To supplement its ongoing open Internet proceeding, the FCC released a public notice on Wednesday that seeks additional comment on two “under-developed” issues: the application of open Internet rules to wireless mobile broadband services and the treatment of specialized services that are carried over last-mile broadband network facilities. Wednesday’s public notice follows the launch of rulemaking proceedings a year ago in which the FCC is considering various regulatory approaches to preserving an open Internet. The proceeding at hand is also related to (but separate from) an FCC inquiry on the regulatory classification of broadband transmission services that was launched in response to the D.C. Circuit Court’s ruling last April in the Comcast-BitTorrent case. The FCC noted that since last year opposing parties have narrowed their disagreement on various key elements that include (1) the use of lawful applications on broadband networks, (2) the ability of users to connect non-harmful devices of their choice to such networks, (3) rules to allow broadband providers to engage in reasonable network management practices, and (4) the imposition of “some form of anti-discrimination protection . . . at least on fixed or wireline broadband platforms.” Acknowledging, however, that last year’s rulemaking notice addressed wireless broadband and specialized services “in less detail than many other issues,” the FCC proclaimed that its analysis of a potential regulatory framework for an open Internet “would benefit from further development of these issues in the record.” As such, the public notice seeks comment on various suggested approaches that could be “employed alone or in combination,” such as (1) truth-in-advertising rules that would prohibit network operators from marketing specialized services as broadband access services, (2) a requirement that specialized service arrangements with vertically-integrated affiliates be offered to third-parties on the same terms and conditions, and (3) limiting specialized services to those that cannot be provided using broadband Internet access service. With respect to mobile broadband, the notice seeks comment, among other things, on transparency and disclosure requirements, approaches to permitting “non-harmful attachment of third-party devices to mobile broadband networks,” and the extent to which “mobile wireless providers [should] be permitted to prevent or restrict the distribution or use of types of applications that may intensively use network capacity.” In a statement, FCC Chairman Julius Genachowski predicted that comments filed in response to Wednesday’s notice, “along with the record developed to date, will help complete our efforts to construct an enforceable framework to preserve Internet freedom.”
