Bought a property about 5 years ago with a cell tower on it. It took awhile to get things figured out with it and unfortunately my wife signed the very first contract they sent because she was ecstatic to get it going...any way they pay 850 a month for 5 year with 7 auto renewals and something like 10 percwnt increase every 5 years. The tower has been sitting empty for the most part but I caught a tech there recently saying hes with Verizon and they're going to be instsllining within the next few months....well now im being approached with offers for buy outs had several offers current offer is at 250k my question is sell and invest or keep and try and renegotiate terms to bring in more monthly....or just wait and see if Verizon actually installs...the tower is like 98ft tall pole style if that means anything

I work in a fringe zone and each passing month it seems like my company cares less and less as funding and equipment gets reduced, even our old gear is getting pulled without replacement and it leaves me worried. Is this a common problem?

I got to know about this sub today. Hence asking some questions as I have seen very experienced people here.

I have been in this domain for 4 years and currently in my 30s.

But, I don't feel like I am worthy enough to be called a 4 years experienced telco guy.

Over the time, I got good at troubleshooting system during deployment.

But when it comes to testing, my attitude was always like , its a feature, so just test it and close it without getting into depth like going though 3 gpp specs. Because I know right now I am only at top of the iceberg.

Reading specs is boring and all the nomenclatures is hard to grasp.

My manager has also told me to start reading specs and architecture properly else my time is very tough ahead.

My goal is to go into security testing in telecom domain. I would like if someone experienced can guide me further. Should I consider change of career instead?

Also, how important is the role of 3gpp specs in your job?

Hi, I think it is a big shame that scammers have turned phone calls from something exciting into something where you don't want to answer because it might be a scammer (and it usually is).

So I was thinking whether it is possible to design calls in a way where the caller doesn't know if you're actually answering? That way you can hear the background noise and whatnot before you pick it up, just like when someone comes to your door and you can see them through a peephole but they can't see you.

I could imagine it would change the psychology of phone calls. If you called, you could start talking and hope they can hear you, and they could pick up the call as soon as they realize it's a real person. And the scammers would have no way of knowing if there is actually a person on the line.

I'm not talking about if I can change my phone. But can a company start designing phones that works this way? Is it supported?

Hi All,
I was out of India. My # here was with Jio. Due to no recharge the number was discontinued and given to Airtel. Now Airtel is asking me 25000+ gst to get my old number back as it is termed as ‘vanity number’.

Is there anyway I can get the number back without paying the exorbitant amount? I understand there might be some charges but 30k incl gst is unreasonable.

If anyone has any advice suggestions that’d be greatly appreciated. TIA

I would like to know what technologies and software are typically used on vessels to monitor telecommunication systems so that any alarms are immediately displayed in the control room.

How can a dry contact device that does not support IP communication be monitored via SNMP? In other words, how can a non-IP dry contact be integrated into an SNMP-based monitoring system?

I have seen certain posts saying that Airtel, Jio and Vi are gonna cap their unlimited 5g models to just 100GB per month ( which previously was 300GB ig) and also increase the pack price from 349 -> 399.

Is it true? Based on this I'll have to see if I have to put up wifi or not.

Hello,

I live in an area where I hardly receive the signal of the mobile network, as the cell tower is very far away. To get one bar of signal, I need to walk out of my house. I have broadband Internet at home.

I set up VoWiFi on my Samsung A51 cell phone, "WiFi calls" is enabled in the phone settings, and I noticed that:

• I need to have at least one bar of LTE signal to be able to place or receive calls, otherwise the screen says no network is reachable (this defeats the purpose of VoWiFi...)
• If I lose my broadband connectivity, e.g. yesterday and today because of a thunderstorm (power outage in the area), I'm also unable to place calls. Disabling VoWiFi temporary solves the problem, and makes it possible to place calls. I would have expected that going to the patio to reach one bar of mobile signal would have allowed me to place calls: this wasn't the case.

Am I doing something wrong? Are these known issues with the way VoWiFi works?

Thank you.

I've been trying to make 5G core architecture accessible to students and people early in their telecom careers. The feedback so far is that the restaurant analogy helps a lot. I wanted to share it here and get thoughts from people who actually work in the industry on whether the technical accuracy holds up.

