Ericsson and the Federal University of Ceará (UFC) in Brasil have revealed headline details of the three 5G research projects they have been working on since 2012, including work on new spectrum bands, high density antennas and interference management.
The research is premised on the fact that with the proliferation of smartphones and tablets and the increasing demand for quality of service and user experience in external and internal environments, current networks —3G and 4G—will not be sufficient to meet users’ future needs and expectations.
In addition, new types of traffic and connections are expected, such as those arising from the Networked Society and the Internet of Things.
In the first quarter of this year, mobile data traffic exceeded the total mobile data traffic in 2011 and it is expected that the mobile data traffic in smartphones will grow 10 times from 2013 to 2019. Studies show that 5G is not just an extension of current LTE technology, but an integrated family of more complex technologies.
The main points of the research developed by Ericsson and the UFC will be the new spectrum bands (called ‘millimeter waves’, above 10GHz and up to 60GHz or more), systems with high density of antennas, interference management, communication between devices and use of small cells within the concept of heterogeneous networks.
The UFC is represented by the Research Group on Wireless Telecommunications (GTEL), a centre of excellence in research and development of technologies for wireless systems, featuring world-class laboratories, teachers and researchers.
At present, the group has about 40 people, including 8 doctorate professors, 24 researchers and 7 engineers. The partnership between the company and the university is based on three pillars: research, patents and standardisation.
Edvaldo Santos, director of innovation, Ericsson Brazil, said: “We have been working for 15 years with the UFC and this collaboration has resulted in significant contributions to the generation of knowledge for exploration and development of new technologies, which is reflected in national and international scientific publications, books and contributions to the establishment of standards and patents. The UFC is an important partner in building Ericsson’s technology leadership in 5G systems.”
UFC professor Dr. Rodrigo Cavalcanti said: “For the university, the satisfaction is the same. The partnership between the UFC and Ericsson is essential for the exchange of academic and technological knowledge that promotes the most advanced research on next-generation mobile themes relevant to the national and international industry.
“In addition, the University is very pleased to be able to count on Ericsson’s support in our students’ education, contributing with advanced laboratories, providing internships, encouraging graduate studies and bringing world leading technological know-how.”
