Finally, the performance of LTEAdvanced using IMT-A scenarios is presented and compared against IMT-A targets for full buffer and bursty traffic model. This includes bandwidth extension via carrier aggregation to support deployment bandwidths up to 100 MHz, downlink spatial multiplexing including single-cell multi-user multiple-input multiple-output transmission and coordinated multi point transmission, uplink spatial multiplexing including extension to four-layer MIMO, and heterogeneous networks with emphasis on Type 1 and Type 2 relays. In this article an overview of the techniques being considered for LTE Release 10 (aka LTEAdvanced) is discussed. It may also be noted that LTE Release 9 provides some minor enhancement to LTE Release 8 with respect to the air interface, and includes features like dual-layer beamforming and time-difference- of-arrival-based location techniques. The LTE-Advanced features enable one to meet or exceed IMT-Advanced requirements. Additionally, LTE Release 10 will support heterogeneous deployments where low-power nodes comprising picocells, femtocells, relays, remote radio heads, and so on are placed in a macrocell layout. LTE-Advanced (also known as LTE Release 10) significantly enhances the existing LTE Release 8 and supports much higher peak rates, higher throughput and coverage, and lower latencies, resulting in a better user experience. LTE Release 8, which is mainly deployed in a macro/microcell layout, provides improved system capacity and coverage, high peak data rates, low latency, reduced operating costs, multi-antenna support, flexible bandwidth operation and seamless integration with existing systems.
LTE Release 8 is one of the primary broadband technologies based on OFDM, which is currently being commercialized. In the future, it is possible to obtain more detailed data, and to use complex network algorithms for analyzing this data. Regarding the color of each governorate that degraded from light to dark, which indicated the low to high attraction respectively. In addition, the extracted geographical maps showed each governorate ratio. Thus, based on the total number of flows, the highest attraction rate was between Nineveh and Dhi Qar governorates which reached 64%, while the lowest attraction was between Wasit and Karbala governorates which reached 7%. Furthermore, flows summary among all the governorates as well as for each of them has been obtained separately. These results found that the spatiotemporal interaction models are complementary to the other, as the determined flows based on the radiation model have been used in the gravitational model.
However, the results explore the flows of each governorate at two levels of abstraction: The Macroscopic and Mesoscopic. So, according to the CDRs nature, the well-known spatiotemporal algorithms: the radiation model and the gravity model were applied to analyze these data, and they are turned out to be complementary to each other. The mobile phone data of type Call Detailed Records (CDRs) have been observed, which fall in a 6-month period during COVID-19 in the year 2020-2021. Hence, they are classified based on the human migration at a particular period. The purpose of this analysis is to understand the connection structure and the attractiveness of these governorates through examining the flow migration and population densities. This study aims to analyze the flow migration of individuals between Iraqi governorates using real anonymized data from Korek Telecom company in Iraq. Matin Institut Teknologi Brunei, Brunei Darussalam With today's networks and coverage, it M. It is common to see people communicating via their mobile phones and devices. With the rapid growth of mobile telephony and networks, the vision of a mobile information society (introduced by Nokia) is slowly becoming a reality. As the society moves toward information centricity, the need to have information accessible at anytime and anywhere takes on a new dimension. Early users of wireless technology primarily have been the military, emergency services, and law enforcement organizations. It supports exciting applications such as sensor networks, smart homes, telemedicine, and automated highways.

It has made the network portable because of digital modulation, adaptive modulation, information compression, wireless access and multiplexing. It brings fundamental changes to data networking, telecommunication, and is making integrated networks. INTRODUCTION Wireless networks have been a crucial part of communication in the last few decades and a truly revolutionary paradigm shift, enabling multimedia communications between people and devices from any location (Figure 1).
