1. A wireless testing system to be used with a room capable of electromagnetic radiation shielding for measuring a three dimensional radiation pattern of a wireless module that is placed in the room and that operates dependently, the room having a Cartesian coordinate in three dimensions consisting of a first axis, a second axis and a third axis that are mutually orthogonal, the wireless testing system comprising:

  • a main computer disposed outside the room and electrically coupled with the wireless module, the main computer being configured to control the wireless module to transmit or receive a wireless signal;

    a rotary mechanism disposed in the room, said rotary mechanism being controlled by said main computer and including;

    a rotatable seat having a first rotation axis extending in the direction of the third axis and controlled by the main computer to rotate about the first rotation axis,a support arm disposed on the rotatable seat and extending in the direction of the third axis, anda module rotating arm disposed on the support arm and spaced apart from the rotatable seat, the module rotating arm being configured to hold the wireless module and position the wireless module at or in the vicinity of the first rotation axis, and having a second rotation axis extending in the direction of the first axis, the module rotating arm being controlled by the main computer to rotate the wireless module about the second rotation axis;

    an antenna disposed in the room in a manner that the antenna is substantially directed toward the wireless module;

    a measurement device disposed outside the room, the measurement device being coupled to the main computer and the antenna, and being controlled by the main computer to control the antenna to receive or transmit the wireless signal;

    a remote computer disposed in the room, the remote computer being electrically coupled with the main computer and with the wireless module, and being controlled by the main computer to control the wireless module to transmit or receive the wireless signal; and

    a shield box disposed in the room to contain the remote computer therein and for shielding electromagnetic radiation from the remote computer.
