ABI Research (www.abiresearch.com) expects the market for in-building wireless equipment and deployments to grow to over US$8 billion in 2019, up from a forecast $4.4 billion for 2014 representing a 14% compound annual growth rate (CAGR).

North America will continue to be the region with maximum DAS spend with sports venues and transportation continuing to be the verticals which attract the most DAS investment while shopping malls, healthcare and hotels/resorts finish a close second place, according to the research group. Together these verticals in North America account for about two-thirds of DAS spending. North America is followed by Asia-Pacific and then Europe (in that order) for market size.

"While the Asia-Pacific region today accounts for less than a quarter of the total market, we expect it to grow to more than 25% by 2019 at a CAGR of more than 20%," says Nick Marshall, principal analyst at ABI Research. "Also Active DAS systems will continue to account for the majority of deployment types with over 60% of the revenue throughout our forecast period."
