That's pretty impressive that they were able to fix the car without bringing it into the shop...I wonder how far they can go and just how much chipmakers stand to gain from connected cars.

Automobiles having smartphone inbuilt is something that is going to happen very soon or may be already happening. No one can stop that. There is a big market to that and I already see many of many friends considering smartphone as their lives and keep updating status when driving.

It makes mroe sense to me to connect the two rather than have an additional smartphone that comes with a car. It used to be, in the early days of the PC market, people thought there would be phones that came with PCs as one integrated device. The reality is people dont necessarily want a second cell phone and they'll likely already have purchased a phone before getting a car.

smartphone and connected cars

Connecting the dots of smartphones and cars is an easy part. The hard work of genuine integration -- which goes beyond the hype -- has only begun.

I suspect developing enough car-centric apps is going to be a challenge.

@Sheetal, carmakers have a lot of different use-case scenarios to consider. Assuming a driver is bringing his smartphone into a car, the first choice car companies need to make is whether to support in their car an iPhone or Android phone. 

And obviously, there is a third choice of embedded LTE connectivity right inside a car.

There were many announcements of car OEMs and cellular operators at CES.

As I talked to a Delphi executive, though, car OEMs are keenly aware that they need to support both iPhone and Android. (You don't want to alianate a customer just because your car doesn't have a place to plug your iPhone!) Delphi was showing off its connectivity box that exactly supports both.

I would agree about supporting all platforms, but you left out Windows. I would go further and say I would not want to see car makers alienate a customer because their carrier was also not supported. Hence, these AT&T partnerships worry me. I want to choose my own carrier and I'm pretty sure the rest of us do too.

Oh yes, there is a point on supporting all service providers. This is also something that needs attention.

So I may get LTE through my next car before I get it through my next smartphone!

@tpfj: Agreed. Car shopping is hard enough. I don't want to have decide among Android, iOS, Windows, AT&T and Verizon models!

This is a sign, to me, that these systems are very much in their infancy. For a while, they will need to be subsidized by carriers with big pockets. I don't anticipate this being a permanent thing. I can't see the future though, so I guess I'm just being hopeful that cars won't come with carrier lock-in forever.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
