Introducing LTE Direct

Posted on
Introduction

LTE Direct is a device-to-device platform that enables true “continuous” proximity based discovery. LTE Direct is a synchronous system operating in licensed spectrum under the control of the Mobile Service Provider, where devices monitor for service layer announcements (also known as expressions). The synchronous nature of the system allows devices to stay on for an extremely short duration to announce and monitor these announcements. This results in minimal battery drains enabling truly autonomous location discovery.

Untangling VoLTE

Let’s start with the fact that today’s environment are filled with devices that come from a variety of vendors. This makes life complex. Take, for example, the situation where two devices (each from different vendors) must communicate via voice over Evolved Packet Core (also by two different vendors) into an IP Multimedia Subsystem (from yet another vendor) and through an application server or two. See where I’m going here?

Respect Legacy

Legacy technology – you can’t escape it. Just when we thought next-gen communications had taken over, the Royal Birth proved us all wrong.
