ZTE has announced what it claims is a “milestone development” in the deployment of next-gen, large-capacity wireless networks with the launch of its new ultra-wideband remote radio unit (RRU).
Touted as a “world-first”, the ZXSDR R8978 is a large-capacity TD-LTE eight-channel RF module supporting 100MHz bandwidth (or a maximum of 5 X 20MHz signal bandwidth), which operates in the entire Band 41 frequency of 190MHz.
Using low consumption and broadband RF technologies, the ZXSDR R8978 is designed to help operators who possess broadband spectrum resources with their requirements for ultra-wideband RRUs.
Supporting up to five carrier frequencies, the new RRU includes advanced amplifier technologies such as Crest Factor Reduction (CFR), Digital Pre-Distortion (DPD), Doherty amplifier voltage adjustment and time slot-based intelligent electricity conservation to greatly reduce power consumption.
In addition, the RRU also uses noiseless natural heat dissipation rather than traditional air-conditioner heat dissipation, achieving a 35 percent reduction in power consumption over traditional RRUs.
ZTE has so far built TD-LTE pilot and commercial networks for 48 operators in 33 countries including Europe, Asia-Pacific and Southeast Asia.
