That's true Junko. But, recongize that technologies such as ANT+ are built into some mobile phone platforms (android) and tablets and can be used on an iPhone (with a dongle). And, ANT+ has an impressive build out of devices. Check this out: http://www.thisisant.com/consumer/ant-101/ant-in-phones/. According to its website, ANT has over three hundred certified platforms and 60+million installed nodes. Just had to get that out there. Bluetooth tends to get the most airplay, and, since low-power wireless is one of my 'things,' I felt the need to share.
@rbv, perhaps you are right. I get what you're saying.
But if you put yourself in the automotive industry's shoe, you do want to find a way to upgrade your cars with more features, rather than giving all that opportunities for added value to the mobile handset.
True!! Mobile devices in the recent past (may be after the Apple & Android revolution?) has started driving the world, be it the automotive electronics, medical electronics, industrial electronics domain. As people will be playing with their mobile devices interfacing with the in-car infotainment devices wirelessly, automotive designer might have challenging time in designing the electronics system controlling the car, that takes care of the safety of the passengers, more rugged and EMI hardened.
If it takes you 5 years to bring an infotainment system to market, you're doing it wrong.
This suggests that people are thinking of wireless connectivity as part of the car. It's not, or shouldn't be. It's part of the infotainment module which rides inside the car, and it should be possible, through good interface design, for the customer to select an infotainment upgrade whose design phase extended well after the car was manufactured.
Even rear-view cameras shouldn't need to be deeply integrated into the automotive system, at least not electronically. They need mechanical integration but electrically just power feed and a coaxial video cable. Ditto for back-seat displays -- pick a standard like DisplayPort and let a brand-new multimedia system be plugged into it at the dealer.
Aftermarket radios are a long-standing tradition. Perhaps instead of trying to cut them out by limiting consumer options, the manufacturers should embrace the idea and provide their own upgrades. Using wireless technology that's 6 months, not 6 years, old.
Your point about space not being limited is well made. The other thing to consider is that Bluetooth LE is not the only "kid on the block" for short range, low power connections. Although, with the muscle of the Bluetooth SIG behind it, it may mow over some earlier technologies that already have a respectable product base.
What intrgued me most in researching this story was when I've come to the following realization:
What connectivity technology choices carmakers make these days is totally driven by the mobile industry. In other words, the automotive industry no longer seems to have the luxury of thinking long and hard, and then coming up with automotive specific connectivity standards any more. They are truly more worried about keeping up with mobile devices drivers and passengers are bringing to their cars.
Who would have thought that this will be happening to carmakers 10 years ago?
I agree Yunko, getting low power bluetooth makese sense...if I were a car maker I would stick as many IO standard as possible and have an option to configure them as needed...low cost Wifi, extra $ for Bluetooth, top dollars for everything etc...but not nessasarily in one chip, in one board maybe
@krisi, true. But precisely because the car will be driven for 10 or 20 years, maybe it makes sense to look ahead and integrate Bluetooth Low Energy -- for which we may not see an immedate "apparent" market right now, but who knows, that may become a big market 10 years from now.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
