start thinking about 5G wireless

People being immersed in smartphone technology right now as it is can allow people to cram as much data as they can into the wireless networks but soon enough the efficiency of the 4G networks will not be enough.

by 2012, industry analysts say the amount of cellular traffic created by smartphones and tablets will be dwarfed by the data generated from the world of connected "things." Shoes, watches, appliances, cars, thermostats and door locks will all be on the network.

That's a big problem for wireless carriers, which are hitting a point of diminishing returns on their network efficiency improvements. They're butting up against the limits of physics as they try to add capacity.
Whatever people do, they should be ready for a new type of networking.
