AT&T, Ericsson, and Qualcomm Technologies Inc. have successfully concluded the demonstration of Voice over LTE (VoLTE) call for Internet of Things on existing mobile network infrastructure. This is the first successful trial of the technology, and will open up a new vista of possibilities in the connectivity domain.
The demonstration utilized one of Qualcomm Technologies MDM9206 LTE modem and Ericsson’s LTE Radio Access Network along with its other core networking infrastructure and new software. The successful conclusion of this new communication technology shows its readiness to be deployed in commercial operator networks and in many fastest internet provider services.
Chris Penrose, President of IoT solution at AT&T said, “AT&T is proud to participate alongside Ericsson and Qualcomm Technologies to advance VoLTE support over Cat-M1/LTE-M. The ability to support voice services is an important feature to many verticals within our IoT portfolio, including our customers in the alarm and security industry, automotive, wearable’s and connected health markets.”
The new technology will be instrumental in extending mobile voice service capabilities to IoT devices. This opens up new opportunities in expanding to many areas and serve potential applications like wearable’s, security alarm panels, remote first aid kits, digital locks, disposable security garments, and other IoT applications and services. This can have numerous advantages for enterprises by allowing them to make voice calls while also extending the operator’s mobile network capabilities through the IoT system.
There are many other advantages of these CAT-M1/LTE-M enabled IoT devices as well, lower power consumption and costs, excellent coverage, and good connection dependability being some of them. Due to the existing leading LTE coverage and voice communication capabilities by internet providers, operators can deploy it in a range of applications in smart cities, logistics, medicine, transport, etc.
Anders Olin, Head of Network Applications, Business Unit IT and Cloud Products at Ericsson said, “With this successful demonstration of Cat-M1/LTE-M also supporting VoLTE voice calls in IoT devices, we are providing more value to operators and users. The benefit of basic human communication blends perfectly into the IoT environment. Supported by our radio and core portfolios, it will now be feasible to globally deploy voice services for IoT cost-effectively for all kinds of industries and different use cases.”
In addition, the uptake of VoLTE is predicted to accelerate to 3.3 billion by the year 2022 and accounts to more than 60 percent of the total LTE subscriptions. It is estimated that there will be around 18 billion IoT devices connected worldwide by 2022.
