Publication number: 20100165892Abstract: Disclosed is an apparatus and a method for implementing efficient redundancy and an expanded service coverage in a Radio Access Station (RAS) system. In the RAS system, if the main processor unit generates switching control signals in response to the sensed failures on sensing a failure in any of the channel cards and the transceivers or a failure in any of the high-power amplifiers, all supporting M (i.e., the number of FAs equal to or more than three) and K (i.e., the number of sectors equal to or more than three), between the transceivers and the predetermined Time Division Duplex (TDD) switches connected to the antennas, the RF switch unit switches a path based on the generated switching control signals so as to substitute the failed module either by one additional redundancy transceiver per M and K or by one additional redundancy high-power amplifier per M and K. As a result, an efficient N+1 redundancy structure is embodied.Type: ApplicationFiled: February 26, 2007Publication date: July 1, 2010Applicant: POSDATA CO., LTD.Inventors: Young-Jae Cha, Mun-Kyu Lee
