About
Cellium Technologies is focused on providing indoor wireless connectivity solutions that support backward compatibility along with cutting-edge technologies designed to future-proof investments in cellular, Wi-Fi, and IoT networks essential to sectors including enterprise, retail, education, healthcare, hospitality, and others.
Cellium’s EdgeAir is an end-to-end antenna-extension subsystem comprising a base unit (BU) that distributes the analog RF signal to various remote units (RUs) mounted within the indoor space. The analog RF signal is distributed via the BU to multiple RUs over existing in-wall copper cables such as CATx or coax. The BU consists of antenna ports that connect back to any third-party RAN or Wi-Fi signal source via a standard RF cable.
Based on Cellium’s intelligent system on a chip, the EdgeAir system optimally distributes any sub-7GHz wireless protocol to address the current and future needs of in-building wireless connectivity. It is compatible with all existing and future wireless technologies, including cellular 5G, Wi-Fi 6/6E, and IoT networks.
