Voice over Long-Term Evolution, or VoLTE for short, refers to using 4G/ 5G LTE networks to make calls. In the past 2G and 3G generations, voice communications were sent individually via packet-switched networks while data traveled over different networks. Often, these different paths led to inefficiencies. In contrast, VoLTE combines these two channels to allow voice and data to travel across the 4G/5G LTE networks. This technology offers several advantages because audio calls are managed similarly to other data transmission methods, including enhanced call quality, faster call setup times, and the ability to use data services during a call. In this blog, we will explore how VoLTE is used in IoT cases, such as smartwatches, alarms for the elderly, emergency phones for lifts, and push-to-talk (PTT) radios.
Smartwatches
For smartwatches, VoLTE is a game-changer. These devices are designed to offer convenience and connectivity on the go, often without the need to carry a smartphone. VoLTE enables high-quality voice calls directly from the smartwatch, ensuring clear communication. Besides, it allows the device to maintain a slim profile by eliminating additional components required for traditional voice calls. This integration enhances the user experience, making smartwatches a more viable option for standalone communication.
Alarms For Elderly People
In the case of alarm systems designed for the elderly, reliability and clarity of communication are paramount. VoLTE provides a clear advantage with its high-quality voice transmission, ensuring that emergency calls are both swift and crystal clear. This can be life-saving in scenarios where every second counts. Furthermore, since VoLTE operates over 4G/5G networks, it offers more extensive coverage than traditional voice services, meaning that help can be summoned even in areas where the signal strength for older technologies might be weak.
Emergency Phones For Lifts
With ASDL lines being phased out, VoLTE is the perfect technology to replace it and lifts emergency phones are a critical safety feature. With VoLTE, these phones can connect calls faster and with better sound quality, which is crucial during emergencies like when the lift stops working. VoLTE ensures that lift emergency communication systems remain operational, leveraging the widespread coverage of 4G networks and enhancing their reliability and functionality.
Push-to-Talk Radio
VoLTE has significant advantages over traditional radio frequencies, particularly in terms of signal strength and quality for push-to-talk (PTT) services. PPT radios are typically used in different areas; sometimes, the radio frequencies struggle to get signal. VoLTE provides clear, continuous communication over great distances, even when radio frequencies could have trouble operating. This helps teams stay linked no matter where they are, which is especially helpful for sectors like construction, wildlife conveyancing, zoos, security, and event planning that depend on immediate communication.
