1.1 Product Positioning
Market Positioning
The ZXSDR BS8922, which is an LTE product, is an integrated outdoor micro base station. The ZXSDR BS8922 covers dead spots and hot spots to supplement macro-networks effectively.
The ZXSDR BS8922 has lower requirements for site selection and installation than macro base stations, and can be used for rapid base station construction to reduce costs. The ZXSDR BS8922 is applicable to installation scenarios with no equipment rooms, transmission resource shortage, or limit on equipment size and weight.
Position of the ZXSDR BS8922 in a Network
Figure 1-1 shows the position of the ZXSDR BS8922 in a network. The red dotted-line indicates the data flow when the ZXSDR BS8922 acts as a traditional micro base station.

ZXSDR BS8922 Product Description
It supports expansion to S1/1/1 with 3 units. 2×5 W TOC and close to antenna installation improves coverage. Compared with traditional indoor, hot spot and rural coverage solutions, it provides higher capacity and coverage.
•High Integration
Small size, light weight, and easy installation Integrated antenna design, and easy deployment
•Unified Platform
The ZXSDR BS8922 uses the unified SDR platform, supports smooth evolution to future technologies, and reduces the operator investment.
•Green eNodeB
The ZXSDR BS8922 supports Doherty, Digital PreDistortion (DPD) and MCPA technologies in power amplifier module which provides high Power Amplifier (PA) power efficiency. High efficiency MCPA, natural convection cooling and high density design reduce the power consumption. Zero noise pollution makes it easy for indoor and outdoor installation.
•IP RAN and Rich Interfaces
It provides FE/GE interfaces, and supports various transmission modes such as PTN/PON microwave.
