Utilizing ultra-wideband with wireless telecommunications applications microstrip

<p>The small aspect, as well as low margins of the microstrip chip amplifier (MPA) is being used in a contact system. For the last few times within the last year's research, the majority of work with MPA has been centered towards designing the portable antenna design. Wireless networking systems may be fitted with a new ultrawideband digital monopoly antenna. Throughout this exponentially changing environment, and dual multi-standard antennas play a crucial role in the implementation of cell towers. This paper presents the nature of an ultra-wideband (UWB)-based antenna array for the shape of a substratum, feeding strategies or openings.</p>

Low Loss LTCC Ag System for 5G Applications

Low dielectric constant/low loss LTCC materials have drawn much attention with the emergence of 5G wireless telecommunications. LTCC offers unique properties in the millimeter wave frequency range. The low dielectric constant and dielectric loss enable low latency devices with enhanced performance. To meet the market demands of higher performance and lower cost, Ferro has developed a new M7 LTCC/Ag cofireable system suitable for antenna in 5G and other high frequency applications. M7 LTCC ceramic green tape and cofireable Ag conductors have been developed and tested. Properties of the LTCC/Ag system are included herein including high frequency dielectric properties.

Electric Field Sensing with a Modified SRR for Wireless Telecommunications Dosimetry

Split ring resonators (SRRs) have been used extensively in metamaterials, showing a strong localization and enhancement of fields, which significantly improves the sensitivity and resolution of the electromagnetic field sensors. We propose the development of an electric field sensor for 2.4 GHz industrial, scientific, and medical (ISM) band applications, by modifying the renowned SRR to contain three concentric pairs of rings. The reduced size makes the sensor affordable for experiments by inserting it in phantoms in order to measure the specific absorption rate (SAR). Power was transmitted from a patch antenna to SRR, with a varying set of distances 1λ, 2λ, 3λ, or 5λ. Experimental measurements of power were conducted with and without a cylindrical distilled-water phantom with agar (4.54%) and NaCl (0.95%). We then computed the electric and magnetic fields and the SAR using these experimental readings of power for different distances. Our sensor was able to measure power values from 20 nW to 0.3 µW with no phantom, and 1 nW to 10 nW with a phantom, in accordance with the values reported for radiofrequency (RF) dosimetry. The sensitivity as a function of the distance determined for the specific case of a phantom was 0.3 µW/cm.

Modeling of an ultra-wideband GHz range antenna with recursive topology

For decades the development of telecommunications devices shows an inspiring progress. Nowadays, a wide range of multifunctional wireless telecommunications devices with small weight and size characteristics is being developed, since these are portable devices. One of the most important elements of such a device is the antenna. The antenna has a number of conflicting requirements: a wide frequency band, compact size, simple manufacturing technology, low price, the ability to work in several frequency bands, etc. One of the promising types of ultra-wideband antennas with a high gain is fractal antennas with a recursive topological pattern.

COVID-19 Attributed Cases and Deaths are Statistically Higher in States and Counties with 5th Generation Millimeter Wave Wireless Telecommunications in the United States.

COVID-19-attributed case and death rates for the U.S.A. were analyzed through May 2020 in three ways – for all 50 states, the country’s largest counties, and the largest counties in California – and found to be statistically significantly higher for states and counties with compared to those without 5G millimeter wave (mmW) technology. 5G mmW index was a statistically significant factor for the higher case and rates in all three analyses, while population density, air quality and latitude were significant for only one or two of the analyses. For state averages, cases per million were 79% higher (p = 0.012), deaths per million were 94% higher (p = 0.049), cases per test were 68% higher (p = 0.003) and deaths per test were 81% higher (p = 0.025) for states with vs. without mmW. For county averages, cases per million were 87% higher (p = 0.005) and deaths per million were 165% higher (p = 0.012) for counties with vs. without mmW. While higher population density contributed to the higher mean case and death rates in the mmW states and counties, exposure to mmW had about the same impact as higher density of mmW states on mean case and death rates and about three times as much impact as higher density for mmW counties on mean case and death rates. Based on multiple linear regression, if there was no mmW exposure, case and death rates would be 18-30% lower for 5G mmW states and 39-57% lower for 5G mmW counties. This assessment clearly shows exposure to 5G mmW technology is statistically significantly associated with higher COVID-19 case and death rates in the U.S.A. The mechanism–should this be a causal relationship–may relate to changes in blood chemistry, oxidative stress, an impaired immune response, an altered cardiovascular and/or neurological response.

From Fan-Centric Handset Manufacturing to Intense Product Diversification

Xiaomi Corporation is a very successful company in the wireless telecommunications industry in China. The company has been able to adopt a “fan-centric” business model that includes extensive input from their customer base on handset design, user interface design, and features for other products/services offered by the company. The “innovation ecosystem” the company created has allowed a recent surge in sales and popularity that provides a model for other wireless telecommunications companies ranging from network service providers to application developers to follow.

A Survey of Using Swarm Intelligence Algorithms in IoT

With the continuing advancements in technologies (such as machine to machine, wireless telecommunications, artificial intelligence, and big data analysis), the Internet of Things (IoT) aims to connect everything for information sharing and intelligent decision-making. Swarm intelligence (SI) provides the possibility of SI behavior through collaboration in individuals that have limited or no intelligence. Its potential parallelism and distribution characteristics can be used to realize global optimization and solve nonlinear complex problems. This paper reviews representative SI algorithms and summarizes their applications in the IoT. The main focus consists in the analysis of SI-enabled applications to wireless sensor network (WSN) and discussion of related research problems in the WSN. Also, we concluded SI-based applications in other IoT fields, such as SI in UAV-aided wireless network. Finally, possible research prospects and future trends are drawn.
