ZTE : 2+4 solution drives new trend for private wireless network technologies

20 May 2015, Shenzhen, China - ZTE Corporation (0763.HK / 000063.SZ), a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, has launched the first globally available 2+4 solution at Critical Communication s World (CCW) 2015, held in Barcelona, Spain . The new product enables mission-critical communications in the private wireless and emergency communications fields, providing better services for industry users.

ZTE's 2+4 solution allows users to choose the scale of network construction as needed, ensuring reliable communications at reasonable capital expenditure (CAPEX) and guaranteeing long-term development. T he solution is based on ZTE's industry-leading software-defined radio (SDR) platform and provides unified network topology and maintenance, reducing manpower and maintenance costs.

T he 2+4 solution not only connects 2G and 4G networks, but provides voice, messaging, digital trunking, positioning, data collection, information query, image and video transmission, industry application, and other services in a single network through a unified system and hardware platform. By providing unified user management and trunk ing dispatching functions, the 2+4 solution allows for flexible configuration and dynamic dispatching between 2G and 4G groups , and allows dispatching agents to quickly and easily connect individuals and groups to respond to various dispatching and emergency command requirements.

SDR-based base stations have the following advantages over existing systems in the private network market:

- The devices are highly integrated for rapid deployment within small floor spaces, which speeds up installation by 30-50 percent.

- Radio F requency (RF) units can be installed outdoors on the tower, reducing feeder loss and increasing coverage one fold.

- RF units have a high power amplifier efficiency (> 40 percent), and its natural cooling capabilities can reduce electricity use by 80 percent.

- Analogue, 2G, 3G, and 4G systems share a hardware platform for software upgrading and smooth evolution.

SDR-based systems and radio base stations can not only provide digital trunking and broadband data services, but are also compatible with existing analogue terminals. In addition, these systems and base stations can smoothly evolve into 4G systems, protecting customers' existing and future investments.

Mr. Sun Mingliang, vice president of ZTE Trunking, said, "The 2+4 solution is a bridge to seamlessly integrate broadband and narrowband networks, and is a true user-oriented technological innovation. ZTE's products have been deployed on a large scale in the telecoms industry, as well as other sectors including government, public security, rail transit, energy, and other fields. In 2015, driven by customer demands, ZTE will introduce leading technology platforms and system architecture into the trunking industry, striving to ensure developments in key areas such as industry standards, information security, and product reliability, to provide more industrial applications and services, and promote the rapid development of the trunking industry."

At CCW 2015, which is attended by more than 130 leading equipment vendors and solution providers worldwide, ZTE also launched its compact portal communication devices -which can be widely used for on-site emergency communications and command in case of disasters and incidents - and communications solutions for government, transport, utilities, energy and other sectors. In addition, the company launched its ZiLTE private wireless communications solution for the rail industry, which supports closed circuit television (CCTV), passenger information systems (PIS), and trunk ing radio systems. The solution meets communications-based train control (CBTC) requirements and has already been used for the Hangzhou Metro and Wenzhou Rail Transit. ZTE also unveiled three narrowband terminals (the PH790, PH500, and PH520) at CCW 2015, which meet high design standards and provide unparalleled security and voice quality.
