Wireless Cellular Repeater Preface This user’s manual describes the installation, commissioning and maintenance of JD60-7-TB-US Wireless Cellular Repeater. Please do read the user manual carefully before installing and maintaining the triple band repeater. The information in this manual is subject to change without prior notice Opinions are welcomed about the manual improvement. -
Page 4: Why Repeater
User Manual Wireless Cellular Repeater 2. Why repeater 2.1. Reason 1 1) Blind or weak signal areas are formed if the buildings are too far away from BTS, or the buildings themselves shield or absorb the signals. 2) There are too many complicated signals in the higher part of the buildings, therefore ping-pong switching effect has been formed and the signals fluctuate a lot, there are annoying noises during phone calls and there are dropped phone calls accordingly. - Page 5 The maximum power level of JD60-7-TB-US is 0.01~0.1W, and it decreases to be maximum 0.003W when reaching server antenna. And since the server antenna is installed over the ceiling or onto the wall, there are usually more than 3 meter away from the human body, 3meter away means at least 40dB propagation loss, or 10000 times less, 0.0000003W, therefore it is too weak to influence human bodies though it is still a very good...

User Manual Wireless Cellular Repeater 8. Installation The triple band repeater micro repeater should be used to cover the area indoor and the humidity and temperature of working can affect the reliability of repeater. So, temperature, humidity, dust, interference, power, space requirements and other factors should be considered during installation of repeater. - Page 15 User Manual Wireless Cellular Repeater recommended the donor antenna to be installed in an attic. Testing the signal strength received from donor antenna mounted in site by mobile phone: Please select the top of the building to install the donor antenna if the total floors are less than 7, and must select a place like balcony or platform lower than 7th floor for the donor antenna if the buildings are over 7 floors.
