While Wi-Fi and WiMAX get all the big hype, there is another popular wireless protocol that is still going strong. That of course is Bluetooth, the PLAN (or personal local area network) protocol. And now the technology is getting a Dick Tracy worthy makeover ala watches. These have been around for a while, but soon could be replacing other wireless technologies for broadcasting short distances.
The Bluetooth Special Interest Group (SIG) has announced that the forthcoming Bluetooth Core Specification Version 4.0 will feature powerful low energy mode that could have new applications for health, sports and fitness as well as for security and home entertainment. This could mean that Bluetooth technology could be used for heart rate monitors, cycle computers, running computers and other devices that currently work on RF protocols. The benefit of Bluetooth is that it could send the information up to 200 feet, rather than just a few dozen inches. It could also work to transfer information from a monitor to a computer after a workout.
It could also be more reliable than RF, and for anyone that’s tried to get a heart rate monitor or cycle computer to sync right without interference knows how that can help make a work out all the more enjoyable.
