If taking this method, power supply adapter of cell phone jammer will be interfered by the strong magnetic field of host of cell phone jammer .The frame rate can also be adjusted, and is proportional to the amount of data. The frame rate is the main parameters of the continuous effect of the screen. The brothers make a movie, please note that pull. AVI file audio portion of a wav audio formats. AVI file structure is not only to solve the synchronization of audio and video, and has the characteristics of the generic and open. Programming tool for VB, VC provides the most direct support, he can work in any Windows environment, but also the expansion of the function of the environment. The user can develop your own AVI video file, to call at any time in the windows environment. AVI itself open support of many coding technology R & D providers, different encoding makes AVI constantly improve many coding technology R & D providers to support a different encoding makes AVI continually improve.
24.4% of the users as to buy 3G handsets. 58% of users willing to participate in the organization of the operators stored calls-for-3G cell phone activities. Therefore, the CNNIC analysts pointed out that such operators to provide a more reasonable marketing strategy, will achieve a good effect on the market. In addition, the survey also showed that 54.4% of the users, the degree of attention to the cell phone is higher than the degree of attention to the operators. This cell phone is from the user's recent products, but also shows the carrier service now and do not cause too much difference. The pilot signal is a base station a continuous emission unmodulated direct sequence spread spectrum signal, it makes the cell phone able to get to the code division multiple access channel before the time limit, the correlation demodulation phase reference, and signal strength for each base station, decided to cell phone can determine when to switch.
Concentration four or more pilot signals in the CDMA mobile station activation (the pilot and the best guide frequency Ec / Io value difference is less than 6dB, and the than T_ADD threshold, but which does not have a The signal can be strong enough to become a true dominant frequency), in these regions, the other is not the mobile station to activate the sudden appearance of the concentration of a strong pilot signal generation leading to dropped calls mobile station in the handover process, the strong pilot signal as a potential sources of interference, which is the origin of the concept of pollution pilot. Ec / Io poor network signal level is good, that is in an area without a pilot of sufficient strength to the dominant cover, a few pilot strength considerable. Signal fast fading caused by frequent switching between different sectors of the business channel in the mobile station call, can easily result in dropped calls.
