Sony Ericsson, Citizen, and others have been taking occasional shots at integrating Bluetooth into wrist-bound baubles for several years now, but the problems have been pretty obvious — Bluetooth wasn’t really optimized to transfer nibble-sized chunks of information while sipping almost imperceptible amounts of power, so you end up with a watch that dies in hours or days rather than years. That’s where Casio comes into play, showing off a prototype watch here at CES that makes use of Bluetooth Low Energy to connect to your phone and keep you abreast of calls and emails without the hassle of pulling the handset out of your pocket (or, worse yet, your belt-mounted holster). You can also silence alarms just by tapping on the watch, get your time synced, and generally look awesome while doing it — if it were a production unit, that is. Problem is that there aren’t any phones on the market with Bluetooth 4.0 support just yet, but Casio’s confident enough that they’re in the pipeline to say that they want to product their first BLE-enabled retail watches in 2011. The company is claiming two years of battery life off a single coin cell assuming twelve hours of use a day… so yeah, the benefits for this type of product are pretty clear. Follow the break for the full press release.
We were glad to see Bluetooth low energy actually added to the Bluetooth 4.0 spec, but of course the question remained: when are we going to get our hands on it? By Q4 this year, apparently — at least according to the Bluetooth SIG. But don’t expect any dramatic changes in battery life for most of your gadgets: while the low energy spec introduces connectivity to a host of lower-power devices that have in the past relied on proprietary technology (such as watches, pedometers, and cats), your traditional Bluetooth devices, such as phones and laptops, will consume roughly the same amount of power. Indeed, the low energy spec is merely throwing smaller devices (with smaller amounts of data to transfer) in to the mix: if you want Trans-Siberian Orchestra to sound as glorious as ever on your wireless headphones, you’ll need to push as much data (and hence draw as much power) with version 4 as you would with version 3. If you’ve ever heard “A Mad Russian’s Christmas,” you’d know what we’re talking about.
Chip maker Broadcom has unveiled no fewer than three new mobile-themed hunks of silicon this week in preparation for MWC in just a few days’ time. You ready for this? Alright, first up we’ve got the catchily-named BCM20751, which performs the rather ordinary tasks of GPS, Bluetooth, and FM radio management but also throws in an audio processor to offload some work from the phone’s primary CPU, which the company says can reduce battery consumption enough to improve playback time by up to 100 percent in some situations. Next up, we’ve got the BCM4751, a GPS receiver that Broadcom’s confident is going to set a new benchmark for mobile location-based services; a complete setup takes less than 30 square millimeters of precious board space and is claimed to be a guru at picking up weak signals all the while sipping power. Finally, the BCM2049 supports Bluetooth 2.1+EDR, FM (both transmitting and receiving), and Bluetooth Low Energy — something that was recently adopted for standardization in Bluetooth 4.0. All three should be on display at the show next week. That’s not all, though — the company is also announcing comprehensive support for Android across much of its product range, which seems like a pretty prudent business decision all things considered.
Bluetooth low energy and its predecessors (think Wibree) have been in the pipe for ages now, but we might actually see this tech take off en masse for the first time now that the Bluetooth SIG has officially added it into a release: 4.0. While Bluetooth 3.0 was all about high energy with the introduction of WiFi transfer, 4.0 takes things down a notch by certifying single-mode low energy devices in addition to dual-mode devices that incorporate both the low energy side of the spec plus either 2.1+EDR or 3.0. In a nutshell, the technology should bring a number of new categories and form factors of wireless devices into the fold since 1Mbps Bluetooth low energy can operate on coin cells — the kinds you find in wristwatches, calculators, and remote controls — and the SIG’s pulling no punches by saying that “with today’s announcement the race is on for product designers to be the first to market.” Nokia pioneered Wibree, so you can bet they’ll be among the frontrunners — bring it, guys.
