Introduction to 4G antennas

Intelligent and multimedia trends are significant

   The 4G antenna network can provide rich multimedia transactions and download transactions. Therefore, for 4G antenna terminals, it needs to be equipped with a larger, clearer and more realistic display for 3D display, so that users can appreciate mobile very well. Multimedia services should be equipped with higher-pixel cameras to take more clear images to enhance the image's sensory effect; to supply more storage space, to save more images and audio and video files downloaded. In general, the 4G antenna transaction featuring the powerful data transaction function will be increasingly demanding for its terminal. The 4G antenna will truly fulfill the expected transaction, and the development of the 4G antenna terminal will always become the 4G antenna development stage. One of the important topics.

Single mode, dual mode and multimode terminals coexist

    A variety of 4G antenna skill systems coexist and the third generation of mobile communication is in the early stage. The second generation mobile communication will not exit the real situation in the market in a short period of time. It is decided that the future mobile terminals will be single-mode, dual-mode and multi-mode terminals. The situation of coexistence. At present, there are GSM/WCDMA, GSM/cdma2000, cdma2000 1X/1X EV-D0 dual-mode terminals in the mall; followed by the commercialization of TD-SCDMA specifications, dual-mode mobile phones or multi-modes supporting TD-SCDMA networks and other networks in the future. The phone may also be presented. The function request of the 4G antenna terminal continuously improves the skill characteristics of the 4G antenna, and the 4G antenna network can provide a more intelligent, diversified and personalized mobile transaction, which requests the function of the 4G antenna mobile terminal to be increasingly enhanced. Not only support existing voice transactions, SMS transactions, narrow-band data transactions, etc., but also support broadband communication services represented by multimedia transactions and high-speed data transactions.

Can be roughly divided into four categories

(1) Inter-business, including VoIP, mobile banking, videophone and video conferencing;

(2) Peer-to-peer transactions, including multimedia messaging, email, WEB, long-distance hospitals, etc.

(3) One-way information services, including digital newspapers, book publishing, long distance education, video shopping, mobile audio players, mobile video players, video on demand and karaoke;

Multicast services, including information delivery, GPS car navigation, mobile radio and mobile TV.

It can be seen that the 4G antenna not only brings new interpersonal communication methods such as videophone, multimedia messaging and e-mail to mobile phones, but also enables mobile phones to have mass media such as mobile TV, digital newspapers, books and information delivery. The function.
