By Anne Fisher and Luc Darmon – Earlier attempts to accomplish precise location used methods based on measuring the RF power at a point in space and assuming a correlation between the electromagnetic field and distance to the access point.
This method requires a lot of “fingerprinting” work because you have to measure the field in many areas of the room so that you build a 3D matrix of the field [thus allowing you to] correlate with the distance. But [with the method just described] there are a number of drawbacks. First, the precision is not there. Second, as soon as you have another person or another object in the room the fingerprinting is definitely wrong, and people have to find algorithmic ways to compensate, which are fairly heavy and power consuming.
For those transitioning from methods not based on Time-of-Flight to those based on Time-of-Flight and to using impulse radio ultra wide band (IR-UWB) to measure the signal’s time of flight, there are considerations related to the technology itself.
For example, if you measure the signal’s time of flight from one object to another object, if you have an obstruction like a wall or another person, you have to assume that signal is slowed down, so the distance displayed will be larger—so you have to architect your system in a way such that you take into consideration the elements of this new technology.
Now, though, people are past the point of questions such as “what is this new technology and how does it work?” I think the market now understands there is no way to do location precisely other than with IR-UWB.
The technology in the chip is very versatile in terms of configurations and architectures. One can do a lot of different things in different systems with it. It’s a building block that people can use for doing different things and different architectures. more> https://goo.gl/9rykVv

By Caroline Hayes – Whereas the Cortex-A5 has features designed for mobile computing, and the Cortex-A7’s multi-tasking suits smartphones, this latest processor is based on the ARMv8-A architecture.
It supports both 32- and 64-bit compute capabilities but consumes 10 percent less active power than the Cortex-A7.
Nandan Nayampally, VP Marketing, CPU Group, ARM, is looking forward to continued growth in the mobile phone market. The company has already shipped two billion entry-level smartphones, equipped with Cortex-A5 and Cortex-A7.
This eight-stage pipeline features 64-bit compute capabilities and a redesigned instruction fetch operation for efficiency with fewer cache accesses for lower power consumption. The instruction fetch bandwidth is optimized to accommodate the new branch prediction techniques. Throughput is also accelerated while minimizing area and power costs, using the instruction queue, which is balanced between the fetch and execute units. more> http://goo.gl/RVEaou

By Alan Grau  – There are a number of reasons that embedded security is hard. A few of the top challenges include:
- The low cost of attack
- The weakest link problem
- A lack of expertise and training
It’s very easy, when talking about cybersecurity, to focus on the various technical aspects of building a secure device.
Security is only as strong as its weakest link. As security is a system issue, not just a device issue, there is a very long chain of possible attack points that must be secured. more> http://goo.gl/6U1IHZ
By Ryan Radia – Unless the courts or Congress rein it in, the Federal Communications Commission (FCC) might soon transform itself into the Internet Regulation Commission.
To understand the FCC’s latest power grab, think back to 1996 — the year America Online introduced its unlimited dial-up service.
That’s the last time Congress rewrote federal telecom laws, albeit making barely any mention of the Internet. One new provision, Section 706, instructed the FCC and the states to use their powers to encourage the expansion of speedy Internet access and promote infrastructure investment.
This provision sounds simple enough, but as current FCC leadership sees it, the law is an invitation for potentially boundless regulation. more> http://goo.gl/JLFxo0
