Ambient and Bechtel Start Up Powerline Telecommunications Testing.

Business Editors

NEW YORK--(BUSINESS WIRE)--Aug. 22, 2001

Initial Results Confirm Signal Transmission

Over US Government Lab Power Grid

Ambient Corp. (OTC ABTG: BB), the world leader in Powerline Telecommunications (PLT) technology, and Bechtel Telecommunications, a unit of Bechtel Corporation and a leading network engineering and construction firm, this week obtained results from initial large-scale testing and analysis of Ambient's proprietary PLT technology at the Idaho National Engineering and Environmental Laboratory (INEEL).

Preliminary results indicate that the PLT signal can be transmitted and received over distances greater than 0.5 miles. For most of the frequency band of interest, the loss of signal levels over these distances was not much greater than those for much shorter distances.

"These test results provide confirmation for our belief that the PLT signal can be propagated over longer distances," stated Ambient CEO Mark Isaacson.

Initial measurement and connectivity testing over INEEL medium and low voltage power lines began August 13. Test and measurement equipment from Ambient is being connected to circuits serving some of INEEL's 45 laboratories at the site.

The testing will use the INEEL facility's unique environment to simulate real-world market conditions. Tests will be conducted on overhead and underground power lines and will include transmitting data to users within the INEEL complex. Bechtel Telecoms president George Conniff noted: "Sending high frequency data transmissions over power lines to connections in end user premises is pace-setting technology that could not be tested on such a large scale anywhere but at INEEL."

Testing will be conducted in phases including Component Testing and System Simulation Testing. Individual components such as inductive couplers and shunt capacitors will be tested to verify operation on medium and low voltage lines. System Simulation Testing configurations will include those found in urban, suburban, rural, and undeveloped locations. Tests will also include radio frequency emissions and other certification tests.

Additional testing will ensure compliance with appropriate safety, environmental, and other standards and regulations by all components of Ambient's system. INEEL will also serve as a demonstration site to showcase Ambient's PLT technology to interested parties from the utility and financial investment community.

Ram Rao, Ambient Chief Network Architect, stated, "I have been out at INEEL and have been impressed with its world class facilities. INEEL offers Ambient an unparalleled opportunity to test and demonstrate its Powerline Telecommunications (PLT) technology."

Last June, Bechtel Telecoms and Ambient announced an agreement to research and test new products and technologies such as PLT at INEEL. Bechtel Telecoms is providing support in the market delivery of Ambient's PLT technology by providing general contracting related to system mapping surveys, demonstrations, lab testing, project management, crew support, and commercial implementation support. Bechtel will also assist Ambient with compliance with utility commission or utility board regulations and guidelines, and applicable state and federal laws, both in the United States and abroad.

Ambient Corporation has developed and owns innovative and proprietary technology that facilitates the transfer of Internet and high-speed data through ordinary electric powerlines. The same electric wiring that is ordinarily used to transmit electrical power to individual homes and businesses can also be used to transmit high-speed data. Ambient's Powerline Telecommunications (PLT) technology is designed to enable utilities and power companies to partner with Ambient in creating baskets of utility and consumer services.

These utility services may include features such as automatic meter reading (AMR), load switching/balancing, demand management, outage reporting, real-time billing, and alarm monitoring. Consumer services may feature Internet, telephony, video-on-demand, content delivery, and smart appliances. Both baskets of services will be achieved using Ambient's Powerline Telecommunications (PLT) technology across electrical powerlines and utilizing existing infrastructure.
