Ambient Issues Stockholder Update
Thursday November 15, 8:30 am ET

BOSTON--(BUSINESS WIRE)--Ambient Corporation (OTCBB: ABTG - News), a leader in Broadband over Power Lines (BPL) solutions, issued today the following update to its stockholders from President and CEO John J. Joyce.

Dear Stockholders:

Since my last update to shareholders on September 26, 2007, I am pleased to report Ambient has continued to make progress with our largest field deployment in the southeastern United States. Our deployments with Consolidated Edison, FirstEnergy Service Company and Entergy Corporation also continue to operate. These deployments, which use Ambient’s suite of BPL products, are directed towards a variety of goals including striving to dramatically improve the efficiency with which utilities serve their customers.

The Company’s focus remains on enabling Smart Grid applications. We remain active with outreach and developing relationships with key industry players. Recently, Ambient joined over 50 other green companies at the Massachusetts Technology Transfer Center's 3rd Annual Conference on Clean Energy to represent Smart Grid communications, and was present at the New York meeting of ValueRich, connecting Ambient with clean energy institutional investors.

Ambient also received its fourth U.S. patent in 2007, bringing the Company’s patent portfolio to eighteen (18) U.S. patents, covering a number of BPL technology areas. Ambient’s patents encompass such areas as data couplers on medium voltage power lines, coupler enhancements, data coupler usage, coupler placement in buildings, coupler construction and solutions to overcoming challenges of high voltage stress and high current. Actual patents and their claims may be viewed at www.uspto.gov. The US Patent and Trademark Office has notified Ambient of additional applications whose claims have been allowed, and publication is anticipated to follow.

Key Ambient personnel continue to participate in the development process of industry standards and legislation in both the U.S. House of Representatives (HR 3221) and the U.S. Senate (HR 6) through the GridWise Alliance and other lobbying efforts. As Ambient has previously stated, the Company believes the establishment of standards will help drive industry adoption for Smart Grids worldwide. Ambient’s system architecture is designed to incorporate any standards-based products, including any chipset, and can be modified to accommodate any standards-based chipset. Ambient equipment can be available as quickly as compliant chipsets are available.

In addition to the most recent financing of an additional $2.5MM of capital announced on November 2, 2007, the Company has notified the 2006 Debenture holders that it intends to pay the scheduled December 2007 payment in cash, rather than in registered shares of Ambient stock. As part of its continuing efforts to limit the distribution of Ambient stock at a discount-to-market price, Ambient has paid in cash the last five scheduled monthly 2006 Debenture payments, reducing current debt. Ambient’s remaining short-term debt with the 2006 Debenture holders, after making the December payment in cash, will be $103,500.

With the aforementioned developments, Ambient continues to strive to meet the following goals and objectives set forth in the 2007 Annual Meeting: increasing revenues, enhancing the Company’s technology and protecting its intellectual property rights, fostering the creation of industry standards and stabilizing the capital structure.

Unaudited consolidated financial statements for the nine months ended September 30, 2007, can be found in our third quarter 10QSB filed with the SEC on November 14, 2007 at http://www.sec.gov.

As always, thank you for your continued support and interest in Ambient.

Sincerely,

John J. Joyce

President and CEO of Ambient
