Since then, we have provided BLE solutions to over 30,000 end-users, delivered via +1,100 partners using +3 million IoT devices in the field. Today our solutions cover approximately one billion sq ft. We continue to be a pioneer in the field, with a focus on Smart Buildings in Healthcare and Corporate Real Estate Spaces.
