ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly-listed global provider of telecommunications equipment, network solutions and mobile devices, today announced the launch of ZXSDR R8978, the first ultra-wideband remote radio unit (RRU) available in the industry globally.

In a milestone development that will enable the deployment of next-generation, large-capacity wireless networks, the ZXSDR R8978 is the industry’s first large-capacity TD-LTE eight-channel RF module that supports 100MHz bandwidth. It can operate in the entire Band 41 frequency of 190MHz. Supporting a maximum of 5 X 20MHz signal bandwidth, the ZXSDR R8978 is the first base station device globally that complies with the LTE-Advanced requirements for over 100MHz operating bandwidth.

Many TDD operators globally possess broad band spectrum resources – for example: Clearwire in the United States. In China, the entire 190MHz spectrum of 2500-2690MHz has been allocated for TDD. To meet operators’ future requirements for ultra-wideband RRUs, ZTE developed the ZXSDR R8978 by using low consumption and broadband RF technologies. Supporting up to five carrier frequencies, the ZXSDR R8978 fulfills operators’ power-consumption requirements in large-capacity and large-coverage conditions. Its advanced efficient amplifier technologies include Crest Factor Reduction (CFR), Digital Pre-Distortion (DPD), Doherty, amplifier voltage adjustment, and time slot–based intelligent electricity conservation, dramatically reducing power consumption. The RRU uses noiseless natural heat dissipation, and can achieve a 35% reduction in power consumption compared with RRUs that use traditional air-conditioner heat dissipation, lowering electricity costs.

ZTE has a consistent track record of leading the global industry in innovations on TDD. In 2007, ZTE launched the industry’s first BBU + RRU base station architecture in an innovation that has now become the mainstream architecture of wireless base stations. In Beijing in February 2013, ZTE took the lead in achieving F + D cross-band Carrier Aggregation (CA) with on-site test rates reaching 430 Mbps (in 4 × 4 MIMO mode) and 223 Mbps (in 2 × 2 MIMO mode). Together with advanced LTE-A technologies such as CA, the ultra-wideband base station will further increase the competitiveness of LTE operators.

As of June 2013, ZTE has built TD-LTE pilot and commercial networks for 48 world-leading operators in 33 countries, spanning Europe, Asia-Pacific, Southeast Asia and CIS countries.
