Introduction to ZXSDR

Challenges in the Development of Communication Technology

SDR Concept

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.

SDR Concept

The software defined radio (SDR) is defined as radio in which some or all of the physical layer functions are software defined.

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

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.

Main Features of ZXSDR

High-integrity Flexible Architecture Multiple New Functions Lower Cost

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

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.

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+

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

Multiple New Functions

Baseband frequency hopping Transmit/receive diversity DDT/DPCT Multi-carrier combination

Lower Cost

Reduced unit cost Reduced typical networking cost Saved ABIS bandwidth Reduced operating cost Reduced maintenance cost

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.

BB BBU+RRU Architecture:ArchBTS is divided into BBU and RRU. One BBU can provide baseband resources for multiple RRU.itec

Introduction to OMCBA 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

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.
