The deployments combining enhanced Wi-Fi standards, Beyond 5G (B5G), and upcoming 6G based Radio Access Technologies (RAT), all of which are thought to be a part of the Future or 6G-based Wireless & Mobile Heterogeneous Networks, are highlighted in this article with particular emphasis (6G-WMHN). So, mobile broadband subscriptions grow twice as fast as the fixed ones and the Internet of Things (IoT) comes forth, the Byeond 5G (B5G) and 6G vision of the Internet of Everything (IoE) (people, devices, and things), becomes a substantial and credible part of the near future. The goal of this paper is to shed light on B5G/6G network planning. In this paper, firstly, we give a brief overview of the key enabling technologies for B5G/6G network planning requirements including capacity estimation and reservation, and dynamic capacity allocation. In addition, the B5G/6G air interface, and its various propagation models which is suitable for low, mid, and high bands (mmW) spectrum. RF key parameters and planning parameters, traffic types, propagation modeling, and calculation methodology of system throughput and capacity. This paper is illustrating the estimation process for various operational scenario-based B5G/6G link budgets and smart cities and their traffic forecasting. Finally, we propose a planning tool that takes into consideration many practical aspects such as flexibility, high reliability to smart cities, and multi-operating frequency bands. The Model supports High-loss and Low-loss models, Massive MIMO with beamforming. The presented results cover different types of smart city configurations such as street canyons, business areas, downtown, and shopping areas. The planning crossing point (from coverage oriented to capacity-oriented and vice versa) is deducted iteratively by the presented model.","PeriodicalId":156721,"journal":{"name":"2022 39th National Radio Science Conference (NRSC)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116444533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The geometry of the radiating monopole patch is described by only one length parameter and two angular parameters. For more enhancement of the bandwidth and radiation efficiency, the radiating patch is fed through a coplanar waveguide (CPW) to produce the antenna structure printed on one side of a high-quality thin dielectric substrate which effectively reduces the losses within the operational frequency band.

Device-to-Multi-Device (D2MD) is one of the cutting-edge technologies that has great promise for fifth-generation (5G) and beyond Fifth-generation (B5G)/Sixth Generation 6G, and it will significantly improve network performance as a whole. Due to the network’s heterogeneity, we must assign a significant amount of spectrum resources, so we must come up with workable alternatives. Clustering techniques aid in resource management, particularly when network resources are scarce. In this paper, we investigate the cluster formation problem and user collations assignment by using the One-to-Many resource allocation scheme. Cluster formation is formulated as cluster head (CH) and cluster requesters’ nodes (CRns). The optimization problem is done by proposing a matching theory with two-sided using Gale shapely algorithm and user collations assignment after selecting the appropriate (CH). Each cluster is ruled by only one (CH) and multiple (CRns) but is limited to guaranteeing the Quality of service (QoS) and mitigation of interference.","PeriodicalId":156721,"journal":{"name":"2022 39th National Radio Science Conference (NRSC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123383646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed procedure depends on the signature formed by the internal resonances of the cavity-backed apertures existing as the air-inlet and exhaust-outlet pipes of the jet engine. These pipes are modeled as open ended conducting cylindrical tubes of practical dimensions with radial conducting blades placed inside the cylindrical cavity. A compressed radar pulse is formed by chirping using linear frequency modulation (LFM) to cover the frequency band 1.0 – 2.0 GHz that is wide enough to distinguish between various targets. The radar cross section (RCS) as a function of the frequency is obtained through electromagnetic simulation using the CST® simulator and employing the pipe model and the pulsed plane wave mentioned above. The proposed target identification algorithm is mathematically described and numerically applied to identify different targets. The numerical examinations show that the proposed algorithm succeeds to take the correct decision regarding the target identification by active and hybrid homing missiles.","PeriodicalId":156721,"journal":{"name":"2022 39th National Radio Science Conference (NRSC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128367717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The antenna elements in the MIMO configurations have been isolated from each other using two different techniques. The first technique is using polarization diversity for the elements (using the orthogonal polarization technique), whereas the second technique is using a cross-defected ground for the four antenna elements. The single antenna element is a microstrip patch antenna, positioned and fed according to the polarization diversity. Thanks to the proposed design techniques, the proposed MIMO antenna has a good MIMO performance at the bandwidth centered at 5.8 GHz. An optimization process is performed by adding a DGS filter structure to the system, The use of the DSG reduced the mutual coupling from 20 to 41 dB between co-polar elements. MIMO system performance is evaluated through deriving MIMO parameters such as envelope correlation coefficient (ECC) and diversity gain (DG). Also, a channel capacity loss (CCL) is calculated for both MIMO configurations. Detailed figures for all derived parameters are illustrated.
