Analyzing all the best tech conferences and meetings helped us throw a great 5G party   The tables were turned on this well-documented “5G Symposium Critic” last month. This began last spring, when I am sure I visibly flinched when our group president said, “Let’s have a 5G Summit!”   Despite the risks of having YA5GE (Yet Another 5G Event), I… (Show more)
The previous blog post discussed NB-IoT, and why, although it is a great IoT wireless solution that leverages massive infrastructure and technical momentum, it may not be the best choice in certain locations or in applications that demand great flexibility.   There are three more situations where other LPWAN technologies may be superior. These… (Show more)
As 3GPP moves from LTE to LTE-Advanced Pro to New Radio, MIMO continues to increase in strategic importance, adding implementation complexity and more specifically, channel count.  MIMO has moved from 2 streams to 8 streams with a small one-dimensional antenna, to “full-dimension” (FD-MIMO, 8 streams radiated through a 64-element array with… (Show more)
The NB-IoT LPWAN radio technology is a great solution for many IoT applications because it leverages long-proven cellular radio technology and infrastructure that is supported by numerous cellular providers worldwide. Furthermore, NB-IoT has good security, and it is an LTE specification from 3GPP, which gives it substantial technical momentum for… (Show more)
The emergence of 5G mobile communications is set to revolutionize everything we know about the design, testing, and operation of cellular systems. The industry goal to deploy 5G in the 2020 timeframe demands mmWave over-the-air (OTA) test solutions and requirements in little more than half the time taken to develop the basic 4G MIMO OTA test… (Show more)

My experience with broadcast TV in 1960’s Colorado was fraught with “ghost” images that distorted our television screen during episodes of my favorite TV programs. My parents’ explanation of this being an “echo” from the mountains was very confusing. How could light have an echo? It was in my early days at Hewlett-Packard that I learned the… (Show more)
