                             Experimental License WD2XEQ
                             File No. 0 132-EX-AR-2007
                             Opposition to ARRL Informal Objection

Dear Mr. Knapp:

       On behalf of Ambient Corporation ("Ambient" or the "Company"), we hereby oppose the
July 25, 2007 Informal Objection filed by ARRL relating to the application for renewal of
Experimental License WD2XEQ filed on August 1, 2007. For the reasons set forth below, we
request that the Informal Objection be dismissed or denied and Ambient's renewal application
granted.

        1.      We strongly object to ARRL's attempts to undermine the rapid and widespread
development of promising and innovative broadband technologies under the FCC's new Access
BPL rules, as contrary to the FCC's statutory mandate in Section 706 of the Telecommunications
Act of 1996 ("Act"), 47 U.S.C. 5 157. The claims which ARRL is attempting to raise with
respect to our experimental operations plainly involve its fundamental opposition to FCC rules
and policy regarding interference mitigation and other technical requirements of general
applicability to the Access BPL industry. Not surprisingly, many of these same matters are the
subject of claims which ARRL has made in challenging the FCC's decisions in its Report and
Order (FCC 04-245) in ET Docket No. 04-37103-104 and in its Memorandum Opinion and
Order (FCC 06-1 13) on reconsideration in ET Dkt No 04-37103-104, now on appeal in the D.C.
Circuit (Case No. 06-1343). Ambient has intervened in support of the FCC in that appeal
because we believe that the FCC acted reasonably and within the scope of its statutory authority
in adopting its new Access BPL rules, and because we believe Access BPL technologies have the
potential to provide the numerous consumer benefits which the FCC foresaw in adopting these
rules.

       2.    ARRL claims that ienewal of Ambient's Experimental License to continue
development of more advanced and improved Access BPL devices and systems is not justified.

These claims, however, ignore the FCC's statutory mandate under Section 706 of the Act, the
findings which the FCC made in adopting its Access BPL rules, the justification which Ambient
provided when its Experimental License was most recently updated, and the numerous Progress
Report submissions which Ambient has made to keep the FCC apprised of its device and
software development activities under its Experimental License.

       Ambient's extensive experimental testing program has 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. In September of 2006, Ambient was one of
the first companies to receive a grant of BPL Equipment Authorization demonstrating
compliance with the FCC's new Access BPL requirements, FCC IDENTIFIER: SPKBHPLCAA,
Equipment Class: Access Broadband Over Powerline System, X2 PLC NODE. Development
and testing of the overhead configurations of these advanced devices took place at the
Company's Briarcliff Manor facilities.

         As previously described in its Progress Report submitted August 1, 2007, Ambient has
made additional advances in its software and hardware to develop new generations of products
which fully address all applicable regulatory requirements. Under its experimental program, it
has continued to implement several Class I permissible changes based on testing conducted at
Briarcliff Manor. Additional testing has been completed at the Company's Briarcliff Manor
facilities in preparation for the submission of a Class I1 permissible change expected in the near
future. The Company's numerous software and hardware achievements are summarized in the
attached Exhibit A.

        In addition, Ambient recently completed a one-year test program under contract for New
York State Energy Research and Development Authority (NYSERDA) which is being operated
over the Company's legacy BPL system. Specifically, Ambient and Consolidated Edison were
awarded a research and development grant by NYSERDA in March of 2006. The scope of the
project was to determine if the BPL network could help improve service to customers by
continuously monitoring the electrical distribution system, as well as portions of customers'
electrical equipment, and identiwpredict power quality problems throughout the system. These
improvements will serve the public interest by reducing electricity waste and improving
customer service.

        Ambient is continuing research to enhance its BPL system with additional applications
such as current and voltage sensing, which will enable utilities to better monitor their distribution
systems. This is accomplished without any additional equipment beyond the BPL equipment.
This capability is important to utilities because it minimizes the amount of equipment that must
be added to already congested utility poles. This development activity is also intended to be
integrated with utility applications that will help develop a "Smart Grid" for the nation's
electrical infrastructure. 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. Ambient's
goals in this aspect of its experimental research and development program are compelling

evidence of the extraordinary benefits which can be fostered by granting Ambient's application
to be able to continue experimental operations.

       3.    The national scope of its Experimental License enables Ambient to develop, test,
and demonstrate in different geographical areas as well as on different utility systems and
topologes. As described in its Progress Reports, Ambient continues to have requests for testing
systems fiom a number of power companies around the country. The nationwide scope of
Ambient's Experimental License is needed to continue this important aspect of the development
of Access BPL capabilities.

       For example, Ambient has ongoing tests as follows:

       The MVILV test system with Orange and Rockland Utilities Inc. ("O&R") at Monsey,
       New York reported in the Company's previous Progress Reports is unchanged and
       remains in operation.

       Ambient entered into a BPL Trial Agreement with San Diego Gas & Electric Company
       (SDG&E), a unit of Sempra Energy (NYSE: SRE), to evaluate BPL-enabled consumer
       and utility based applications.

