5G Based Femto and Macro Cell Integration for Next Generation Mobile Communication

Abstract

newline The advent of modern wireless communication technologies opens the opportunities newline of various application scenarios. The two major problem areas are the non availability newline of broadband signal in the remote rural region for last mile connection and insufficient newline available throughput in the urban region to cater newly coming high data speed appli newlinecations. The first objective is to develop the models of broadband signal transmission newline integrating macro and femto cells for solving the problem of last mile connectivity. newline The second objective is to develop the models of enhanced mobile broadband connec newlinetivity using carrier aggregation at mmwave frequencies for addressing the problem of newline insufficient available throughput. A scheme of last mile connectivity for rural regions newline is suggested where 4G signal is relayed through 5G new radio (5G NR) waveform newline integrating the macro and femto cells. Another IAB based wireless network archi newlinetecture is suggested for last mile connectivity where carrier aggregation technique is newline used for throughput enhancement. In addition, a scheme of distributing broadband newline signals inside a home is suggested with the features like high speed internet, 4K video newline streaming, IoT controls etc. which makes it a smart model home. In the direction of newline performance improvement in terms of SNR, a scheme of digital beamforming based newline on the concept of spread spectrum technology using orthogonal Fourier codes is sug newlinegested for 5G receiver which achieves reduced cost, size, weight and power of the newline receiver. Propagation of 5G NR signal in the 60 GHz band is studied rigorously for newline small cell scenarios which shows the achievement of very high throughput using the newline huge bandwidth available in this high frequency band. In order to examine the vi newlineability of vehicle to vehicle (V2V) communication by using 5G signals, the wireless newline communication with 5G NR signal between two vehicles are studied comprehensively newline for both the static and moving conditions considering audio-video and safety infor newlinemation
