About Boosters and MyAmplifiers
How does a cell phone repeater work?
A cell phone repeater is a bi-directional device that catches mobile signal from the nearest cellular tower and amplifies it to improve the quality of your mobile environment. This has the dual effect of improving your reception and of increasing the signal sent from your phone. The major purpose of using a cell phone repeater is to add another 2-3 bars to your usual mobile reception. For detailed information, please visit the How Cellular Amplifiers Work page.
How many mobiles and 3G connections can support a cell phone repeater at the same time?
The number of simultaneous subscribers is not limited. For example, according to our tests, an NS300GW can support over 100 people using their mobiles at the same time, within an area of 300m2, without any problems. The key factor is not to move out of the area of coverage.

How to check precise signal level in dB?
To interpret signal level with maximum precision, you’ll need to switch your cell phone into Field test mode (FTM). It’s an application available in free access or a phone mode requiring no extra setups for most popular mobile OS (operating systems). On most used mobile OS the test mode can be started as follows:
Note! To get parameters for 2G, 3G and LTE, disable WiFi. In case you cannot find Field Test Mode on your cell phone, contact us to get the solution.
How to aim outdoor directional antenna correctly?

How to interpret the results of signal testing in dB?
For maximum precision in signal level testing, switch your cell phone into Field Test Mode and see dB parameter. The closer dB signal level to 0, the better cell phone reception you’ll get.
