Difference Between VoLTE and LTE:
What is LTE?
LTE stands for “Lengthy Time period Evolution”. In technical phrases, it’s an ordinary for high-speed mobile information communication techniques primarily based on its predecessors UMTS and HSPA. It’s a major leap in the direction of high-performance mobile information service that makes use of a distinct radio interface together with a slight core community upgrades. It’s the following stage of cell communications know-how (4G) developed and applied by “3GPP” (Third Era Partnership Venture), a consortium of cell communication associations.
The necessity for prime peak information charges with considerably larger bandwidth and flexibility in frequency finally gave rise to a brand new normal of high-speed cell broadband companies – LTE. It’s an excellent improve from the low-speed 2G normal (GSM) and 3G know-how, offering unmatched consumer expertise for long-term reliability. Owing to the next-generation connectivity and important upgrades to the unique 3G know-how for a extra simplified structure, the ITU-R determined to formally name it as 4G LTE.
The thought is to make use of a distinct radio interface because the LTE wi-fi interface wasn’t suitable with the 2G and 3G requirements. Additional, a simplified and redefined community structure was required that might scale back switch latency and nonetheless use some parts of the 3G structure. This provides rise to the 4G LTE which operates extra effectively and gives a lot larger information charges as in comparison with the 3G. It provides larger speeds and higher stability than the traditional LTE.
Theoretically, the downlink charges of LTE can peak at 300 Mbps and uplink charges at 75 Mbps, plus it permits for multi-cast and broadcast streams to tweak sign power and enhance bandwidth. As well as, it’s an IP-based packet-switched community that helps each IPV4 and IPV6. LTE relies on OFDMA (Orthogonal Frequency Division A number of Entry) to allow larger information bandwidths whereas nonetheless offering excessive diploma of resilience to interference.
What is VoLTE?
There was no help for voice in LTE natively, which finally gave rise to VoLTE, brief for Voice over LTE. It’s a a lot standardized system to make HD voice calling extra environment friendly and quicker than 2G/3G networks over 4G LTE. It’s a extra superior mobile information communication know-how which permits customers to ship voice and information over the 4G LTE band with out hampering the standard of voice. VoLTE is particularly focused at managing and bettering high-speed voice and information companies over 4G LTE networks.
In LTE, the voice high quality reduces whereas making voice calls with the info connection on, thus urging you to show off the mobile information to get pleasure from a greater voice name service. Some networks would robotically cease the info switch course of to protect the voice high quality over 2G/3G bands. Nonetheless, the mobile information gained’t intrude with the voice name service in case of VoLTE, permitting for uninterrupted voice calling companies even with the info connection on.
In technical phrases, VoLTE is an IMS (IP Multimedia Subsystem) primarily based community which helps packet switching. The info acquired from CDMA and GSM networks will get transformed to community packets earlier than the published. VoLTE is barely restricted to IMS-based networks, thereby simplifying interconnectivity for higher voice and information companies. It permits for a plethora of companies to run flawlessly somewhat than working completely different disparate functions concurrently.

VoLTE doesn’t do a lot of switching between networks frequencies, which makes name routing quicker than the community with normal 3G voice calls, making it useful for the tip consumer. It additionally permits for higher inter-network connectivity which finally takes loads of pressure at determined instances when the community is overloaded. It frees up the bandwidth by optimizing the LTE packet stream, making it gentle, thereby leading to superior voice calls and information companies.
Main Differences between LTE and VoLTE:
1. Voice High quality
LTE could or could not help voice and information companies on the similar time with out affecting the voice high quality, thus making it much less environment friendly than VoLTE networks, which alternatively, allow quicker voice name set-up. Each the customers will expertise an uninterrupted name session, if they’re on VoLTE networks, leading to seamless calls.
2. Information Connection
In LTE, the community will swap off the info connection whereas making voice calls, when you don’t want to show your information connection off whereas making a voice name in VoLTE. Whereas LTE is focused for rising information charges on the 4G bandwidth, VoLTE is focused in the direction of each voice calling and web information with out affecting one another.
three. Web Dependability
Web information needs to be enabled always so as to make free calls and it can’t be turned off. In VoLTE, alternatively, you don’t need to maintain the web information on to make free calls.
four. Name Set-Up Time
It takes roughly 7 seconds to attach a name on 3G networks, whereas connecting time reduces considerably if each the customers are related on 3G networks through VoLTE. If each are on VoLTE, it’s solely a matter of second.
5. Exterior Software program
Exterior software program is required so that you can make video calls on LTE networks corresponding to Skype, WhatsApp, Fb Messenger, and so forth. You don’t want any exterior software program to make video calls on VoLTE networks – you simply want your telephone quantity to video name anyone.

- There are such a lot of acronyms related to mobile networks with LTE and VoLTE being thrown round a lot, which are sometimes used within the context of selling. Nonetheless, each are utterly various things.
- LTE is the next-generation of cell know-how which provides excessive information switch charges over 4G networks. Theoretically, LTE helps obtain pace as much as 100 Mbps and add pace as much as 50 Mbps. The phrases 4G is synonymous with LTE.
- VoLTE, alternatively, helps each voice and information concurrently with out affecting the standard of different. In contrast to the LTE, even voice calls together with net looking are attainable over VoLTE networks. It means you’ll have the ability to make voice calls and surf net utilizing the info plan.
- VoLTE has fairly an edge over its LTE counterpart on many fronts corresponding to voice name high quality, HD video calls, battery life, name set-up time, and extra.
