Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for controlling a communication device.
Background
Wireless transmission has many advantages over wired transmission. Perhaps most importantly, it is more flexible. Wireless signals can be sent from one transmitter to many receivers without the need for cables. All wireless signals are transmitted through the air along with electromagnetic waves, and the electromagnetic waves are energy waves consisting of an electronic part and an energy part.
Like wired signals, wireless signals are also derived from electrical currents transmitted along conductors. The electronic signal arrives from the transmitter at the antenna, which then transmits the signal as a series of electromagnetic waves into the air. The signal propagates through the air until it reaches the target location. At the target location, another antenna receives the signal and a receiver converts it back into a current; each wireless service requires a specially designed antenna. The specifications of the service determine the power output, frequency and radiation pattern of the antenna. The "radiation pattern" of an antenna describes the relative lengths over a three-dimensional region of all electromagnetic energy transmitted or received by the antenna. A "directional antenna" transmits radio signals in a single direction. Such antennas are used when a source needs to communicate with a target location (e.g., in a point-to-point connection). Directional antennas may also be used when multiple receiving nodes are arranged in a line. Alternatively, it may be used when it is more important to maintain the strength of the signal over a distance than to cover a wider geographical area, because the antenna can use its energy to transmit signals in more directions, as well as longer distances in one direction. Some examples of wireless services using directional antennas include satellite downlinks and uplinks, wireless LANs, and space, sea, and aviation missiles;
however, the wireless communication needs to consider various factors such as obstacles and power, and therefore, how to control the communication device of the wireless communication to improve the stability of the communication needs to be considered.
