    1. Since the operators of part 15 devices are required to cease operation should harmful interference occur to authorized users of the radio frequency spectrum,

      Mention of the operator's duty to prevent interference.

      Language is usually "operator", occasionally "owner or operator"

    1. verify that new software can be legally loaded into a device to meet these requirements

      And this is the required means, that the router vendors prevent loading of software that does not meet the desired ends. Previous documents instead specified that DD-WRT not be loaded.

      The FCC document is no longer available: please see http://web.archive.org/web/20150803065407/https://apps.fcc.gov/kdb/GetAttachment.html?id=1UiSJRK869RsyQddPi5hpw%3D%3D&desc=594280%20D02%20U-NII%20Device%20Security%20v01r02&tracking_number=39498

    2. Device Security

      This is the beginning of the discussion of interest in the FCC's proposal which would ban open source operating systems.

      It should be noted that this is not proposed by the FCC as a ban as such, but rather an effort to keep the devices in question operating within the law and regulations.

      Our concern is it changes the regulations to make it difficult or impossible to use open source or free software operating systems, and that initially it named DD-WRT as an operating system that vendors were to required to prevent from use.

      The document mentioning DD-WRT has subsequently been amended, For the relevant copy, see the Internet Archive at http://web.archive.org/web/20150803065407/https://apps.fcc.gov/kdb/GetAttachment.html?id=1UiSJRK869RsyQddPi5hpw%3D%3D&desc=594280%20D02%20U-NII%20Device%20Security%20v01r02&tracking_number=39498 at the bottom of page 2

    3. The operator of the U-NII device, or if the equipment is professionally installed, the installer, is responsible for ensuring

      A typical example of FCC language assigning responsibility to the operator or their agent.

    4. The instruction manual furnished with the intentional radiator shall contain language in the installation instructions informing the operator and the installer of this responsibility.

      Language re mitigation that should be required of router vendors

    5. The device shall automatically discontinue transmission

      This was a requirement that a particular home router was found to not honour, and which was fixed by Dave Taht. My understanding is that in certain cases it would transmit until a timer ran out... AI DCB to ask Dave

    6. operating frequencies, output power, modulation types or other radio frequency parameters

      Mitigation: IMHO, this section should be split into two, one stating the mission, and one suggesting mitigations in a "not limited to" format.

      In particular, I'd welcome mitigations such as

      • "For devices receiving their geographical location from a network service such as DHCP, the device shall used the specified country as the default location for which to set operating frequencies, output power, modulation types or other radio frequency parameters that are country-specific." and

      • "For all devices using location information to set RF parameters, the purchaser/operator shall be provided with a way of changing the location to the United States.

      • "For all devices where the location is not known, the device shall default to a constructed set of RF parameters that will be legal in at least the United States, and preferably in any country.
