Golden Bridge Technology Featured On Caspar Weinberger's World Business Review TV Series
BOCA RATON, Fla.--(BUSINESS WIRE)--Feb. 12, 1999--Multi-Media Productions (USA), Inc. announces the appearance of Feliciano Giordano, founding president of Golden Bridge Technology, Inc. and managing director of GBT Europe, on World Business Review.
The weekly television series focuses on technology and is hosted by Caspar Weinberger, Chairman of Forbes magazine and Secretary of Defense during the Reagan administration. Also appearing on the show is communications industry expert Sue Almeida, co-founder of Network Strategy Partners LLC, to discuss the topic of Remote Access Services.
''Golden Bridge Technology was selected to appear on the show because its application of former military technology may revolutionize the wireless communications industry,'' said Charles Hopkins, the show's Associate Producer.
Golden Bridge Technology, Inc. (GBT) is developing commercial applications for a former military technology called Spread Spectrum, and is providing a number of wireless communication devices for the mobile telephone and Internet markets.
''The technology enables assured communications, highest quality of service and privacy in a highly congested electromagnetic environment,'' said Giordano. This is accomplished by spreading the signal to be transmitted over a wide frequency band (thus the name spread spectrum) using a pseudo-random code, so it appears as noise or static. It then mixes with background noise, making the signal nearly undetectable.
At the receive end, the signal is 'de-spread' using the same code, resulting in the exact recovery of the original signal. ''This gives the user wired line quality in a mobile telephone service,'' said Giordano. A different code is used for every communication session, which provides almost absolute privacy.
Other applications include wireless local loop, mobile telephony, Local Area Networks, and high data rate direct connection to the Internet. Almeida said GBT's use of Spread Spectrum was indicative of a growing trend she called 'anywhere access.' ''This is a huge trend,'' she said. ''What we're doing as an industry is trying to give everyone access to all of their tools all of the time.''
The most difficult task in Spread Spectrum is the design of the receiver module used to capture and de-spread the signal. ''This is known as signal acquisition,'' said Giordano, who added, ''Conventional methods for signal acquisition are relatively slow, creating a number of system design limitations that affect quality of service, capacity and complexity.
A very fast signal acquisition method, using a device called a Matched Filter, was invented over forty years ago at MIT, said Giordano. The filter essentially enabled the instantaneous capture and analysis of the signal, however due to its size and the circuitry required to manufacture the device, it was not practical for commercial use. Another drawback to commercialization of the filter was the fact that it produced a very high power drain, thus a very short battery life.
A number of inventions by GBT scientists have drastically reduced both the size of the circuit and its power drain, making it more suitable for commercial applications. ''Advances in semiconductor technology have contributed to the reduction in the size and cost of the chip on which the circuit is located,'' Giordano stated. This has enabled GBT to develop a Matched Filter based technology that has opened whole new vistas in wireless communications for all sorts of applications and markets, such as cordless telephones.
One of the areas GBT has focused on is applying spread spectrum technology to the next generation cellular system. In January, 1998 the world's standards bodies universally adopted a particular implementation of Spread Spectrum, known as W-CDMA ('W' stands for 'wideband), for Third Generation Cellular systems (G3), because of the greater capacity the application enables. By design, this is the exact technology GBT had decided to develop when the company was formed in 1995. ''The other choice would have been Narrowband-CDMA, which exhibits inferior performance characteristics in addition to lower capacity,'' said Giordano. As a result, GBT's Matched Filter based technology has been adopted in the US WP-CDMA proposal to the International Telecommunications Union for the IMT2000, the global standard for the next generation cellular system.
