Title:
順方向リンク電力制御式リピータ
Document Type and Number:
Japanese Patent JP4267454
Kind Code:
B2
Abstract:
The invention provides a mechanism for automatically setting reverse link gain or power for a repeater (120) used in a communication system (100) through the use of the reverse link power control of a built-in wireless communications device. By embedding a wireless communication device (430, 630, 700) inside the repeater and injecting reverse link signals of the embedded device into the reverse link of the repeater (124A, 124B), the gain of the repeater is maintained relatively constant. The embedded WCD can also be activated on a periodic basis to make calls and utilize reverse link power-control to calibrate or re-calibrate the gain of the repeater, making it a power-controlled repeater.
