Kathrein has announced an innovative solution to meet the growing demand for mobile data traffic in buildings and across campus-wide environments. The German-based antenna and electronics manufacturer has developed a new Micro C-RAN system called K-BOW that will be launched at this month’s Mobile World Congress in Barcelona (Hall 06, Stand J36).

Kathrein’s K-BOW system bridges the gap between established network architectures and those required to deliver future wireless service provision indoors and over mixed indoor/outdoor sites. K-BOW supports multi-operator, multi-band and multi-standard operation and uses the flexibility of a mobile communications capacity pool to dynamically meet changing demand for data. In this way, operators have the flexibility to adjust their in-building networks to meet customer requirements and react quickly to changes in user behaviour.

Remote adjustment to capacity demands

As changes to coverage and capacity can be done remotely and do not involve physical changes to the installation, Kathrein’s Micro C-RAN solution drastically reduces the cost and time for network operators. This contrasts to conventional static indoor cell architectures, which are very expensive to modify or upgrade.

K-BOW aggregates data traffic with a centralised RAN platform and transmits multiple combinations of signals to individual radio units (RUs). The solution is remotely-controlled over a network monitoring system so that capacity in any area within the building can be easily increased or decreased. This allows for the creation of self-organising networks (SONs) in buildings, while LTE MIMO can also be directly introduced to offer end user data rates equivalent to those outside of buildings.

Top signal quality at all times

“With mobile communications continuing to change dramatically, K-BOW is setting the standard for mobile data transmission in buildings by simultaneously overcoming multiple technological challenges,” stated Dr. Michael Weber, CTO at Kathrein. “We provide network operators with the flexibility they need to respond rapidly to their customers’ demands. We are opening up exciting new possibilities for indoor network optimisation, providing users with the best possible signal quality at all times.”

Energy expenses significantly decreased

K-BOW’s energy saving potential is particularly innovative. Signals from individual frequency bands can be switched on and off, based on demand from every small cell. Network operators can, for example, switch to a 1,800 MHz base signal at night, ensuring coverage provision within the building while saving electricity costs from the other amplifiers. This feature can reduce energy expenses of the entire system by up to 50 per cent.

“Most traditionally structured antenna systems have not been designed to save energy, despite this being a major cost factor in all companies,” explained Dr. Weber. “What’s more, users are placing totally new demands on the system’s flexibility, whether it is about response times to network changes, data rates or service level improvement.”

K-BOW offers an innovative, future-proof solution for in-building mobile communications challenges. The system will be introduced at the MWC in Barcelona and will then be made commercially available at the beginning of 2015.

Kathrein’s product division base station antennas and filters for mobile communications received an important prize at the “Vodafone Supplier Awards 2013”: Vodafone presented the “Outstanding delivery performance” category award to the Rosenheim antenna specialist company due to their consistent fulfillment of contractual requirements, continued outstanding delivery performance and customer focus.

As one of the world’s leading telecommunications companies with a significant presence in Europe, the Middle East, Africa and Asia-Pacific, Vodafone and their partner networks evaluate the performance of their suppliers and record the success of their collaboration in a bi-annual supplier performance report.

Awards are given in five different categories: outstanding and reliable delivery performance, outstanding commercial value and product development, responsible supplier regarding sustainability and health and safety, extraordinary contribution and last but not least supplier of the year. Vodafone considered their 46 essential main suppliers in the evaluation.

Together with Anton Kathrein, the team manager of the mobile communications sales team, Lars Goldstein, was delighted to accept the award from the Vodafone Procurement Company at the Technology Centre of Vodafone’s partner McLaren Mercedes in Woking, Surrey. Whilst expressing his gratitude towards his sales team, Mr. Goldstein didn’t forget to mention all his colleagues from the order coordination, planning, customer service and order processing departments: “Had it not been for this team effort in our day to day business, we would not have received this award!”

Moreover, Kathrein was once again nominated for the “Supplier of the Year Award”, and captured the outstanding 2nd place of 2013.

Dipl.-Ing. Lars Goldstein stated: “As long-time partner, Kathrein wants to be able to support Vodafone in the best possible manner and continue to cooperate flexibly and proactively”. First and foremost, the focus should be placed on the day-to-day contact between the employees of Kathrein’s global sales network and the Vodafone operating companies.
