OVERVIEW This manual details the Installation and Operation of the Bird Technologies Remote Radio Head System models DDL100/DDL200/DDL300/DDL400. The system is designed to distribute wireless service for voice and data to/from a Master Unit located at the BTS site and to/from the Remote Radio Heads (Remote Units) which are indoor mounted throughout the coverage area. Figure 1 shows an overall layout of a typical installation.
UNPACKING Each major component of the Fiber DAS system is individually packaged and shipped via motor freight or UPS. It is important to report any visible damage to the carrier immediately. It is the customer's responsibility to file damage claims with the carrier within a short period of time after delivery (1 to 5 days). REMOTE UNIT The DDL Remote Unit is a high performing wideband remote radio head equipped with linear variable gain amplifiers supporting 4 operating bands as listed in Table 1.

Make sure the correct branches of the antenna system are connected to the correct front panel connectors or the system will not work properly. Using high quality connectors with gold center pins is advised.
Figure 4: DDL Functional block diagram. RF downlink and uplink signals are found at the four individual RF ports (N-type connector) shown on the right side of the drawing. These are RF signals traveling to and from the users handheld units via the DAS antennas. Uplink signals from the handhelds are passed through the filter assembly and are fed into the uplink side of the respective VGA board.

At the bottom of the page is a button labeled “Locate Me”. When this button is clicked the remote units ON LED, located on the font panel, will blink rapidly for about 1 minute. This is a convenience feature that helps to physically identify units in a large installation. On the right side of the overview screen area is group of drop-down style menu items which allow for detailed interaction with the board. Each band (referred to as an RF Strip) that is found on the board will have a menu item.

Generally all Master Units will contain a master frame unit, a power supply, at least one Base Station Interface Unit (BIU), an RF splitter/combiner unit called the Point of Interconnect (POI) and a minimum of one Fiber Optic Interface card (FOI). A block diagram of the typical Master Unit is shown in Figure 9.

RF patch cables are used to patch the BIU ports to the customers Base Station and the POI Module. Each downlink signal path in the module contains attenuation and filtering. One of the attenuation stages is adjustable and is used to adjust the signal strength to proper levels before feeding the signals into the POI module.
POI Module (Point of Interconnect Module) The POI module contains four independent 1-to-8 splitter/combiners. The module is used in the Fiber DAS system to tie together signals between BIU modules and FOI modules in a multi-band or multioperator system. Each of the 4 independent splitter/combiners has a COMMON port and 8 in/out ports (labeled 1-8).

All connectors between the master unit and the remote unit should be of angled type, otherwise problems with reflections will arise which may cause severe problems in the system. The FOI has a nominal gain of 35 dB. The laser transmitter should see a maximum composite power in of approximately 0 dBm.
