LUCENT TECHNOLOGIES SOFTWARE IMPROVES CAPACITY AND COVERAGE OF WIRELESS NETS.Lucent Technologies (NYSE NYSE See: New York Stock Exchange :LU) has developed a software system that increases the capacity and coverage of wireless networks, which can dramatically reduce dropped or blocked calls. The OCELOT ocelot (äs`əlŏt', ō`sə–), medium-sized cat, Felis pardalis, of Central and South America. It is occasionally found as far N as Texas. The ocelot has a yellow-brown coat with black spots, rings, and stripes. software system, offered as part of Lucent-built networks, also allows service providers to install their networks more quickly and to continually optimize them as they evolve. Currently, deploying a wireless network is a painstaking process. Radio engineers with test gear drive around the intended coverage area, identifying spots where customers may have trouble making calls. Other engineers then make adjustments to base-station antennas for better coverage. However, because one adjustment can affect the performance of the entire network, engineers routinely take weeks to complete initial drive tests, and they continue the testing after a network enters service. "The OCELOT software virtually eliminates the need for drive tests because it allows service providers to deploy networks in their optimized state," said Paul Mankiewich, vice president of wireless advanced technologies for Lucent's Wireless Networks Group. "This will allow a quicker migration to the next generation of wireless networks, which will bring the mobile Internet Refers to gaining access to the Internet using a lightweight, handheld device.

The OCELOT software creates a mathematical model
A multidisciplinary team of Bell Labs scientists and engineers brought the OCELOT software from the labs to the field in less than a year. The software has been used in several U.S. and international markets for second-generation wireless networks, and it will support all digital cellular standards, including UMTS (Universal Mobile Telecommunications System) The GSM implementation of the 3G wireless phone system. Part of IMT-2000, UMTS provides service in the 2 GHz band and offers global roaming and personalized features. and 3G-1X (cdma2000), as well as IS-95 CDMA, GSM, and TDMA (Time Division Multiple Access) A satellite and cellular phone technology that interleaves multiple digital signals onto a single high-speed channel. For cellular, TDMA triples the capacity of the original analog method (FDMA). . Currently, some system settings recommended by the OCELOT software can be adjusted remotely, but antenna tilt and orientation have to be changed manually. Bell Labs engineers have developed self-adjusting antennas, which would -- when used with the OCELOT optimization tool enable wireless networks to reconfigure themselves in real time. Such a system could increase calling capacity along major highways during rush hour traffic or handle unforeseen changes in wireless network traffic patterns. Bell Labs is celebrating its 75th anniversary this year. One of the most innovative R&D entities in the world, Bell Labs has generated more than 27,000 patents since 1925. It has played a pivotal role in inventing or perfecting key communications technologies Noun 1. communications technology - the activity of designing and constructing and maintaining communication systems engineering, technology - the practical application of science to commerce or industry for most of the 20th century, including transistors, digital networking and signal processing See DSP. , lasers and fiber-optic communications systems, communications satellites, cellular telephony, electronic switching of calls, touch-tone dialing, and modems. Today, Bell Labs continues to draw some of the best scientific minds. With more than 27,000 employees located in 29 countries, it is the largest R&D organization in the world dedicated to communications and the world's leading source of new communications technologies.
