Developed ray-propagation and cell-planning tools for T-Mobile.
Electromagnetic Interference Issues
Developed analytical models and propose cost effective solutions for electromagnetic interference and electromagnetic compatability (EMI/EMC) and ISR (intelligence, surveillance and reconnaissance) sensors for expanded US Navy E2-C Advanced Hawkeye and EA-6B Prowler missions for Northrop Grumman.
Smart Antennas
Developed ranging and localization techniques and propose smart antenna structures for WLAN and RFID for Symbol Technology.
Multipath Propagation
Developed space-time-frequency technique to mitigate time-varying multipath propagation effects and HFT transmissions and cellular communications for Fujitsu.
Image Communication
CATT has been deeply involved in addressing technological challenges in the area of image communication,
including the issues raised by the introduction of digital video for applications such as high definition
television and videoconferencing, as well as issues related to financial document imaging and magnetic
resonance medical imaging.
Image Compression
In conjunction with AT&T Bell Laboratories, CATT has developed new methods for motion estimation,
a key component in the compression of video sequences. CATT has also developed techniques for image
coding and reconstruction that will permit images to be transmitted over packet networks and minimize
the degradation caused by the inevitable loss of packets during transmission. Working with doctors
at Cornell University Medical College, CATT has developed new techniques for compression of images
from magnetic resonance imaging.
In a project funded by AFP Imaging Corporation, CATT has developed novel wavelet-based algorithms
for the reduction of signal-dependent noise in digital dental x-ray images. The new software has
been incorporated in AFP's new generation of filmless digital dental x-ray imaging devices.
ATM
Through collaboration with Bellcore, the research organization funded by NYNEX and other
regional Bell Operating Companies, CATT devised methods for traffic management on ATM networks.
The demonstration of the feasibility of sophisticated traffic management schemes associated with
CATT research has had a significant impact on the development of ATM standards.
Broadband ISDN
Through its work with Bellcore, CATT developed connection establishment procedures for multimedia,
multiparty data transfer applicable to Broadband Integrated Services Digital Network (ISDN) signaling
systems.
Document Imaging
In a project funded by KeySpan Corporation (formerly Brooklyn Union), CATT has developed novel
techniques for the analysis and lossy compression of KeySpan's engineering drawings. This helped the modernization of the KeySpan Engineering Mapping System, and contributed to the
decline in KeySpan's gas and electricity distribution rates by approximately 20% over the past
five years. In another project funded by the FSTC (Financial Services Technology Consortium),
CATT has worked with banks and other financial institutions to study the feasibility of using
imaging techniques in the inter-bank check clearing process.
Traffic Planning and Capacity Engineering
Working with the research and development division of NYNEX Science and Technology, CATT developed
a prototype, the Data Network Management and Optimization Tool (DATANMOT) which can be used by NYNEX
for its traffic planning. The prototype includes a generic model for the simulation and analysis of
different network services and architectures. It can be used for traffic planning for frame relay
and asynchronous transfer mode (ATM) based services.
Wireless Signal Propagation
Models for wireless signal propagation developed at the CATT, with support from Motorola, Inc. and
Symbol Technologies, Inc., are being used in the latest computer programs for the layout of U.S. and
European cellular phone systems.
In Cooperation with Distinct Management Consultants of Columbia, MD., and Telenet Communications
(now Sprint International), CATT developed the Network Evaluation and Design System (NEDS), a
state-of-the-art packet-switched network design tool. This is an interactive PC tool, which was used to design and optimize a packet-switched network and was also used for developing
proposals and designing private networks for clients.
Network Design Software
A software package, MENTOR for the design of broadband networks, was developed at CATT and was used by IBM for its internal network design and consulting services.
Network Bridging
Because LANs are now so ubiquitous, the ability to bridge them is critical. CATT has conducted
extensive research on LAN bridges in cooperation with the Securities Industry Automation Corp.
(SIAC), the technology operations center for the New York and American Stock Exchanges. This
research enabled SIAC to validate the technically challenging design of the trading floor
networks for the exchanges.
Real Time Systems
For NASDAQ, CATT performed validation and verification on the first nationwide, real time, financial
trading system.
UNIX Network Design Workbench
CATT developed a prototype of a UNIX-based Network Design Workbench. This prototype includes a number
of fundamental network design algorithms. As part of this project, CATT created a graphical user
interface (GUI) for accessing these algorithms using the X-window interface and Motif.
Advanced Network Management
For IBM the DCC developed NETMATE, a comprehensive system for the management of complex networks.
NETMATE is being used in numerous commercial and development organizations to manage networks and
develop network components such as bridges, routers and gateways. The NETMATE project was
competitively selected by IBM as one of five projects nationwide to be funded under its Complex
Systems Research Initiative.
