Nokia Siemens Networks is conducting end-to-end LTE interoperability testing with four leading device vendors across several frequency bands, including AWS, 700 MHz and 2100 MHz. The tests cover several steps in end-to-end network configuration based on commercial LTE hardware, including the Flexi Multiradio Base Station and the Evolved Packet Core, and standard compliant software.
Nokia Siemens Networks recently completed successful calls with end to end LTE network infrastructure and LTE terminals. The company said this milestone shows the interoperability of the Nokia Siemens Networks LTE radio and Flexi NS and Flexi NG evolved packet core network elements with real LTE terminals, and end to end compliancy with the LTE standard (3GPP March 09 baseline specifications). The end-to-end calls were conducted in Nokia Siemens Networks LTE center of competence in Dallas in close cooperation with research and development sites in Ulm and Oulu. Nokia Siemens Networks also recently announced having conducted the world’s first LTE call and handover using commercial base station and fully standard compliant software.
In addition, NSN noted that it has shipped LTE compatible Flexi Base Station hardware to over 100 operators, and deployed Direct Tunnel functionality, a precursor to Evolved Packet Core, in over 65 networks.
