Network providers and users have just gotten fourth-generation (4G) wireless under their belts, and already 5G wireless is on the horizon. It comes not a moment too soon as demand explodes for wireless devices such as smart phones and bandwidth-hungry applications. Experts say that by the end of the decade the disjointed and narrow bands of spectrum now devoted to wireless will be saturated and further growth will be impossible. Cisco Systems predicts that 25 billion wireless devices will be connected by 2015 and 50 billion by 2020, an average of more than six per person worldwide.
