Error detecting device for a radio blind zone system |
摘要 |
In a radio blind zone system, a master unit and a slave unit are respectively situated at an existing station and a radio blind zone and connected together by a coaxial transmission path. The master unit feeds a load current to the slave unit which includes a relay amplifying device or a tower-top amplifying device. The master unit is capable of detecting an error occurred in the slave unit by detecting a change in the load current applied to the slave unit.
