Location-sensitive transmitters -- called "beacons" -- can send targeted advertising messages to smartphones and mobile devices based on their precise indoor location (for example, in the cereal aisle of a super market or the jeans department of a clothing store). Beacons are a reality and represent the future of shopper marketing, but they may also cause a big headache (see more about this below). Beacons are just one more technological advance in mobile and out-of-home communications that marketers, retailers, agencies and media sellers need to understand and build into their business models.
