CHALLENGE The main challenge was to replace leased-lines in order to provide more bandwith with higher availabilty parameters to the company's customers. Especially, as the leased-lines in rural regions were too expensive, provided insufficient bandwidth or did not correspond to the reliability requirements.

SOLUTION In early 2010 imos decided to deploy microwave links to connect customers directly to the backbone. The company first replaced an older 5Ghz link operating with Hamburg 40 Mbps with a license free 24Ghz CFIP Lumina link providing stable 366 Mbps full- duplex throughput. Compared to the 5Ghz link, the performance of CFIP Lumina was neither affected by harsh weather conditions nor by interferences with other license free 5Ghz equipment. Berlin Based on the positive experience with SAF, imos decided to significantly increase the Germany capacity and reliability of their backbone by deploying 11 further CFIP Lumina links and Köln one CFIP-108 link with throughput of up to 366 Mbps full-duplex. The links were installed between imos POPs and customers as a replacement for leased lines and 5Ghz links with typical bandwidth of 2-6 Mbps and lower reliability. The company is using sites such as water or castle towers or other high buildings as relay stations. In addition, imos Göppingen, Baden-Württemberg is using sites of their customers as POPs for further expansion of their network. Munchen Highlights & Benefits of CFIP- Lumina - Most up-to-date technology with up to 256QAM modulation and 56MHz channel bandwidth allows high capacity throughput up to 366 Mbps (per radio); -Optical Ethernet connections provide excellent protection against lightning strikes and allow long distances from user equipment to radio; -2 Gigabit Ethernet ports provide simple (management and user traffics on separate ports) and advanced configuration (various network protection schemes and topologies); -Up to 4094 concurrent VLAN traffic allows building many port-to-port networks paths for specific client services; -ACM (Adaptive Coding and Modulation) and ATPC (Automatic Transmit Power Control) for high availability and high density deployments; -Jumbo frame size supports up to 9728 bytes , which allows using longer header info (VLAN, MPLS) and transmitting more useful content and less headers, thus gaining on total throughput.
