What is a 3g engineer?

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.

Introduction of 3G background knowledge

The concept of 3G

It 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.

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).

3G is the third generation communication network. At present, domestic networks other than GSM and CDMA are not supported. GSM devices use time division multiple access, while CDMA uses code division spread spectrum technology. Advanced power and voice activation can provide at least three times the capacity of GSM network. The industry regards CDMA technology as the mainstream technology of 3G, and ITU has determined three wireless interface standards: CDMA2000, WCDMA and TD-SCDMA, which means that domestic CDMA can smoothly transition to 3G network. The main features of 3G are. The first generation analog mobile phone (1995) can only make voice calls; From 1996 to 1997, the second-generation GSM, CDMA and other digital mobile phones (2G) have added the function of receiving data, such as receiving emails or web pages; In fact, 3G was not born in 2009. As early as 2007, 3G was produced abroad, and China also successfully developed China 3G in 2008. The theoretical peak downlink speed can reach 3.6Mbit/s (2.8Mbit/s), and the peak uplink speed can also reach 384 KBit/s, which can't be 2G per second as said on the Internet. Of course, the next movie can't be completed instantly. Note: G3 does not stand for 3G, but is the abbreviation of "Guide3". Guidance has two meanings: verbs represent guidance, influence and domination, and nouns represent guidance and guidance. Taken together, the general idea is to lead two other friends into the 3G era. "3" represents the convergence of mobile broadband fixed-line mobile TV in 3G era. A bolder guess is that China Mobile will go beyond the existing 3G concept, provide network support, terminals and services suitable for the above-mentioned converged services in the TD-LTE era, and lead people into real 3G life. So G3 is a very complicated concept. Unless China Mobile reneges on its mobile phone brand, there will be only one strategic brand, covering brand businesses such as GSM, Shenzhouxing and M-Zone.

China 3G Prospect Forecast

China is recognized as the largest 3G mobile market in the world, but there is a serious imbalance in 3G-related talents. There are less than 1000 professionals engaged in 3G application software development. According to the forecast of the Ministry of Industry and Information Technology, in 2065,438+00, the shortage of China's 3G talent market will exceed/kloc-0.0 million people, including about 500,000 3G software engineers.

With the shortage of 3G talents, 3G industry has become a new high-paying industry, and software developers based on 3G have become particularly sought after. Human resources experts say that 3G software development is one of the hottest and most popular occupations in the next few years. According to the salary report released by 55 1.com, the annual salary of a senior embedded software engineer with 10 working experience is about 300,000 yuan. Even the average monthly salary of junior embedded software developers is about 5,000 yuan, and the average monthly salary of senior embedded software engineers has exceeded 10,000 yuan. Moreover, with the further development of 3G applications, the salary of 3G software R&D talents will further increase!

At present, GSM and CDMA networks are used in China: GSM equipment adopts time division multiple access, CDMA adopts code division spread spectrum technology, and advanced power and voice activation can provide at least three times the capacity of GSM network. The industry regards CDMA technology as the mainstream technology of 3G, and ITU has determined three wireless interface standards, namely CDMA2000, WCDMA and TD-SCDMA. In other words, CDMA in China can smoothly transition to 3G network. The main feature of 3G is that it can provide mobile broadband multimedia services, including 144kbit/s in high-speed mobile environment, 384kbit/s in walking and slow mobile environment, and 2Mbit/s in indoor environment.

What qualities do you need?

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 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. Only a few institutions in Beijing, such as 3gdci Digital Content Institute, can provide professional 3G engineer training courses.

There is a shortage of 3G talents, with an average annual salary of more than 200,000.

The birth of 3G, a technical standard, greatly improved the data carrying capacity of mobile communication network, and also provided a more solid technical platform for the combination of mobile communication network and Internet. Under the 3G network, almost all services that can be realized on the Internet platform can run on the 3G network. In the 3G era, mobile value-added services are diversified. In addition to the original 2.5G services (such as SMS, MMS, ringtone download, games, WAP and IVR), various new value-added services (video on demand, high-speed Internet access, online games and industrial 3G applications, etc.). ) will be launched one after another, greatly enriching people's lives. After 3G enters the stage of large-scale construction, the demand gap will reach one million. At present, there are less than 10,000 3G core talents in China, and the market of only 10,000 people is said to have hundreds of billions of dollars. This shows the value of 3G talents. The insiders describe it this way: thousands of pets are in one, and 3G talents are waiting for the price. Facing the booming 3G industry, the demand gap of 3G talents has become an urgent problem, and traditional software talents have to face the crisis of knowledge structure renewal. Wang, deputy director of the talent exchange center of the Ministry of Industry and Information Technology, said that after 3G enters the stage of large-scale construction, if the training of 3G talents can't keep up with the requirements of industry development, it will greatly restrict the development of 3G industry.

According to analysis, the market scale of 3G mobile value-added services in China will reach 10 trillion, and the growth rate will be maintained at 50% or even higher in the future. Therefore, the mobile value-added market will urgently need a large number of mobile value-added software engineers. However, such talents are very rare in the current market. It is conservatively estimated that with the acceleration of large-scale construction and application of 3G projects, the market gap of mobile value-added software engineers will reach more than 500,000.

Human resources experts say that embedded software development is one of the hottest and most popular occupations in the next few years. According to the statistics of authoritative departments, at present, the talent gap of embedded software in China is about 200,000 people every year. In the future, with the continuous acceleration of "triple play" and the full deployment of 3G networks, this number will increase exponentially. It is hard to imagine what kind of crisis the embedded software industry will face in the future if this problem is not solved.

According to the published salary report, the annual salary of a senior embedded software engineer with 10 years working experience is about 300,000 yuan. Even the average monthly salary of junior embedded software developers is about 5,000 yuan, and the average monthly salary of senior embedded software engineers has exceeded 10,000 yuan.
