兼容性能更平滑:4G通信系统具备全球漫游、接口开放、能跟多种网络互联、

Compatibility smoother: 4G communication system includes a global roaming, open interfaces, various networking sorted, diversification, and a smooth transition from 2G terminal characteristics. <br><br><br><br>(4) to achieve higher quality multimedia communication: wireless multimedia communication services provided by the 4G communication including voice, data, image, etc., a large amount of information sent out via broadband channels, for 4G is also referred to as "Mobile Multimedia Communications" . <br><br><br><br>(5) communication costs are cheaper: 4G communication system can not only solve the compatibility issues with 3G, so that more of the existing communication users can easily upgrade to the 4G communications, and, 4G also introduces many cutting-edge communications technology, to implement much easier quickly. When the construction of 4G communications network systems, telecommunications operators are considered directly on 3G infrastructure communication network, the method introduced gradually, effectively reduce operating costs [3].

Compatibility is smoother: 4G communication systems have the characteristics of global roaming, open interface, connectivity with multiple networks, diversity of terminals and smooth transition from 2G.<br><br>(4) To achieve higher quality multimedia communication: 4G communication provides wireless multimedia communication services will include voice, data, video and so on, a large amount of information transmitted through the broadband channel, for which 4G is also known as "multimedia mobile communication."<br><br>(5) Communication costs are cheaper: 4G communication system can not only solve the compatibility problem with 3G, so that more existing communication users can easily upgrade to 4G communication, at the same time, 4G also introduced a lot of cutting-edge communication technology, it is much easier to achieve much faster. In the construction of 4G communication network system, communication operators consider directly on the infrastructure of 3G communication network, using a gradually introduced approach to effectively reduce operating costs.

More smooth compatibility: 4G communication system has the characteristics of global roaming, open interface, interconnection with various networks, terminal diversification and smooth transition from 2G.<br>(4) it can achieve higher quality multimedia communication: the wireless multimedia communication service provided by 4G communication will include voice, data, image, etc., and a large amount of information will be transmitted through the broadband channel, so 4G is also called "multimedia mobile communication".<br>(5) communication cost is cheaper: 4G communication system can not only solve the compatibility problem with 3G, but also enable more existing communication users to easily upgrade to 4G communication. At the same time, 4G also introduces many advanced communication technologies, which is much easier and faster to realize. In the construction of 4G communication network system, communication operators consider directly on the infrastructure of 3G communication network, and adopt the method of gradual introduction to effectively reduce the operation cost [3].<br>
