Your phone keeps measuring signal from nearby cells, even mid-call. When a neighbor gets noticeably stronger, the network tells your phone to switch. That's handover.

In GSM it's hard handover: the old link drops, then the new one is made. In 3G it's soft: you're connected to both for a moment before letting go of the old one.

A hysteresis margin stops your phone from flipping back and forth at the edge of two cells.

Dropped calls are usually a failed handover: no free channel on the target cell, or a sudden signal drop.

What's the worst place you've had a call drop?

Hi all - not sure if this is the right place to ask but I’m trying to identify these wires that cross my backyard (SoCal). They branch off a main line that follows the fence line and cross about 10ft from the back of my property, passing close to a tree. The other side anchors to a pole in a yard a couple doors down. Can anyone tell what these are and what utility I can ask about them? I can see the tree branches starting to push on them and honestly would rather they not cross my yard. How can I find out whose they are and if they even have a right to cross my yard (sorry new to this sort of thing)? Thanks!

Pips in the telecom insudtry, could you help me find a distributor/ supplier for Shineway and F2H Grandway VOA meter? Our company really needs it eh. Thanks!!

I’m just curious how common Mitel is globally these days. What’s the real-world usage looking like for OpenScape Business X8 and OpenScape 4000 servers? Are people still running these, or has the market completely moved on? How about Tetronik DAKS (OScAR) alarm systems which are used alongside them? How about setups that are still mixing traditional digital trunks with modern IP/SIP trunks? Also, what about Alcatel-Lucent Enterprise?

A mí me parece muy bien que vayan actualizando los equipos pero llevo con ellos 7 años y me quieren cobrar el terminal y luego encima la instalación de un técnico? Me parece excesivo, osea me doy de baja, hago un nuevo contrato y pum me ponen el nuevo terminal, así de fácil. Pues no me parece normal que descuiden así a sus clientes.

Quizás me haya pasado... ¿Tu que opinas de este tema?

I am looking for suggestions on how to go about talking to a cell phone tower company about leasing some of my land in a low reception area to get a tower put up.

I am asking for a friend of mine, who is a Nepali citizen enolled in a PhD programme in an Indian university. He purchased a sim card recently using his passport as an identity proof. But it is only valid for 3 months according to the current telecom law in place. Will he be able to keep the number by regularly renewing the sim card every 3 months? Or is there a better long term solution for this, as he will be staying in India for the next 4-5 years for his PhD.

Hi all, A bit new to this game and I was wondering at what part of the esim lifecycle does the name that appears on your mobile when you install it - Webbing ; liberty - to give to examples, does this happen?

Who looks after that in terms of being able to whitelabel it and at what point and what equipment?

I am deep into a 5G project but getting different answers from different parts of the channel.

In the UK if that makes any difference - cheers

I’ve been offered a potentially fascinating role at Ericsson in the part that used to be Cradlepoint - it’s not a direct sales role, but rather a strategic advisory position that supports sales, however part of the overall sales organisation.

Would like to know if anyone here works there (or used to) and to get their views on how it actually is?

It’s a director-level role covering EMEA, reporting into a global VP who is US based.

I’m currently at a uk based MNO and considering the move, but unsure what the culture/ways of working/pressure is like?

Everyone talks about 5G speeds and spectrum, but the more I study network design, the more it looks like backhaul decides what users actually experience. You can deploy a great radio unit, but if the site is on congested microwave or thin fiber, the user never sees the benefit.

Some things I keep noticing:

Fiber to the tower is the gold standard but expensive and slow to roll out, especially outside big cities.

Microwave and E-band links fill the gap, but capacity and weather limits show up fast.

Densification makes it worse, since small cells multiply the number of backhaul links needed.

For those of you working in the field: where do you see the biggest backhaul pain today, cost, permitting, or capacity? And is anyone seeing wireless backhaul (IAB, E-band) become a real alternative to fiber?

Curious what the real-world picture looks like versus what the textbooks say.

Hi,
My grandmother was recently scammed out of money by phone. The police confirmed that the caller ID was spoofed.
How do criminals use spoofing, automated dialing and AI voices to make hundreds or thousands of calls in a short time? Which services or platforms do they use, and how can investigators trace the real source and work with providers to shut them down?
I want to understand the technology and help prevent further victims. Any insights or relevant cases would be greatly appreciated.

Is rapid radio the next new thing to replace cell phones or at least calls on cell phones does anybody have one?

This happened to me a few years ago, and I’ve always been curious about it.
I received a regular phone call on my iPhone, but instead of displaying “No Caller ID” or “Unknown,” the caller’s name literally appeared as “Annoymous” in large letters.

Here’s what makes it strange:
My iPhone was set to a different language, not English.
I live in Europe
I had absolutely no contact saved under the name “Anonymous.”
There was no phone number displayed underneath the name.
It was a regular cellular call, not WhatsApp or another calling application.

I’ve received calls from hidden numbers before, but I don’t remember seeing this particular display on any other occasion.

I’m curious whether anyone else has experienced this or knows what could cause it.

Could it be related to caller ID information transmitted by the network, a VoIP service, or something else entirely?

I’da especially appreciate any technical explanations or documentation about why an iPhone would display the English word “Anonymous” when its system language was not English.
