“I Can Hear You Now” With Sure-Fi, a Radio Signal That Blows Away Bluetooth and Wi-Fi

9 Jul 2019

PROVO, Utah--(BUSINESS WIRE)--Sure-Fi has developed the world’s first radio with Superman-like qualities to “leap” signals 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 in construction, mining, factories and congested areas like apartment complexes and stadiums.

“Most wireless communications have poor range and reliability because they try to use the highest data rates possible,” said Mark Hall, Sure-Fi Founder and CEO. “At Sure-Fi we’ve gone the other direction. By focusing on lower data rates, and developing a new radio module from the ground up, we’ve been able to create something other RF technologies are unable to provide, a signal that is sure as a wire.”

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 ever higher bandwidths and radio frequencies, which have less ability to penetrate obstructions. These signals sometimes have little or no security and can be vulnerable to attacks.

The Chirping Difference

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 be easily distinguished from noise, which can be critical in extremely noisy environments. The Sure-Fi signal is thousands of times 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.

Check out this video here to see 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. You can see the videos showing how Sure-Fi is being used to replace wiring in apartment complexes, businesses and automatic gates at the @SureFiInc Twitter page.

About Sure-Fi

Sure-Fi has been developing RF technology since 2015 focusing on “Bunker Busting,” low-data rate communications through seemingly impenetrable obstacles and over long distances. Founder and CEO Mark Hall was inspired to develop Sure-Fi after learning homeowners often couldn’t get a Wi-Fi or Bluetooth signal outside of a garage so they can use a “Smart” keypad to control their garage doors. This technology has proven to be invaluable to numerous businesses and industries. The company is located in Provo, Utah, within the Provo Opportunity Zone, identified as one of the nation’s top three “opportunity zone” clusters and gaining a reputation as the next Silicon Valley.
