“…It was shown that electrical tilt is optimal for cell edge performance and mean throughput. However, for achieving peak throughput, a loss of 25% is observed using electrical tilt only and a loss of 7% for mechanical tilt only, as compared to using a combination of both [49]. Despite the simulation results provided by the authors listed above, it is our opinion that implementing electrical tilt remotely requires less effort and is better suited for self organising networks.…”

This article surveys the literature over the period of the last decade on the emerging field of self organisation as applied to wireless cellular communication networks. Self organisation has been extensively studied and applied in adhoc networks, wireless sensor networks and autonomic computer networks; however in the context of wireless cellular networks, this is the first attempt to put in perspective the various efforts in form of a tutorial/survey. We provide a comprehensive survey of the existing literature, projects and standards in self organising cellular networks. Additionally, we also aim to present a clear understanding of this active research area, identifying a clear taxonomy and guidelines for design of self organising mechanisms. We compare strength and weakness of existing solutions and highlight the key research areas for further development. This paper serves as a guide and a starting point for anyone willing to delve into research on self organisation in wireless cellular communication networks.

“…In systems with small cell size (where the distance between the cell centre and the cell edge is very less), electrical tilting proves to be a cost effective and trivial solution to the interference problems. While mechanical tilt provides reduced coverage in the central direction and more coverage in side directions, pattern blooming [7], the vertical tilt results in uniform modification in the antenna radiation pattern (i.e. antenna gain on the horizon decreases).…”

“…Antenna orientations are known to have a major influence on the performance of a wireless communications link. An analysis of the impact of antenna tilt on LTE coverage and capacity was analyzed in [6] where system performance was affected by different combinations of electrical and mechanical tilt. The downlink performance of an 802.11n system with antenna pattern orientation was also addressed in [7].…”

The initial deployments of antenna in the handset consist of fixed non-rotated antenna for transmitting and receiving the signal in the wireless communication scenario. However, link correlation at the UE shows very bad performance when the handset rotates in landscape position. This paper evaluates the impact of accelerometer on the downlink propagation channel of 3G smartphone for non-line-ofsight links. The performance average received signal power is studied for user equipment. Results show that the exploitation of an accelerometer provide better performance in terms of received signal power when the handset rotated from portrait to landscape position. It can be concluded that the deployment of accelerometer can be used to improve existing 3G smartphone received signal. Results also indicate that accelerometer can be used to improve downlink throughput since the signal-to-noise-power is increased by approximately 16%.
