An Opportunistic Coexistence Analysis of LTE and Wi-Fi in Unlicensed 5 GHz Frequency Band

Current and future cellular networks are expected to deliver increased data performance to meet increasingly exponential customer needs. Because of the heterogeneity of future devices and technologies available today, high quality and efficient communication is the challenge for LTE networks. The licensed bandwidth of LTE is used according to standard rules. The unlicensed bandwidth to handle network traffic must expand its bandwidth and increase the data rates. The 5 GHz unlicensed band is most effective and suitable. However, this 5 GHz band has Wi-Fi and frequency coordination of both LTE and Wi-Fi networks during sharing of spectrum. Here the spectrum is shared among the LTE and WiFi network and access 5 GHz unlicensed band. In particular, it affects Wi-Fi performance through downlink transmission of LTE. In this research article, an experimental findings and analysis in 5 GHz frequency spectrum, presented that LTE affects the performance of the Wireless Fidelity network and that to achieve optimal coexistence, a true frequency difference must be maintained.
