The Wiliot bridges serve three operational tasks: energizing Wiliot IoT Pixels, receiving and filtering packets from Pixels, and echoing the filtered packets to gateways. The Minew Dual Band Reference Bridge runs Wiliot firmware and is optimized for Wiliot deployments. It features a Sub-1 GHz antenna for energizing Pixels and a 2.4 GHz antenna for echoing Wiliot Bluetooth packets.
In addition to this bridge, Wiliot supports partners in selecting the best bridge for their application, or creating their own bridge and bridge firmware. Please contact a Wiliot representative to learn more.

Bridge and Tag Orientation
The relative orientation of the bridge and tag antenna will affect energizing and broadcasting performance. The Dual Linear antenna in the Minew Dual Band Bridge makes it agnostic to in-plane (zy) tag orientation, and more capable of out-of-plane tag (xz and xy) energizing.
Optimal pixel orientation shown in green, and suboptimal in red, relative to the energizing bridge antenna. In the drawing, the antenna's dual linear polarizations are aligned with the y axis and z axis.
