I visited today IoT Security Workshop at Aalto University (at Espoo Finland). Here are some slides from seminar →

https://www.technologyreview.com/s/608797/are-there-optical-communication-channels-in-our-brains/ Here’s an interesting question: are there optical communication channels in the brain? This may be a radical suggestion but one for which there is more than a little evidence to think it is worth pursuing. →

Ericsson, Qualcomm, and Verizon claim to be the first to have achieved 1 Gbps using commercial silicon and commercial infrastructure.  →

I have created a new category for 5G telecommunications technology topics. New postings related to 5G technologies will be posted under this category. I have also tried to tag older postings related to 5G to this 5G category. 5th generation mobile networks or 5th generation wireless systems, abbreviated 5G, are the proposed next telecommunications standards →

https://opensource.com/article/17/9/what-edge-computing?sc_cid=7016000000127ECAAY Edge computing is poised to boost the next generation of IoT technology into the mainstream. Here’s how it works with the cloud to benefit business operations in all industries There is much speculation about edge replacing cloud, and in some cases, it may do so. However, in many situations, the two have a symbiotic →

Using the wide band characteristics of SDR radios, it is possible replicate some of the functionality of much more expensive equipment such as a vector network analyzer.  Actually what SDR can do it scalar network analyzer functionality. A scalar network analyzer can measure amplitude, but a vector network analyzer can measure amplitude and phase and →

Here is teardown of one cell phone repeater device →

Here is picture of huge electrical switching device I saw today. I believe it is going to be installed inside or next to a big data center. I belive that this is made for controlling several megawatts of three phase 110 kV power. It seems to be made by ABB. →

https://www.recode.net/2017/9/1/16236506/tech-amazon-apple-gdp-spending-productivity Tech companies lead top U.S. companies in R&D spending. Amazon is No. 1. That’s notable because spending on research and development is a key indicator for U.S. productivity, a measure of how well our economy is doing, and productivity has been decreasing lately. Amazon, Alphabet, Intel, Microsoft and Apple, tech companies spent more on research →
