Implications for the potential of Digital Dividend spectrum
Nokia Siemens Networks and Nokia say thay have jointly conducted the world’s first end-to-end LTE data call, using Nokia Siemens Networks’ commercial equipment, on the 800 MHz frequency band. The test is significat because 800MHz spectrum is being earmarked by operators as important to the deployment of rural mobile briadband.
The frequency band is gradually being freed up by regulators and assigned for mobile usage, although there are areas that still sit outside the GSMA’s vision of a trans-European harmonised spectrum policy.
The tests, conducted at Nokia Siemens Networks’ LTE Center of Competence in Espoo, Finland, follow the company’s commencement of production of LTE-ready Flexi Multiradio Base Stations for the 800 MHz band in April this year, and complement earlier tests with Nokia on the 2100 MHz and 2600 MHz bands.
The two companies demonstrated the end-to-end interoperability of Nokia Siemens Networks’ LTE network infrastructure with Nokia’s LTE-capable multi-mode multi-band Internet Modem RD-3. Infrastructure from Nokia Siemens Networks includes its Single RAN, featuring the Flexi Multiradio Base Station, the Evolved Packet Core comprising Flexi NS (Network Server) and Flexi NG (Network Gateway), and standard-compliant software.
“These tests are part of a larger campaign which includes various customer trials and demonstrations to make LTE on 800 MHz commercially viable by this summer,” added Reino Tammela, head of LTE business line, Nokia Siemens Networks. “Right after the first Digital Dividend spectrum was assigned to operators in the spectrum auction in Germany in May, it was important that standard compliant LTE network products and LTE user devices for this band become commercially available. This will enable successful rapid LTE network rollouts allowing end users to experience high speed and high quality mobile broadband services in rural areas with a large variety of terminals.”
