Microwave data transmission simply refers to the transmission and receiving of electronic data at very high radio frequencies into an area that is separated from the receiving device. Microwave is a form of electromagnetic radiation, which has the ability to transmit data at high bandwidths over long distances. Microwave is usually measured in MHz, megahertz, or GHz, and is often used for communication systems in mobile devices. Microwave is also used for entertainment systems such as DVD players and television.
The major benefit of using microwaves for communication is that the signals are much stronger than other methods, such as radio or TV signals, which means that they can carry much farther. Also, microwave data transmission is faster than other means. However, in order to send or receive microwave signals over a large distance, it is necessary to have multiple transmitters instead of just a single receiver, because each one must be receiving and transmitting at the same frequency. Microwave signals are also not affected by the atmosphere, which means that they can travel over great distances and remain undisturbed.
The first embodiment of the present invention provides for the use of a hand-held device, with a push button on the handle for initiating microwave data transmission. The device is capable of automatically detecting an appropriate frequency and activating the transmitter when it is detected. In order to allow the user to gain access to the necessary software and control for the second embodiment, the hand-held device may include a touch screen display, with a pointer finger for selecting the necessary frequency and pressing the send button. This allows the user to send one’s own frequency to up to three receivers. This is done by scanning the finger of the user for a specified point on the screen and then transmitting that point on the appropriate channel. This second embodiment of the present invention thus allows the user to receive a signal even when the user is unable to see the signal from the first transducer.
