WangJianZhou appeal got the response of the industry for more than two years, TD-LTE maturity, and to keep the industrialization development evolution industry insiders thinks generally, 2011-2012, LTE will large-scale deployment and the preliminary commercial. According to Research institutions to provide the data Research show, at present many operators worldwide have announced the LTE network deployment plans, most of which will be its formal commercial time schedule in the 2011-2012 years between.
And the global mainstream WCDMA, CDMA2000 than standard, moving in for TD license is not only the global only this one, and start later, mobile 3 G actually got off on the wrong foot. But in 4 G era, to move for, TD-LTE and FDD-LTE integration, TD standards will no longer alone, can and global mainstream "must have 4 G standard" as a whole.
At present, China mobile has set up a file in the Shanghai, Hangzhou, Nanjing and Guangzhou, Shenzhen, Xiamen, Beijing 7 urban construction TD-LTE scale test nets. In the end, including united core technology, hays, QUALCOMM, and mobile chip manufacturer T3G developed LTE mobile terminal product, will be on the move in August in seven cities in China-LTE trial network the TD commercial test.
"Mobile cell phone jammer internal actually has given up 3 G, concentrate on meet the 4 G, on the other hand, the mobile Internet is increasing investment" according to people familiar with internal move in.
At the end of June, apple COO Tim cook appeared in the mobile, then the message says, apple will move in a marriage, so as to further develop the Chinese market. With this, there are foreign analysts pointed out that, in the face of mobile 600 million users, apple is likely in the next time a year within China mobile provide iPhone. However, it also depends on whether apple would like to support China's own technical standards TD, but also don't expel apple in China mobile launched 4 G network, namely TD-LTE to further after the potential for co-operation.
In the age of 3 G mobile cell phone jammer, one side to layout mobile Internet, one side is lifted up 4 G standard, and necessary "early" into the 4 G era. Of the battle between mobile is to strengthen the supervision of the mobile data services, we will take more flexible and effective means, conquers the mobile Internet discourse.

Only after these three to five pieces of cell phone jammer pass the inspection
Comparison of electron beam welding and laser welding in automobile manufacturing, an electron beam welding principle, regardless of engine, gearbox and other parts of the production, or body manufacturing and assembly, welding processes are important means of processing. In addition to the traditional arc welding, resistance welding and other welding techniques are commonly used in modern automotive production process, the application of electron beam welding and laser welding as the representative of a new generation of welding technology more widely, and by virtue of the precision and efficiency characteristics such as automobile production enterprises to improve product quality, reduce production costs and increase the competitiveness of products of a powerful tool. Electron beam welding technology originated in the 1950s, 10 years after the laser was born, laser processing technology research and application is started immediately.
Laser welding of the aspect ratio is less than the electron beam welding, generally in less than 10:1 (in gear laser welding, the weld depth is generally 4 to 6 mm, therefore this aspect also more appropriate), not suitable for the large thickness welding of the workpiece; laser welding of aluminum alloy and other high-reflectivity materials welding, there are still some technical difficulties, and must pass with filler wire and other auxiliary means in order to achieve better welding effect. The development of electron beam technology is quite mature, high-power, ultra-high-power electron beam welding equipment development is quite fast, and already has considerable practical value. The laser technology by the low rate of energy conversion and other technical obstacles, the power of the laser welding can not be significantly improved. It is the feature of cell phone jammer with various powers.
At present, the utility of laser power can not exceed 10kW, higher power laser, very fast increase in the cost and practical value is still relatively low. In Europe and the United States, roughly equal the price of the same power (5kW) electron beam welding equipment and laser welding equipment, laser welding of high efficiency, flexibility (not vacuum chamber limit) and user-friendly features integrated into the production line, laser welding equipment in the automobile manufacturing growth rate is much higher than the electron beam welding equipment. In the country, due to the lag of R & D of high power laser (kW or more), the actual use of laser welding equipment basic dependence on imports. cell phone jammer has various wavelength, appearance and power.
