-There is the perpetual endeavor of making the Linux kernel work on possibly any piece of hardware available. A part of this work takes place inside of projects like OpenWrt, but also inside of the companies that design, manufacture or vend the hardware respectively products based upon it. More or less of this work sooner or later ends gets mainlined, i.e. the code becomes part of the mainline Linux kernel.+The perpetual effort to make the Linux kernel work on any piece of hardware available is ongoing. This work takes place within projects like OpenWrt and also within companies that design, manufacture, or sell hardware and products based on Linux. Much of this work eventually gets mainlined, meaning the code becomes part of the mainline Linux kernel.
  
-Whereas of today we take it for granted to have wireless functionality as a convenience everywhere around us, in the beginning, it was a royal PITA. The IEEE 802.11 family of standards fired the imagination of what could be realized with it, BUT the available [[wp>Device driver|driver]]s for the Linux kernel were poorly written, lacked features or were non-existent. This is actually still true for some of the wireless hardware sold on the market. No matter how fantastic or potent it may be, its Linux drivers don't offer much. +Today, we take wireless functionality for granted, but in the beginning, it was a real challenge.

-From its foundation on OpenWrt has been focusing on CPE hardware such as routers or NAS, and much dedication was invested to support IEEE 802.11 as extensively as possible. Given that the initial hardware, the Linksys WRT54G, was sold about 400,000 times in the first months, it is safe to assume that the work done by the OpenWrt project had an impact.+

 Most SoC manufacturers license a (soft or hard) [[docs:techref:hardware:cpu#IP core|IP core]] for a certain [[docs:techref:hardware:cpu|CPU]] design from a licensor like MIPS or ARM, then combine this with other (self-developed or licensed) (soft or hard) [[docs:techref:hardware:cpu#IP core|IP cores]] for DSP-, wireless-, VoIP-, Sound-, Switch-, etc-functionality and commission the manufacturing of Chips at some semiconductor foundry. These Chips, SoCs, are acquired by different manufacturers of Routers. The latter design [[wp>Printed circuit board|PCB]]s for whatever purpose and solder the purchased chips (SoC, RAM, Flash) onto them. Most SoC manufacturers license a (soft or hard) [[docs:techref:hardware:cpu#IP core|IP core]] for a certain [[docs:techref:hardware:cpu|CPU]] design from a licensor like MIPS or ARM, then combine this with other (self-developed or licensed) (soft or hard) [[docs:techref:hardware:cpu#IP core|IP cores]] for DSP-, wireless-, VoIP-, Sound-, Switch-, etc-functionality and commission the manufacturing of Chips at some semiconductor foundry.
