This will require advances in software and smart user interface technologies, including virtual reality and interface agents. A major technical challenge that must be met to make WICS a reality is the improvement in communications technologies for voice, images, video, and data. Improved bit rates, data compression, and higher bandwidths are essential to this effort. Developments in laser communications are needed. One attractive alternative is the use of lasers to pass information.
Lasers are attractive because of their higher data rates and smaller beam divergence angles.
Also, methods are needed to mitigate the signal-degrading effects of atmospheric turbulence. In addition to improved pointing and tracking capabilities, several other steps must be taken to protect friendly access and deny unfriendly access to the system. Secure communications capabilities will be essential due to the sensitive nature of the information. Standard cryptographic and jamming techniques must be improved. Communications and access redundancy will be essential.
