“…In [14], the ITU recommended antenna profiles are compared with an adapted antenna pattern which exploits elliptic beam lens antenna in order to effectively provide a multi-beam, multi-cell communication network. Also using the ITU recommended antenna profile, Iskandar and Abubaker [15] evaluated an interference mitigation technique for a stratospheric platform (SPF) WiMAX downlink system. In [16], conventional aperture antennas with high directivity are investigated.…”

User-centric joint transmission coordinated multipoint (JT-CoMP) has been shown to enhance the capacity of terrestrial cellular systems, by overcoming cell-edge interference. This paper investigates how JT-CoMP can be extended to a new high altitude platform (HAP) system architecture by exploiting a phased array antenna, which generates multiple beams that form cells, each of which can map on to pooled virtual base-station equipment, thereby replacing multiple terrestrial cell sites. The strategy to implement CoMP is designed to best enhance the user experience at the edge of the HAP cells, including the overall performance of the system. Methods to overcome the known tradeoff for JT-CoMP between carrier-to-interference plus noise ratio (CINR) gain and loss of capacity accessible to the users are considered. Two different methods of identifying non-CoMP and CoMP users are introduced based upon the centralized CINR threshold and flexible CINR threshold approaches. For the bandwidth allocation technique, two approaches are used: full bandwidth (FBW) and half bandwidth (HBW). These four approaches are combined, delivering the FBW, HBW, Flex FBW, and Flex HBW schemes that are used to control the JT-CoMP. It is shown that 57% and 45% of users gain benefit from the use of HBW and FBW, respectively. Overall, the schemes based on the flexible CINR threshold approach provide the best balance between loss and gain of the user capacity, while the centralized CINR threshold-based schemes performed well, beneficiary up to 57% of the users, but with the drawbacks of a higher percentage of losing users.

“…Furthermore, anisotropic antenna type is considered in [47], whereas in [48] an electronically switched beam antenna is deployed that is capable of steering the RF power to and from a certain direction, which can mitigate interference on LAP coverage zones. In [48] [59][60][61][62][63]. However, opinions and decisions vary.…”

“…[62,64] deploy WiMAX technology in their designs for costeffectiveness. In [63] the authors emphasize the advantages of deploying WiMAX over LTE-A in supporting military operations in disaster relief environments where users' requirements change rapidly. On the other hand, WiFi has its own advantages and applications but it suffers from interference, as transmission power levels affect coverage in contrast to a tethered balloon where power can be supplied via a cable [47,59,64].…”

Wireless communications, nowadays, becomes a vital element of people's daily life. Providing global connectivity in future communication systems via the heterogeneous network opens up many research topics to investigate potentialities, enabling technologies, and challenges from the perspective of the integrated wireless systems. This paper aims to drive a comprehensive and comparative study on terrestrial-aerial platforms-satellite wireless communications systems, includes their characteristics and unravelling challenges. The comparison focuses on issues that reportedly can evaluate any wireless systems for temporary events. These issues are altitude and coverage, Radio Frequency (RF) propagation, interference, handover, power supply constraints, deployment and maintenance challenges, reliability on special events or disaster relief, cost-effectiveness and environmental impact. Last, Quality of service (QoS) performance is analysed for the four wireless communication systems from the temporary events perspective using the OPNET Modeller simulation tool. Results infer that space-based wireless systems outperform terrestrial ones.
