Following questions were raised by anonymous website visitors or readers to the online publishers. We'll check up a few queries among them below.


Reason behind change in network upgradation from 1g to 5g?

In a nutshell, the answer to this issue is that bandwidth demands are increasing. The bandwidth allotted to a specific service, for example, is fixed. Now, if the number of devices linked to the internet is growing by the day, what would you do to meet the increasing bandwidth demand? As a result, every few decades, a whole new G (or generation in cellular wireless communication) appears to meet the required requirements. Read More ...


Does my PDA support 5g?

It is entirely dependent on the mobile or cell phone's operational frequency band. More specifically, the frequency band that your mobile antenna receives or broadcasts is determined by your antenna.


Can a CSE can study 5g courses?

Prerequisites to pursuing a 5G course:

You must have some good understanding in previous G's especially in Telecommunication to pursue a 5G course. Here concept of cell, operating frequency, infrastructure all are different as compare to 3G or 4G network. The key technologies to enable 5G are

You must have basic knowledge about wireless channel model, modulation schemes used in 3G and 4G, antennas used in those technologies, etc. to make yourself fit for pursuing a course on 5GMIMO Technology, SVD, etc.Basic knowledge on UWB or millimeter wave is a big plus for that.


What additional benefits may you expect if you have a background in computer science or engineering?

Machine learning (ML) and artificial intelligence (AI) are becoming increasingly important as we advance in technology. Python is a great programming language for machine learning and artificial intelligence. It is a significant benefit if you have a thorough understanding of programming languages, particularly Python. Deep Learning (DL) is a common tool in 5G simulation, bandwidth allocation, beamforming, and channel estimation, among other applications.

It is now entirely up to you whether or if you are interested in 5G courses. We recommend that you have a fundamental understanding of telecommunications, including prior G's such as 3G and 4G, operating frequencies, used modulation or multiplexing techniques, MIMO technologies, and so on.


Any side effects of 5g cables overhead my house

No


Any side effects of 5g cell tower around my house

In reality, cell towers emit radiation at a level that is safe for humans . Only when you receive a call or your signal level on the screen drops below, the cell tower provide more power to your phone. However, that power is also below the standard of safety. According to experts, this is unlikely to cause harm. You may be aware that the transmitted power from cell towers or access points (APs) in 5G communication will be lower than in 3G or 4G.


What are the clusters and side lobes?

A. We usually discuss the term 'time cluster' or 'cluster' in case of extremely high frequency communication system. Where signal gets reflected and refracted multiple times in environment due to very high frequency. When signal (MPCs) come to receiver and they are close in time then they form cluster. Technically, they are (MPCs) close in time in spatial domain.

While reading any chapter on beamforming, you may come across the terms 'main lobe' and' side lobe.' In this case, side lobes are a group of MPCs that are close in angle in terms of AOA (angle of arrival) or AOD (angle of departure) (angle of departure). Continue Reading ...


Which modulation techniques are used in 5G?

A. OFDM, NOMA


What is millimeter wave technology?

A. Millimeter wave band with huge potentiality like -- huge bandwidth resource and ultra low latency properties which is a most suitable candidate to enable millimeter wave 5G communication. Although, most countries are still using sub 6 GHz band for 5G networks. Due to extremely high frequency it's wavelength spans between 10 millimeter to 1 millimeter, so it is termed as 'Millimeter Wave'.


What companies develop 5g antennas?

A. Laird is one of them.


What is the difference between 1g and 5g in switching technique in DCC?


Internet of Things (IOTs)


How is career in IOT?

A. IoT professionals have a bright future. Almost every person will use IoTs, sensors, and wearables for their daily requirements in the near future. It can be used in a variety of businesses, from home appliances to heavy industries. Hospitals, fleet management, traffic control, smart cities, and other applications can all benefit from it.

Calculation of SNR from FFT bins in MATLAB

๐Ÿ“˜ Overview ๐Ÿงฎ MATLAB Code for Estimation of SNR from FFT bins of a Noisy Signal ๐Ÿงฎ MATLAB Code for Estimation of Signal-to-Noise Ratio from Power Spectral Density Using FFT and Kaiser Window Periodogram from real signal data ๐Ÿ“š Further Reading   Here, you can find the SNR of a received signal from periodogram / FFT bins using the Kaiser operator. The beta (ฮฒ) parameter characterizes the Kaiser window, which controls the trade-off between the main lobe width and the side lobe level in the frequency domain. For that you should know the sampling rate of the signal.  The Kaiser window is a type of window function commonly used in signal processing, particularly for designing finite impulse response (FIR) filters and performing spectral analysis. It is a general-purpose window that allows for control over the trade-off between the main lobe width (frequency resolution) and side lobe levels (suppression of spectral leakage). The Kaiser window is defined...
