The technician is designing the drawing of cell phone jammer

By using "packet" technology, Internet users can disconnect from the pain (situations probably just use the download software NetAnts almost). In addition, the use of GPRS and WAP and the Internet in different ways, as with WAP Internet access at home, the first "dial-up connection", while the Internet can not be used after the phone line, but it is more advantageous GPRS, download data and calls can be the same time. Technically, the sound transmission (ie, calls) to continue to use GSM, and data transmission can use GPRS, so, put the mobile phone applications to a higher level. The remote control function of cell phone jammer is one of good characteristics.
And the development of GPRS technology is also very "economic" because only use the existing GSM network to develop to. GPRS wide range of uses, including through the phone to send and receive e-mail, Internet browsing. Band mobile phone that supports the first of these bands should be clearly divided essentially rigid, and this was mainly due to the limited frequency resources led to the current mainly by the Ministry of Information Industry of China is responsible for related matters. China's mobile phone frequency band used mainly CDMA1x, 800MHZ band; GSM mobile phone frequency band occupied by 900/1800/1900MHZ. Mobile phone type definition refers to the external type, now more commonly used classification is folded into a mobile phone (single-screen, dual), vertical, slide, rotary and other types of. The main control software is very important for cell phone jammer system.
Talk time literally can understand its meaning, that phone can be used to call time. Currently, we have seen mobile phone talk time and standby time is also just as test data, the actual talk time depending on network conditions, mobile phones and their batteries and other power factors. More precisely, said in a phone talk time of mobile phone batteries fully charged battery under the premise, and began to call the phone has been in contact up until the phone to automatically interrupt the contact time required. Longer talk time, that the smaller the power consumption of mobile phones, mobile phones, the stronger the ability to receive signals. Instead call the shorter the time, the greater the power that mobile phone the ability to receive signals worse. The indication light of cell phone jammer will show the status of cell phone jammer .
Impact of cell phone talk time of course the main factor is the cell phone battery and the use of the environment and the use of methods, such as if the battery is not sufficient, then the phone's talk time will certainly be reduced; phone talk time outdoors than indoors strong, because in Interior cell phone needs to consume a certain amount of power to penetrate walls or other masking material. Of course, if the call is active, open the phone's screen and backlight, the talk time will surely be the standard condition than in the talk time is short. Phone work in the waiting state called standby. Battery standby time is the mobile phone standby mode in continuous use. The staff member is determining the shielding position of cell phone jammer .
Can also be interpreted as a cell phone fully charged battery, without a call, do not shut down the standby mode, the battery has been consumed by its own low-battery warning to appear between the time that can be sustained. Standby current consumption is relatively small, almost nothing to do with the network, according to different models, the current consumption to a few tens of mA mA range. Standby time depends on battery capacity and the size of current mobile phone consumption. The standby time of algorithm: cell phone battery capacity / standby operating current = standby time. And the manufacturer's standby time is only a test data, the actual standby time will be affected by many factors, such as the battery capacity, the use of state phones, network signal strength and so on. The real time inquiry function is the important of cell phone jammer system.
