The new GPS cell phone jammer is against the tracking device
CDMA is the abbreviation of (CodeDivision MultipleAccess), translated as Code Division Multiple Access, is a technology developed on the basis of digital communication technology branch of the
spread spectrum communication. The so-called spread spectrum, it simply is spread spectrum. CDMA technology uses a direct sequence spread spectrum is to use the carrier with the noise
characteristics than simple point to a much wider frequency band of a few communications the bandwidth required to transmit the same data, so that information can be high-speed transmission. The
advantages of CDMA include: CDMA voice coding techniques can dialogue surrounding environment noise reduction, clearer calls, CDMA uses spread-spectrum communication technology. The employee
management of the cell phone jammer company is also an important subject.
Thus can reduce the interference between the cell phone and can increase the capacity of the user, and the power of the cell phone could have done relatively low, so that the use of longer, CDMA
bandwidth scalability, you can also transfer images, and safety performance , CDMA, not only a good authentication system, but also because its transmission characteristics, using code division
multiple access, to prevent the ability to hear was stolen greatly enhanced. PHS Chinese called "low-power cell phones," the English name of the whole called Personal Handy,-cell phone the System
", is Japan's self-developed digital wireless telecell phone system. Its transmit power is much lower than the normal GSM cell phone is ideal for frequent the downtown area, provides the same
features as the GSM system. The new GPS cell phone jammer is against the tracking device.
Domestic PHS mostly using this system. WAP (Wireless Application the Protocol) Wireless Application Protocol is an open standard protocol, the use of it can send information on the network to the
cell phone or other wireless communication terminals. WAP is developed by the communications giant Ericsson (ERICSSON,), Nokia (NOKIA), Motorola (MOTOROLA) was established in 1997, Wireless
Application Protocol Forum (WAP Forum). It uses similar to the HTML markup language WML (Wireless Markup Language), and direct access to the general web and through WAP Gateway. The classification
of cell phone jammer is completed as per the emission power of cell phone jammer .
