WFDS User Manual 1 1.1 System Description Topology of Distribution System Solution based on WFDS The typical topology of distribution system solution based on WFDS is as shown in Figure 1 Figure 1 Topology of WFDS The solution can divided into several parts, signal source, point of interface and WFDS as the distribution system. For downlink signal the point of interface gets the signal from several BTSs and data equipment, then combines them into one signal and feeds Main Unit. Main Unit converts it into optical signal and distributes the signal to Expansion Unit and Remote Unit. The Remote Unit transfers the signal into radio frequency and outputs to the antenna. At each Remote Unit, the operator can set the gain for each system such as GSM, CDMA and 3G independently, which optimizes the coverage for each system and makes future adjustment convenient.

The compendium of function Principle of Work and Specifications Application of RU RU Installation and Power Supply 2.2 The compendium of function The remote unit is an active transceiver which connects the expansion unit or the main unit. RU is the last step in the entire system, and it takes a very important part in the whole system, that is amplifying. RU receives UL fiber optical signal, then it transmitted into the optical module and transform the optical signal into electric signal, after enlargement, it send by the external connection antenna; in a similar way, equipment receives uplink RF signal by the external connection antenna, and amplified in uplink then input to the optical module. Then output the fiber optical signal to the EU (or MU) after the optical module transform the electrical signal to the optical signal. 2.3 Principle of Work and Specifications 2.3.1 Principle of Work The equipment includes the optical module, UL amplifier, DL amplifier, duplexer, monitoring unit and power supplier. DL: RU receives the DL fiber optical signal from the expansion unit or the main unit, then the optical module transmits the optical signal into RF signal. After amplifying, the signal is sent through coaxial cable by the RF antenna. Meanwhile, RU can receive setting and inquiring information from Expansion and Main Unit. TELESTONE Proprietary 2009 TELESTONE. All rights reserved. 3 WFDS User Manual UL: RU receives RF signal from antenna UL transmitted from coaxial cable. Signal is enlarged by low noise amplifier then transmitted by optical modules. And at last optical signal is sent to expansion unit or main unit. The power of the RU is supplied by upper unit. 2.3.2 RU Specifications Dual Mode Remote Unit Specification Description GSM 850MHz:

DC power input here is the DC power supplying for RU, which is supplied by Remote Power Supply. Indicators will show the working status of RU. The DL and UL optical ports are for optical signal from EU or MU. TELESTONE Proprietary 2009 TELESTONE. All rights reserved. 6 WFDS User Manual The RF port is in the rear side of cabinet. Figure 3 RU connector 2.5.2 EU and RU Address Setting EU Address Setting:
Switch dip down means ON The Address of MU does not need to be set The left side of Address from 1-4 dips mean: Each dip shows the cascaded degree of EU. For example, if the dip 1 is on, it means the current EU is placed in the 1st degree of cascaded connection. If the dip 2 is on, it means the current EU is placed in 2nd degree of cascaded connection. (WFDS supports Max two- degree cascaded EU connection) The right side of Address from 1-8 dips mean: The port number of upper equipment connected with current EU. For example, if No.5 dip is on, it means the current EU is connected to the 5th port of upper EU or MU Example:
