Proprietary and Confidential Page 5 6 1 Introduction Radio Hub Unit (RHU) is a part of the Hybrid Distributed Antenna Systems (HDAS) to provide RF link solution between RF Source and Remote Unit (RU). This RHU receives RF signal from antenna or wireline and this unit filters, amplifies and converts RF signal into optic signal and transmits to RU through single mode fiber. RHU is built on a small form factor with four antenna ports for 850MHz, 1900MHz and two GPS antenna ports with the following features: Support for a multi frequency band, multi-technology and multi-carrier Wide band sub-channel selection by digital filter Antenna isolation detection and oscillation protection function Low Power consumption that can be operated by PoE or small AC/DC converter 20dBm Up Link composite power per band SNMP based remote management support Provide signal to remote unit (RU) site as far as 10Km distance via single mode fiber Optic fiber sharing between different carriers AGC (Auto Gain Control), ALC (Auto Level Limit Control) and ADS function Compact and high capacity with scalable design Ruggedized enclosure with more outdoor temperature compliance GPS signal support and transmission with path redundancy function Hybrid DAS RHU is comprised of the following subsystems: FHU (Fiber Hub Unit): Interface unit between RHU and Remote Units, Convert O/E, compensate loss and convert E/O. this unit has optic input port and optic output port. SRU (Small power Remote Unit): Small power (23dBm per band) remote unit for indoor HRU (High power Remote Unit): High power (30 ~ 43dBm per band) remote unit for outdoor MU (Master Unit): Element management server As illustrated in Figure 2-2, Hybrid DAS network is comprised of RHU, FHU and SRU/HRU. RHU provides RUs can transmit signal to coverage area. An optic cable can be shared between different carriers and different band. Intelibs, Inc. Proprietary and Confidential Page 6 7 Figure 1-1 RHU-RU connection configuration Intelibs, Inc. Proprietary and Confidential Page 7 8 2 Product Description Radio Hub Unit (RHU) is a part of the Distributed Antenna System (DAS) to provide link between RF Source and DAS RU, to fill coverage gaps and to enhance the quality of service of extending coverage of mobile service. As shown in Figure 2-1, RHU is a compact platform with the natural heat convection. As unified form factor, RHU services multiple technologies on a single platform with 850/1900MHz Dual-band and GPS L1 band frequencies. It a e ou ted o the all o 9 a k. Va iet of the donor antenna can be used from Yagi directional antenna to high font-back-ratio directional antenna (or panel antenna). Figure 2-1 RHU system 2.1 Network configuration Three band RF signals such as 850/1900MHz and GPS L1 band from link and GPS antenna are fed to RHU and RHU amplifies and converts into optical signal, and transmits this optical signals to remote RU system. RHU can have up to 16 RUs and 5 FHU connections. RHU next release will support 700MHz, 2100MHz. A fiber optic cable can be shared between different carriers or different band. Each frequency band signals are combined to one wavelengths in a single fiber. Table 2-1 describes those wavelength assignments. Maximum allowed optic loss between RHU and RU system is 10 dBo.

Downloading improper images (executable file of repeater CPU) may cause harmful damages to equipment. 4.4 Additional function of RHU 4.4.1 ASD (Auto Shutdown) Function 1. If UL output power level of RHU is above the shutdown level longer than 1 second, RHU automatically turns off amplifier to protect undesirable transmission. 2. During shutdown state, monitor RU input power. If the level is below 5dB from shut down level, turns on UL amplifier automatically. Intelibs, Inc. Proprietary and Confidential Page 39 40 Longer than 1 sec, HPA off 4.4.2 ALC (Auto Limit level Control) Function 1. If UL output power level of RHU reaches the ALC level, RHU decrease the output power to maintain ALC level automatically. 2. When power level goes down under ALC level, RHU increase output power until ALC ATT is 0 by 500msec ~ 1sec speed. ALC Level Power ALC ATT = 0 4.4.3 ALC ATT = δ decrease ALC ATT ALC ATT = 0 AGC (Auto Gain Control) Function 1. In order to have stable output power, RHU has AGC function that can maintain constant output power with setting output level. 2. When input level is decreased RHU increase gain to maintain continuous output level, when Intelibs, Inc. Proprietary and Confidential Page 40 41 input power is increase RHU decrease gain to have same output power automatically. 3. RHU works AGC function by 500msec ~ 1sec speed. ALC Level Power AGC= 0 AGC=δ AGC=0 AGC=0 AGC= δ 4.4.4 Sub-band selection Function RHU can select sub-band up to 10 bands in 65MHz bandwidth using digital filter function. These subband filters have very sharp cut-off characteristics and RHU can provide the signal of selected band of 65MHz BW to coverage area. This digital signal processing function also provide input signal information and antenna isolation information between link and coverage antennas.

The maximum permission Exposure (MPE) for power density of the transmitter operating RF ranges between 300 KHz and 100 GHz. As the Intelibs RHU belongs to the fixed equipment, Analysis has been conducted to evaluate the MPE from the distance greater than 20 Cm as the fixed equipment required. Antenna gain is restricted to 1.5W ERP (2.49 W EIRP) in order to satisfy RF exposure compliance requirements. If higher than 1.5W ERP, routing MPE evaluation is needed. The antenna should be installed to provide at least 20 cm from all persons to satisfy MPE requirements of FCC Part 2, 2, 1091. RU transmits far below that FCC power density restricts. FCC defines power output limits at 20 cm distance for various frequency ranges: Over 300 MHz to 1.5 GHz the limit is determined by frequency /1500 Above 1.5 GHz the limit is 1 mW/cm^2 The basic equation for determining power density is: S = PG/4(pie)R^2 Were S is power density , which is mW/Cm^2 PG, the transmitted power from the antenna identified as EIRP (Equivalent Isotropically Radiated Power) R is the distance of interest from the antenna. Typical Installation Example: As the typical height of a floor is assumed as 10foot high, an average person is assumed 6foot high, the distance from antenna to body is 4 feet (112 cm). For PCS 1900 band, the maximum power output per carrier is assumed 20dBm. With the assumption of 13dBi antenna gain is used, PG in the equation is equal to 33dBm EIRP. Using S = PG/4pieR^2 S = 2/(4*3.14)*112^2 = 12.7μW/cm^2 Also worst case with the assumption of minimum distance of 20 cm according to FCC regulation: S = 2/(4*3.14)*20^2 = 0.4mW/cm^2 Intelibs, Inc.
