Telecommunications equipment and network solutions provider ZTE has launched of the CDMA/LTE dual-mode distributed NodeB system with four transmitters and four receivers (4T4R).
According to ZTE, It’s Multiple Input Multiple Output (MIMO) technology with two 2×2 or 4×4 MIMO configurations, allows an increased number of simultaneous data streams, maintenance of coverage over greater distances and faster downloading of data. The MIMO feature helps carriers significantly enhance cell coverage and capacity by improving spectral efficiency, accelerating network deployment and decreasing network construction costs.
This distributed NodeB system is based on ZTE’s large-scale commercial Soft Defined Radio (SDR) platform to support CDMA2000 1X, EV-DO and LTE.
“ZTE has continuously led the industry towards the evolution from CDMA to LTE. ZTE has built an open CDMA/LTE dual-mode laboratory in Dallas, Texas, and deployed CDMA/LTE dual-mode trial networks in many markets — including some in the United States. ZTE is helping CDMA operators evolve to LTE by utilizing the most cutting-edge Uni-RAN platform available,” said Ms. Li Jian, general manager of ZTE’s CDMA and LTE products.
