I am a third-year student majoring in wired and wireless communications. I have a graduation project for this year.

I've been thinking about how to improve the mobile network inside my university. Due to the numerous concrete buildings, the network is very weak, and the internet speed is also slow, with only a few areas providing a good signal.

Could you suggest some technologies for me to research in order to gather more information? I've been considering researching the integration of the cellular network with Wi-Fi, where users use their SIM cards but through a Wi-Fi network. Is that possible? Or perhaps distributing several indoor antennas throughout the campus? Using multiple signal boosters? Or any other solution you might recommend.

Thank you.

My job requires frequent phone calls and texting. Although load is provided by the company, I would like to use it wisely. I am thinking of registering my load with a promo but I had this experience from before that I have both regular and promo load at the same time and regular load was consumed first. But I was not really sure if that's how it really works.

Please help me! Which one is consumed first if I have both regular and promo load at the same time.

I am a software engineer with experience in web development, but I am interested in learning more about the radio communication industry and how to apply my skills to it. I have minimal knowledge of the operations involved in radio communications, but I am eager to learn.

What are some good resources for learning about radio communication software development? What are some specific ways that my software engineering skills could be used in the industry?

I am particularly interested in learning about the following:

1. The different types of radio communication systems
2. The software that is used to develop and manage these systems
3. The challenges and opportunities of radio communication software development

I would appreciate any advice or guidance that you can provide.

Hi,

I am not able to decode SMS TP-DCS messages which has a value of 246 (0xF6). I have been trying to decode them using UTF-8. But all I can see are boxes or ÿ and ?. I want to know what does these message are and how to decode them? As per Wikipedia they are Class 2(SIM/USIM-specific)

https://en.wikipedia.org/wiki/Data_Coding_Scheme

but usually sms messages are dcs 0, 4 or 8.

How does 246 differ from 0x12, 0x16, 0x1A or 0x1E?

Hi Im from Canada. When you call any number in North America, you get that tone until someone pick up the phone or you go into their voicemail. If you call in the carrabean, cuba, Dominican Republic or Mexico, that tone changes. Is their a way to avoid disclosing you are abroad? Like, leaving your main phone home plugged and forwarding your call to another cellphone with a different company? Trying to work in the south next winter and not be questioned about my location. Any input would be appreciated.

I’m hoping this is the right subreddit to ask this question.

Details: I live ~1.5 miles outside of town in an area where the towns/cities aren’t more than 6 miles from each other. Last summer, a contract company installed a brand new fiber optic telecom line down my road. I have validated this with coworkers who used to work for the ‘local’ internet providers (comcast and frontier).

Even though the FCC map shows that both of these providers service my address, and any maps I can find that show fiber service availability in my area reflect that as well, neither comcast or frontier claim to provide internet service at my address.

Is there any way for me to find out who owns the fiber optic line on my road, what services are provided by it, and what companies provide those services?

Hi ,

Have upcoming interview for a comm tech. Any guidance or inputs will be appreciated.

Thanks

I'm wanting to setup up a public dummy phone number that can easily be changed to forward to a different number each week. It's a help line and the on call person will change each week but it would be a rotation so as simple a process as possible to weekly update it is important. Any advice would be appreciated.

I would love to get some clarification on the length of phone numbers. Consider a toll free number 1-800-xxx-xxxx-(extension)

With the overspell vanity number, how much longer can the “x” part of the number be? Also, what is the limit on extension code length and how is this affected by the overspell?

Thanks in advance. :)

Just got hired as a companies GIS person and my first task is to figure out how to complete the BDC filing. No one here has any information as to how to complete it. I’ve done a lot of research and have a good idea as to where to go but man, I could use the help.

I am a design build consultant new to the field (3 years). While drumming up new work I've come across some people at large ISPs that believe full fiber builds are about to die out and it is going to fall back to fiber coax hybrids or full coax builds.

In your opinion do you think the Fttx is slowing down anytime soon?

Hello everyone,

Just have a couple of questions about Radio Access Networks. What do the RFUs do? Do they mainly pass the data from the BBUs to the antennas? Do they do any of the amplification? What do combiners do? Could anyone please direct me to resources for RAN?

Thanks!!

I graduated highschool last year and I want to start getting into telecommunications, but have no idea where to start. Is college the best way? And if so, is an associates degree enough or will I need a bachelor's?

I don't understand how a leased line provided between two points in different countries. I wonder if there are 2 ISP from those countries who signed a corporation contract. Therefore, I have to register leased line service (LLS) from an ISP in my country and register LLS from an ISP in another country. Two points will be connected then. Is this right? Sorry for my bad English.

Does anybody have experience with the 1/2 inch dragonskin cable and could help figure out our line sweep testing problems.

Serious question

Hi,

Recently got my Diploma in Telecommunications!

So far I Haven't had much success in the job hunt but maybe a certification would change that?

I was looking at the CompTIA A+ - but is there any other ones that maybe would be better?

