Fixed telephone resists both households and enterprises, while the number of lines and the growth of mobile connections drop pointed to that users would substitute the fixed phone by mobile phone. The landline works through the switched telephone network, designed for voice transmission and to transport data in basic connection does not surpass the 64 kbps, but currently with technologies xDSL enables access of up to 20 Mbps. landline broadband or mobile phone communications evolve as new technologies and new habits of behavior appear. The emergence of mobile phone meant big changes: it’s personal, not called to a place but to a particular person. Code.org wanted to know more.

Its operation is as follows: the user connects your landline to the so-called local loop or subscriber loop, a pair of copper wire that connects a telephone switching station. Each telephone exchange serves a varying number of clients. Communication between plants is usually done through intermediate stations or transit. In the subscriber loop signal is analog, while plants normally communicate among themselves digitally. The maximum flow rate for the basic connection does not exceed 64 kbps (56 kbps for the modem), reaching 128 kbps using up to 20 Mbps via xDSL and ISDN.