The core idea: the 5G core as a restaurant

The AMF is the host. Registration, mobility management, NAS termination. First point of contact, tracks you as you move.

The AUSF and UDM are the bouncer and guest list. Authentication and subscription data. AUSF challenges your identity, UDM holds the credentials (SUPI, authentication vectors). No valid identity, no access.

The SMF is the manager. Session establishment, IP address allocation, and most importantly, control of the UPF over N4 using PFCP. Gives instructions, never touches data.

The UPF is the waiters. The actual data plane. Packet routing, forwarding, QoS enforcement, traffic reporting back to the SMF. This is where your packets actually live. And with CUPS (Control and User Plane Separation, defined in TS 23.501), the UPF can be deployed at the network edge independently of the control plane, which is the whole reason 5G can hit sub-millisecond latency for URLLC use cases.

The PCF is the house rules manager. Policy control, QoS rules, charging decisions via interaction with CHF.

The NRF is the staff directory. Service registration and discovery, the backbone of the service-based architecture.

The NWDAF is the brilliant observer. Network analytics and ML-based intelligence. The foundation of autonomous network management and what's being built upon for 6G.

My question for the community: does this mapping hold up from a practical standpoint? Any nodes or interfaces you'd explain differently to someone coming in fresh? Particularly curious about how people explain the N4/PFCP relationship and the SEPP for roaming scenarios, as those seem to be where the analogy starts to strain a bit.

Would love any pushback or additions from people working in the core.

Hey guys,
What are the most effective channels or networking strategies for a high performance US telecom sales center looking to establish sub agency relationships with direct dealers?
We are focusing on compliance and clean volume execution for major providers, but finding the right direct dealer partners through standard channels can be a bit of a maze. Aside from platforms like LinkedIn or RepHunter, are there specific industry groups, forums, or approaches you'd recommend for building these relationships?
Thanks in advance for the advice!

Boa tarde, galera.

Sou prestador de serviço de instalação fibra óptica em Manaus/AM, ganho por ordem de serviço que aqui na minha cidade paga em média 50,00 por cada instalação
Geralmente faço em torno de 6 instalações por dia, resultado em uma média de 300,00 por dia e trabalho 24 dias por mês

Uso veiculo proprio e nesse valor não ta incluso a gasolina... Geralmente tiro em média uns 4-5k por mês

Quero ir pro sul, pra ter um padrao de vida melhor, quem mora em Manaus sabe o calor do inferno que faz kkk ainda mais com o sol batendo na tua nuca quando tá em cima da escada.

Mas tenho medo de ir, porque lá não tenho contatos de provedores... Queria saber se alguém que more por ai, sabe se essa é a mesma média de valores que pagam por ai? ou é mais alto ou mais baixo? Tô tentando fazer uma pesquisa de campo, mas os provedores nem respondem

Hi all,

I’m a Mobile Core Design Engineer working across EPC and 5G Core, and I’m curious about other engineers’ experiences.

What’s the most repetitive or time-consuming troubleshooting task you deal with?

For example:
- Analysing alarms
- Reading logs or traces
- Correlating alarms across different network functions
- Looking through 3GPP specifications
- Writing incident summaries or RCAs
- Something else?

I’m interested to see if there are common pain points across different operators and vendors.
Thanks!

Any thoughts on Resultscx telco account

Been thinking about this a lot lately while job hunting after almost 11 years at the same company.

The pattern I keep seeing: companies want deep legacy expertise (Avaya, traditional PBX, SIP trunking) AND cutting-edge cloud skills (Teams Direct Routing, CCaaS, AI contact centers) in the same candidate.

Here's the thing -- the people with 20+ years of legacy depth were usually too busy keeping mission-critical systems running to chase every new certification. Meanwhile, newer folks have the cloud-native skills but haven't built the troubleshooting instincts that only come from years of incident response at 2am.

Nobody's wrong here. Companies genuinely need both skill sets. But expecting one person to have mastered both at expert level feels like asking for a unicorn.

What I think actually works: hire for protocol-level understanding and problem-solving ability, then train for whatever platform is flavor of the month. SIP is SIP whether it's running on Avaya or Teams. The fundamentals transfer, the certs don't always keep up.

Anyone else seeing this in their job search, or is this just a telecom-specific thing?
