  • A Letter to the FCC [PDF]
    Before the FEDERAL COMMUNICATIONS COMMISSION Washington, DC 20554 In the Matter of ) ) Amendment of Part 0, 1, 2, 15 and 18 of the ) ET Docket No. 15­170 Commission’s Rules regarding Authorization ) Of Radio frequency Equipment ) ) Request for the Allowance of Optional ) RM­11673 Electronic Labeling for Wireless Devices ) Summary The rules laid out in ET Docket No. 15­170 should not go into effect as written. They would cause more harm than good and risk a significant overreach of the Commission’s authority. Specifically, the rules would limit the ability to upgrade or replace firmware in commercial, off­the­shelf home or small­business routers. This would damage the compliance, security, reliability and functionality of home and business networks. It would also restrict innovation and research into new networking technologies. We present an alternate proposal that better meets the goals of the FCC, not only ensuring the desired operation of the RF portion of a Wi­Fi router within the mandated parameters, but also assisting in the FCC’s broader goals of increasing consumer choice, fostering competition, protecting infrastructure, and increasing resiliency to communication disruptions. If the Commission does not intend to prohibit the upgrade or replacement of firmware in Wi­Fi ​ ​ devices, the undersigned would welcome a clear statement of that intent. Introduction We recommend the FCC pursue an alternative path to ensuring Radio Frequency (RF) compliance from Wi­Fi equipment. We understand there are significant concerns regarding existing users of the Wi­Fi ​ spectrum, and a desire to avoid uncontrolled change. However, we most strenuously advise against prohibiting changes to firmware of devices containing radio components, and furthermore advise against allowing non­updatable devices into the field.

Linux is being deployed into a much wider array of devices than Linus Torvalds anticipated when he was working on it in his dorm room. The variety of supported chip architectures is astounding and has led to Linux in devices large and small; from huge IBM mainframes to tiny devices no bigger than their connection ports and everything in between. It is used in large enterprise data centers, internet infrastructure devices, Building Embedded Linux Systems personal development systems. It also powers consumer electronics, mobile phones, and many Internet of Things devices. When building Linux software for desktop and enterprise-class devices, developers Building Embedded Linux Systems use a desktop distribution such as Ubuntu on their build machines to have an environment as close as possible to the one where the software will be deployed. Tools such as VirtualBox and Docker allow even better alignment between development, testing, and productions environments. Wikipedia defines an embedded system as: "A computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. I find it simple enough to say that an embedded system is a computer that most people don't think of as a computer. Its primary role is to serve as an appliance of Building Embedded Linux Systems sort, and it is not considered a general-purpose computing platform.
