What do you need to learn to become a 3G engineer?

The skills that 3G engineers need to master must have a bachelor degree or above in communication and electronics, be familiar with the technical principles of mobile communication and microwave communication, be proficient in C or C++ programming, have rich experience in digital circuit design or hardware development, or have experience in mobile phone software and hardware development such as CDMA, GSM or TD-SCDMA, WCDMA, etc. The English foundation of communication technology specialty must be solid, otherwise it is difficult to master the deep-seated technology of this industry.

brief introduction

3G engineers include 3G wireless software development engineers, 3G wireless R&D quality engineers and 3G wireless network planning and optimization engineers. The rapidly developing mobile communication industry has higher standards and demands for talents. Lecheng 3G creative industry is the largest R&D base in China and the only 3G talent training institution designated by the Ministry of Industry and Information Technology. At present, it has established in-depth talent cooperation relations with 1280 3G mobile Internet enterprises, and trained 3G mobile phone software development engineers in strict accordance with the employment requirements of the cooperative enterprises. At present, nearly 1,000 3G mobile phone software development engineers have been sent to the 3G mobile Internet industry.

background knowledge

I. Concept

3G is the abbreviation of the third generation mobile communication technology (English: 3rd-generation), which refers to the cellular mobile communication technology supporting high-speed data transmission. 3G service can transmit voice (call) and data information (e-mail, instant message, etc.) simultaneously. ). The typical feature is to provide high-speed data services.

Second, the difference

Compared with the first generation analog mobile phone (1G) and the second generation digital mobile phone (2G) such as GSM and CDMA, the third generation mobile phone (3G) generally refers to a new generation mobile communication system combining wireless communication with multimedia communication such as the Internet.

The main difference between 3G and 2G is the speed of voice and data transmission. It can better realize global wireless roaming, handle images, music, video streams and other media forms, and provide various information services including web browsing, teleconference, e-commerce and so on. At the same time, we should also consider the good compatibility with the existing second-generation system. In order to provide this service, the wireless network must be able to support different data transmission speeds, that is, at least 2Mbps (megabits per second), 384kbps (kilobits per second) and 144kbps in indoor, outdoor and driving environments, respectively (this value will change according to the network environment).

job description

3G engineers are engineers engaged in 3G communication technology industry, including 3G wireless software development engineers, 3G wireless R&D quality engineers and 3G wireless network planning and optimization engineers.

quality requirements

Because 3G technology has very high requirements for senior mobile phone software and hardware development engineers, in general enterprises, 3G engineers must have bachelor degree or above in communication and electronics, be familiar with mobile communication principles and microwave communication technology, be proficient in C or C++ language programming, have rich experience in digital circuit design or hardware development, or have experience in mobile phone software and hardware development such as CDMA, GSM or TD-SCDMA, WCDMA, etc. Judging from the requirements of 3G for talents' quality, it seems that it is difficult for fresh graduates trained by colleges and universities to meet the requirements of the market. In fact, service companies related to the 3G industry are more inclined to recruit employees from the communication industry. However, this does not mean that recent graduates have no chance to enter 3G. Through the solid foundation laid by academic education, supplemented by vocational training, college students can still find their place in the fiercely competitive 3G workplace.

In September 2006, the Ministry of Information Industry began to carry out 3G professional qualification certification and training in the national communications industry. At present, there are not many training institutions engaged in this cutting-edge technology in China, and only a few institutions such as 3G DreamWorks in Wuhan can provide professional training courses for 3G engineers.
