Kingtone Mobile Signal Repeater/Booster/Amplifier is a top of the line product that supports frequency bands (B20 800 & B3 1800 ). The adjustable controls all you to change your signal preferences for smoother voice and data transmissions. Experience improved signal strength regardless of your phone’s present coverage strength or frequency band!
Before buying please note!
1. Make sure the frequency band of your carrier is suitable for this item. Otherwise the device can’t work for you. If you do not so clear the frequency of your phone, you would click this link
www.frequencycheck.com for check the frequency band of your carriers.
2. Make sure you can receive good signal that you want to amplify on your house outside. Which must be can getting 3~5 bar signal (-70dB~90dB signal strength) on your mobile phone. Please note that the signal booster can only boost the mobile phone network signal, but it does not help to generate any signal. For example, if your outside signal has 0 bar, it can’t work or bring you any signal. Below is the method of check the mobile phone signal strength.
Applications
To expand signal coverage of fill signal blind area where signal is weak
or unavailable.
Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.
Indoor: Hotels, Exhibition Centers, Basements, Shopping
Malls, Offices, Packing Lots etc.
