What’s the Difference between VoLTE and VoIP?

With the rise in demand for better communication technology, VoLTE (Voice over Long-term Evolution) and VoIP (Voice over Internet Protocol) have become critical solutions for seamless voice communication. But what are the key differences between the two? And how do they benefit users in different scenarios? Understanding these distinctions can help you make informed decisions about your communication needs

What is VoLTE?

VoLTE is a specific type of VoIP technology integrated into the LTE (Long-term Evolution) standard. It allows users to make voicecalls while simultaneously using the LTE data network. Unlike traditional voice calls, VoLTE services operate as data flows  within the LTE data bearer. This enables high-speed wireless communication with improved call quality for mobile devices and other data terminals.

What is VoIP?

VoIP technology enables voice communication over the internet by converting voice into data packets. These packets travel across the internet as regular data, making it a flexible and widely used option for both consumers and businesses. While VoIP benefits include cost-effectiveness and versatility, it often faces challenges like call quality issues due to a lack of prioritization for voice packets over other data.

Key Differences Between VoLTE and VoIP

1. Fundamentals of Operation

VoIP sends digitized voice as data packets across the internet. These packets are treated equally to other types of data, such as video streaming or web traffic, which can sometimes result in call quality issues.

VoLTE, on the other hand, prioritizes voice packets using IMS (IP Multimedia Subsystem) technology to ensure a higher quality of service (QoS). This results in clearer calls with reduced latency and errors.

2. Quality of Service (QoS)

VoIP lacks QoS protocols, meaning voice data is subject to typical internet delays and congestion. This can cause jitter, latency, and poor call reliability.

VoLTE integrates QoS features to control jitter, allocate dedicated bandwidth, and prioritize voice packets. This ensures superior voice transmission with reduced downtime and higher reliability.

3. High Definition (HD) Voice

VoLTE supports HD Voice, allowing for wider audio bandwidth and better sound quality, especially when both devices in the call are HD-capable.

With VoIP, achieving HD Voice is less consistent since it depends on the internet connection and the devices used.

4. Technology

VoLTE is purpose-built for 4G LTE networks, providing faster connections and more efficient communication compared to traditional cellular networks.

VoIP can operate on both 3G and 4G networks, making it a more flexible option for areas without LTE coverage.

Why VoLTE Matters Today

VoLTE technology sets a new standard for voice calls by combining high call quality with efficient use of network resources. Here are some standout VoLTE benefits:

• Exceptional Call Quality: Rated higher than traditional VoIP or even high-definition Skype, even in congested network conditions.
• Battery Efficiency: VoLTE calls consume fewer resources on both devices and networks, resulting in extended battery life for users.
• Resource Optimization: VoLTE allows mobile operators to run more efficient networks while delivering superior voice services.
• Faster Connection Time: VoLTE eliminates lag, providing quicker call setups and seamless communication experiences.

When to Choose VoIP

While VoLTE thrives in 4G LTE network environments, there are scenarios where VoIP benefits outshine VoLTE:

• Global Connectivity: With its ability to run on both 3G and 4G networks, VoIP is ideal for international businesses or areas without reliable LTE coverage.
• Cost-efficiency for Businesses: Many businesses opt for VoIP solutions for their affordability, flexibility, and wide array of collaboration features.
