"SimpleLink CC2541 (dualmode Bluetooth)"

I think you mean SimpleLink CC2561/CC2564 rather than CC254x, as the latter is a BLE-only (or proprietary) solution, and has no SimpleLink family member (at least not yet).

Is BLE in a car credible?

I would have been a lot more skeptical if Bluetooth low energy (BLE) in a car was pitched on the basis of "consumers' growing appetite for opening the door of a car via their smartphones."

My discussion with TI was fascinating, I am now more convinced of it, simply because there is a lot of economic incentives on the part of automakers to go for BLE.

Are you also seeing the proliferation of BLE in automotive sector (beyond the control of infotainment systems)?

security issues of BLE in a car

Does anyone have any insight on the security issues of BLE, once it starts to get used for opening and closing a door of a car (windows, etc.)?

Is it even remotely a conceivable for some total strangers -- other than you and your family members -- open your car door while you are driving?

@Junko: according to [1] bluetooth can be hacked.

@alex_m1, it's funny because one of the industry analysts I was talking to me this morning also sent me this exact same article. I will be probing this issue further.

@junko: the question is - how does cracking bluetooth compares with breaking a regular electronic key fobs. a rough google search shows it possible.

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.
