Verizon carries first live over-the-air VoLTE call on US LTE Cat M1 network

For the first time, Verizon´s LTE network has carried a live over-the-air LTE Cat M1 VoLTE call, laying the foundation for the next generation of IoT connectivity, the company said.

By proving CAT M1 VoLTE technology works on a production network, Verizon, along with Ericsson and Qualcomm Technologies Inc., demonstrated that the reach of Cat M1 can extend across Verizon´s US LTE network, fostering growth opportunities for IoT companies and developers, whether they are focused on data-only or voice-enabled products.

In addition to its ubiquity, Cat M1 brings efficiency, extended coverage and security advantages to the market. Cat M1 is designed for devices that require extended battery life, which enables a variety of applications from water meters to wearables to asset trackers and consumer electronics.

This technology also allows signals to better penetrate walls and floors to reach devices located in remote locations. Cat M1 is a 3GPP-based technology that is deployed on licensed spectrum, owned and operated by one entity, which means IoT traffic traverses a more secure network.

For the trial Verizon used Ericsson´s commercial network infrastructure deployed on the Verizon network and incorporated the Qualcomm® MDM9206 global multimode LTE modem, whose chip is enabled for Verizon´s ThingSpace IoT development platform.

Verizon has been a leader in Cat M1 technology. In 2017, the company was the first operator to deploy Cat M1 nationwide and in 2016, Verizon was the first service provider to launch a commercial Cat M1 network.

Verizon Communications Inc. (NYSE, Nasdaq: VZ), headquartered in New York City, has a diverse workforce of 161,000 and generated nearly USD 126 billion in 2016 revenues.
