Indoor networks became the focus of attention of many researchers due to its important role to connect to the wide networks. Many algorithms have been applied or proposed to maximize the coverage of indoor networks. In this paper, a multi-objective algorithm has been introduced to optimize the coverage and maximize the Signal-to-Interference Ratio (SIR) based on Binary Particle Swarm Optimization (BPSO) using Matlab software. It has been applied to the installed network which is consist of four AP with a heterogeneous distribution. It has been evaluated the optimized network and proves its reliability. The results obtained show the flexibility and efficiency of the proposed algorithm which produce an optimal network maximizes the coverage area and enhances the SIR by 9.03 dB.

In this paper, a scheme for sharing bandwidth-non-orthogonal multiple access (SB-NOMA) based on coordinated multi-point (CoMP) is proposed to improve total sum capacity and user capacity. The proposed algorithm is implemented in a cellular network platform, and the performance is analysed via two cases. First, the network performance is evaluated considerning both channel conditions and interference effects, which is addressed as the worst-case condition. The total network capacity is evaluated assuming Channel Estimation Error (CEE) and Imperfect Successive Interference cancelation (SIC). Second, the network is tested assuming ideal case condition materialized by canceling the effect of inter-channel interference (ICC) of the Base Station (BS) on Near User (NUE). The simulation results show that the capacity increases for SB-NOMA with installed by increasing the number of Cooperative BS (CBSs), where (2bits/Hz/s) is the gain in total capacity that is achieved by increasing the CBSs by one. Moreover, power allocation to the proposed scheme shown (0.15 - 0.85) represents the best value for maintaining capacity achievement.

Communication networks have evolved dramatically in recent years and for a perfect network, there are several factors to focus on to get the perfect coverage and ideal network. Although the network has been installed, the mobile operators’ company keeps reconfiguring the network parameters to achieve the best performance. Even so, some network parameters can’t be modified (tower length, tower position, etc) but other parameters can always be modified due to results of site survey. Also, ICS Telecom was employed to analyze the network performance in terms of coverage and interference due to different values of power and antenna tilt. In this paper, studied the effect of the antenna tilt on the coverage and amount of power from BS to the user in a particular area in Baghdad is studied and it is found that the change in the inclination angle and power have a significant impact on the solutions of the problem of coverage and interference. A comparison field measurement data and simulation data in terms of RSS results in acceptable value equals to 3.24 and 7.45 for 3G and 2G respectively. The performance of the adopted networks is analyses after collecting the data of more than 200 points via two methods: experimentally via drive test and simulation-based on ICS telecom software.
