What protocol do cell phones use to communicate with cell towers? Can this be emulated?

This is one of those questions with one really simople answer and one REALLY complicated one.Simple:You have heard of "GSM" or "LTE"?Those are the protocols.There are probably five in general use: GSM, cdma, WCDMA, TD-SCDMA and LTE -- all with lots of variant, options and releases.These are how a cellphone talks to

Could a Cell to Cell network function and eliminate the need for cell towers and cell phone companies entirely?

That would be a "mobile ad hoc network".There has been an IETF MANET working group for some time, and they've published a number of RFCs (informational, experimental, and standards track) that address many aspects:Mobile Ad-hoc Networks (manet)Quite a few of those are still informational though, so quite a

Does a cell phone transmit to a cell tower then to a satellite or straight to a satellite?

Cellphones never transmit or receive signals directly to or from satellites. Most cell towers are interconnected using fiber optics or microwave links. Only in cases of remote locations in which it doesn't make economical sense to lay fiber is satellite used for the

Where can I find a map of cell phone towers?

You will probably find cell site locations at your national telecom or spectrum regulator.In Europe this sort of information us available via the overall Open Data initiative.In USA I think this is available at the FCC.Not sure about other countries but will update answer if readers post URLs in comments to this answer.

Do GSM cell phones transmit anything while looking for a cell tower to connect to?

The attach process used by 2G, 3G and 4G phones is more or less the same.Step1 has the device scanning all potential base station carrier frequencies looking for special synchronisation signals so that it may start receiving information. This step consumes battery as the phone must tune across many frequenies in multiple bands and look for valid signals from

How does a cell tower hear your phone when your phone is only transmitting weak signals at very low power?

Fahad Hameed Ahmad , thanks for your A2A.Who said that a cellphone is transmitting weak signals at very low power?The highest power a WiFi antenna transmits is, generally, around 100mW or 0.1WattGSM can transmit a signal up to 2W, or 20 times the power of a WiFi antenna.Outdoor WiFi antenna

How do cell phones connect to cell towers?

Our cell phone is a transceiver (transmitter and receiver) and a cell tower is essentially the same. When we make a call on our cell phone, the signal gets picked up by the nearest tower in the cell you are in, which is then relayed to the tower nearest or inside the cell where the phone

Does a cell phone tower identify IMEI when a phone is connected to it?

Each Mobile has unique IMEI it is like identity card and gives many information like origin, model, and serial number...You cannot trace the physical location of a phone itself with just it's IMEI number, your cell provider can use the IMEI number to bring up the cellular phone number that it's linked to. If any person

Can cell phone towers transmit meta data to a transponder or a ground control unit?

How to find the nearest cell phone tower

There is additionally a mobile application called OpenSignal that is accessible for iOS and Android gadgets - obviously they likewise have a site you can utilize. This application can not just give a guide cell tower locations, however it likewise incorporates a helpful compass that focuses you toward the cell tower you're joined with.

Why does a cell tower transmit more power than a cell phone?

To cover a larger area. The cellphone doesn't need such power because the receiver (the cell tower) uses more sensitive antennas to intercept also weak signals coming from a phone with little power.When we talk about little, we should still remember that a GSM phone transmits using a 2Watt

How does cell tower triangulation works?

You may have noticed that the antennas on a cell tower are always arranged in a triangle. There are some sound technical and economic reasons for this, but we won't go into that here. But it does mean that a cell tower can tell from which of the three antenna arrays it is receiving a signal. Each of the

Do cellphones transmit their battery level data to cell phone towers?

Its almost impossible to gain access through kernel level of each and every smartphone for the tower or the service provider you can say. Well...if this happens than it will be harmful for your privacy. I dont know how this

How often does a cell phone ping the towers?

I already seen a tv shows about this question and if I remember, its something around 10 requests/seconds. It's important also that the signal are strong to get a strong signal from your cell phones. If the tower is not close, you could get a low signal and your interlocutor could hear some noise.

Does a cell tower transmit up?

As other answers: not really.However, as an amusing twist.ZTE has built a chain of basestations in China explicitly & purely to transmit up: they enable normal cellular service on flights between Beijing & Shanghai.(I'm not quite sure how they cope with Doppler? Planes go faster than usual 3GPP requirements? Maybe the fact it is simple line-of-sight makes

A2A Towers are cheaper? It may be more expensive to use a cellphone if they used satellites instead.If we used a geostationary satellite, all of which are 42,164 km up (or double that distance round-trip) there would be a delay in light-time of 0.28 seconds for two-way communication. Not to mention the satellite dish ball-cap or umbrella
