The Doppler Effect I’m sure you’re quite familiar with the Doppler effect: you send an RF signal at a given frequency to a target, and if this object/person is moving the reflected signal’s frequency will be shifted. This is the reason why a fire truck’s siren has a higher pitch when the truck is going

WiFi 5 also known as 802.11ac has been around for a while now, but few boards have adopted it. The WiFi 5 might easily be confused with the general WiFi (802.11 b/g/n). The WiFi standard 802.11ac is capable of 1300 megabits per second (Mbps) which is the equivalent of 162.5 megabytes per second (MBps), this is 3x faster than
