Over the past decade telecom industry has evolved tremendously, especially mobile data. GPRS, 2G, 3G and 4G, the data speeds have improved drastically. But the call quality is still stuck there. Poor voice quality, call jumps and call cuts are still haunting users.
These days we are hearing VoLTE network which promises to improve voice call quality. But, what is VoLTE? How VoLTE works?
LTE stands for Long Term Evolution, which is a standard for 4G network. VoLTE stands for Voice over Long Term Evolution, which means voice call over the 4G network. Unlike typical voice calls, on VoLTE call gets routed through 4G network. Which means your voice call gets converted into data packets and sent via data network.
We know 4G speeds are really good, so there will be no data packets loss. Thus we can achieve high voice quality on the call. Also VoLTE software is optimized to eliminate background noise thus user experiences clear voice even if the caller is in pretty noisy area. These calls are also called as HD calls. We can also make HD video calls on VoLTE network.
Everything looks fine, but for now there are few limitations with VoLTE. In order to experience VoLTE both the caller and receiver should be on networks which support VoLTE. Even if one person’s network doesn’t support VoLTE then normal voice call takes place.
The other thing is, in order to experience VoLTE you should have a VoLTE supported 4G smartphone. Otherwise, even if your network supports VoLTE you can’t experience HD call. Jio is the first VoLTE network in India. Airtel and other network providers are planning to rollout VoLTE by the end of 2017 or in the 1st quarter of 2018.
VoLTE is the future of telecom industry. So next time when you buy smartphone make sure it supports VoLTE. For now you don’t need to port your number to VoLTE network, because in coming months your network provider will also rollout VoLTE services.
