Why they can’t just print the antenna’s on PCB just as they do it with mobile phones?
In: Technology
External antennas almost always gives you better signal for the same power and production cost. However the external antennas may be an issue for aesthetics and usability. Especially for cell phones, tablets and laptops that needs to be carried around and put in bags. But a WiFi router is usually mounted out of reach and in a hard to spot place. So you have a much better way to get away with antennas. Some routers even make the antennas an important part of the look of the device. However you do also get WiFi routers with built inn antennas. These are usually a bit more expensive and suffers a bit from reduced performance and higher power consumption.
