Ericsson CEO and President Hans Vestberg discusses the company’s first-quarter report for 2013, looking at the facts behind the figures.

Requiring only half the bitrate of its predecessor, the new standard – HEVC or H.265 – will significantly reduce the need for bandwidth and expensive, limited spectrum. HEVC (H.265) will enable the launch of new video services and in particular ultra HD television (UHDTV).

Effective July 1, 2013, Peter Laurin is appointed Head of Ericsson’s Global Customer Unit Vodafone, reporting to Head of Region Western & Central Europe, Anders Runevad.

In this new Tech Talk, Maria Edvardsson from Ericsson Research looks at the evolution of LTE and describes six of the technical areas that we believe in for the evolution of LTE.

This paper presents the first receiver supporting non-contiguous intra-band and inter-band carrier aggregation, capable of receiving up to three 20 MHz LTE carriers simultaneously. The single-chip receiver implements a reconfigurable architecture in 65nm CMOS, occupies 14.8 mm2 and consumes 155mW and 435 mW when receiving one and three carriers, respectively.

The objective of this paper is to improve the knowledge on directional channel characteristics at the base station, particularly concerning elevation. For this purpose a channel measurement campaign has been performed. A powerful new method for super-resolution channel estimation has been used to get a detailed picture of the directional characteristics of the channel. This has further led to improved knowledge of when processes like diffraction over rooftops and/or specular reflections are important. The findings herein have been incorporated into a model for the elevation angle dispersion which is proposed as an extension to some commonly used directional channel models such as the ITU-IMT-Advanced model.
