Self-organizing edge intelligence ensures that Cel-Fi SOLO does not interfere with other indoor wireless products such as Wi‑Fi routers, Small Cells and Distributed Antenna Systems (DAS). High speed Automatic Gain Control ensures that Cel‑Fi SOLO is unconditionally network safe and enables more simultaneous calls and higher data speeds.


The Cel-Fi WAVE App is designed for users to activate, manage and troubleshoot the Cel-Fi SOLO. The app connects to the device via Bluetooth and is available on smartphones and tablets. It is globally trusted and built on carrier-grade security. The device data is synced to the WAVE Portal which allows for additional data modeling and reporting.
