From the instant the voltage is applied, the rate of change of the voltage is high, and if it was to continue in a linear manner, then V C would reach its maximum value in a time equal to one time constant (T), where T (in seconds) is equal to C (in Farads) multiplied by R (in ohms), see fig 4.3.1. above.
4. Make your reception even bigger with a repeater or a wireless bridge. If your office is inconveniently far from your wireless access point, and you find yourself stretching to the edge of the room to get better reception, install a wireless signal repeater.
WiFi is a wireless networking technology that allows computers, some mobile phones, ipads, game consoles, and other devices to communicate over a wireless signal. The same way a radio can tune into a radio station signal over the airwaves, your device can pick up a signal that connects it to the internet, thru the air. As a matter of fact, a WiFi signal is a high-frequency radio signal.
