On Thu, 30 Dec 2010 19:15:19 -0800, "NSA TORTURE TECHNOLOGY, NEWS and RESEARCH" wrote: Existing directional antennas that transmit high-frequency radio waves require expensive materials or precise manufacturing WRONG - cheap lands on PCboard. This "beam-forming" capability makes the antennas crucial to ultrafast wireless applications, because they can focus a stream of high-frequency radio waves that would quickly dissipate using normal antennas. WRONG - no way it can track multi-path "Beam-forming antennas are the key for enabling next-generation, high-data-rate indoor wireless applications," says Anmol Sheth, at Intel Labs in Seattle. "Without beam-forming antennas it would be difficult to scale to the levels of density of wireless devices we expect to have in future homes." WRONG - try using another BAND, or encoding. There are two types of plasma antenna: semiconductor or solid-state antennas, such as PSiAN, and gas antennas. Both could fit the bill, but solid-state antennas are favoured as they are more compact and have no moving parts. SO WHAT ? All other antennas have NO MOVING PARTS. Compact = Lossy and ineffecient. That makes them attractive for use in a new generation of ultrafast Wi-Fi, known as Wi-Gig. Existing Wi-Fi tops out at 54 megabits of data per second, whereas the Wi-Gig standard is expected to go up to between 1 and 7 gigabits per second - fast enough to download a television programme in seconds. WRONG - how far can you transmit ? a few INCHES ??? Wi-Gig requires higher radio wave frequencies, though: 60 gigahertz rather than the 2.4 GHz used by Wi-Fi. Signals at these frequencies disperse rapidly unless they are tightly focused, which is where PSiAN comes in. Too Lossy. Only reason 60 GHz is FCC has an open band there. Ian Russell, business development director at Plasma Antennas, says that PSiAN is small enough to fit inside a cellphone. "Higher frequencies mean shorter wavelengths and hence smaller antennas," he says. "The antenna actually becomes cheaper at the smaller scales because you need less silicon." SO WHAT ? It cant transmit more than a centimeter, SI TOO LOSSY -20 db antenna gain The antennas shouldn't raise any health issues, as they are covered by existing safety standards. WRONG - you have that BASS ACKWARDS The narrow beam means there is less "overspill" of radiation than with existing omnidirectional antennas. WRONG ! - How is "overspill" on an omni bad ???? "Semiconductor plasma antennas will work at only high frequencies, between 1 GHz and 100 GHz," says Anderson. "Theoretically, we see no upper or lower bound to ionised gas antennas in the radio frequency spectrum." WRONG - [also 100GHz you says is upper limit] Russell says that PSiAN could be commercially available within two years. At present, getting movies and high-quality images on and off our smartphones almost certainly means hooking them into a computer. But as the demand for such content increases, the only way to break the wire is going to be an ultrafast wireless connection. When it comes, it may very well be in the form of plasma. WRONG - Plasma takes time to establish, UNLIKE Todays proven cheap reliable EXISTING antenna technology(s) Well that just sucks! I was relying on plasma technology to accurately resolve LBW appeals.
