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.

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 can be mounted on the wall or 19” rack.
RHU systems with different operating frequency band can be interconnected via over-the-air. Typical RHU-FHU-SRU/HRU network diagram is depicted in figure 2-2. Figure 2-2 Typical iDAS RHU-FHU-RU network diagram 2.2 External interface ports RHU has all interface connections at bottom side of an enclosure, which includes fiber, antennas and power port.

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.

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.

6 Human RF Exposure – Maximum Permissible Exposure Evaluation The recent FCC developed guideline for evaluation of the human exposure to the RF emissions. 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.
