What is VoLTE and LTE-4G
Today our topic is what is VoLTE and LTE –4G very important topic for all of us because we are using mobile devices so important to know about this technology maximum people have confusion in VoLTE, LTE 4G so today your concept will be clear without any doubt if you have no technical knowledge don’t worry without going in technical details you will understand this technology if your are using VoLTE mobile you can see in your mobile near network tower indication strength it is written as VoLTE,LTE 4G, 3G,2G,1G in all these technologies peoples have confusion so today we will discuss all these technologies and their concepts so lets start our first question is what is 1G,2G,3G,4G LTE ?
1G,2G,3G,4G LTE here G stand for generation which change after some time whenever a big change happen in technology then this generation changes hence this G is generation changing due to development in technology as for example right now we are using 4G but next generation 5G is coming soon then will use 5G so first we will understand 1G.
What is 1G ? it came in 1980 the signal was using Analog and only calling since using analog signal so voice break was maximum some part of signal was got and some part of signal was lost because analog signal became weak as distance travel and also effected by noise weather and cable losses analog signal work on calculation method not accurate value signal has no more energy and can’t travel long distance suppose you called someone 500 m far from you can’t listen you analog signal losses energy as distance travel and that time there was no more network towers available after 10 to 12 years 2G technology developed.
What is 2G? digital signal sms and internet low speed feature available voice break long distance communication problem was removed in this technology now we ae able to send text message in the form of digital signal and was received at destination without any losses this was achievement of digital signal but internet speed was very low not able to download big files and was very costly so that normal peoples were not getting uses of internet this was disadvantage of 2G technology after that 2.5G came at that time youtube came in picture but at this time buffering was maximum to download video maximum time taken hence peoples were not getting more advantage of 2.5G after that 2.75G (EDGE (E) came in picture speed was 128kbps in this technology some speed of internet increases video buffering reduces even at this time internet was costly maximum people was not getting advantage of internet but this time people were starting watching video on youtube and youtube getting famous among the peoples now it was fast internet connection of 2G network even those people using 2G connection at present if they connect internet then in mobile shows written E means EDGE fast internet connection of 2G network now came 3Gwhat is 3G ? video calling speed 2mbps peoples were knowing this technology as video calling now peoples were getting good internet speed and watching video easily and coast reduces normal people was able to use internet now 4G LTE came in picture.what is 4G LTE ? this is not 4G it is actual LTE(long term evolution) after 3G it was taking long time to develop 4G technology so in between this a speed was fixed and was announce if technology will achieve this speed then will be called 4G LTE ( HD video calling, HD live TV ) remember it is not 4G you can say on the way of 4G but below the level of 4G here high definition video calling and watching live TV without buffering here internet speed is very fast.
Now important point all above technology calling method was same now lets understand the calling method of 2G,3G,4G LTE telecom companies focuses on internet data only but not cared about calling hence see call and data processing .
