Sure-Fi Radio Technology Supersedes Bluetooth and Wi-Fi in Extremely Harsh Environments

Sure-Fi has developed the world’s first radio whose signals can “leap” through tall buildings of metal, brick, concrete and anything else preventing typical signals from getting through. This patented technology can be installed in minutes and is being used at construction sites, mining facilities, factories and congested areas like apartment complexes and stadiums.

Wi-Fi and Bluetooth signals can only go about 300 feet and are often slowed down, interrupted or blocked in congested areas. Worse yet, trends in technology are pushing developers to higher bandwidths and frequencies, which have less ability to penetrate obstructions.

Sure-Fi signals can travel one mile through obstructions or more than 50 miles line-of-sight by using patented radio technology based on Chirp Modulation. Chirp is a component of a radio signal where the actual signal increases and decreases in frequency, creating a pulse or chirp. These chirps contain the transmitted data.

This method helps the signal to be easily distinguished from noise, which can be critical in extremely noisy environments. The Sure-Fi signal is more robust than Bluetooth or other commonly used technologies. This technology also makes the signal practically impossible to intercept. By incorporating a military-grade cryptographic algorithm along with other proprietary obscuring techniques, the Sure-Fi radio is more secure than the wire it replaces.

The video below shows how the Sure-Fi signal can penetrate a Faraday cage that’s one floor and 100 yards away. The Faraday cage is made of conductive material designed to prevent radio signals and any other form of electromagnetic interference from affecting sensitive electronics. 


Different Sure-Fi systems are available to replace wires for access and industrial controls as well as HVAC and relay systems. For more information about Sure-Fi systems, click here.
