Mobile has revolutionized computing and the internet. So, what is next for mobile services? Proximal discovery is empowering the next generation of mobile services, creating a digital 6th sense through always-on awareness of friends, services, events, and other relevant value in one’s proximity. LTE Direct is an innovative device-to-device technology for proximal discovery that is required to scale up from today's existing location-based and proximity beacon solutions. LTE Direct is creating a digital 6th sense by providing privacy sensitive and battery efficient discovery of 1000s of devices in ~500m proximity.
