News: UAVs and LTE

Drones, 3D printers and Mobile Internet are associated with the latest technology development. For a long time computers were providing us only with virtual values. They allowed us to learn, entertain, communicate, but they hardly ever created anything what we could really touch. That is about to change. It will take some time for sure, there will be a lot of disappointment, but at the end of the day I’m quite sure IoT, Drones and 3D printers will have even a bigger impact on our lives than the mobile phones have now.

You probably remember the first news about the Amazon Delivery using Drones/Unmanned Aerial Vehicle (UAV) back in 2013. Since then this industry has skyrocketed. Sure that brings also some challenges. An interesting fact is, that LTE can help to overcome some of them.

IMS Presence Illustrated: Beginners Guide

Presence sharing is a very important functionality when it comes to Rich Communication. We know it from many communicators such as Skype, Google Hangout, Facebook, Jabber, etc. But maybe you noticed that each of these applications has a different set of statuses, allows to share a different type of hard-state data (e.g. avatar, idea of the the day, web link ..). Mobile operators require some more unified approach as a particular status should be interpreted in the same way in all the networks (‘busy’ should have the same meaning in T-Mobile, Vodafone, or any other network).

That’s why Open Mobile Alliance (OMA) standardized Presence sharing for RCS using SIMPLE – Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (see http://technical.openmobilealliance.org/Technical/technical-information/release-program/historic-releases/presence-simple-v2-0). But that can be quite confusing, as the presence system is not simple at all. It is very complex and sometimes a bit difficult to grasp.

Let’s start from the beginning – what is the presence?
