More than 50 percent of mobile data sessions originate indoors, say researchers at the Yankee Group.
And since 40 percent to 60 percent of mobile operator operational expense is attributable to backhaul transmission costs, Jennifer Pigg, Yankee Group analyst, expects data offload solutions, ranging from femtocells to Wi-Fi, to be a growing area of interest.
Indeed, 60 carriers are in femto trials, with 13 commitments and nine commercial services already launched (AT&T, Vodafone, SFR, China Unicom, DoCoMo, SoftBank, Optimus, StarHub, Sprint and Verizon).
