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. →

They are an inexpensive way to make applications aware of their surroundings. With beacons no user action is required for an application to obtain the proximity information. When a smartphone enters the range of a beacon, →

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 →
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 →
