Verizon is enhancing its USA-wide Cat M network for IoT services. With the introduction of voice capabilities, the network is able to support a broad base of IoT services with more features.
First introduced in March, 2017, the Cat M network provides scale, coverage and security for users seeking wireless access for IoT products.
The Cat M network is now capable of providing voice access and will serve applications using fixed IoT voice services, such as alarm panels with communications components. The mobile voice service is enabled through a feature called CMM, for connected mode mobility, currently being deployed with expected completion within the next month.
CMM improves data transfers and handoffs, allowing for seamless transitions when using mobile voice or latency sensitive data. With the completed deployment of CMM, the Cat M network will support IoT services requiring less power, extended battery life, and either fixed or mobile voice connectivity.
“Considering the wide-ranging requirements of IoT in the marketplace, Verizon is dedicated to having network assets to meet each of those various needs,” said Bill Stone, vice president of network planning at Verizon. “A single, one-size-fits-all network for IoT doesn’t give customers the choices they require.”
IoT requirements vary in data rate, battery life and scalability. For small IoT services with data rates below 100kbit/s, NB-IoT Guardband technology is appropriate. For medium data needs, Verizon has a nationwide Cat M network now with voice capabilities. For larger IoT services, Verizon’s nationwide Cat 1 network fits. And for IoT services with extra-large data needs, Verizon has an LTE network.
“We are committed to collaborating with companies like Ericsson and Nokia to continue to develop the IoT ecosystem and ensure customers are able to get the network access and support that best suits their needs,” said Stone.
Verizon Communications, headquartered in New York, generated $126bn in 2017 revenues.
