The development of smart phone is inseparable from the development of cell phone signal network. What is the development process of mobile phone signal?
We know that the development of science and technology is bound to bring about a new wave of scientific and technological upsurge. For all things, it is the process of replacing old things with new ones. New things are always more popular. But old things also have important characteristics. The evolution of cell phone signal is also gradually upgrading, and it is continuously improving on the network speed, and has the fastest 4G signal at present.The 5g signal is being developed by telecom operators and will be widely used in the next two years. At that time, 5G jammer will also enter the jammer market.

The emergence of cellular mobile communication is a revolution in mobile communication. Its frequency reuse, greatly improving the utilization rate of frequency and increase the system capacity, the intelligent network can realize the function the transfer and roaming, expand the scope of customer service, but the simulation system has four major faults: no public interface between each system; It is difficult to carry out data bearing business; Low spectrum utilization is not suitable for large capacity; Safety secrecy bad, easy to be eavesdropping, easy to do "fake" no public interface between systems in Europe, in particular, each other can't wander, caused great inconvenience to the customer, now has to be eliminated.

GSM digital mobile communication system originated in Europe as early as in 1982, Europe has several large analog cellular mobile system in operation, such as the Nordic nations NMT (mobile phone) and British TACS (total access communication system), and other countries in Western Europe also provide mobile business. When the system is a system that can't be used abroad in order to facilitate unified use mobile phones in Europe, need a public system, in 1982, the Nordic countries to CFPT (European executive convention of posts and telecommunications), submitted a proposal calling for a 900 MHZ band public European telecom business practices.GSM jammer for sale online is an instrument for interfering with this signal.

CDMA (Code Division Multiple Access) Code Division Multiple Access, the principle of the technology is based on the spread spectrum technology, the need to send a certain signal bandwidth information data, using a high-speed bandwidth than the signal bandwidth pseudorandom Code modulation, make original data signal bandwidth is extended, the carrier modulation and send out again. Receiving end use the exact same pseudo random code, and the bandwidth of the signal correlation processing, the broadband signal into the original data of narrow-band signals that the expansion, in order to realize information communication so it has good anti-interference, anti-multipath fading, confidential security high, with frequency can be in multiple reuse in the district, the capacity and quality can make trade-offs between attributes such as these properties make CDMA has a great advantage than other systems, more advanced than GSM, therefore, also known as 2.5 G.

The fourth-generation mobile telephony standard refers to the fourth generation of mobile communication technology, which is abbreviated as 4G. The technology includes td-lte, fdd-lte, and fdd-lte, which is, in the strictest sense, that the LTE is only a 3.9 G, although it's advertised as 4G, but it's actually not recognized by the 3GPP as the next generation of wireless standard imt-advanced for the international telecommunication union, so it's technically not even 4G yet.

The fifth generation mobile phone operation communication standard, also known as the fifth generation mobile communication technology, foreign language abbreviation: 5G. It's also an extension of 4G, which is being studied. There is no public specification or official document of any telecommunications company or standard organization (such as 3GPP, WiMAX BBS and itu-r) mentioned in the official document. 5 g network, the future will faces the challenge of network deployment, operation and maintenance, this is mainly due to the network there are all kinds of wireless access technology, and network node coverage each are not identical, the relationship between them is very complicated. Therefore, the intelligence of self-organizing network (SON) will become an indispensable key technology of 5G network.
