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.
The placement of a Wi-Fi broadband router (or other network gateway device) directly affects its signal reach. 1  Experiment by repositioning your router in different locations that can best avoid physical obstructions and radio interference, two common range limiters for Wi-Fi equipment. Typical sources of these Wi-Fi signal impediments in residences include brick or plaster walls, and microwave ovens or cordless phones in use.
