peaters driving passive distributed antenna systems (DAS) often become impractical due to their coaxial cable loss. ClearFill Space1 is offering great value because the sig nal loss in fiber is extremely low compared to coaxial cable. ClearFillSpace1 can provide excellent coverage over broad areas. ClearFillSpace1 is a mid power indoor coverage solution that meets any RF distribution needs from simple entry-level systems to the most complex applications. ClearFillSpace1 is a modular RF -over-fiber distribution system that provides reliable and highest quality indoor coverage of 2G and 3G wireless services in airports, hospitals, ca m-
pus, enterprises, convention centers, high-rise buildings and tunnels. The ClearFillSpace1 system is a plug-and-play fiber-optical repeater system consisting of two main components: a Master Unit (MU) and Remote Units (RU), connected via a fiber -
optical link(s). L-MU series Master Unit L-MU1 drives one remote unit (band selective) L-MU2 drives two remote units (band selective) L-MU4 drives four remote units (band selective) Figure 1 Master unit L-MU of ClearFillSpace1 Three types of RF broadband MU are feeding one, two or four RU providing high level of flexibility.

RU and MU build up an end-to-end RF system connected via a pair of optical fib er. See User Handbook of Master Unit (L -MU series) for additional information about MU. The system MU -RU and its plug -and-play functionality is designed to operate for typical DAS applications with nominal UL input signal strengths (into RU RF in/out port) in the range of -55 dBm to -35 dBm. As every distributed RF-over-fiber system , ClearFill Space1 introduces signal d e-
lays in DL and in UL due to the use of single-mode optical fibers between MU and RU. This delay has to be taken into account by cellular network planning/operation for appropriate setting of BTS/NodeB search windows . This also applies for remote BTS/NodeBs which may be connected to a ClearFill Space1 system over-the-air using an off -air repeater with donor antenna . Establishing a connection between mobile / handheld device and BTS/NodeB may fail due to of improper setting of search window / range. CONFIDENTIAL PROPRIETARY Reg.

In downlink, an optical r eceiver ORx converts the optical input signals from the Optical Master Unit to RF signals. The BP/LP separates RF communications signals from the monitoring pilot tone. A cascade of amplifiers provides sufficient RF gain imbedded in an ALC which keeps the output power level constant compensating optical losses of the opt i-
cal link. The duplexer separates downlink output signals from uplink input signals. In uplink, the RF amplifier is embedded in an ALC, which compensates varying input power levels. The out put power into the laser OTx is limited protecting the laser against damages. The BP/LP module combines the RF signals with the pilot tone in UL. CONFIDENTIAL PROPRIETARY Reg.

Duplexer Optical Module Uplink path Pilot Tone Monitoring PSU RF N- Connector Monitoring LED Downlink path SC/APC Optical IN / OUT Connectors AC Power Cable Earthing Clamp Figure 7: Inner arrangement of the Remote Unit The optical transceiver and the power supply are separate modules. The pilot tone mon i-
toring, downlink, uplink and the duplexer are integrated on one PCB. All modules of the RU are integrated in a cast housing with integrated heat sink d esigned for wall mounting. The housing has a protection against splash water, dust and dirt. All connections are a r-
ranged on the bott om side. The attractive design and the protection class IP 54 allows i n-
stalling the RU in various environments. 3.2.1 Uplink The uplink path mainly consists of a four -stage amplifier with two integrated filters, an ALC and a limiter to protect the laser in UL against high power levels and to avoid non -linear operation. CONFIDENTIAL PROPRIETARY Reg. No.: User Handbook 1100182-C.DOC Page 14 of 29 User Handbook L-RU Revision C The ALC compensates for different uplink input levels per carrier providing optimised UL performance with regard to spurious free dynamic range. 3.2.2 Downlink The downlink path includes a five-stage amplifier with balanced power amplifier, filters and an ALC, which automatically operates the RU according to ETSI requirements. The downlink path is equipped with a mon itoring to control the RF -amplifiers. Each amplifier stage can generate an alarm by controlling the DC-current. 3.2.3 Monitoring All amplifier stages in downlink and uplink as well as the optical tran sceiver are monitored. Failures are logically combined to a resulting summary alarm that results in a switch -off of the pilot tone. The alarm matrix of the RU is shown in Table 1 below. Alarm Power supply Summary alarm (RF am-
plifiers, optical modules) LED Main Power Monitoring OK green green Failure Off red Table 1 Alarm matrix of the RU 3.2.4 Function of ALC The main part of this ALC system is a detector circuitry. It converts an RF signal to an equivalent DC voltage at its output. The detected voltage is compared with a reference value adjusting an electrical controlled attenuator. Thus, the RF power level at the antenna port is kept constant to maximum and no manual leveling is required. 3.2.5 Duplexer The duplexer at the antenna port is a high performance ceramic duplexer separating uplink and downlink RF-bands.

As long as the unit is kept away from ext reme temperatures and moisture, it should provide long -term, carefree operation. It is strongly reco mmended that no invasive procedures are performed on the unit in an attempt to verify performance. See section variation checks. 7.2 for recommen ded routine performance 7.2 Routine Checks Although the RU is a low -maintenance unit, it is recommended to routinely verify the pe r-
formance of the RU by making test calls or detailed system checks on the actual radio coverage. Several test calls should be made at different positions within each area to get an overall picture of the system performance. This is by far the best way to check the sy s-
tem as it tests the whole system from an operational viewpoint as seen by the users. It is strong ly recommended that no i nvasive procedures be performed on the unit in an attempt to verify performance unless a serious problem with performance has been ident i-
fied as described above. Any such inv asive procedures are more likely to do damage to the system and create intermittent performance than to be of any practical value. 7.3 Repair Repairs may only be carried out by qualified personnel that are familiar with both the ha z-
ards involved and the relevant statutory regulations. Unauthorized modifications or repairs invalidate the warranty claim. Before contact RFS customer service for repair request please prove the checklist in se c-
