How Exactly Does Wireless Mobile Telecommunications Technology Work?

09/25/2016 1:04 PM

Dear community,

As far a I know about mobile networks (some basics from a Communication Networks University course), coverage is based on the cell technology. I believe each cell is gaining capabilities over time: GSM, 2G, 3G, 4G. But I have been wondering,

Do you know if cells are also losing them over time? If that is the case, for how long do you think the 3G will last until companies start to remove it (from the main cities in Europe, mostly Spain)?

Best regards.

PD: I am asking this to know if my 3G Samsung Galaxy S-III could work for a few more years (it is already 4 years old). And finally, I have been thinking about upgrading to the CAT S60 phone, but I read that 4G does not work on it. It may be because it is not on 4G coverage so it uses 3G, however, could you link me some technical test results (microchip information) as a proof of it having 4G?

Those links may be great to understand how it works in theory (something I already have some knowledge about), but I cannot find any practical information for my question.

Can 4G cells lose 3G capabilities (anytime soon)? Or, if 3G cells and 4G cells are not the same, while adding 4G cells, are 3G cells removed?

I tried to google these but it does not work.

The most recent time when new technology was completely incompatible with old technology was the switch over from analog to digital television. When this happened there was plenty of warnings to the public that their old equipment would be useless trying to directly capture signals and reproduce images. No such warning has been made in mobile communication. Some carriers are starting to drop analog voice communication due to a lack of traffic. but 3G is not analog voice communication. Now with the enormous amounts of data a 5G link can distribute I do see a 3G machine becoming useless with the tsunami of data needed for each app.

Could it not still make a telephone call, and be used as a local calculator, or stopwatch?

Hey, how exactly is a rainbow made?

How exactly does the sun set?

How exactly does the posi-trac rear end on a Plymouth work?

It just does!
