Devices are doing far more than sending data: they’re actively engaging with humans, control systems, and emergency services across healthcare, automotive, public safety, and smart cities. In this context, Voice over LTE (VoLTE) is emerging as a critical technology for enabling high-quality voice and data connectivity simultaneously
What is VoLTE?
VoLTE is a technology that lets your phone make calls using the 4G internet network instead of the older phone network. This means your calls are clearer, connect faster, and you can use the internet while talking on the phone. Before VoLTE, phones had to switch to older, slower networks like 3G to make calls, but with VoLTE, everything stays on 4G, making communication smoother and more efficient. In simple terms, it’s like upgrading from an old landline to a high-speed internet call built right into your phone
Perhaps more than anything, VoLTE represents a mindset shift. For too long, IoT devices have been seen as silent data collectors; with VoLTE, they become communicators capable of real-time interaction, and instant response. Whether it’s a sensor that can speak when something’s wrong, a vehicle that can call for assistance, or a remote staff member dialling into augmented infrastructure through a wearable, each scenario moves closer to real integration and to greater impact.
What makes VoLTE useful for IoT?
Unlike traditional circuit-switched voice technologies, VoLTE operates entirely over LTE’s packet-switched infrastructure. What does that mean for your IoT deployment?
First, users experience clearer voice quality. No more distorted communication or dropped syllables during emergency communications or high-stakes industrial operations.
Second, voice and data can flow together natively, allowing devices like connected medical monitors or autonomous vehicles to talk and transmit streams of data at the same time. It’s truly simultaneous operation.
Third, it’s efficient VoLTE conserves battery and network resources through smarter packet handling, which is perfect for the small, power-sensitive devices populating our smart cities and smart fields.
One of the prime advantages of VoLTE is its support for Network Provided Location Information (NPLI) and event-based triggers. These are more than mere buzzwords: they enable devices to automatically call for help or switch to prescribed modes based on geographic location or triggered conditions such as a fall in assisted-living setups or an alarm in smart infrastructure systems. The importance of these capabilities cannot be overstressed in environments where every second counts.
Use case, building management – emergencies in lifts
VoLTE in lifts.
Many lifts have emergency phones that use mobile networks to call for help if someone gets stuck. As older networks are being shut down, using VoLTE ensures those emergency calls still work properly. It helps the call connect quickly and stay clear, so people can reach building staff or emergency services without delay, something that can make a big difference when time matters
