LTE Direct uses radio signals—called ‘expressions’—which can be private and discreet (targeted securely for certain audiences only) or public (transmitted so that any application can receive them). Public expressions are a common language available to any application to discover each other, and this is the door to consumer utility and adoption. Public expressions exponentially expand the field of value. For example, someone using Facebook to monitor for ‘photography’ may find a new exhibit opening (broadcast via Yelp), an SVP of photography at ESPN (broadcast via LinkedIn), or another photography expert (broadcast via Twitter). Public expressions combine all applications—all value—into one single network, thereby expanding the utility of the system.
Mobile operators would be the spectrum holders for LTE Direct, and as such will be authorizing and controlling access to the system. Any application seeking to equip itself with LTE Direct must work with the mobile operator. Thus, this is an excellent opportunity for mobile operators However, its important to note that LTE Direct offers value and opportunities to the entire eco-system including app developers, infra-structure providers, OEMs, system integrators and the various verticals that can translate the platform to meaningful utility for the end consumers.
