The official assertion stated, Operators are already utilizing fibre broadband networks for backhaul visitors, and this trial demonstrates that these similar networks can now be leveraged to fulfill the stringent capability and low latency calls for of fronthaul.
Addressing Connectivity Challenges in 5G Networks
As operators transition to 5G, they face the problem of deploying extra antennas to accommodate the sign propagation limitations of upper frequencies and guarantee optimum protection and capability. Fronthaul transmission serves as a significant hyperlink connecting these new small-cell antennas to the core community.
Small cells and fibre broadband networks typically have an analogous footprint, making fibre networks available to be used in 5G transport. The latest trial performed by CHT-TL validates the efficacy of 25G PON broadband expertise in assembly the necessities of cellular fronthaul, stated the assertion.
