CST Global’s 60GHz ROF shows the way to future 5G-solutions

Sivers IMA Holdings AB subsidiary, CST Global, has successfully proven the feasibility of 60GHz Radio over Fiber (ROF) transmission, at a 1270nm wavelength. ROF networks are emerging as a completely new and promising communication paradigm for delivering broadband wireless access services and fronthaul at 60 GHz, relying on the synergy between fixed optical and millimeter wave (mmWave) technologies. CST Global’s research shows that their 60GHz, ROF, broadband solution is feasible, by combining CST Global’s optical solutions and mmWave technology from Sivers IMA in the future.

The feasibility comes as part of CST Global’s involvement in two, funded research projects. iBROW, an EU Horizon 2020 project, which started in January 2015 and WiPhi, an Innovate UK project, which started in January 2018. The feasibility at a 1270nm wavelength can now be added to 1310nm, which was previously shown as an effective transmission wavelength. CST Global is confident that the technology will also be feasible at 1550nm, which can be used for extended transmission distances of up to 25km.

“ROF is a very cost-effective solution, which supports 10s of kilometres of fiber connection from a Remote Radio Head to a centralized radio access base band unit pool in 5G networks. CST Global has now proven the feasibility of the 60GHz ROF transmission, which is highly supportive of the CST Global and Sivers IMA joint efforts to optimise a combined ROF, optical and mmWave solution for future 5G networks. Although more development work is needed, I see CST Global’s achievement as confirmation that we are on track to establish a commercially viable solutions in this area”, comments Anders Storm, CEO of Sivers IMA Holding AB.

CST Global is a Glasgow-based, wholly-owned subsidiary of Sivers IMA Holding and the UK’s leading, independent, III-V opto-electronic, semi-conductor foundry.
