WebGSM is a circuit-switched system that divides each 200 kHz channel into eight 25 kHz time-slots. GSM operates on the mobile communication bands 900 MHz and 1800 MHz in most parts of the world. In the US, GSM operates in the bands 850 MHz and 1900 MHz. GSM owns a market share of more than 70 percent of the world's digital cellular subscribers. WebThe call flow in the LTE network is unique among mobile communication standards and represents the signaling and sessions established across the network. The LTE call flow navigates over the elements of the network going through certain steps in order to complete its end-to-end signaling from the user equipment (UE) all the way to the rest of ...
