An Alytical Study Of Cellular Networks LTE-U and Wi-Fi in 5G Environment
Year: 2025
Type: article
Abstract: The coexistence of LTE-U and Wi-Fi exists and a study proposed a Wi-Fi and LTE-U MAC design that performs better than traditional design. Mobile carriers have begun restructuring their set-ups to discharge their stream of traffic flow in unlicensed bands as a result of sharp growth in mobile traffic. Utilizing the radio resources for operators' transmissions, the new 3GPP technologiesLAA and LTE-U operate over the 5 GHz unlicensed spectrum using an unlicensed radio interface. Spectrum expansion via different radio interfaces, including LAA and LTE-U, is essential for 5G. To preserve a fair portion of the unlicensed spectrum, Wi-Fi performance is significantly impacted by the physical and MAC layer schemes for LTE-based systems. The coexistence technique suggested in this article controls back off for LTE-U and Wi-Fi when they reach the 5 GHz bands. The new method distributes a set number of packets to both technologies through a new interface located in a heterogeneous cloud RAN. Future fifth-generation (5G) cellular networks will be designed entirely differently as a result of new research paths. The five technologies covered in this article as device-centric designs, massive MIMO, smarter devices, millimeter waves, and native support for machine-to-machinecommunications could result in disruptive design modifications to both the architecture and the components. Each technology's essential concepts are presented, along with how they might affect 5G and the lingering research problems. In the future, practically implement the coexistence of LTE-U and Wi-Fi using the novel H-CRAN paradigm.
