Delivering indoor connectivity has long dogged mobile network operators (MNOs). Whether it be the location of a building or the construction materials used, it is frequently difficult for mobile subscribers to get a reliable wireless signal from the MNO towers located outdoors. High-bandwidth wireless spectrum, used by many MNOs for the latest in high-speed connectivity services, does not penetrate buildings easily and has limited coverage range, leading to a mixed and frustrating experience indoors.
Over the past several years, MNOs have tackled the problem of indoor wireless connectivity by deploying distributed antenna systems (DAS) in places where large amounts of people congregate, including venues such as stadiums, convention centers, airports, major hotels, among others.
