DailyDirt: Is There A Better Word For Wireless?
from the urls-we-dig-up dept
- If you're really paranoid about someone intercepting your home WiFi network, maybe someday you can set up a wireless network that transmits via visible wavelengths (so a wall would effectively block out would-be eavesdroppers). It might be annoying to set up a wireless network like this for more than one room, though. [url]
- Cheap, high-bandwidth transmitters for satellite communications in the 42-25 GHz range might be nice to have in a smartphone. A couple DARPA teams have demonstrated the feasibility of millimeter-wave power amplifiers on silicon chips for the first time. [url]
- T-rays (aka terahertz rays) have been shown to break the 3 Gbps barrier -- but a T-ray based WiFi network would probably only achieve 100 Gbps and have a range of about 10 meters. FYI: T-rays are part of the unregulated spectrum, and they can penetrate some materials (but not metals or water). [url]
