6. PART 2 IBS Introduce In the 4G era, The world's operators have found that more than 70% of mobile traffic occurs indoors. In particular, 69% of voice traffic and 90% of data traffic occur indoors, so it can be seen that addressing indoor coverage is very important, and indoor is a very important place

7. PART 2 IBS Introduce Network Structure The indoor coverage system is a successful solution for improving the mobile communication environment for indoor user groups in buildings. Its principle is to utilize the indoor antenna distribution system to evenly distribute the signals of mobile BTSs to every indoor corner, thus ensuring satisfying signal coverage of indoor areas.

8. PART 2 IBS Introduce-Passive+DAS Type of indoor coverage system Wireless Repeater+DAS East to deploy, low cost Improve call quality and reduce call drop rate Suitable for small and medium building or offices

9. Macro Cell Sites for bands 1800MHz , 2100MHz, 2600MHz Dualband 1800+2100+2600 Repeater at 11th Floor Serving antenna distributed in the building via passive DAS. Donor antenna to receive incoming signal from macro cell. Trunk Amplifier at 4th Floor PART 2 IBS Introduce-Passive+DAS How to select the donor antenna 1, use high gain 2, the horizontal direction is narrow beam antenna Because the transceiver of the repeater is the same frequency, it is easy to cause self-excitation, which will cause interference to the network. Generally, the isolation between the donor antenna and the covering antenna is more than 15 dB larger than the overall gain (including the antenna). In the actual operation, on the one hand, try to choose different height antenna; On the other hand, there should be high shielding obstacles or a certain distance between the two antennas as far as possible

10. PART 2 IBS Introduce-Hybrid +DAS Supports 2G/3G/4G/5G (SISO&MIMO) Supports 3GPP Bands from 600~ 40 00MHz - up to 200MHz IBW Supports up tp 1200MHz Transmission Bandwidth on 1 Fiber Core Supports up to 2400MHz Transmission Bandwidth on 2 Fiber Cores Band Selective or Channal Selective Flexibility of Design, Deployment and Expansion Radio CW Test Signal capability CloudDAS (BTS located at different locations) Dynamic Capacity Expansion (sector split) Highlight

11. PART 2 IBS Introduce-Hybrid+DAS 1 Hybrid can realize LTE/5G mimo function Hybrid can be fully extended to achieve 2*2 through the fully coupled access method with the base station. The mimo function improves the coverage effect through dual antennas 2 Deploying Hybrid is faster and has less interference "low power, multiple antennas" approach to achieve fixed point/precision coverage; RF units close to the user end, improve the system's signal-to-noise ratio, and enhance the system Efficiency; monitoring of the entire network to improve maintenance and optimization efficiency; end-to-end design, convenient system adjustment, debugging, and optimization; multi-service solutions to reduce the requirements for passive components of multi-service systems

12. 3 Hybrid is more conducive to expansion Compared with the traditional IBS, the Hybrid system architecture is more convenient to expand, without changing the positions of eu and ru , only the number of MUs needs to be increased. PART 2 IBS Introduce-Hybrid+DAS
