2010 is considered to be the deployment year of long-term evolution by people in telecommunication field. The long-term evolution is the main 4G technology all over the world, which is developed by some magnates in this field and gaining support by many telecommunication device providers. People may always ask what the 4G technology is. 4G provides the service of high-speed network broadband, which is based on the long-term evolution standard.

High speed is one of the characteristics of the 4G. In theory, the download speed of long-term evolution can reach 100MB per second, which is equal to two thousand times of dial-up internet access. According to this speed, only six seconds are needed to download a document which is six hundred MB. However, the speed is twenty to forty MB per second, which is still three times of the 3G, because the speed is influenced by transmission distance and the population of users. 4G offers clearer network service, such as the online movie, online games and online video conference.

Since the cell phone was invented in the year of 1973, there have been 4.6 billion people using the cell phone. The cell phone is not only utilized to call somebody. After measuring the network all over the world, Ericsson declared in 2010: the data flow created by the user has surpassed the speech flow. According to the ABI research, the moving speech business has increased rapidly since 1992. The profit reaches 580 billion dollar in 2010. But the users will be saturated in the year of 2011. The data flow is becoming the new growth point of the operators. Going with the demand of broadband speed is the competitive need. for the companies who have a bottle-neck of the old technology mode, 4G will be the new direction. ãEUREUR

Users ties up the data business with their mobile service. In the conversion from 2G to 3G, the fee of 3G is higher than 2G obviously. The device will be cheaper, while the service will be more expensive, which is the tendency of the telecommunication industry. 4G brings people faster speed and great impact, and it will change the working and entertainment way of them. However, it will cost a lot to implement the change. The related integrated circuit is HMC572.
