Missed opportunity

To me, using 2G for newly minted eCall box (to be rolled out in 2015) strikes as a huge missed opportunity. 

By investing in LTE, for example, like what GM is planning to do, there seems to be a variety of business opportunities for carmakers to mine. Am I wrong about that?

An educational video:

3G isn't totally secure but 2G allows the base station to tell the phone to turn off the security mechanisms and 2G devices by default trust *any* base station.

EU's eCall does not mandate which cellular connection the eCall box needs to use. 

So, it is a choice left to automakers.

Why is 2G less secure than 3G in eCall implementation? Could you please educate me on that? Thanks!

Not only is E-Call a massive waste of money, but if it is going to have 2G technology it won't be secure! It is now trivial to mess with 2G so I worry about the consequences.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
