A wireless relay apparatus which can provide a wireless relay apparatus compatible with an MIMO system without changing the wiring of an already installed wireless relay apparatus or wireless relay system not compatible with the MIMO system, and which is able to minimize the costs that are generated in installing a wireless relay apparatus compatible with the MIMO system. In this apparatus, a second wireless apparatus (160) is connected to a first wireless apparatus (150) by a coaxial cable (170). The downlink signal wireless unit (111) caries out wireless processing of a downlink signal received at an antenna (102), and in this wireless processing, down-converts the downlink signal received at the antenna (102) to a frequency different than the frequency of the downlink signal received at an antenna (101). The duplexer (115) combines the downlink signal which was subjected to wireless processing at a downlink signal wireless unit (109) and the downlink signal which was subjected to wireless processing at the downlink signal wireless unit (111), and transmits the same using the same coaxial cable (170) to the second wireless apparatus (160).
