Military firm demonstrates spray-on wifi booster

Is there anything more frustrating than the struggle to obtain a decent wireless signal on your smartphone or tablet?

This first world problem may just have a first world solution, by way of an aerosol spray to boost wifi transmission.

Anthony Sutera of military tech company Chamtech recently showcased just such a product at Google's Solve for X.

The company has designed a spray-on coating emitting particles that can both boost phone reception and turn practically anything into an antenna, from a tree to a wall or strip of road.
