The new antenna may have a favorable impact on the use of wireless networks in corporate settings or for business transactions. Compared with radio frequencies, which pass right through walls, infrared beams can be more tightly controlled. "You make the network more secure because infrared energy is contained within a room and doesn't leak out through the walls and windows. You can equip the windows to reflect infrared energy," said Green. "Also, you can create a tight beam between one point and another which doesn?t diverge much in comparison to a radio frequency beam.".

Green also noted that the optical technology provides greater bandwidth for businesses and can transfer data over distances of up to three miles, Because the beams can be tightly controlled, Green said, it gives companies the ability to create several wireless networks within one room, "You can have private and public zones of activity within the same room or wide area," Green said, The antenna has been licensed to Optical Antenna Solutions, a company based strongfit designers case for apple iphone x and xs - pretty little elephant in Nottingham, England, The company plans to develop several commercial uses and will unveil the system at the Comdex trade show in Las Vegas next week..

One of the first ideas under development is for credit card payment systems. The idea is to equip credit cards with infrared links for use at gas pumps and supermarkets, for instance. An optical antenna that uses a geometrically shaped lens promises to bring greater security to wireless networks, according to British scientists. The new device, developed by researchers at the University of Warwick's engineering department, uses a combination of precise curvatures on the lens and a multilayered filter to achieve its goal.

Optical antennas are already available, But this new antenna is so precise, according to the researchers, that it can detect a signal on a single wavelength of light, The scientists, led by professor Roger Green, assert strongfit designers case for apple iphone x and xs - pretty little elephant that the device is 100 times more efficient at gathering in a signal than any previous optical sensor of this kind, Be respectful, keep it civil and stay on topic, We delete comments that violate our policy, which we encourage you to read, Discussion threads can be closed at any time at our discretion..

CNET también está disponible en español. Don't show this again. The trial is designed to demonstrate the benefits of the hybrid network gear to wireless carriers. "What we want to do is say 'Hey, there are other ways of reaching (your) plans,'" Jha said. The GSM and 1x phone standards are usually incompatible. GSM carriers building new wireless networks are usually limited to equipment using the GPRS (General Packet Radio Service) or EDGE (Enhanced Data Rates for GSM Evolution) standards. So far, most of the United States' top six wireless carriers have been building so-called third-generation, or 3G, wireless networks, in hopes that its faster download speeds will generate extra revenue through wireless Web subscriptions, game downloads or corporate e-mail capabilities. Wireless carriers are trying to find new sources of revenue as the price of a cell phone call continues to drop because of competition.
