  3. 3. Introduction to ZXSDR  Challenges in the Development of Communication Technology  SDR Concept
  4. 4. Challenge in the Development of Communication Technology  With the increasing communication demands, new technologies come out in succession. The common concern for communication operators and equipment suppliers is how to upgrade equipment more flexibly and protect the investment of operators to greatest extent in the continuous technology updates.  The SDR concept is proposed for this problem.
  5. 5. SDR Concept  The software defined radio (SDR) is defined as radio in which some or all of the physical layer functions are software defined.
  6. 6. SDR Concept  The traditional communication equipment, namely the hardware radio (HR), functions through the hardware. Therefore, functions are often improved by upgrading the equipment. SDR uses the hardware as a general processing platform and functions through the software
  7. 7. Why to Select ZXSDR Series BTS?  ZTE SDR serial BTS are a brand-new series of radio products designed and produced by ZTE. They use the advanced SDR technology and their hardware structure is based on the uniform platform of ZTE, innovatively  supporting multiple radio access methods, including GSM, UMTS, CDMA2000, and WiMAX. In addition, SDR can be smoothly evolved into the Enhanced EDGE/LTE.
  8. 8. Main Features of ZXSDR  High-integrity  Flexible Architecture  Multiple New Functions  Lower Cost
  9. 9. Main Features of ZXSDR  GSM networking mainly uses three types of SDR BTS:  the first is indoor macro BTS 8800  the second is outdoor macro BTS8900
  10. 10. Main Features of ZXSDR the third is distributed BTS in which BBU is at the local end and RU is at the remote end (RRU), such as ZXSDR B8200 GU360 + ZXSDR B8860 GU906/GU186.
  11. 11. High-integrity  Based on the All-IP transmission structure.  Support RU of multiple bands.  BBU supports 60TRX, and RU supports 6TRX/2TRX.  RU60 board supports 6TRX, and RU02 board supports 2TRX.  One fiber supports 24 TRXs.  2G supports a maximum capacity of S666666 or S12/12/12; 3G supports a maximum of 12CS; the dual mode supports a maximum of S333 + S666 (GSM + UMTS).  Support the smooth evolution to LTE and HSPA+
  12. 12. Flexible Architecture  Support the macro BTS and RRU  BBU and RU within a cabinet is called a macro BTS. RRU is called a distributed BTS  Support FE/GE and E1/T1 (IPOE)  Do not support the channelized E1/T1 currently  Support the indoor/outdoor type  Small size, light weight, energy-saving and environment protection  Support the technology evolution
  13. 13. Multiple New Functions  Baseband frequency hopping  Transmit/receive diversity  DDT/DPCT  Multi-carrier combination
  14. 14. Lower Cost  Reduced unit cost  Reduced typical networking cost  Saved ABIS bandwidth  Reduced operating cost  Reduced maintenance cost
  15. 15. Main Differences Between ZXSDR and Traditional 2G BTS  The base band and RF unit are in the same module in V2,3 BTS. ZTE SDR BBU and RU are separated.  lower power consumption .  Capacity
  16. 16. Power Consumption
  17. 17. BB BBU+RRU Architecture:Arch BTS is divided into BBU and RRU. One BBU can provide baseband resources for multiple RRU.itec
  18. 18. Introduction to OMCB A traditional 2G BTS (such as BTSV2 and BTSV3) is configured and managed through OMCR, while the configurations of a SDR BTS should be performed on LMT or OMCB. OMCR is used to configure some radio data. to OMCB
  19. 19. IP Abis Interface  The other major difference for a SDR BTS from a traditional 2G BTS is that the Abis/Iub uses IP protocol. Its physical bearer can be FE/GE or E1/T1 (IP over E1/T1), but not the E1/T1 of TDMBTS can fully use the existing transmission equipment to save the user investment; if FE/GE is used, BTS will obtain more bandwidth, which is oriented to the communication system evolution to all IP.
