Introduction
The CloudLeaf Gateway is the access point for all Bluetooth based sensors tags, to
communicate with the Cloudleaf cloud. The Gateway co-locates with existing indoor wireless
networks via WiFi, USB, or Ethernet, ensuring quick & easy deployment. This also allows
existing wireless network security to be leveraged, extending end-to-end security with SSL/TLS
tunneling from the access point to the Cloudleaf’s Cloud.
The Gateway utilizes a proven wireless technology standard (Bluetooth 4.1) to communicate
with the downstream sensors, tags. It has two independent BLE radio subsystems, which create
scalability, link redundancy, and spectral diversity. It can perform scans on all three BLE
specifications-defined advertisement channels (37, 38, 39), ensuring all BLE devices present in
its 150 feet coverage range are visible. The access point is designed to provide visibility of
thousands of end-node devices, breaking the intrinsic limitation of BLE with the CloudSense
device management algorithm. For downstream device security, the access point supports
native 128-bit AES encryptions for all communications to the end-nodes.
The Gateway is designed to operate in harsh industrial environments, with the ability to
withstand extended operating temperature range from 0 C to 60 C. The access point can be
wall- or ceiling-mounted.