       Ambient has a BPL Trial Agreement with FirstEnergy Corporation to install Ambient
       Access BPL system (84 units) on 4 medium voltage circuits in Brimfield, Ohio.

       Ambient entered into BPL Trial Agreement with Entergy Corporation. This Access BPL
       system includes up to 18 units on two separate medium voltage circuits in and near Little
       Rock, Arkansas.

        Cooperation and collaboration by power companies is essential for future BPL
commercial deployments. Power companies continue to want on-site demonstrations to gain
familiarity with equipment compatibility, functionality on their systems, and the range of
potential consumer and operational benefits which they can provide. From an engineering
development viewpoint, there is significant useful information obtained from testing of the
emissions compliance of its equipment designs on various power systems and settings, which
may involve different types of distribution topologies, geographies and may be affected by
different environmental or other factors.

       4.     As previously reported to the FCC, Ambient has conducted its Experimental test
program so as to meet all its responsibilities under the FCC's rules and the terms of its
Experimental License. Primary among these responsibilities is its duty to protect licensed users
from harmful interference.

         The individuals within the Company who are responsible for defining and implementing
its test programs are highly qualified to anticipate, address and resolve interference issues:

       Dr. Yehuda Cern, its Chief Engineer, who is also Vice Chair of IEEE Working Group
       P1675, is working on the draft "Standard for Broadband over Power Line Hardware and
       Personnel Safety" which has been completed and is now in preparation for balloting
       shortly.

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

       Ram Rao, the Company's Chief Technology Officer, and Aron Viner, who are also
       members of IEEE P1901, the BPL MAC/ PHY Standard Working Group, and are
       participating in the development of a "Standard for Broadband over Power Line
       Networks: Medium Access Control and Physical Layer Specifications."

       As previously reported to the FCC, the Company has notched out its signals on Amateur
bands, demonstrating significant advancements in its technology over the relatively short time
period since the FCC adoption of its Access BPL requirements. 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, 10.1-10.1 5 MHz, 14.0-14.35 MHz, 18,068 -1 8,168 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. For example, notification letters were sent to all public safety
users within a 10 kilometer radius of the Briarcliff Manor test facilities. Ambient has never
received a single complaint from public safety users regarding interference. Ambient has sent
similar notification letters in areas in which it has longstanding experimental operations.

        5.     Prior to the grant of Ambient's current Experimental License, ARRL had filed
complaints alleging harmhl interference to mobile amateur operations in the Briarcliff Manor
area. As shown in the record of correspondence with the FCC, the Company was unable to
confirm that its facilities were causing harmhl interference as ARRL claimed. In fact the FCC
concluded, based on its own testing, that its engineers " ... did not observe any BPL signal levels
or effects from the Ambient Corporation Briarcliff manor BPL operations that appeared to have
the potential to seriously degrade, obstruct or repeatedly interrupt mobile amateur
communications at the specified addresses." See Letter of Bruce Franca dated February 10,
2005.

       The Enforcement Bureau inquiry in May 2007 is the only other pending proceeding
before the Commission on this issue, and Ambient has fully responded to the Enforcement
Bureau's inquiry and taken steps to ensure that its equipment remains in compliance. See our


    Julius Knapp, Chief

    Page 5

    Progress Report submitted August 1, 2007 and the attachments thereto. As stated in that report,
    Ambient has voluntarily shut down all of its legacy equipment and is replacing it with second
    generation equipment. Ambient anticipates that the replacement of all legacy equipment with
    second generation equipment will be completed by August 21,2007.

           The upgraded network will have added interference avoidance features, such as deeper
    and cleaner notches - more than 35 dB below Part 15 limits. This deeper notching capability
    provides nearly twice the depth of the FCC required depth of 20 dB notches. In addition, the
    upgraded network in Briarcliff Manor will provide Ambient with experimental data from diverse
    geographical and distribution system topologies.

        6.      ARRL's Informal Objection includes a letter from a member of the Westchester
County Board of Legislators, Mr. William E. Burton. The Burton letter, on its terms, indicates
that Mr. Burton is not acquainted with the FCC's prior finding that Ambient's facilities comply
with its rules and policies. Mr. Burton also alleges that Ambient has applied for renewal of its
license "without making vitally important improvements in its technology." However, as clearly
demonstrated herein, that is untrue. Furthermore, Mr. Burton appears unaware that legacy
equipment has been voluntarily shut down and that replacement with second generation
equipment is ongoing and will be finalized shortly. Nor have we received any complaint of any
interference to any fixed amateur radio operation, nor are we aware of any instance in which an
amateur RACES communication was interfered with.'

       Mr. Burton surely must appreciate and understand the value of BPL technology in
support of important and viable public safety measures, such as monitoring the security and
operation of the electricity grid. The goal of making that technology available to utilities is the
underlying purpose of the experimental operations permitted by the Experimental License. It
would be a disservice to public safety to inhibit or block the experimental testing necessary to
develop, improve and implement this public safety technology.




                                               A2/k(
       For all of these reasons, Ambient urges OET to dismiss or deny ARRL's Informal
Objection and grant the renewal application.
