Abstract-Recently, there has been a substantial growth in mobile data traffic due to the widespread of data hungry devices such as smart handsets and laptops. This has encouraged researchers and system designers to develop a further efficient network design. The objective of this paper is to overview the technologies that can support multi Gbps for future Fifth Generation (5G) network. This paper presents many challenges, problems and questions that arise in research and design stage. It concluded that the anticipated high traffic demands and low latency requirements stemmed from the Internet of Things (IoT) and Machine to Machine Communications (M2M) can only be met with radical changes to the network paradigm such as harnessing millimetre-wave band in dense deployment of smallcells. Future wireless system will include all types of smart features and applications that make 5G the most intelligent and dominant wireless technology.

“…It is widely accepted that mm-wave need to be used with very limited cell radius <200 m, to minimize high pathloss at this band (by bringing the access point closer to the user). Fortunately, this action fits well with the dense deployment of smallcell which will be the trend of next generation mobile system [15]. As per our model, smallcell with high order sectorisation is considered as shown in fig.1 (a); the coverage of smallcell area is divided equally by the HOS.…”

Abstract-The fifth Generation (5G) mobile network will provide services with extreme data rate and latency demands compared to current cellular network, and provide massive capacity and connectivity to multitude of devices with diverse requirements and applications. Therefore, it is important to utilise all network resources to provide the 5G vision. In this paper, performance evaluations and impact of higher order horizontal sectorisation on next generation 5G mobile access is presented. The study has been focused on busy urban areas in high carrier frequency. Millimetre wave band has precious wide unexploited bandwidth that can be harnessed for mobile communication. The results for these scenarios show that higher-order horizontal sectorisation in millimetre wave based smallcell deployment can significantly increase the network capacity to meet the future requirement of 5G network, and provide high data rate and connectivity to huge number of devices. Moreover, beamforming can highly increase the data rate by efficiently increase signal power and suppress interference from unwanted directions.Index Terms -5G network, millimetre wave, network densification, higher order sectorisation, beamforming.

Abstract:In the Fifth Generation (5G) wireless standard, the Internet of Things (IoT) will interconnect billions of Machine Type Communications (MTC) devices. Fixed and mobile wearable devices and sensors are expected to contribute to the majority of IoT traffic. MTC device mobility has been considered with three speeds, namely zero (fixed) and medium and high speeds of 30 and 100 kmph. Different values for device mobility are used to simulate the impact of device mobility on MTC traffic. This work demonstrates the gain of using distributed antennas on MTC traffic in terms of spectral efficiency and fairness among MTC devices, which affects the number of devices that can be successfully connected. The mutual use of Distributed Base Stations (DBS) with Remote Radio Units (RRU) and the adoption of the millimetre wave band, particularly in the 26 GHz range, have been considered the key enabling technologies for addressing MTC traffic growth. An algorithm has been set to schedule this type of traffic and to show whether MTC devices completed their traffic upload or failed to reach the margin. The gains of the new architecture have been demonstrated in terms of spectral efficiency, data throughput and the fairness index.
