What do you know about cell phone signal identifiers?

What is the evolution of mobile phone signals?

With the development of science and technology, smartphones worldwide, mobile phone appear in our life, more is not strange to us, we every day in the use of mobile phones, mobile phone signal is needed to better work, how much do you know about cell phone signal? Do you know what the identifier for each frequency band is?

A lot of friends in the process of the use of mobile phones will encounter this problem, it is on the speeding car or train, said it's easy to become other 4 g signal identification, such as 2 g, 3 g, H, E, etc. Although we do "deal with" the mobile phone every day, we do not understand the meaning of the signal, so what does it mean to say that it is similar to 2G, 3G, 4G, H, E, 4G +?

The mobile phone has been developed so far that it has produced four generations of mobile communication systems, namely 1G, 2G, 3G and 4G respectively. The signal signatures of each generation of communication systems are different. What is the communication system for each generation of mobile communication systems? The 1G is the first generation of mobile communication systems that can only be used to make phone calls without signal identification. 2G is the common GSM network, 2.5G increases GPRS or CDMA on GSM basis, 2.75G is the network of EDGE network based on GSM network.

3G is the three types of td-scdma, CDMA2000, WCDMA, 3.5g and 3.75g, which are the network of HSPDA on the basis of 3G. 4G/LTE is the technology that includes td-lte and fdd-lte, which are technically only 3.9 gigabytes, despite being touted as 4G wireless standards.

So to sum up, the meaning of 2G, 3G, 4G, H, E, 4G+ is becoming more and more clear.

G, on behalf of the mobile phone is 2G network, G refers to GPRS(2.5G network).

E, on behalf of the cell phone, is the 2.75G network.

H, on behalf of the cell phone, is the HSPDA network, which moves 3.5 G.

H +, on behalf of the cell phone, is the HSPDA network that moves 3.75 G.

4G/LTE, on behalf of the phone, is 4G.

4G +, on behalf of the phone, is 4G+ network.

In the current world of 4g penetration, users are increasingly unable to tolerate the speed of other Internet environments, such as high-speed trains, which may not connect to the Internet because of E's logo. So what is their Internet speed?

The speed of the network from slow to fast is G, E, 3G, H, H +, 4G/LTE, 4G +.

With the development of smart phones, expansion of 4 g signal also faster mobile signal network has brought people's lives better experience, let them in the busy work have a better network entertainment on mobile phones. Man of great self-control can distinguish good work and entertainment, but once some people play on the phone, and without restraint, immersed in the virtual world of the mobile phone, do their own things, which affects the efficiency of the work, in life, even their excessive use of mobile phones, used in the communication with family members and get very little time to relax and it to their family and a healthy body is very bad behavior. In some companies, they in order to control the excessive use of mobile phones, during the working hours, they open the cell phone frequency jammer, only allows a company internal network communication, to improve employee's work efficiency and the meeting is not interrupted by has important significance.

Understand the identifier of the mobile phone signal, are you more understanding of the use of mobile phones, if you don't know what kind of mobile phone signal need what kind of cell phone jammers, you can choose to buy a variety of frequency jammer, it can block a variety of signal. I'm sure you need a signal jammer in your heart.
