“…As the selection of operating frequency for proposed PA is also an important consideration, various frequency bands such as LTE & 5G new radio (NR) [24]- [26] are analysed for appropriate selection of proposed PA's operating frequency and BW. Based on the analysis, a new sub-6 GHz frequency band with a centre frequency of 3.5GHz, called Citizen Broadband Radio Service (CBRS) [27] will be the appropriate choice for 5G wireless communications of AMI in a smart grid. Therefore, the proposed PA initially designed to operate at 3.5GHz centre frequency.…”

The wireless communication networks for Advanced Metering Infrastructure (AMI) / smart metering applications of a smart grid are in need of emerging 5G technology for providing a significant enhancement in bandwidth (BW) to support a large amount of data transmission between the Meter data management system (MDMS) of operation centre and smart meters efficiently. The entire wireless communication network’s BW and efficiency mainly depend on its Power Amplifier (PA). The design of PA that can provide high efficiency with linearity over a wide BW is essential to meet the 5G wireless communication network requirements of AMI / smart metering applications. This paper presents the design methodology of a two-stage PA that operates at a 3.5 GHz centre frequency by utilizing the CGH40010F model GaN transistor. This PA employs a Class-J mode for the power stage that will be driven by a Class-AB mode to achieve high efficiency with improved power gain over desired BW. The matching Networks(M.Ns) of the proposed two-stage PA are designed with the idea to replace its passive lumped inductors with active inductors, based on the desired optimum impedance values obtained from the load-pull techniques utilizing the ADS EDA tool. The proposed two-stage PA delivers a power output of 41dBm with 21 dB of power gain over a BW around 400 MHz, a maximum Power Added Efficiency (PAE ) of 53% and maximum drain efficiency (D.E) of 54% with a small signal gain of 27dB at 3.5GHz using 28V power supply into 50 Ω load.

Smart grid operators seeking to extend their wireless network capacity can use unlicensed bands. However, devices in these shared bands must follow rules such as Listen Before Talk (LBT), standardized by ETSI. In this paper, we focus on the performance of the frame-based equipment (FBE) version of LBT channel access. We design, implement, and validate a fully functional FBE channel access simulator. Next, we conduct an extensive performance analysis of the FBE variants encountered in the literature, focusing on channel efficiency and fairness in upper-bound and coexistence scenarios. Our study leads to several conclusions about the operation of FBE-based devices, including the need for proper configuration of channel access parameters to ensure fairness and optimal performance. We also observe generally poor coexistence among FBE variants: the highest Jain’s fairness index was only 0.88, with an average normalized channel efficiency of 0.76. Therefore, we identify several open research areas in the field, such as the need for further development of parameter adaptation algorithms, the deployment of an external controller to update channel access parameters, and new FBE designs with better coexistence qualities.

“…HetNet is a cognitive network in such a way that all available radio spectrum or channel that coexist within a region will be fully utilized for both primary and secondary users [10][11][12], including television signal white space [13][14][15]. Such spectrum sharing or borrowing can happen among licensed and unlicensed networks [16][17][18][19]. In 5G, millimetre wave (mmWave) is newly introduced as well as part of the architecture.…”

Interference minimization in cellular network has and will always be top priority, whether in current or future generation of cellular technology. Therefore, cellular channel assignment problem (CAP) requires continuous study and research. This paper presents the study and comparison of Genetic Algorithm (GA) and Particle Swam Optimization (PSO) for CAP in minimizing interference. GA with three variants in term of population selectionroulette wheel selection (RWS), tournament selection (TS) and stochastic universal sampling (SUS) were studied, and then compared with classic PSO. Two CAPs were derived and used to comprehensively evaluate the performances of the PSO and GAs. It was found that GA-TS is ~11% and ~7% faster than GA-RWS and GA-SUS, respectively. Although the difference is small, but it allowed GA-TS to run for few more iterations and eventually achieved better interference minimization. Moreover, it was also found that GA-SUS has less noise and produce a more consistent result. On the other hand, PSO is slower than GA-TS, but has higher potential to converge on smaller minimum value.
