Telecommunications equipment and network services provider ZTE has launched the CDMA/LTE dual-mode distributed NodeB system with four transmitters and four receivers (4T4R).
The China-based company claims that the new offering is an industry first. It said ZTE’S Multiple Input Multiple Output (MIMO) technology supports two 2×2 or 4×4 MIMO configurations, allowing 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, said the company.
The distributed NodeB system is based on ZTE’s Soft Defined Radio (SDR) platform to support CDMA2000 1X, EV-DO and LTE.
The SDR technology also makes it possible for Hi3G to do future upgrades of its infrastructure without acquiring new base stations.
ZTE claims that it is the first vendor to achieve seamless and smooth CDMA/LTE integration.
ZTE has shipped over 310,000 CDMA NodeBs as of 1Q 2011. The company leads the global CDMA market with a 32.5% market share.
ZTE CDMA and LTE products general manager Li Jian said the company has led the industry towards the evolution from CDMA to LTE.
She added, "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 utilising the most cutting-edge Uni-RAN platform available."
