Open RAN standard increases flexibility and performance

News | February 27, 2020

Hardware becomes software – the production model of the telecommunications industry is facing a radical change. More and more network functionalities are decoupled from hardware. The networks of the future are open to software partners, more intelligent and adapt flexibly to new requirements.

In the development of new technologies, Deutsche Telekom has reached another milestone together with its partners VMware and Intel: the development of a so-called virtual RAN platform (vRAN) based on the Open RAN standard (O-RAN). RAN is the abbreviation for “Radio Access Network” and refers to antenna technology components in mobile communications. The new platform increases flexibility for LTE and 5G networks. At the same time, it makes the technical infrastructure independent of specific hardware. The solution is currently undergoing extensive laboratory testing.

The new virtual radio network architecture is based on software and cloud solutions with open standards and interfaces. This makes it possible for the first time to use optimization software for the wireless network. The first tests show: This software doubles the efficiency of an LTE radio network. In addition, the software-based platform is scalable. For example, if the number of antennas is increased from two to four, the efficiency of the virtual RAN is also doubled.
