Kathrein Takes Part in Successful Trial of the ORI Standard in the LTE Network


Kathrein has supported the testing of the world’s first LTE network that uses the standard ORI (Open Radio Equipment Interface).This standard makes components from different manufacturers compatible with each other on the same mobile site (the Base Band Unit of the base station and the Remote Radio Head). This trial was carried out successfully by the mobile phone provider Vodafone along with Kathrein and the Japanese technology group Fujitsu.

The LTE base station used in the functional test was fitted with RRH (Remote Radio Head) components from Kathrein as well as BBU (Base Band Unit) equipment from Fujitsu which conformed to the ORI release 1. The connection was made using fibre optic cable. “ORI is based on the existing interface CPRI and offers some benefits in comparison; these include increased interoperability, higher performance and lower testing effort,” said Burkhard Mann, Head of Software Development at Kathrein. In the long term, this reduces the costs in the telecommunications industry.

Through ORI, network operators are more flexible because they can use the BBU and RRH equipment of various service providers. Ultimately, this leads to more innovations in terms of performance and design for these key mobile communication components. The ORI standard already supports LTE Advanced and UMTS in Release 1 and will support GSM/GPRS systems and optimisation for C-RAN architectures from the Releases 3 and 4.
