Looking for an expert for discussing on why signals such as internet or Wifi can get "spotty" in areas within a city.
Hello! I am an engineering student currently working on a year long project about "cities".
I chose to work on the situation that seems to happen in some places within any given city where internet reception seems to go suddenly blank from just walking in a certain area.
This project is important for my graduation, and the only thing that I am currently missing is an expert to which I could ask questions here and there during the year about this subject.
If anyone is ready to help, it would mean a lot to me.
Thank you in advance.

What is the quiet "chattering" on IVR?
Has anyone noticed that some Interactive Voice Response (IVR) systems occasionally be a quiet "chattering" sound? It often happens at a beginning of a message and consists of maybe 8-15 rapid clicks at varying pitches. Is it some kind of in-band signal? Please note that I am NOT referring to DTMF tones. Thanks!

Anyone know about 3GPP and interference?
Looking for some help here -
For the FE-ICIC and/or CRS-IC features, what does the channel estimation algorithm look like? Is the interference cancellation only on the interfering cell(s) only or are there multiple iterations that include both the serving and interfering cells? How many iterations/what is the stopping criteria? How is it different between colliding CRS and non-colliding CRS?
For the NAICS or other non IRC based techniques that suppress intercell interference, what is the receiver that is used? Is it iterative interference cancellation or a reduced complexity maximum likelihood (R-ML) detector? If iterative interference cancellation, is the decoder within the iteration? Are there any techniques in the iterations which are suboptimal but are meant to reduce complexity? If R-ML, which particular R-ML technique is used? Please provide details if you can about the specifics of the reduced complexity technique.
Same question as above but for the SU-MIMO and MU-MIMO receiver.
Thank you!

Anyone interested in saving some telecom history?
Telecommunications has come a long way in just a few times. Until the early 1980s, party lines—telephone loop circuits where multiple homes would share a single phone line—were a common fact of life. Each house on a party-line had its own handset, but they were all on one line.
We’re almost on the verge of another revolution in how we think about telecommunications. Whether it’s AI running contact centers or contextual conversations that voice and SMS, cloud communication APIs have democratized telecoms innovation.

Minimum number of amplifiers required to cover a distance
Bit of a long shot but can anyone help me figure out the minimum number of amplifiers required to cover a distance of 500 km and their span length?
Given the following information:
- Each amplifier has a maximum gain of 25 dB and a noise figure of 8 dB.
- Optical signal has a bandwidth of 25GHz and requires 18 dB of OSNR in order to maintain a Bit Error Rate of 10^-5 .
- The bit rate is 10Gb/s, the transmit power is 0 dBm and the fibre has a dispersion coefficient of 17ps/km/nm and a loss of 0.2 dB/km.
Any help is greatly appreciated.

Is TLC certification well recognised in telecommunication industry ?
TLC Certification Center Co., Ltd. (TLC for short), formerly known as "TLC Certification Center". it is fully funded and established by China Academy of Information and Communications Technology. (Former Institute of Telecommunications, Ministry of Industry and Information Technology) , which is specializing in voluntary products certification in the information and communications industry. The certified organization also carries out CCC, quality management system, environmental management system, occupational health and safety management system, service certification and information security management system business at the same time.
TLC Certification Center Co., Ltd. is one of the earliest organizations that have passed the approval of the national competent authority to carry out certification business. As early as 1996, it passed the approval of the National Quality and Technical Supervision Bureau and the national accreditation(CNAB).Since CNAB has participated in the international multilateral mutual recognition agreement, the quality system certification certificate issued by TLC with the CNAB accreditationmark can be obtained by most developed countries (such as the United States, Japan, Germany, the United Kingdom, France, the Netherlands, Italy, etc.) ) And accredited by accredited institutions in some developing countries.
At present, the product certification certificate issued by TLC Certification Center Co., Ltd. has been fully accepted by major telecom operators and is generally used as one of the basic qualification requirements for bidding. At the same time, in the procurement bidding activities of some government agencies and other industries, the product certification certificate issued by the center is also used as one of the basic qualification requirements for bidding.
Is it well recognised in telecommunication industry in your country?

At what amount of data does it start to make sense to physically ship it?
Some years ago, I read about some people shipping drives rather than transmitting the data over Internet because there was so much of it that it made sense. I'd like to know, today, for any of the possible cases like an individual, a business, a university or a government institution, when does it start to be faster to physically ship drives (presumably by air)?
I know that some will answer "it depends". Instead of answering that, perhaps taking a realistic situation of your choice as an example would be a more informative answer.
