                         EXPERIMENTAL LICENSE

       Ambient Corporation ("Company") submits this six-month progress report in accordance
with the conditions of its Experimental License to evaluate broadband access via carrier current
systems over power lines.

                                          *      *      *

Test Sites: The Company has continued its ongoing test program at its test site in Westchester
County, New York, since the grant of its original STA in June 2002. The physical layout of this
system was unchanged during the last six month reporting period, and as previously reported,
now consists of second generation equipment. Radiated emission measurements data taken at
locations where new second generation equipment was installed was provided in the Company's
Progress Report submitted August 1, 2007, and is re-attached here.

The Company continues the BPL Trial with FirstEnergy Corporation in Brimfield, Ohio.
Currently, this system consists of 24 second generation nodes on two medium voltage circuits.

The Company's BPL Trial with Entergy Corporation is performed near Little Rock, Arkansas.
This Access BPL test system includes nine second generation nodes on the single medium
voltage circuit.

Since February, 2005, the Company has operated an in-building Low Voltage demonstration
system at a 200 unit high-rise apartment building in New York, NY, to test and demonstrate
broadband internet access capabilities. During the last six months the Company has significantly
reduced the scale of this trial, and anticipates that it will conclude this experiment by the end of
June, 2009.

BPL Standards Development: During the last six months, members of the Company's
engineering staff participated in the following IEEE meetings:

Dr. Yehuda Cern, Vice Chair and Technical Editor of IEEE Working Group P1675, reports that
the "Standard for Broadband over Power Line Hardware and Personnel Safety" has been
officially approved and published.

Aron Viner, Ambient Director of Compliance & Standardization, is Chair of the PLC EMC
Standard Working Group which will develop the Standard "Powerline Communication
Equipment. Electromagnetic Compatibility (EMC) Requirements. Testing and Measurement


Methods." The Draft has been completed and approved by IEEE Power & Energy
Communications and EMC Societies, for balloting. The Draft will move to the balloting phase in
the first quarter of 2009

Ram Rao, the Company’s Chief Network Architect, and Aron Viner, members of IEEE P1901,
the BPL MAC/ PHY Standard Working Group, are participating in the development of a
"Standard for Broadband over Power Line Networks: Medium Access Control and Physical
Layer Specifications." The Standard is in early stage of development; however, the Working
Group made substantial commitments to ensure that EMC issues will be addressed in technical
requirements for Coexistence, Access and In-Home Clusters of the Standard. The Working
Group has made substantial progress in terms of choosing technical proposals for standards. As
of this report, the Working Group has approved the Access, In-Home, and Coexistence clusters
and is about to begin the actual writing of the first Draft

Testing of Advanced Hardware and Software Capabilities: In the framework of its Experimental
License, the Company continues to develop and test methods for enhancing the performance of
its BPL systems and to monitor and adjust the parameters of its test facilities to be responsive to
the concerns of the amateur radio operators consistent with its obligations under its Experimental
License. The Company's extensive experimental testing program made possible rapid
development of a new generation of the industry's first high-speed BPL access products and has
demonstrated the Company's technical leadership in the industry.

The Company continues to collect data for design verification of the power quality and
consumption parameters of its second generation equipment (12 units) operating on MV circuitry
in Briarcliff Manor. This data is being correlated and verified with data collected by the Utility
to provide a statistical basis with which to verify equipment power consumption in different
weather, temperature and data capacity conditions.

As previously reported to the Commission, the Company has notched out its signals on Amateur
bands, demonstrating significant advancements in our technology over the relatively short time
period of its test program. These bands include the following Amateur Radio bands: 80, 40, 30,
20, 17, 15, 12 and 10 meters: 3.5-4 MHz, 7-7.3 MHz, 10.1-10.15 MHz, 14.0-14.35 MHz, 18,068
-18,168 MHz, 21-21.45 MHz; 24,890-24,990 MHz, and 28.0-29.7 MHz. Also, the Ambient
frequency plan was modified to comply with excluded bands of operations according Table 1 of
the FCC Part 15, Subpart G Rules.

The Company also has in place procedures to give prior notification to and to consult with public
safety users in the areas where it plans to deploy its Experimental test systems. It has also sent
written notifications to public safety users in areas where it has longstanding trials under its
Experimental License.

Finally, the Company is focusing its development activity on utility applications that will help
develop a “Smart Grid” for the nation’s electrical infrastructure. In particular, significant work
has been done on integrating the wireless communications, cellular included, with metering
technologies.




                                                 2


Implementation of a Smart Grid will allow more efficient usage of electrical energy and reduce
consumer use, thus mitigating environmental concerns. Implementation of a Smart Grid would
also help secure the electrical power grid. For these reasons, the Company encourages the
Commission to encourage the expansion and implementation of BPL solutions that will help
achieve a Smart Grid
