The implementation of Radio Network (2G/3G/4G) in Indonesia still has many obstacles, especially for the coverage area which is still uneven. So that causes there are still many areas in Indonesia that are classified as bad spot areas, one of which is the Koto Baru Payobasung area, Payakumbuh. This is obtained from the existing simulation carried out, which obtained 2 of the 3 parameters classified in very bad conditions, namely RSRP and Throughput. To overcome this problem, the way that can be used is network optimization. This research implements Carrier Aggregation (CA) using Automatic Cell Planning (ACP) optimization technique with RSRP, SINR, and Throughput parameters. The results showed an increase in each parameter, where the ACP technique obtained an RSRP value of = -103 dBm, SINR of = 2 dB, and Throughput = 15 mbps. As for the CA technique, the RSRP value = -90 dBm, SINR = 7 dB, and Throughput = 50 mbps. These two optimization techniques show that implementing CA is more effective than the ACP technique due to the value of the optimization parameter results.

“…The third generation of wireless communication, known as UMTS, which enabled higher data exchange rates through high-speed downlink packet access (HSDPA) and highspeed uplink packet access (HSUPA) and featured video chatting, did not arrive for ten more years. The commercial deployment of the fourth generation, referred to as longterm evolution (LTE) with Internet Protocol, or IP calling and worldwide interoperability for microwave access (WiMAX) [4], initially came in Oslo and Stockholm [5], but the stronger upgrade, LTE advanced (LTE-A), came in February 2011 with advanced multimedia featuring wireless broadband with a data rate up to 1 Gbps [6], which is ten times faster than regular LTE [7]. However, the fifth generation took only eight years to be introduced, as Chicago and Minneapolis were the first to experience 5G connectivity in April 2019 [8].…”

A design of a self-complementary dual-band fifth-generation (5G) antenna for a wireless body area network (WBAN) has been presented in this paper. Like many other advantages, dual-band antennas have the benefit of being able to establish a reliable wireless connection in places that are frequently out of reach. The antenna operates at two popular 5G NR, FR-2 frequency bands: n257, or 28 GHz, and n260, or 39 GHz. FR-2 bands are prominent for high-speed data transactions within a limited range, which is perfect for WBAN applications. The proposed self-complementary single element design has a physical size of 6 mm × 8 mm × 1.59 mm and is designed with a Rogers RT6002 substrate with a dielectric constant of 2.94. In free space simulations, the antenna performed satisfactorily, achieving around 90% efficiency and having return losses of 16.32 dB and 20.47 dB at the lower and upper frequency bands sequentially. The antenna generated almost omnidirectional patterns at both frequencies with a peak gain of 4.74 dB. By placing the antenna next to a 3D human torso phantom that had been digitally created with accurate human body features, the design’s onbody performance was assessed. Onbody simulations produced favorable performance with a small dispersion from their peak values in some parameters, i.e., efficiency and reflection coefficients but produced more gains: 4.34 dBi at 28 GHz and 6.19 dBi at 39 GHz. For further distance-based investigation, the antenna was placed in five different positions relative to the torso. The test yields 67% efficiency with the minimum gap and 71% at the highest distance from the human body for the lowest band. Though the lower-frequency band produces better results with more gaps, the higher-frequency band performs consistently better in even the closest placement to the human body model by reaching more than 6 dB of gain with above 81% efficiency and wider than 10 GHz of bandwidth. The overall performance indicates this design can be a good solution to complex WBAN scenarios.
