Thu., Nov. 03, 2016 to Fri., Nov. 04, 2016 , Fraunhofer-Forum, Berlin
Since 2011 Björn Halvarsson has been a Researcher with Ericsson AB in Stockholm and is currently responsible for the measurement part of the testbed program within Ericsson AB (i.e., currently leading the 5G measurements performed with the Ericsson 5G testbed). This position is highly technical within telecom and involves research, data analysis, C programming, paper writing (best paper award ISAP 2012 and EuCNC 2016), technical presentations for customers, team leading, measurement planning etc.
From 2004-2010 Mr. Halvarsson was first a Research Assistant and then a PhD student at Uppsala University with teaching duties and responsibility for the process laboratory.
He holds a Master of Science degree in Engineering Physics with specialization in Systems Engineering and a PhD in Electrical Engineering with specialization in Automatic Control from Uppsala University, Sweden.
Mr. Halvarsson is a board member of Polar Drives AB, in Uppsala, Sweden
Ericsson 5G Testbed – Field Trial Results
A much higher demand of capacity and peak bitrates in cellular networks are expected already in the near future. The aim of the coming fifth generation cellular communication system (5G) is to address these increased demands. To do that, considerably larger bandwidths compared to what is in use in cellular technologies of today, are foreseen to be needed.
One way to access bandwidths of the required size is to target higher frequency bands up to and including millimeter wave frequencies (30-300 GHz). This also opens up for much smaller form factors of the antennas, thereby making it more attractive to deploy advanced multi-antenna technologies such as beamforming and spatial multiplexing.
Ericsson has developed a 5G test bed with the purpose of demonstrating important 5G Proof points such as operation at high frequency bands with wide bandwidths showing multiple Gbps peak-rates. Another purpose of the testbed is to be able to evaluate and assess propagation properties at high frequencies; to evaluate advanced concepts such as beamforming and beam tracking; to evaluate deployment strategies; to gain antenna and radio building practice.
Measurement results from the Ericsson 5G testbed operating at 15 GHz with 800 MHz bandwidth will be presented, including results demonstrating beam tracking and propagation properties.
