Installation Scenario of DBS3900 LTE Application 1 Indoor centralized installation scheme (BBU3900 + RRU + indoor centralized mounting rack) The BBU3900 and RRU are installed on a specific indoor centralized mounting rack next to the antenna. The RRU can also be mounted on the metal post.  The BBU3900 and LRRU can share the power input with the 2G/3G network. 

Installation Scenario of DBS3900 LTE Application 2 BBU3900 installed in a standard 19-inch cabinet When the DBS3900 shares the site with a 2G/3G BTS, the BBU can be installed inside the existing 19-inch cabinet and occupies only 2U space. The RRU can be installed on the tower or at roof next to the antenna.  The BBU and RRU can adopt the power backup system and transmission system of the existing site. Thus, the carrier can provide LTE services at low cost by using the existing equipment of the 2G/3G network. 

 



The BBU and transmission equipment are installed inside the APM30H. The RRU is installed on the tower next to the antenna to reduce feeder loss, thus improving system coverage. The IBBS battery cabinet can meet the increasing requirement for power backup. The TMC11H transmission cabinet can expand the cabinet installation space to 11 U. If no power distribution requirement exists, but the transmission equipment space is limited, the BBU can be directly installed in the TMC11H transmission cabinet.
