Learn more about American cell phone signals

According to the signal frequency band of the country, you choose to buy the right signal interference, buy signal jammer, know spectrum is very important, otherwise you will find that you would buy signal jammer to some signal doesn't work, so this is how important to you.
 
2G (icon display E): t-mobile's GSM network operates at 850 MHz and 1,900 MHz frequencies. A device can only use 850 megahertz or 1,900 MHZ, and it can still use t-mobile's domestic network.
 
3G (icon 3 g): t-mobile's UMTS network operating band iv, which USES a frequency of 1700 MHz and 2100 MHz. Specifically, t-mobile USES 1,700 MHz frequencies to send information to the community, and then receives information using the 2100 MHz frequency. A device must be able to use both frequencies to use t-mobile's domestic UMTS network.
 
4G (icon display H +): t-mobile's HSPA + network runs on the same band 3 g network, band iv, which USES 1700 MHz and 2100 MHz frequencies to transmit voice and data services. The 1700 MHz frequency sends information to the cell web site, and the 2,100 MHz frequency receives information.
T-mobile switches from EDGE to HSPA + in 1900 MHZ. This will allow the use of our 4G network using our 4G network on 1900 MHz.
 
4G LTE (real 4 g): t-mobile's 4 g LTE network will operate in the same band 4 g HSPA + network, with iv, it USES 1700 MHz and 2100 MHz frequencies to transmit data services.
4G LTE does not provide voice service, so the call will go back to our HSPA + network until voice end LTE(VoLTE) software is ready.
T-mobile's 4G LTE device will be the latest and newest operator.

There are all kinds of satellite navigation systems, such as compass, that can find their place within minutes. To avoid noise interference with these specific frequencies, change the frequency quickly.
 
The position of the weak from the original correct target's reflection and thus wrongly detecting the target of the strong signal is a spoofing signal, not a signal. A strong searchlight that harms radio waves. If you have strong interference with the same frequency range, GPS, in order to signal the interference with GPS radio waves, and use GPS interference analysis. Wireless interception will play an important role in getting rid of potentially dangerous situations.
 
There are some common things that are useful to people. It can help phone interference and GPS interference protect people's privacy. Before you buy, make clear that you want to interfere with the frequency of the signals you have, and you need to be able to select the appropriate directory by directly selecting the eavesdropper.
