Researchers and industry professionals must first resolve some technological barriers before Wireless Information Integration can become a reality.
1. Unmanned GAN Platform
Self-supporting, autonomous blimps hovering at 20 km will blanket GAN signals over 800,000 sq km. Current unmanned aircraft stay aloft for 48 hours, and cell phone towers cover only 26 sq km.
The GAN will require 500 Gbps fiber optic landlines encrypted with quantum cryptography to connect GAN communication hub stations, buildings broadcasting unidirectional signals to blimps. Modern fiber optics operates at only a few gigabits per second.
2. Compact, High-Throughput Transponder
FDIAs need nanomechanical antennae capable of 8 Gbps, 5 GHz transmissions. Cell phone antennae are 3-9 cm long and handle 144 Kbps, 900 MHz transmissions. The best existing nanoantenna (engineered at Boston University) oscillates at 1.49 GHz.
3. Advances in Nano-Lithography
According to Moore’s law, the FDIA will run at several hundred gigahertz. In order to engineer advanced circuitry and MRAM chips, companies will use nanosphere lithography, which requires a 5-nm process. Companies currently use a 45-nm process. Existing MRAM chips store only 16 bits of data; the FDIA needs 8-terabyte MRAM chips.
4. Compact, Flexible Power SourceOrganic radical batteries (ORB) will be thin, flexible, and biodegradable. Unlike modern batteries, ORBs use organic radicals, not toxic compounds. Existing ORBs recharge in 30 seconds; the FDIA's ORB will recharge in two.
