Stadtwerke Rüsselsheim chooses KEYMILE technology

14. June 2014

Stadtwerke Rüsselsheim is investing in the future and creating a cutting-edge optical fibre network. It will deliver download speeds of 250 Mbps and upload speeds of up to 50 Mbps. KEYMILE's MileGate, the IP-based multi-service access platform, lies at the core of this ultra-fast broadband network.

Stadtwerke Rüsselsheim is offering optical fibre to the home, making it one of the pioneers in the German state of Hesse. The programme started after a unanimous resolution taken by the town council in December 2012 to appoint the utility to lay and operate an optical fibre network in Rüsselsheim. The first milestone was reached at the end of 2013 already. When selecting the technological framework for connecting optical fibre to homes and industrial buildings, utility managers chose KEYMILE's IP-based multi-service access platform MileGate. Flexibility, compact design and a high level of reliability are some of the MileGate platform's key characteristics.

The utility uses the mini IP-DSLAM MileGate 2011 as an access node for buildings with up to 24 homes. With its compact body, MileGate 2011 has been designed for basements or plant rooms in multi-apartment buildings. MileGate 2011 terminates the optical fibre in the building and transforms the signals the fibre has transmitted into electrical ones. MileGate 2011 can also receive an analogue and digital cable TV signal fed in via optical fibre and transmit it into the building's existing coaxial cables. As a result, network operators like Stadtwerke Rüsselsheim can offer traditional cable television and modern IPTV services at the same time.

Stadtwerke Rüsselsheim uses the MileGate 2200 and VDSL2 line cards to connect more than 24 homes. Because it is just two height units tall, MileGate 2200 is ideal when space is at a premium. Due to MileGate, the utility can offer residential customers super-fast Internet access, high-definition television and VoIP.

By the spring of this year, the utility had laid 25 kilometres of optical fibre in the town and connected around 250 buildings with a total of 3,000 homes and business units to the network. A further 1,500 are to follow by the end of the year. Following a partnership with the municipal housing-construction service provider gewobau, tenants in various residential units can now obtain fast Internet.

To date, the utility has invested about 2.3 million euros, with a further 2.5 million euros to follow by the end of this year. The utility is involved in all three levels of value creation – in building and operating the infrastructure, as well as marketing the telecommunications services via the network. The objective is to supply the whole of Rüsselsheim with optical fibre by 2020 at the latest. Consequently, investments worth 40 million euros in total are required, 30 million of which are not official subsidies and are covered by a federal state guarantee from WIBank (Wirtschafts- und Infrastrukturbank) Hessen. Therefore, the project has full long-term funding. In the future, the goal is to operate the optical fibre network in Rüsselsheim as an open-access network where other service providers also receive access to the optical fibre as a transmission medium.

"The ambitious programme to lay optical fibre into every home makes Stadtwerke Rüsselsheim one of Hesse's pioneers", explains Thorsten Mossmann, divisional head of telecommunications at Stadtwerke Rüsselsheim. "With KEYMILE as the technology partner, we can offer a one-stop solution, from broadband connection to television in HD quality to advanced telephony. It has proved to be an excellent idea to work with a German supplier that stands apart for its quick decision-making capabilities and highly professional technical support on all issues".
