Plasma Antennas, a UK based company, believes that they have solved the slow speeds of wireless internet with the help of The Plasma Silicon Antenna (PSiAN). These plasma antennas would allow mobile devices, such as smart phones and tablets, to achieve high-data-rate transfers.
The PSiAN consists of thousands of diodes on a silicon chip. When charged the chip produces a small cloud of electrons that reflect high-frequency waves. The waves create a beam that can be focused by selectively activating particular diodes. Because the plasma antennas are capable of transmitting focused radio waves, unlike conventional antennas, they can transmit high data loads. This would allow for uninterrupted wireless streaming of videos and television on Wi-Fi enabled devices.
This is the same technology that is being used to develop directed energy weapons and radar arrays. The radar arrays could help cars navigate in low-visibility conditions.
The only down side to the PSiAN is its inability to beam through walls. The beam would have to be reflected throughout the building for indoor use. Plasma Antennas believes these antennas could be available within the next two years.
