Page 2: Chapter 1 - Safety Warning
Chapter 1 - Safety Warning Users must follow the below principles: Repeater should follow system requirement communication equipment, assure good groundings and lightning protection. The power supply voltage of repeater should meet the standards security requirement; repeater-operator can operate only after cutting power in advance. -
Page 3: Chapter 2 - Summary
Chapter 2 - Summary In mobile communication, it is inevitable that macro-cell coverage cannot cover weak or dead zones; to use repeater is a good choice in these areas. These band selective repeaters mainly applied in covering small blind and weak zones. -
Page 4: Chapter 3 - Standard And Specification
Chapter 3 - Standard and Specification 3.1 Product description Repeater is essentially a same frequency, transparent and amplify equipment. Inside the single system repeater there are two independent amplify link roads---Up Link and Down Link. DL gets the RF signal by donor antenna from the BTS, amplifies the signal and then transmits to the area to be covered through the coverage antenna. -
