摘要： An extension subordinate machine system enabling high-accuracy correction of the cable loss by adjusting the gain by using the pilot signal and further enabling high-accuracy correction of the loss caused by distribution by a distributor even when a relay device adaptor is connected to the extension subordinate machine through the distributor. With this system, a main machine control section (201) outputs a pilot signal generated by a pilot signal generating section (203) when a switching section (205) sets a measurement mode. A pilot detecting section (215) detects the reception level. A control section (216) detects the pilot signal and sets the attenuation factor according to the reception level of the detected pilot signal. A variable attenuator (206) attenuates the up-link signal and the down-link signal at the set attenuation factor to adjust the gain.

摘要： A plurality of radio access units (108-1 to 108-n) form the single cell (#120) of a first communication system, while forming respective individual multi-cells (#130-1 to #130-n) of a second communication system within the single cell (#120). The plurality of radio access units (108-1 to 108-n) transmit a downstream signal of the first communication system input from a main unit (107) to a terminal using the first communication system of the single cell (#120), while each transmitting a downstream signal of the second communication system input from the main unit (107) to a terminal using the second communication system of the corresponding respective one of the multi-cells (#130-1 to #130-n).

摘要： 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).
