At present Intelligent mobile phone In the case of crazy competition of configuration and functions, people may not care so much about cluster intercom phones with GoTa technology. Such a functional mobile phone aimed at niche markets can give full play to its advantages at special times. Because GoTa has the characteristics of fast connection, full channel sharing, and single group members are not limited under a single load fan, it is very suitable for communication and scheduling in emergencies, especially in the face of inevitable natural disasters.

At 8:02 on the morning of April 20, a magnitude 7 earthquake occurred in Lushan County, Ya'an City, Sichuan Province. China's major communication enterprises immediately launched financial, material and human rescue operations in the disaster area. ZTE Thousands of GoTa finished mobile phones with cluster scheduling function were sent to the disaster area. For people outside the industry, GoTa may not understand it.

GoTa (Global open Trunking architecture) technology is a mobile communication system used for group dispatching and commanding communication, which is mainly used in professional mobile communication field. Different from ordinary mobile communication, the biggest feature of trunking communication is that the voice communication uses the PTT (PushTalk) button to connect in a push to talk manner. The called can be answered without off hook, and the connection speed is fast, and it can support group calls and other functions. It has been proved by technical practice before, TDMA technology It is the best choice for digital trunking. The existing digital trunking systems in the industry, such as Tetra and iDEN, are all based on TDMA technology. However, the domestic GT800, which has fully owned China's independent intellectual property rights, creatively combines TDMA and TD-SCDMA technologies, bringing the development of China's digital trunking to a new stage.

GoTa is a digital intercom technology. Compared with the traditional analog intercom products on the market at present, its grouping, confidentiality and voice clarity have been greatly improved, and it has the advantage of unlimited distance (under the coverage of network signals). The cluster communication function is also very powerful, which can simultaneously achieve intercom, command, positioning and other functions. Compared with some third-party software intercom products on the Internet, the GoTa function has the advantage of specialization. Recording, transmission and playback are carried out at the same time. One can listen to one click, and the other can hear the speech at the same time. Most of these third-party software intercom products are recorded first, then transmitted, and then broadcast. In addition, it also has GPS full-time positioning function, which can provide GPS navigation Background positioning and journey track playback will not conflict with cluster business, and can meet the application needs of special industries. In addition, users can build their own servers without relying on operators, so that the security is more guaranteed.

In addition, the design of GoTa digital trunking mobile phone fully considers the harsh use environment and unconventional use methods, and adopts waterproof, dustproof and shockproof Three prevention design , which greatly increases the use intensity of the mobile phone, and also makes anti-skid treatment on the mobile phone structure, so that the GoTa mobile phone can be used all day long, truly meeting the needs of professional cluster users.

Because of the above advantages, the group intercom mobile phone with GoTa function can dispatch the disaster relief personnel and convey information in a timely manner when local power, communication and other aspects have been severely damaged after some natural disasters, so as to ensure the smooth progress of disaster relief operations!
