Cell phones to operate underground

Cell phones do not work on tunels and other undeground contructions without help because many meters of earth, stone, concrete and steel to block the RF signals. To make cell phones to work underground, you need to build some sort of structure that allows signals to pass through so you can access your wireless data.

Part of the problem is that 5G is not one proposed standard, it’s a growing set of them.  Every new proposal of this sort complicates the ability of standards bodies

Using a supercapacitor for power management and energy storage in IoT

http://www.edn.com/design/power-management/4458294/Using-a-supercapacitor-for-power-management-and-energy-storage-with-a-small-solar-cell–Part-1 The environment has abundant energy but little power. Energy harvesting can tap the environment’s “infinite” source of energy, and avoids the cost of wiring to mains power or replacing of batteries. This article will look at using small solar cells.  Depending on the light level, whether indoors or out, small solar cells may deliver
