"Three networks", that is, telecommunication networks (the main business is **, but there are also other services, such as fax and data bearing services, etc.), cable television networks (that is, one-way transmission of television programs network) and computer networks (mainly a large number of local area networks through the router wide area interconnection to form the Internet).
At present, telecommunications, cable television networks and computer networks are all large in size, but the technologies they use are also so different that it seems unlikely that one network will replace them in the short term. At present, these three networks are gradually evolving, and they are trying to make themselves have the advantages of other networks, forming a trend of "triple play integration". The so-called "triple play" refers to the technical penetration of the three networks, which can be interconnected at the network layer and use the same protocol at the application layer, but their operation and management are still carried out separately.
3G is the abbreviation of the third generation of mobile communication technology (English: 3rd-generation), which refers to the cellular mobile communication technology that supports high-speed data transmission. 3G services are capable of transmitting both voice (calls) and data (e-mail, instant messaging, etc.) at the same time.
The representative feature is the provision of high-speed data services.

Triple play integration is a generalized, social statement, at this stage it does not mean the physical integration of the three major networks of telecommunications network, computer network and cable television network, but mainly refers to the integration of high-level business applications.
The integration of high-level business applications is manifested in the fact that the technology tends to be consistent, the network layer can realize interconnection and interconnection, form seamless coverage, the business layer penetrates and crosses with each other, and the application layer tends to use the IP protocol of the first line of the unified shed, and gradually converges with the same goal of providing diversified, diversified and personalized services, and finally forms a set of operation and maintenance models compatible with multiple services in the network through different security protocols.
Simply put, the "three networks" is to realize the integration of cable television, telecommunications and computer communications, with the aim of building a sound and efficient communication network to meet the needs of social development. The integration of the three networks has high requirements for the application and practice of technology, and it is also necessary to realize the interconnection of various network layers in the actual construction process.
The integration of three networks is widely used, covering many fields such as intelligent transportation, environmental protection, first-class work, public safety, and Pingqin Bei'an Home. In the future, mobile phones can watch TV and surf the Internet, TV can make phone calls and surf the Internet, and computers can also play ** and watch TV. The three intersect with each other, forming a pattern of you having me and I having you.
You have too many questions, one by one, one, whether you can use 3G has nothing to do with your **, it has something to do with your mobile phone card and mobile phone. Your mobile phone is Unicom to support 3G,**The card must be Unicom and support 3G,You call customer service to ask if your card can be on 3G. >>>More
It is mainly reflected in the network. However, the network speed is dozens of times faster than the current GPRS. Since the current 3G standard in China is TD-SCDMA and the foreign system is WCDMA, for the time being, foreign 3G machines cannot enjoy 3G services in China. >>>More
1. Whether the automatic upgrade should depend on whether your network card hardware supports EVDO, if the network card hardware does not support it, there is no difference between it and the present after the upgrade, and it has nothing to do with the network card number you use, if you want to use it, you should change the hardware. >>>More
China Unicom 2G subscribers with 13X numbers apply to order 3G** through the online business hall to become 3G subscribers. **After the original **tariff becomes invalid, the 3G** tariff is used directly, which is no different from the ordinary 3G**. >>>More
