Lucent Technologies signs US$30 million contract with Portugal's largest GSM operator CANNES, FRANCE - Lucent Technologies announced a US$30 million contract with Telecel, Portugal's most successful mobile telecommunications operator, to provide wireless systems and installation services for Telecel's Global Systems for Mobile Communications (GSM) network. The contract was signed today by Jim Brewington, President of Lucent Technologies' Network Wireless Group, and Antonio Carrapatoso, CEO of Telecel, at a signing ceremony held at the GSM World Congress in Cannes, France. Under the terms of the contract, Lucent will supply its GSM 900 and 1800 Base Station Systems (BSS-2000). Lucent expects to start deployment of the BSS-2000 system in the eastern part of Lisbon and Evora by June 1998, to coincide with the opening of the World Expo Com'98, when millions of visitors are expected to require seamless mobile voice and data services. The second phase of installation will cover other major cities in the north and centre of Portugal. "We are delighted to be working with Telecel on this project," said Brewington. "This agreement has reinforced Lucent's reputation as a major supplier of turnkey GSM solutions throughout Europe." Lucent's BSS-2000 includes the Compact BTS-2000/2C base transceiver station with 2x5W output, and the BCF-2000 base station controller, both of which were launched at the GSM World Congress in 1997. The Compact BTS-2000/2C provides the radio interface to mobile stations in the GSM 900 and 1800 bands. The small size and low weight of this device means it can be mounted in a variety of indoor or outdoor configurations. The BCF-2000 has a modular architecture which allows operators to start with a low-capacity base station controller, and then grow the system as the number of subscribers increases, thereby minimising initial infrastructure costs. "Lucent's quality and experience in the global wireless market made it an obvious choice to be our second supplier," said Wayne Ross, Vice President of Engineering and Operations of Telecel. "Telecel prides itself on providing its customers with the best GSM network and services available, and by working with Lucent to enhance our infrastructure we can be sure we will continue to meet this high standard." Lucent has won major contracts to supply GSM infrastructure equipment to service providers around the world. Its growing list of customers includes KG Telecom and Tuntex Telecom of Taiwan, T-Mobil of Germany, Pacific Link of Hong Kong, Escotel of India and Celcom of Malaysia. Lucent has also successfully completed the first GSM 1800 network trial in the Philippines. Lucent has significant experience in rapid deployment of end-to-end wireless solutions. Its networks support a variety of subscribers and applications, and range in size from several thousand subscribers to over a million. Lucent Technologies is a co-founder of the Universal Mobile Telecommunications Systems (UMTS) Forum and is also actively involved in the development of other third-generation wireless technologies. Telecel, which has a majority ownership by US-based wireless service provider AirTouch, is the most successful GSM operator in Portugal. Regards, Serry Habash

Lucent Technologies' Bell Labs scientists use micro-mirrors and free-space optics to route and switch lightwave signals MURRAY HILL, N.J. - Scientists at Bell Labs, the research and development arm of Lucent Technologies, have demonstrated an experimental device that combines free-space optics and microscopic mirrors to route and switch individual wavelengths, or colors, of light transmitted simultaneously on an optical fiber. The micro-mirrors -- so small that about 100 of them would fit on the head of a pin -- are used to add or drop specific wavelengths, switching them in and out of the transmission fiber, without disturbing the remaining channels. In an optical communication system, each wavelength serves as a channel that carries information encoded in the ones and zeros of digital data. High-capacity systems use wavelength-division multiplexing (WDM) technology, to transmit multiple wavelengths at once. In the Bell Labs experiment, an optical-imaging system substitutes for a conventional wavelength-router assembly and an array of micro-mirrors replaces individual switches. In a commercial application, this technology could reduce cost, require less space, and increase efficiency. A patent covering the device has been filed with the U.S. Patent Office. The Bell Labs research team includes Joseph Ford, James Walker, Vladimir Aksyuk and David Bishop. The mirrors are micro-electro mechanical systems (MEMS) devices, used in an innovative way. "This is a substantial achievement," said Cherry Murray, director of the Bell Labs Physical Research Lab. "With this MEMS technology, one can integrate optical switching into a WDM system, allowing for needed components like wavelength-channel add-drops and cross-connects based on standard silicon technology and free-space or integrated waveguide optics." The system uses a WDM switch in which multi-wavelength light from an optical fiber is imaged through a diffraction grating onto a column of micro-mechanical tilt-mirrors. The mirrors are positioned so that each is illuminated by a single wavelength, and they are tilted so that individual wavelength signals are either passed into the output fiber or reflected directly back into the input fiber. The switch becomes a four-port add/drop when placed between two optical circulators, in which data traffic is handled in a manner similar to the way vehicles are routed through a traffic circle at a city intersection. Each input wavelength signal passes through the first circulator and enters the WDM switch, in which the active switching device is a column of 16 micro-electro-mechanical tilt-mirrors. Depending on the mirror angle, the light is either reflected back into the original input port or tilted by about 20 degrees and carried into a second output port. Signals to be passed along without modification are reflected by the switch and are returned to exit through the circulator. Signals to be dropped are transmitted through the switch and pass through a second circulator to the drop output. If the switch is set to drop a wavelength channel, the reverse path is open to accept an "add" signal, which enters through the second circulator. The WDM add and drop channels can be separated or combined onto individual fibers, using external wavelength routers. The mirrors, much too small to be made by conventional machine technology, were designed at Bell Labs and fabricated by MCNC, a MEMS foundry in Research Triangle Park, North Carolina, using the Multi-User MEMS Processes (MUMPs). MCNC is supported by the Defense Advanced Research Projects Agency (DARPA). "MEMS is an exciting technology being investigated by Bell Labs researchers," said Ron Genova, business development manager for Lucent's Microelectronics Group. "The Microelectronics Group is a leading supplier of a complete portfolio of optoelectronic components for optical networking. It's also our job to evaluate new technologies from Bell Labs, such as MEMS, and decide how to eventually market that technology in the form of innovative products." Bell Labs is a global leader in optical technology with more than 1,600 patents in the field. A Bell Labs breakthrough in ultra-dense wavelength division multiplexing led to the recently announced WaveStar OLS 400G, an optical networking system that achieves the record-breaking capacity of 400 gigabits (billion bits) per second over a single fiber.
