How long does it take to a journal indexed in the "Emerging Sources Citation Index" get an Impact Factor? What is the future of journals indexed in Emerging Sources Citation Index?

Hi frds,

quite stunning what people do, when they have access to simple chat functions on a smart phone? Doxxing seems to be the gold standard, especially during a pandemic. Seems free speech may have adverse consequences.

Therefore, given the exponential possibilities of telecommunication devices, do we need some sort of ethical passport before being allowed to use telecommunication devices?

Cherish your feedback.

In all the papers and books that I read, only the DC channel gain of the VLC system is studied without any further justification. How can we know for sure that the channel doesn't affect the frequency of the light? What would the spectrum of the channel look like with an LED modulated in OOK?

Hello to all

Two questions

1. Does the use of metals with high magnetic permeability, such as iron alloy in the waveguide, cause insertion losses?

2- What about chrome or copper plating?

If you know the article in this field, please introduce it. Thank you

2-How to test it with Network Analyzer after making it?

I want to parse signals coming from 4G/5G towers to extract only the ID of the tower and the transmission time (on simplex communication: only downlink). Are these packets (or frames) sent on a regular time interval ?

Assalaamu alaikum

As a faculty member of Engineering in a university, I wish to have clear idea as to how should we adapt ourselves with respect to following scenarios on the verge of 4th industrial revolution:

1. How should the subjects taught change in the domain of Electrical, Electronic, Telecommunication and Computer domain in engineering?

2. What role should industries play in developing contents of local universities?

3. How should the teaching learning methodologies evolve?

4. Should the assessment procedure remain same? Or should we move on from formative exam based assessments to project based ones?

5. How much role should industries play in the teaching learning activities of universities e.g. industrial trainings, taking interns, arranging seminars and workshops, short training courses etc.

6. How should industries use the universities in solving their novel problems through sponsoring researches in universities.

Please note that, i come from a country where university-industry collaboration is still a relatively new term. Looking for expert opinions from colleagues around the world.

Please feel free to answer any of the topics or add your own discussion outside the topics but relevant to the subject matter. Hoping to see some engaging discussion that will enlighten us all.

All,

I need your suggestions/ideas on M.Tech dissertation topics in DataScience in NMS/EMS preferably in Telecommunication domain. Thanks in advance.

In the area of electronic banking, including mobile banking, commercial banks improve technological solutions for the use of smartphones for the purpose of conducting financial transactions by clients.

Commercial banks spend the most resources on developing security systems, reducing gaps in online banking systems used by cybercriminals and improving IT systems risk management procedures.

The changes taking place in online banking, including mobile banking, are currently determined primarily by the technological progress related to telecommunications and IT devices.

In view of the above, the current question is: Determinants of the development of mobile banking?

Please, answer, comments.

I invite you to the discussion.

Kindly suggest which routing algorithm is better to implement for finding the optimal route in wireless adhoc networks? 

Performance criteria :end to end delay , packet delivery ratio, throughput

My experience is that if teleconferencing must be used, it is best to have 100% of the participants access the teleconference individually. If all participants access the teleconference individually, regardless of whether the video feature is used, engagement is higher. If some of the participants are clustered in groups, there is almost always "side bar" or private conversations that detract from the overall effectiveness of the meeting. A single participant, or small group of participants clustered together, simply cannot compete with a larger group, especially if the meeting leader/facilitator is located with the large group! Does any research substantiate my experience?

I need help with Queuing theory, easy explanation to M/M/C?

What are the parameters of the M/M/C queuing model?

Russian project to explore the moons of Jupiter after 2030 will be based on the nuclear propulsion spacecraft "Nuklon" with an electrical energy power of 0.5 MW. Such energy power gives the opportunity to significantly increase a data transfer performance to Earth. In my opinion, the speed of data transfer can be increase to 100 Mbit/sec. This value will be enough to use 4K Video for the investigation of dynamic processes in the atmosphere of Jupiter and moons. What is your opinion about this?

