Telecom Network is the one which everyone uses these days, yet not many people know what it is exactly behind the scenes. Many of us have familiar with famous Gs like 2G, 3G, here G represents generation. 2G stands for 2nd generation, 3G for 3rd generation and so on.
1. Gs at network level
When they say 2G, 3G, 4G and 5G, these mainly represent the features of radio network. The backbone network is not called with Gs. However backbone network also changes with each generation of radio network. There is a international body ITU-T which sets the guidelines for upcoming generation. If a given technology meets the criteria then it is qualified to be G of that period.
2. G doesn't mean all network
As each generation (Gs) progress, backbone network also evolves accordingly, however it is not necessarily happen at the same time. Backbone network evolution might take different timeline.
When we say evolution, it means supporting the speed, features with each generation of network offers.
3.
Many might get wondered by the fact that, Mobile network is wireless only till the base station. From the base station, all call and data will be processed on wired/optical network. When a person calls from a cell phone, signals travels to base station via wireless radio network, then base station carries signal over copper cables or optical fiber to switching systems. Switching systems will determine the where call has to be routed to reach the destination user.
4. On the switching network side there will be mainly 2 sub networks, one will cater voice services another will cater internet services. Voice network has altogether different architecture than internet network. This gap is narrowing down now, as most of the services are provided over internet services. Within voice network there is TDM (Time Division Multiplexing) network and IP network, voice calls could travel through both these networks when you make call.
5. You might be wondered which generation the landline phones belong to. This is a slightly different story, as landlines are not so popular now, there is no rapid changes in this sector. Yet we have a evolution in landlines, which is as follows
a. POTS (Plain Old Telephony Services) also called PSTN (Public Switched Telephony Network), this offers only voice services.
b. ISDN (Integrated Services Digital Network), this network offers integrated Voice, Video and Internet services on a subscriber line. Voice and Video conferencing was the major service offered on this network.
c. VOIP (Voice Over Internet Protocol), VOIP network offers caters wide range of services. VOIP operates on internet protocol which makes it flexible to implement. Through VOIP, it becomes easier to connect. One of the major advantage of VOIP network is, you can login using multiple devices at a time and answer/make call from any device. Even soft phone (software application) can be used. VOIP opens a whole new level of service compared to earlier technologies.
