How jio technology works?


Reliance jio is an infocom companylimited or jio is an LTE mobile network operator in India. It is a wholly owned subsidiary of reliance industries headquartered in Mumbai which is in Maharashtra that provides wireless 4G LTE service network and not depending on 2G or 3G services. It is the only VOLTE-only operator in the country which lacks legacy network support of 2G and 3G with coverage across all 22 telecom circles in India.

VOLTE is the abbreviated form of voice over LTE and is a new protocol for transferring voice data over the LTE network. While 2G and 3G networks are circuits which based, 4G or LTE networks utilize packet switching. If a person makes a call through 2G or a 3G network, a certain amount of network bandwidth is assigned to that call as a pipeline, and that does not terminate till the call ends. Here in the VOLTE network, the voice calls are broken up into packets of information, sent over the full data pipeline and then be constructed at the receivers end.



The impact occurred due to that is voice of information can be carried over a higher bandwidth pipe, resulting in better call quality. It is essential to understand that LTE is a wholly IP based communications protocol. Presently the existing carriers have all 2G,3G and 4G setups on their network, allowing data to pass through the 4G band while pushing calls through the 2G/3G band.

LTE technology

VOLTE is a way to convert voice calls into digital packets and transmit them over an LTE network. In fact, VOLTE is a subset of LTE technology. Traditional voice networks use a technique called circuit switching. Here, the actual circuit is voice-only. The signal must go through several switches to connect to the final receiver. On a telecom, a switch is a device that receives an input signal from a mobile phone and outputs it to the appropriate destination. Telco has been able to place switches for many years to call from one point to another. The problem is that the switch can not be used for any traffic while the phone is connected. In addition, calls must be routed through switches on such networks through fixed routes. The circuit type of a switched network is traditionally used only for voice calls because it is not suitable for data.
