The effective shielding distance of cell phone jammer is 0-100m
Unicom launched, relying on the CDMA2000 1X network, and CDMA mobile phones to watch TV programs through the wireless data channel to transmit streaming media, China Mobile is based on the GPRS network. There are many differences in the different networks supported transmission rate and movement speed GPRS theoretical transfer rate of 115kps (actual is around 28KB), the CDMA1X theoretical rate of more than 180kbps (actually about 65kb), the two companies are using 3GPP standard format as video and audio encoding format. The third is the implementation of digital television broadcasting network, a mobile terminal on the installation of a digital TV receiver module.? cell phone jammer is also called? cell phone jammer .
Use of digital multimedia broadcasting (Digital Media Broadcast, DMB) technology, to directly receive digital TV signals through the digital TV broadcasting network, and the interactive nature of the business through the cellular mobile communication network. The typical technology has been formed in Europe, a relatively complete mobile TV standards and norms DVB-H (handheld digital video broadcasting). DVB-H high-speed burst mode to receive TV programs, and then proceed to buffer and play for a long time, can save the ability to consume. Currently, DVB-H trial network in Europe has been successfully opened, such as Berlin, Germany DMCO pan-European Instinct Project, the French TDF group and Helsinki, Finland FinPilop.? cell phone jammer can limit the use of the cell phone.
In addition, digital TV standards such as the Japanese ISDB-T (Integrated Services Digital Broadcasting ? Terrestrial transmission) and the U.S. ATSC in in for change. China?s Tsinghua University and Shanghai Jiaotong University were also in the digital TV standard DMB-T and ADTB-T on the basis of studies of domestic technology. The most promising mobile TV technology is through the integration of digital television and mobile phone. This way need to be installed on the mobile terminal a digital television receiver module, you can not through the mobile communication network link, direct access to digital television signals. The charm of the digital broadcasting is that it can high-speed transmission, high-bandwidth channel within the coverage area, the number of receive broadcast audience there is no limit.? cell phone jammer is the hidden type and not easy to be found.
Compared with the mobile cellular network using point-to-point connections, it can be more economical to provide our audience with a perfect quality audio-visual services. This technique is divided into T-DMB (Terrestrial Digital Multimedia Broadcasting) and DVB-H (handheld digital video broadcasting) in two forms. 2.3 Mobile TV mobile TV service in operation mode operating mode in accordance with the situation in China there are three operational modes, namely the separate operations of the telecom operators, radio and television operators separate operations and cooperation between the two operating mode. 2.3.1 The telecom operators telecom operators of a single mode of operation separate operations can be divided into two ways, one is the mobile operators will shift 4 fixed communication network technology as a downlink to provide users with mobile TV business.? cell phone jammer? is the typical machine for cell phone signal jamming.