Following an influential analysis published in February, a team of Stanford University researchers has conducted the first large survey into the very modern phenomenon of "Zoom Fatigue."Over the last year, millions of people have been working from home. Meetings previously conducted in person suddenly shifted to video conferencing platforms such as Zoom. And as 2020 progressed, more and more people started noticing a unique kind of exhaustion at the end of a day filled with video meetings. Referred to as "Zoom Fatigue," this new phenomenon is now the subject of novel academic research. https://newatlas.com/telecommunications/stanford-zoom-fatigue-first-study-women-more-affected/

So, what do you know about "zoom fatigue" ...Who are the groups most vulnerable to it ??? And why ??? Can its effects be minimized ???

All comments and contributions are welcome.

Hello everyone.

I install the receving antenna for my receiver on the same tower that have broadcast-FM antenna . The broadcast-FM transmitter operate around 15 kiloWatts and the distance between those antenna are not so far (<<< 5 metre vertically).

Now I feel that my receiver can't pickup low signal and sometime when the broadcast-FM transmitter went under the routine maintainance, Everything is back as it was.

What problem am I facing ?

and If I want to solve this problem what should I do ?

Thank you

Here, i am suggesting the use of market basket analysis as follows:

1) Getting user features (e.g. usage, demographic, etc.)

2) Segmenting customers into groups based on their features.

3) Identifying purchasing/spending behavior regarding previous offers.

4) Use association rule mining (or market basket analysis) to extract rules.

5) Use these rules to give predictions about the next best offer for each user.

Any suggestions/improvements/notes are welcome. Thank you.

Hello All,

I am presently enrolled as an MSc Electrical Engineering (Telecommunication Option). I have finished my coursework and about to engage in my research but I am having difficult in getting a Research Proposal Topic. I actually want to work in Satellite Communication but also finding it difficult to narrow the area of interest. With this, I am kindly asking for your assistance/guidance or any suggestion that might help. Thank you for considering my request and look forward to hearing from you.

Kind regards,

Sajor Barrie.

Presently, there are 7 layers of OSI(Open Systems Interconnection) model in telecommunication:-

1. Physical layer

2. Data link layer

3. Network layer

4. Transport layer

5. Session layer

6. Presentation layer

7. Application layer

So, the root question is can the no. of elements in the 7 layers of OSI model be decreased to fewer elements? And if yes. Then what are the elements can be eliminated in the communication networking?

hello everyone,

according to your experiences in paper's submission, can you propose to me a scientific journal related to the field of networks and communications with an acceptable impact factor, and a shorter reviewing duration.

thank you

We know that the equation of refractivity has 3 parameters (Ambient temperature, relative humidity, and atmospheric vapour pressure which relates to atmospheric pressure) as recommended by the International Telecommunication Union (ITU). My question seeks to find out if an alternative equation can be modeled and how???

What is the maximum speed of user at which GSM link can perform?

When Carrier Aggregation and cross-carrier scheduling are applied in LTE-Advanced system, UE may support multiple Component Carriers (CC) and control information on one CC can allocate radio resource on another CC. Search space of all CCs and control information is only transmitted from a chosen CC. In this case, if search spaces of different CCs are not properly defined, high blocking probability of control information will be very harmful to system performance.

My Question is: What is the cause of this blocking, is it deficiency of control channel elements to served, scheduled UE or what?

My guess is not but I have no proof of this. Can any expert help?

For now, I assume either self-overlapping or high mutual over-lapping of the UEs' search spaces as the likely cause of blocking.

Assuming that a cellular operator is currently using FDD LTE spectrum, how difficult (in terms of the cost and the required changes to the system) is to switch to TDD? Is it technically possible to use the same spectrum but for TDD? If not, why is that so? Is there any legacy issue? And last but not least, how difficult is for an operator to add TDD 5G to its FDD LTE network?

I would appreciate your opinion.

Different companding methods such as μ-law, hyperbolic tangent, exponential, linear symmetric transforms, linear asymmetric transforms and threshold log companding are used for PAPR reduction in OFDM.

Is there any other efficient companding methods?

Besides, is there any other method of PAPR reduction in OFDM except companding?

I have a Bsc Physics and Solar Energy degree and I'm presently considering a master degree in telecommunication. I want to combine wireless communication with solar energy.

What do you notice changes in behavior, sociological changes in societies in connection with the advancement of telecommunications technologies?

