IoT systems provider Semtech has expanded its AirVantage Smart Connectivity Advanced solution to include VoLTE service in the US and Europe. Semtech says that enabling VoLTE through AirVantage will open up more seamless usage of data, SMS, and voice services for smart city applications and devices in many parts of the world.

Semtech offers VoLTE through its Smart Connectivity Advanced solution in over 40 countries and territories, including in the US and Europe. The company plans to expand in Asia Pacific and Latin America.

Smart Connectivity addresses complex global deployments, network coverage, and regulatory challenges like technology sunsets and permanent roaming restrictions through a single global SIM. This provides access to more than 600 networks in over 190 countries and territories. Built on 4G LTE, the Smart Connectivity Advanced solution also supports voice services through circuit switched fall back (CSFB) on 2G/3G networks in countries where the technologies are still available.

“Voice services are essential for critical use cases that keep people safe and secure, through smart watches and other monitoring devices in assisted living facilities, emergency call mechanisms in elevators, tracking and calling applications in freight and fleet management for lone worker safety, and entrance monitoring with access control and intercoms,” said Rupa Datta, senior director of Semtech’s managed IoT services. “It is crucial to ensure that these devices have reliable connections. The Smart Connectivity Advanced solution is future-proofed, which means that customers who subscribe and use voice service can expect to enjoy the expanded coverage as we grow our resilient, global footprint.”