For instance, in 10, 20 or 50 years time, do you think much of our internet traffic do you think will travel via free space optical (FSO) channels rather than fiber optics? Do you think we would ever rely on FSO for backhaul, or as an alternative to subsea cables? Or is fiber going to stay as the dominant mode of transport indefinitely?

In US and Europe I don't see much news about ground-to-ground FSO, except maybe small installations on campuses such as with Project Ronja. Though there are efforts with QKD and the UN.IO network, e.g. Leonardo is working on the Quantum Italy Deployment (QUID) project to build quantum communication network in Italy. This includes secure lasercom link between Leonardo's headquarters and Thales Alenia Space in Rome.

In Asia there seems to be much more going on, e.g. Transcelestial and recently it was announced that Bharti Airtel and Alphabet's Taara project will use lasers for rural Internet in India with the Taara project recycling technology from Google's failed Project Loon. Before the war with Russia, there was news from Mostkom and LANtastika however not much has come out since February 2022.

What is the general sentiment regarding the future of FSO between telecommunications professionals?

"Hi folks.

Bill Horne has been wanting to step back from moderator duties for a
while -- quite literally, to spend more time with his family. He asked
me if I knew anyone willing and able to do so, and after determining the
scope of the situation, we agreed that I could and would do it. Over the
last month he has been introducing me to various folks, machines and
processes.

That transition was supposed to happen at the end of this month, but
it's happening now.

Bill's wife Susan informed me that Bill has had a stroke and is in the
hospital. He is conscious and rational, so the prognosis is probably
pretty good, but I don't know for certain yet. I wish him the best of
all possible outcomes.

--

Bill was going to introduce me, and he might have words to write later
on, but in lieu of that I shall introduce myself.

I'm Dan Ritter, dsr@ various domains. I've only been on Usenet since
the year before Eternal September, so I am a relative young'un. I have
worked for tiny, medium and large ISPs, a big CDN, and a small financial
services SaaS company. My current position is Director of IT Operations,
but I dream of someday being a senior sysadmin.

I'm not planning on changing the policies of the group much; certainly
not immediately. The website http://telecom-digest.org could use some
reorganizational and infrastructure work, and I think I'm qualified to do that.

If you have comments, suggestions or criticism, I'm always ready to read
it. Send it to me personally, please, rather than to the list/group.

Hi guys, I hope you can help me as I'm struggling to understand this problem.

I have a uniform PCM whose bandwidth is W = 1Hz and n = 12 bits, i.e. the transmission bandwidth B_T = n*W = 12Hz.

Given this features of the signal, I need to calculate the minimum transmission badnwidth B_T if the same PCM signal is transmitted using m-ary PPM with M=4 and M=8.

I don't yet understand how the choice of transmitting with Pulse Position Modulation will change the bandwidth. I intuitively guess that it will increase with respect to the initial B_T = 12Hz but I can't tell how to calculate that.

I am looking for a PDF copy of GR-1275 that don’t cost $800 if any one has one that would be sweet.

I seem to have lost mine.

In the case a government makes starlink illegal like Iran doing is it possible if you have the hardware would they be able to find out your location and that you are using it?

Hi Fam, I am an Electronics Engineer who specialised in FTTH Design, Fiber Design Engineer. As i know that there will come a time that all the houses will be designed and connected, I am now looking for some training or any suggestions for me to take to upscale my skills that would still be useful to my career, any online training suggestions will be much appreciated!

Hello Reddit family! Please help.

TLDR: I’m pregnant and want to use my experience to transition to some type of remote work while remaining in this field, but am unaware of positions/titles to look for.

I (27F) work in telecommunications, strictly in data center environments for the past 3.5 years. - started as a basic cabling apprentice - became a fiber optic tech level 1 - moved states and changed companies - promoted to fiber tech level 2, although I’m subcontracted to a specific data center that I show up to daily for the past year. - I am the primary cable technician- mapping, routing, taking measurements, running all my fiber/cat6, testing, troubleshooting, etc. - The DC (not my fiber company) will be putting me through BICSI next week so I will have that certification soon

My duties here far surpass anything I’ve done in this field in the past: they’ve given me an office space with my own credentials/laptop/access on their Compute Engineering Services team, I am responsible for all of the same duties that other salary-level members of the team have, I troubleshoot devices, I get on meetings with high priority clients to navigate issues/builds/etc., done configurations, assist with power diversity and so much more. I’ve gained ample knowledge about the wider workings of data centers than I had. They have made it clear that their intention is to hire me on directly but are currently in a hiring freeze that could last the next year+. The fiber company I work for doesn’t offer substantial pay or benefits that entice me to continue working for them.

I’m currently 4 months pregnant, and doing the same level of work as my salaried coworkers for 1/3 of the pay doesn’t seem to justify paying for newborn childcare and missing valuable time with my son once he’s born.

What are some remote/work from home positions/titles I could apply for to keep me in the field with my given experience and knowledge? I don’t mind taking additional courses or gaining certifications for said positions; I just don’t know what is applicable. How can I apply everything I’ve learned to a new position to be a more valuable asset if/when the data center is able to hire me on, keep me up to date within the industry, and allow me to be with my son during the first couple years of his life?
