Abstract
A system for a redundant star network is disclosed. The system consists of a control hub, one or more backup hubs, and at least one peripheral device (PD), the peripheral device comprising a housing having at least one selectable side transparent or opaque to radio frequency (RF) transmissions while the remaining sides are opaque to RF transmissions. The control hub controls the PD, for example by controlling how the PD operates under certain conditions. The PD includes a long-range, wireless transceiver and a microcontroller, which includes instructions for periodically testing, via test signals, whether the control hub is functional. In the case that the control hub does not respond to the test signals, the PD includes instructions for switching control of the PD to the backup hub, which also stores control instructions for the PD, similar to the control hub.
