Mentioned band cell phonesupports, the first is essentially a rigid band should be a clear division, which was mainly due to the limited frequency resources lead, present, China mainly by the Ministry of Information Industry is responsible for related matters. China?s mobile cell phonefrequency bands are commonly used in CDMA phones occupied CDMA1X, 800MHZ band; GSM mobile cell phonefrequency band occupied by 900/1800/1900MHZ; nearly two years of GSM1X occupied 900/1800MHZ dual band; 3G 900/1800/1900 occupied / 2100MHz band. GSM frequency bands: GSM mobile cell phonein China is mainly occupied band 900MHZ and 1800MHZ. The worker ofcell phone jammershould be trained to the specific technician ofcell phone jammer.
Essentially 1800MHZ also because the surge in the number of mobile cell phoneusers, resulting in a mobile communication network system is in overload state, which eventually led to the cell phonecommunication is prone to like dropped calls, crosstalk, poor voice quality, difficult to access, such as failure the phenomenon. To address these symptoms, more and more mobile cell phoneoperators and manufacturers are beginning to realize the urgency to solve this problem, and continue to take relevant measures to further expansion of mobile networks, so GSM1800Mhz have come into being, and has been called as DCS1800 (Digital Cellular System), it appears that based on GSM900, 1800?s dual-band network a reality. The company has made the production plan ofcell phone jammer.
Use GSM900/GSM1800 dual-band phone, users can switch between GSM900 and GSM1800 can be effectively avoided in the past dropped calls, poor call quality issues and difficult than previously to use only GSM900 network calls more convenient. In order to further expand the mobile network system capacity and improve the quality of mobile voice communications, recently launched in the market, a ?tri-band phone.? So-called ?tri-band? is consists of three operating frequency, three frequency is GSM900Mhz, DCS1800Mhz and PCS1900Mhz, and so on, so-called ?tri-band mobile phone? refers to the cell phonecan receive GSM900M, DCS1800Mhz and PCS1900Mhz three frequency band signals, from which to choose, which band signal strength, on the choice of which base station the signal. The future plan ofcell phone jammercompany has been approved by the general manager.
If one then blocked, free to do a band signal. It actually is to expand the mobile cell phonetermination rates. Mobile cell phoneusers are concentrated in some areas, especially the right to use tri-band cell phonetri-band cell phonebecause the flexibility in the GSM900, DCS1800 and PCS1900 switch between, so always call constantly and call quality. PCS1900 trillion network in North America (U.S., Canada) and the field of European countries, the widespread use of the communications network segment. As the tri-band cell phonewill work simultaneously at three different frequencies among the segments, so the tri-band mobile cell phoneis undoubtedly the three network characteristics. The production task ofcell phone jammerwill be finished according to the production plan of the company.
From a technical point of view, GSM1800 because of the high frequency band, making the signal penetration ability, so the tall buildings of the complex environment can bring good call quality and communication coverage; and PCS1900 channels in North America (U.S., Canada) and Europe has good communication skills, which no doubt for those who frequently travel between intercontinental provide the services they need. For operators, the three-band network to build, is completely alleviated the GSM900 frequency and capacity of the existence of the problem, making the network was further optimized, the peak traffic hot spots to be effective mitigation, termination rates higher, so that business is greatly improved. The expert has analyzed the prospect of cell phone jammer.
