ZTE Launches CDMA-Based Digital Trunking Technology

ZTE Corporation has launched its world-leading GoTa Digital Trunking Communication System–a CDMA-based new generation digital trunking technology for Chinese and international markets–in Beijing.

GoTa (Global open Trunking architecture) has been independently developed and launched by ZTE – the first time a Chinese enterprise has launched a digital trunking product that has an independent intellectual property right. The system has considerable benefits including wireless resource sharing technology and instantaneous connection to other users, preventing newly added trunking services having a negative impact on the traditional communications services and network resources.

Trunking communication is chiefly applied to the professional mobile communications field. Unlike conventional digital trunking systems, ZTE’s GoTa digital trunking mobile communications system makes use of CDMA technology to solve the key techniques in delivering trunking services. It allows large numbers of trunking users to share relatively fewer communication resources and dramatically improves the speed of call connection. The system gives fast access, much improved channel efficiency, enhanced privacy and the flexibility to expand the system as demand grows. ZTE has also launched its own commercial GoTa trunking terminals to promote the commercial use of the GoTa trunking system, and will continually roll out a series of terminal products including vehicle-mounted and professional terminals.

ZTE is already working with China Railways’ Communications Department, China Satellite Communication and other telecom carriers to work on related technical tests, intending to bring GoTa technology into national standards as soon as possible and meanwhile promoting the industrialization of China’s home-made trunking products.

The GoTa system is a mobile communications system for the dispatching of group users, which is chiefly applied in the private mobile communications field. The private mobile communications were developed from early point-to-point half-duplex mobile interphones to the present multi-channel and multi-BS trunking communications system, capable of providing voice and various non-voice services. The technology adopted was also evolved from the early analogue to the current digital. Unlike conventional mobile communications systems, trunking communications systems feature push-to-talk connection by pressing the PTT button. It provides fast connection and the called party can receive the call without the need of picking up the phone. Also, the system supports group call service.
