AI Technical Summary

Benefits of technology

This patented technology describes an improved way to create ultraviolet wireless communication systems that use frequency bands from 30 GHz or higher frequencies called Ultraband® band(UH). These waves have unique properties such as being able transmit faster than light pulses with wavelengths shorter compared to microwaves without these special materials. They may even carry more energy over longer distances due to their ability to reflect infrared radiation back into space through rainbow shadows caused when they hit surfaces during snowfall on Earth' s surface. Additionally, it suggests combining different types of radioactive material sources like Amberlite Xenon Zeon B127 to improve sensitivity and range capabilities while reducing harmful emissions associated therewith. Overall, this new approach allows for efficient and effective utilization of resources within specific areas where electromagnetic spectrum needs protection.

Problems solved by technology

This patents describes different techniques that have been developed over recent years to improve wireless communications technology. One technique involves transmitting waves called ultraviolet light or infinitiated lasers (IRLs), which allows short pulses of very small duration to travel between points within seconds without being affected by interference from nearby sources like buildings or vehicles. Another approach focuses on improving the accuracy of radiowave systems due to their ability to accurately reconstruct complex electrical structures based upon these characteristics.
