ZTE's 2+4 solution allows users to choose the scale of network construction as needed, ensuring reliable communications with reasonable capital expenditures (CAPEX) and guaranteeing long-term development. The solution is based on ZTE's market-leading software-defined radio (SDR) platform and provides unified network topology and maintenance, reducing labor and maintenance costs.
The 2+4 solution not only connects 2G and 4G networks, but also offers voice, messaging, digital trunking, positioning, data collection, information querying, video and image transmission, enterprise applications, and other services on a single network through a unified system and hardware platform. By providing unified user management and dispatch trunking capabilities, the 2+4 solution enables flexible configuration and dynamic dispatch between 2G and 4G groups, allowing dispatchers to quickly and easily connect individuals and groups to meet diverse dispatch and emergency command needs.
SDR base stations offer the following advantages over existing systems in the private network market:
- The devices are highly integrated for rapid deployment in small spaces, accelerating installation by 30-50 percent.
- Radio frequency (RF) units can be installed outdoors on the tower, reducing power loss and increasing coverage by a single fold.
- The RF units have high power amplifier efficiency (>40 percent), and their natural cooling capabilities can reduce electricity consumption by up to 80 percent.
- Analog, 2G, 3G, and 4G systems share a common hardware platform for software upgrades and easy evolution. SDR-based systems and radio base stations can not only provide digital broadband and trunking data services but are also compatible with existing analog terminals. Furthermore, these systems and base stations can seamlessly evolve into 4G systems, protecting customers' existing and future investments.
In addition, the company launched its ZilTE private wireless communications solution for the rail industry, which supports Passenger Information Systems (PIS), Closed-Circuit Television (CCTV), and radio trunking systems. The solution meets the requirements for Communications-Based Train Control (CBTC) and has already been deployed on the Hangzhou Metro and Wenzhou Rail Transit. ZTE also unveiled three narrowband terminals (PH790, PH500, and PH520) at CCW 2015, which meet high design standards and provide unparalleled security and voice quality.
