Physical barriers may block or weaken a wireless signal and should be considered when placing your COBRA equipment. The best advice for alleviating this potential concern is to have direct line-of-sight (LOS) between your COBRA Controller and Module after placement.
COBRA's utilization of MESH-signal technology (Firmware 5.0 and higher) significantly mitigates much of the concern surrounding LOS. MESH networks are designed for non-line-of-sight configurations, with each module improving signal within your COBRA Network. LOS is less critical with MESH as COBRA Modules and Audio Box act as wireless repeaters and transmit the data directly between each other without needing a direct visual line to the Controller.
If your signal is not as strong as desired, consider what items may be causing a disruption and re-position devices, keeping in mind nature's natural barriers such as trees, leaves, and boulders which can cause similar interference as buildings and other man-made structures. According to the U.S National Institute of Standards and Technology, certain materials can interfere with wireless transmissions more than others (listed in order of signal loss potential, drywall and plywood coming close to zero):
- Masonry block
