Measuring Frequency Dependence Across 5G mmWave Bands (NIST)


New research paper from NIST, "Methodology for Measuring the Frequency Dependence of Multipath Channels Across the Millimeter-Wave Spectrum." Abstract "Millimeter-wave (mmWave) communications promise Gigabit/s data rates thanks to the availability of large swaths of bandwidth between 10–100 GHz. Although cellular operators prefer the lower portions of the spectrum due to popular belief ... » read more

A Decade At The Ceiling


This month marks the tenth anniversary of the introduction of the Intel Pentium 4 HT 570J, which had an advertised operating frequency of 3.8 GHz. It was manufactured in a 90nm process, had a VID voltage range of 1.2V-1.425V and was rated at 115W TDP. In a previous article, Power to Fly, we looked at the graph that I’m including again here below for reference. The microprocessor indu... » read more
