Abstract

This idea is about a Wireless Signal Blocker (WSB). The WSB has transmitter at the entrance of a facility where the sounds for pagers or the cell phones needs to be controlled. For example: At the door of a class room, a court room, or a church, a transmitter that transmits certain waves. This transmitter blocks any wireless signals from coming to that area. A cell phone/pager is not able to get any signal, and is not able to cause any disturbance or inconvenience in that area. The implementation of this idea is very simple and easy, following are some implementation methods:

(W)ireless (S)ignal (B)locker: WSB for Pagers and Cell phones

    This idea is about a Wireless Signal Blocker (WSB). The WSB has transmitter at the entrance of a facility where the sounds for pagers or the cell phones needs to be controlled. For example: At the door of a class room, a court room, or a church, a transmitter that transmits certain waves. This transmitter blocks any wireless signals from coming to that area. A cell phone/pager is not able to get any signal, and is not able to cause any disturbance or inconvenience in that area. The implementation of this idea is very simple and easy, following are some implementation methods:

Requirements:
1. A calibrated and tested transmitter (WSB) is placed in a room or area where the signals are to be controlled.

      1.1 Be able to control the strength of a signal is needed to cover an entire building or just a room. A transmittal wave strength calibration tool is required to control the frequency and strength of the signal.

2. The WSB frequency and the area controlled by this transmitter can be controlled and changed by an operator.

      2.1 The operator can turn a knob on of the calibration frequency tool to select the frequency range to block.

2.1.1 The operator can turn a knob on the calibration frequency tool to select the strength

of the signal.

3. The signal strength of the WSB is determined by a calibration receiver beeper device.
3.1 The receiver makes a noise or beep when a signal is received from the strength cali...
