TDD system for China Unicom just isn't dominant, although within the 3G era, which includes a substantial network, so China Unicom is planned ahead of the end of this year each of the cities in the nation to raise the speed to 42M, temporary investments in 4G network building will not boost an excessive amount of, save using the FDD's licence.
The current status quo for China Telecom's most disadvantaged, mainly because at present, none in the operators on the planet successfully implement seamless connection CDMA and TD-LTE, so Telecom can do is continue to dig 3G, await the coming of FDD's licence.
Based on the foregoing, the foreseeable period of five years, 4G will present a stage of speedy improvement. China Mobile will sting in the construction with the TDD is better than 4G of China Unicom, China Telecom developing. But China is equal to 4G.
Regardless of the 4G era has had an enormous effect on our mobile lives, on account of the speeds (mainly downlink rate is higher) upgrade, change some habits we may well also take place. But in the field of video surveillance transmission at present isn't mainstream applications. The purpose for this can be as follows:
1, 3G on December 31, 2008, the Chinese Government issued licences, and to this day has been establishing for just about 6 years, 4G construction belongs towards the early stages, to become in a position to achieve the same coverage because the 3G necessary for years;

Developing two, 4G only in some densely populated areas or urban building, rural coverage is extremely low, plus the County now, even 3G didn't reach hundred percent coverage;
3, 4G limited surveillance applications, which include in subway stations, because the Metro station underground, concrete is very thick, ground stations signals from incoming ground,Wireless Security Cameras equivalent to blocked signals and poor underground base station signals can cause the standard reception of signals. The other hand, in the sport of high speed, the terminal's ability to obtain signals weaken, so 4G inside the field of video surveillance in underground transport troubles.
4, 4G belonging to share the bandwidth data with commercial expertise variations can predict in the densely populated area to person user 10Mbps downlink bandwidth,Fish Eye Camera to attain HD monitor is not quick. North Green last August within the Usa, the 4G experiments inside the Usa greater signals can only transmit one channel of 720P.
five, 4G costs drastically larger, there is a piece on on the internet, "forgot to turn off the 4G, the Residence was owned by the move, move, modify your life. "Although absolutely nothing that poor,Pro-IP cameras but in accordance with 1G flow ten bucks if, 1 1080p image transmission for 25 minutes following use rough estimates to commit 25 bucks a hour visitors charges, and monitoring business goods at reduced costs, a lot more and more sensitive to cost, the present transport costs certainly will not match the current status of monitoring market.
