While the industry conferences focus on small cells, there is another type of in-building wireless coverage which is quietly rolling out and taking care of capacity and coverage issues. Distributed Antenna Systems are becoming big business, with a global growth rate of 20 percent this year, and higher numbers in key markets like North America.
The market for consumer femtocells has not taken off as many people hoped. Shipments of consumer femtocell units will reach 2.1 million this year, barely exceeding numbers in 2012 and 2011.
