| Research Abstract |
We proposed "Indoor Integrated Wireless Access System" in order to be accessible to any wireless communication terminals. A main idea is that multiple antennas、which are powered the digital signals directly, provide the desired signal field near a terminal given by the spatial composition and spatial filtering effect. Antenna constructing and placement of the basic technologies and calibration methods were studied. Next, the system configuration was also studied and clear guidelines for practical design methods. And "Ubiquitous Ceiling Light"was developed as a demonstration machine.
