Abstract
A communication system includes a base station configured to transmit and receive a radio wave, and a radio wave refracting plate configured to refract the radio wave transmitted from the base station at a predetermined angle to emit a refractive radio wave, when the radio wave passes through the radio wave refracting plate.
Claims18
A communication system, comprising:
- a base station configured to transmit and receive a radio wave;
- and
- a radio wave refracting plate configured to refract the radio wave transmitted from the base station at a predetermined angle to emit a refractive radio wave, when the radio wave passes through the radio wave refracting plate, wherein
- the radio wave refracting plate is installed in an outdoor space and is configured to emit the radio wave toward an indoor space,
- the radio wave refracting plate is installed on a window glass between the indoor space and the outdoor space, and configured to emit the radio wave toward the indoor space, and
- the radio wave refracting plate is configured according to reflective characteristics of the window glass with respect to the radio wave.