More and more information is contained in our smartphones? More and more practical information, contacts etc. are archived in smartphones without remembering them.

Once, in the era of fixed-line telephony, people knew by heart the telephone number, whereas now in the era of mobile telephony, mobile, when all information is stored on a smartphone, people remember less and less.

In connection with the above, it is an example of the progressive changes in behavior, sociological changes in societies in connection with the progress of information and telecommunications technologies.

Do you notice these changes?

What are you noticing other progressive changes in behavior, sociological changes in societies in connection with the progress of information and telecommunications technologies?

In telecommunications, a transmission system is a system which transmits a signal from one place to another. The signal can be an electrical, optical or radio signal.

Can we consider some of the human body systems as transmission systems and then model it using telecommunications' concepts for better understanding?

If we do, can someone please provides some examples of these systems and determines their basic elements(message, transmitter, medium and receiver)?

Without using triangulation, how might one broadcast a signal that would only be picked up by one antenna out of the many present?  Or, if not one antenna, then perhaps just a few close by.  These antenna are not stationary.  We can use any frequency that we want, although a higher frequency would be best.  Each antenna has a slightly different Q, length, and width.

Forward Error Correction (FEC) schemes square measure a necessary a part of wireless communication systems. The number of symbols inside the availability encoded message is enlarged in an passing controlled manner thus on facilitate a pair of basic demands at the receiver one is Error detection and alternative is Error correction. In telecommunication and data theory, forward error correction (FEC) (also referred to as channel coding]) may be a system of error management for knowledge transmission, whereby the sender adds consistently generated redundant knowledge to its messages, additionally referred to as associate error-correcting code (ECC). In digital electronic systems, data is painted in binary format (1's and 0's).When binary data is passed from one purpose to a different, there's continually some likelihood that a slip-up are often made; a one understood as a zero or a 0 taken to be a 1. This can be caused by media defects, electronic noise, component failures, poor connections, deterioration due to age, and other factors. When a bit is mistakenly interpreted, a bit error has occurred. Error correction is the process of detecting bit errors and correcting them and can be done in software or hardware. For high data rates, error correction must be done in special-purpose hardware because software is too slow. A group of bits in a computer has conventionally been referred to as a "word.” Each bit can be thought of as one of two "letters,” 0 or 1. Error correcting systems add extra or "redundant" letters to computer words. The extra letters (bits) add a certain structure to each word. If that structure is altered by errors, the changes can be detected and corrected.

Fintech, is a term that is used a lot but not necessarily understood by everyone because it encompasses a breadth of players, products and issues as well as straddling the financial and several other sectors including telecommunications, retail, data analytics and device manufacturing. What unites these sectors is the “tech” in Fintech. Technology has always been a driver of growth and innovation in business but none more so than in the financial services sector. Understanding a combination of economics, finance, technology, government policy, regulation, strategy and importantly social and customer trends helps us to understand how innovation is accelerating change.

Smart Computational devices and Ubiquitous Connectivity require high bandwidth, which drives Telecommunications Industry to innovate.

I want to explain briefly the EMR that comes from Telecommunication towers

How does a CoMP scheduler work? Also what are the differences with conventional schedulers and its advantages?

The nanosatellite operating in amateur radio frequencies have limited bandwidth. 2m band have 144-146MHz and 70cm band have 434-438MHz. How much bandwidth (Maximum) we can use in this?

Norwegian Post and Telecommunication Authority (NPT) says the maximum bandwidth are limited to 18KHz and 30KHz respectively. Is this applicable for every region?

On 8th page of document Johan L. Tresvig say a regulationby norwegian goverment. What I would like to know is whether any other contries or organization set a limit to the bandwidth.I couldn't find much details about this in internet.

Dear Colleges,

Information and Communications Technology (ICT) is an extended term for information technology (IT) which stresses the role of unified communications[1] and the integration of telecommunications (telephone lines and wireless signals), computers as well as necessary enterprise software, middle-ware, storage, and audio-visual systems, which enable users to access, store, transmit, and manipulate information.[2]. However can we measure against Project Management by the volume,velocity variety and value to see the critical path of Project.
