LAA specification work starting in 3GPP

People in the escalator_2

A global standard for Licensed Assisted Access is agreed to be included in Release-13, the next release of the LTE specifications by standardization organization 3GPP. Fair co-existence with other technologies operating in unlicensed spectrum is a fundamental design principle for LAA. Extensive investigations of how LAA can co-existence with itself and Wi-Fi systems have been done over the last 9 months within 3GPP. This together with a continued large industry interest has formed the basis to decide to start a work item. This blog post will give you some important details about the study and its results.

Release 14 – the start of 5G standardization

Argentina - Nightscape.tif_2

Release 14 will mark the start of 5G work in 3GPP. In addition to the continued LTE evolution, a new radio access technology will be standardized, and these two technologies together will form 5G radio access. In this blog post, I will shed some light on a number of the key areas – low latency communication, spectrum flexibility, machine type communication, multi-antenna and multi-site transmission techniques, and ultra-lean design – and how they can be part of the upcoming 5G work in 3GPP.

Network on the move

moving train_2

High speed trains is one essential transportation mode in modern society. As everywhere else, people expect good communication services also on board high speed trains. This is however not a trivial task, and current solutions tend to fail for various reasons. Now we have developed and validated a novel, two-hop solution for high speed trains, together with a research partner in Taiwan.

The increasing use of software in all aspects of our lives, e.g. banking, commerce, vehicles, health care and so on, makes software security an extremely important issue not only for IT systems but for the overall security of our lives. Continue reading

Transport, Radio and Cloud Orchestration with SDN

SDN blog

SDN was the main keyword when it came to optical networks and their control at the OFC 2015. Orchestrating resources across multiple layers and domains—as an important next step in introducing SDN to the networks—is specifically worth highlighting. In other words, multi-layer/multi-domain orchestration seems to have emerged as a major added value of SDN to the networks.

At the conference, we presented details behind our SDN-based multi-domain orchestration demonstrator as a Post-deadline paper. Continue reading
