Bristol academics invited to speak at major 5G summit

Channel measurement and modelling: Bristol's perspective on an endless quest

2014-04-16
(Press-News.org) For more than 20 years academics from the University of Bristol have played a key role in the development of wireless communications. In particular, they have contributed to the development of today's Wi-Fi and cellular standards. Two Bristol engineers, who are leaders in this field, have been invited to a meeting of technology leaders to discuss the future of wireless communications. The first "Brooklyn 5G Summit" will be held next week [April 23-25] in New York, USA.

Andrew Nix, Professor of Wireless Communication Systems and Mark Beach, Professor of Radio Systems Engineering in the Department of Electrical and Electronic Engineering will represent the University and the UK at the international event.

Fifteen years ago global research began to unlock the benefits of antenna sectorisation and smart antenna solutions. At Bristol, the Communication Systems and Networks Group began work on the TSUNAMI (Technology in Smart antennas for UNiversal Advanced Mobile Infrastructure) series of EU projects. This included spatial channel characterisation and the construction of Space Division Multiple Access (SDMA) demonstrators.

The introduction of multiple-input multiple-output (MIMO) signal processing heralded the introduction of numerous new models and measurement techniques. It became necessary to analyse the time dynamic structure of the matrix channel and its relationship with multipath spread and transmit/receive array geometry. Bristol's ray tracing models were enhanced to support 3D polarimetric antenna patterns and operation in picocells, as well as macrocells.

Professors Andrew Nix and Mark Beach said: "At the summit we will explore the challenges introduced by 5G+ network designs. The rise of data traffic growth will see disruptive new technologies emerging in the mmWave bands (60-90GHz). Smart antennas for backhaul and mobile access are now required to overcome the challenges of path loss and dynamic shadowing.

"We have entered a new phase of channel measurement and modelling. The race is now on to characterise urban mmWave channels and to use the resulting data to develop efficient 5G networks by 2020."

Today the interest in 3D channel models has intensified. In the quest to maximise capacity, new systems are looking to exploit both the azimuth and elevation domains, especially in small cells. In partnership with NSN, Bristol's latest ray tracer, which models every building and tree over 150 square kilometres of London, has helped define the structure and parameters of the new 3GPP 3D channel model. This model is being used within the industry to quantify transformational technologies such as 3D beamforming and massive MIMO.

Researchers question emergency water treatment guidelines

2014-04-16
The Environmental Protection Agency's (EPA's) recommendations for treating water after a natural disaster or other emergencies call for more chlorine bleach than is necessary to kill disease-causing pathogens and are often impractical to carry out, a new study has found. The authors of the report, which appears in the ACS journal Environmental Science & Technology, suggest that the agency review and revise its guidelines. Daniele Lantagne, who was at the Centers for Disease Control and Prevention (CDC) at the time of the study and is now at Tufts University, and colleagues ...

Relieving electric vehicle range anxiety with improved batteries

Relieving electric vehicle range anxiety with improved batteries
2014-04-16
RICHLAND, Wash. – Electric vehicles could travel farther and more renewable energy could be stored with lithium-sulfur batteries that use a unique powdery nanomaterial. Researchers added the powder, a kind of nanomaterial called a metal organic framework, to the battery's cathode to capture problematic polysulfides that usually cause lithium-sulfur batteries to fail after a few charges. A paper describing the material and its performance was published online April 4 in the American Chemical Society journal Nano Letters. "Lithium-sulfur batteries have the potential to ...

Breakthrough points to new drugs from nature

2014-04-16
Researchers at Griffith University's Eskitis Institute have developed a new technique for discovering natural compounds which could form the basis of novel therapeutic drugs. The corresponding author, Professor Ronald Quinn AM said testing the new process on a marine sponge had delivered not only confirmation that the system is effective, but also a potential lead in the fight against Parkinson's disease. "We have found a new screening method which allows us to identify novel molecules drawn from nature to test for biological activity," Professor Quinn said. "As it ...

Researchers propose network-based evaluation tool to assess relief operations feasibility
2014-04-16
The United Nations Office for Disaster Risk Reduction reported that disasters have affected around 2.9 billion people worldwide from 2000-2012— killing more than a million, and damaging around 1.7 trillion US dollars in estimates. Moreover, natural disasters and their damages have been documented to occur with increasing intensity. Given the staggering numbers, effective disaster preparedness and relief response plans is compelling, especially considering the fact that natural disasters are usually unpredictable and damage cannot be avoided. Implementing a speedy and ...

Medieval slave trade routes in Eastern Europe extended from Finland and the Baltic Countries to Asia

2014-04-16
The routes of slave trade in Eastern Europe in the medieval and pre-modern period extended all the way to the Caspian Sea and Central Asia. A recent study completed at the University of Eastern Finland suggests that persons captured during raids into areas which today constitute parts of Finland, the Russian Karelia and the Baltic Countries ended up being sold on these remote trade routes. There was a particular demand for blonde girls and boys who were seen as exotic luxury items, and it was financially beneficial to transport them to the far-away markets. The study by ...

Study provides new insight into how toddlers learn verbs

2014-04-16
Parents can help toddlers' language skills by showing them a variety of examples of different actions, according to new research from the University of Liverpool. Previous research has shown that verbs pose particular difficulties to toddlers as they refer to actions rather than objects, and actions are often different each time a child sees them. To find out more about this area of child language, University psychologists asked a group of toddlers to watch one of two short videos. They then examined whether watching a cartoon star repeat the same action, compared ...
