i am confused with this video. I though there were no wires with antennas but in the video, it shows that there are wires connecting one antenna to the buildings to the other antenna. How is that?

Answer 2

the drawings are correct, but they are much too simplistic to show the how and why cell towers work. If you think of a television set, the antenna on the tower has a lead-in coax wire that connects to a TV set in the building. a cellphone is 2 way, it simultaneously transmits and receives, so there is a second antenna and coax that connects to a transmitter in the same building. if you think of how a landline telephone works, it connects to a central office where switching is done. well the building at the base of the tower acts like a telephone except instead of the handset where you talk and listen, it connects to the receiver and transmitter that make the radio connection to your cellphone.



if you call a normal telephone from your cellphone, that switching is done at the central office. if you call another cellphone, it still goes through the central office but this time the switch is to another tower. at the base of the tower is like a landline telephone which automatically picks up the call, and then operates just like your cell tower works, with transmitter, receiver, 2 antennas and coax. Two towers that are connected this way by central office is called a trunk system.

Answer 3

Yes the cell sites are connected to switching centers. Sometimes using wire, fiber optics or microwave facilities. The wireless part is between the cell site and the users cell phone.

I presume which you haven't any longer have been given a cable service. purely connect the antenna to your place cable gadget the place it enters the abode. in case your place is quite under pressure for cable the sign would be accessible everywhere there are jacks.
