“…In order to accommodate user traffic demand during the ultra-dense deployment phase in the mmWave band, the authors of [30] advocated increasing sectorization and the number of antennas. Tseng et al [31,32] investigated the installation of an ultra-dense network with various BSs running at frequencies ranging from GHz to GHz. However, the positioning of BSs during the cell planning process in a real-world scenario, as well as the customers' data rate requirements and cell coverage restrictions, were not considered.…”

“…Many new 5G-capable items operating in sub-GHz and mmWave bands are entering the market as the 5G rollout advances and researchers continue to propose 6G. Small stations/repeaters and handheld devices with 5G front ends use phased arrays as high-gain antenna systems to deliver great data throughput without reducing range at higher frequencies [31]. The ITU-R report's definition of base station antenna parameters for 30 GHz operating frequency is used in this paper [48].…”

Information and communications technologies play a vital role in achieving the Sustainable Development Goals (SDGs) and bridging the gap between developed and developing countries. However, various socioeconomic factors adversely impact the deployment of digital infrastructure, such as 5G networks, in the countries of Oceania. The high-speed broadband fifth-generation cellular network (5G) will improve the quality of service for growing mobile users and the massive Internet of Things (IoT). It will also provide ultra-low-latency services required by smart city applications. This study investigates the planning process for a 5G radio access network incorporating sub-6 GHz macro-remote radio units (MRRUs) and mmWave micro-remote radio units (mRRUs). We carefully define an optimization problem for 5G network planning, considering the characteristics of urban macro-cells (UMa) and urban micro-cells (UMi) with appropriate channel models and link budgets. We determine the minimum number of MRRUs and mRRUs that can be installed in each area while meeting coverage and user traffic requirements. This will ensure adequate broadband low-latency network coverage with micro-cells instead of macro-cells. This study evaluates the technical feasibility analysis of combining terrestrial and airborne networks to provide 5G coverage in Oceania, with a special emphasis on Fiji.

“…PT ĨRS is the signal power of an interference from an IRS. The PL i, j ,k refers to the free space loss recommended by ITU-R in [36], which is calculated by PL i, j ,k = 20 log 10 (d i, j ,k ) + 20 log 10 ( f ) + 32.44, (7) where d i, j ,k is the distance in kilometers between two of three, that is, CPs z i and z j , and the TP q k , and f is the carrier frequency in MHz. Let L be the set of all vertices on a signal transmission path, and G L = (L, E L ) be the vertex-induced graph of the path in G , which is a tree structure used to connect a BS and an IRS or multiple IRSs.…”

“…To overcome such a problem, a naïve solution would be to deploy as many as possible base stations (BSs) but also increases deployment cost. Hence, it is necessary for communication service providers to increase the coverage region of 6G wireless signals through low-cost and low power consumption signal repeater, for example, small cells in heterogeneous cellular network [6,7].…”

Intelligent reflecting surface (IRS) composed of a large number of low-cost, phaseadjustable passive reflecting elements, which is an attractive solution of overcoming the signal attenuation and interference. IRS can be used as a low-power passive system with signal enhancement and interference suppression. However, the planning problem of a large-scale network contains a great numbers of base stations (BSs) and IRSs is challenging. The network planning problem considers limited deployment cost and signal enhancement at the same time is vital. Here, the 6G wireless signal coverage (WSC) problem with the consideration of both BS and IRS is considered. More specifically, the 6G WSC problem is first formulated through the integer linear programming. Due to its obvious NP-hardness, two efficient heuristic algorithms that can reach a near-optimal solution, that is, the WSC algorithm and the tree-based WSC (TBWSC) algorithm is then proposed. Simulation-based results showed that the proposed WSC algorithm achieves lower total cost than that of the TBWSC algorithm but also results in lower signal quality. The proposed TBWSC algorithm obtains the planning result with the highest signal quality and slightly higher total cost. Both proposed algorithms can find better planning results of multiple BSs and IRSs for 6G wireless communications.
