DIGITAL REPEATER PRODUCT MANUAL DEKOLINK WIRELESS LTD. 2. FUNCTIONAL DESCRIPTION 2.1 GENERAL This repeater is designed to help improve communications signal and coverage by extending the coverage of a base station. The outdoor Donor (Base) antenna receives the signal from a base station and conveys it to the Digital Repeater. The Repeater amplifies the signal. After amplification, the signal is passed through to the Mobile antennas, either outdoor or indoor.
DEKOLINK WIRELESS LTD. PRODUCT MANUAL DIGITAL REPEATER After filtration, the digital signals are converted back into analog signals and up-converted to RF signals by the Up-Converter. The output RF signal is then amplified by a High Power Amplifier, and combined by a duplexer before output. The output signal is emitted by the antennas, either towards the BTS in case of a signal from the mobile handset, or to the Outdoor antenna or to the Indoor antennas array, in accordance with the application.
