 times faster than Bluetooth, and it doesn't require any pairing, it simply kicks in automatically and begins transfers when a compatible device is placed within 2 millimeters of the "transfer area" of a receiving device, like a PC. The cumbersome pairing process from Bluetooth has been replaced simply by proximity -- the thinking is that if a device like a camera can be placed within 2mm of a receiving device, the owner is okay with the transfer. While obviously this sort of security doesn't work in every scenario, it's good to see engineers learning from the usability foibles of previous technologies.Filed Under: bluetooth, transferjet
Mixed Decisions Concerning Police Searches Of Your Mobile Phone On Arrest
from the legal-or-not? dept
A year ago, we had a lively discussion around here concerning the legal question of whether or not police could search your mobile phone if you are stopped for a traffic violation. It seems that the question is far from settled. Declan McCullagh details two separate lawsuits in which judges came to opposite conclusions about the rights of police to search mobile phones or other devices on persons being arrested. It's clearly allowed to search through physical belongings -- but when it comes down to digital belongings, it's not at all clear. It comes down to the same issue being debated concerning laptop searches at the border. Traditional law concerning such searches assumes that what you have on you is stuff you purposely chose to bring on that trip. However, in a digital age, where your devices "keep everything" the opposite is true. You automatically bring everything and only exclude that which you purposely choose to leave out. Thus, the old laws don't really make much sense and could lead to some dangerous and highly questionable scenarios. Hopefully, the courts will recognize this before too long.Filed Under: mobile phones, searches, warrants
What Would Pushing Back The Digital TV Transition Mean?
from the on-hold dept
As the deadline for the shutdown of analog TV broadcasts and the transition to digital draws closer, calls for a delay in the switchover grow louder, thanks largely to poor management of the converter subsidy program and inadequate education. But while consumer groups and politicians fret over the few million people who will need converters but haven't gotten them, Kevin Fitchard over at Telephony Online has a nice roundup of the wireless and mobile companies that will feel the effects of any delay in the transition.The reason for the digital switchover is to free up the 700MHz spectrum that's used by analog broadcasts. The spectrum's low frequency gives it great propagation characteristics for mobile broadband, while the sheer quantity of it the TV broadcasts occupy translates into a lot of capacity for next-generation mobile networks. Also, keep in mind that the government has already auctioned off the licenses to this spectrum, so companies like Qualcomm and Verizon Wireless, which have already shelled out billions of dollars to set up shop in it, will have to push back their investments and rollouts. This could have a carry-on effect on consumers. For instance, Cox Communications bought 700MHz licenses in many of the markets in which it offers cable TV service with the intention of setting up its own mobile networks, introducing new competition for incumbents. One other group that stands to lose out if the transition is delayed: public safety agencies, which were allocated 700MHz spectrum in order to build interoperable, unified communications systems. This transition has been pushed back for years; it's important now that the hard deadline stands, and that the vast amount of spectrum used by the analog broadcasts -- broadcasts that relatively few people rely on -- can be refarmed and put to a more valuable use.

Group Wants A National Ban On Yakking While Driving
from the no,-there's-nothing-else-going-on dept
As the nation gears up for the inauguration of a new President and Congress and state and local governments laying out their legislative priorities for the coming year, one group says that in addition to pressing issues like the economy, legislators should take up a nationwide ban on cell phone use while driving. They've trotted out the usual rhetoric, equating yakking while driving to drunk driving in an attempt to evoke an emotional response, but ignoring some salient facts. First, while it's hard to argue that driving while talking is completely safe, it may not be as big a risk as some of these groups would lead us to believe. Second, the laws are very hard to enforce and don't automatically decrease the number of accidents. Instead of adding another law narrowly focused on one particular behavior, why not more stringently enforce existing traffic laws dealing with dangerous driving? Laws already exist covering all manner of unsafe driving; perhaps a good way to make the roads safer would be to increase enforcement of them and work to clamp down on all types of unsafe driving, rather than single out particular ones.Filed Under: driving while yakking, laws, regulations
