Is 5G a new update for 4G or a new technology
Over a century after Jagadish Chandra Bose invented radio communication, but saw Italian inventor Guglielmo Marconi walk away with the credit, he is set to get his due. The millimetre-wavelength frequency that Bose used in his experiment in 1895 is the foundation of 5G that scientists and technologists across the world are now trying to re-invent.

Wireless equipment control using MATLAB-based GUI
In process instrumentation and control, operators in the plant control room monitor on-field sensors and send real-time commands to control actuators and final control elements such as motors, pumps, variable-speed drives, variable-frequency drives and electrically operated valves in the field using a human-machine interface (HMI) program for process control. A graphical user interface (GUI)-based HMI application enhances the user-friendliness of such an approach.

Models of a linear feedback shift register using MODELSIM
Presented here is a linear-feedback shift register (LFSR) using Verilog that is designed and simulated using ModelSim testbench. Register-transfer level (RTL) models are quite popular in the industry as these can be easily synthesised using latest electronic design automation (EDA) tools. This project describes the RTL model of a synchronous circuit—an autonomous LFSR that executes concurrent transformations on a data path under the synchronising control of its input clock signal.

Getting started with NodeMCU development board for IoT
Since Internet of Things (IoT) projects are now quite popular, I recently bought a NodeMCU board to try IoT application development. The NodeMCU is an open source development board based on ESP8266EX microcontroller with integrated Wi-Fi transceiver. Uploading programs to NodeMCU from any computer via microUSB port is very easy as it supports several programing languages.

Which chip is the fastest
Intel launched its eighth-generation processors in August this year, but these weren’t the 10nm process chips most techies were looking for. The chipmaker had originally forecasted that it would have 10nm chips ready at the end of 2016, which is roughly two years after the launch of their 14nm process based chips as per the usual tick-tock cycle. But we all know hardware is hard, especially when it needs to be engineered and fabricated at the nanometre scale!

Teleoperating robots with virtual reality
A new virtual reality (VR) system from Massachusetts Institute of Technology (MIT) could make it easier for factory workers to telecommute. Developed by researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), the system lets users teleoperate a robot using an Oculus Rift headset. It embeds the user in a VR control room with multiple sensor displays, making it feel like they’re inside the robot’s head.

The Indian test & measurement industry outlook
With the increasing complexity of electronic gadgets, testing has become imperative at every stage of product life-cycle. Test and measurement (T&M) systems play a critical role in ratifying the performance of a wide range of electronic products. These are used across the entire product life-cycle, starting from the product design and development phase, to production testing, pre- and post-market testing, as well as support. Thus, T&M and electronics industries grow hand-in-hand.
