The ProtoAir wireless gateway is an external, high-performance, low-cost building automation and industrial control IIoT gateway for original equipment manufacturers (OEMs) that provides manufacturers connectivity into the cloud and instant multi-protocol deployment of field protocols, enabling new or legacy devices to easily interface with other protocols.

Enjoy the benefits of the cloud connectivity through FieldPoP™. The ProtoAir is FieldPoP-enabled, meaning all ProtoAirs can be registered to FieldPoP, Sierra Monitor’s device cloud for the IIoT. The FieldPoP web interface lets users remotely access, in a secure fashion, the FS-GUI and custom web applications that are available locally on the ProtoAir. These applications offer functionality for configuration, monitoring, logging, security, diagnostics, and updates.

The ProtoAir wireless gateway provides OEMs with the ability to perform standard protocol translation between devices over a wireless network when wired networks are not available or difficult to access using connectivity options such as Wi-Fi, Bluetooth, and cellular. This will enable access between devices or networks of devices to management systems or to the cloud over the air for remote device management, control, and diagnostics.

As the first wireless product in its well-regarded FieldServer IIoT gateway and router family, the ProtoAir offers all the benefits of the FieldServer family, such as flexibility with the world’s largest library of 140+ protocols as well as low installation and operating costs. The ProtoAir has the ability to connect to any one or more of the FieldServer standard drivers via the serial or Ethernet port, enabling many different devices and or networks wirelessly.

With the ability to connect devices to the cloud over wireless and cellular connections and automatically support multiple known controller profiles, the ProtoAir is the instant answer to a manufacturer's needs to meet IIoT and customer needs.
