Each Huaptec booster comes in a kit with 2 antennas and cables. It’s not advisable to change antennas or cable length in the kit, as accessories thoroughly correspond to the booster power. You can add antennas or splitters to extend a coverage zone of your booster (applicable only to powerful models). See Accessory/antenna page to choose extra stuff for your repeater.   

A booster is a device that is manufactured for consumer needs. The word repeater has a broader sense; this device is used for industrial purposes. But nowadays there is no deference between these words. So they can be used in the same context. Moreover, there are such expressions as mobile signal amplifier, extender or enhancer. They all mean the same as mobile signal booster and repeater.

Make a purchase in our online shop is extremely easy. First choose a product you’d like to buy, then click on “Add to Cart” button and make a payment.

LCD8/LCD9:"dBm" and "dB", unit of  power and gain. When the LCD8 is light, the LCD9 will be off;  when the LCD8 is off, the LCD9 will be light.

LCD10/LCD11:"Gain" and "Pout". "Pout" means output power. Light LCD10 means that LCD7 displays the gain of booster; light LCD11 means that LCD7 displays the output power of booster.

Sure, you can make a return within 30 days after you receive a booster kit. We can change the booster for another one or give your money back according to our moneyback policy. Please, visit Huaptec Policy to know more about our conditions.

The "SET" is reserved debug port. It will be used to debug the booster in future, but the debug software is not available now. It is supposed to be developed in future.

Sure, you can. You can change the booster within the period of 30 days after you receive a kit. We kindly ask you to contact us before you decide to make a replacement. Please, go to Huaptec Policy page to know what our policy regarding booster replacement is.

To start explanation, let’s figure out what uplink and downlink mean. Downlink in mobile communication means the following: signal from base station goes to mobile phone. Uplink in mobile communication means that signal from mobile phone goes to base station.

A cellphone, being a small portable device with small limited power battery, can’t afford transmission at high power. The matter is that with higher frequency comes more of signal loss, thus more power is required for transmission that is considered reliable. Mobile phones can’t compensate this loss as they can’t afford to transmit at high power. This is why cellphones have to transmit at lower frequencies as they let to have lesser free space loss. Therefore uplink frequencies (from phone to base) are lower than downlink ones (from base to phone).

You can easily install a mobile signal booster on your own. Installation is performed in 4 simple steps:

1) Fix an outdoor antenna in the point with good signal reception outside the house.

2) Mount the booster and an indoor antenna in the centerof the house or other area with poor signal.

3) Connect the antennas and the booster with cables.

4) Plug in the booster and enjoy strong cellular coverage!

For more information, please, download a manual on any product page or contact our Technical Support.

Communication signal exchange goes the following way:

Cell Tower>>Donor antenna>>Repeater Outdoor downlink (amplifies signals)>>Sever antenna>> Mobile phone (receives signal after amplification). After it communication goes in reverse order: the phone (transmits signal)>>Sever antenna>>Repeater indoor uplink>>Donor antenna>>Cell Tower.

To put it shortly, the signal goes in two directions: to phone and from it.

Each mobile provider transmits voice and 3G/4G signals at certain frequencies. To be sure the chosen booster will work correctly, check if device frequency/ies corresponds to those ones of your provider. Use our Booster Finder to know it or contact your provider directly. You’re welcome to write or call to our Support Service to get a professional consultation about this question. 

Each booster improves one or a few networks. It can be GSM/EGSM, DCS, 3G and 4G. GSM booster amplifies only voice, EDGE and GPRS, while 3G repeater is used to boost 3G mobile Internet on any device. Huaptec also offers dualband models which provide signal enhancement both of GSM and 3G, i.e. calls and 3G data.

Normally Huaptec booster system supports up to 220 phones within one area. The better the signal, the more it can support. The quantity of phones also depends on the resource conditions of the mobile operator.

As soon as you finish the installation and plug the booster into a power supply, you will see LEDs light up (the number and color of LEDS depend on the model).  It means the booster has been mounted correctly and it has started amplifying mobile signals all over the area. You can also check it with your mobile phone. If a number of bars shown on the screen has increased and you can freely accept and make calls, the system is functioning well.

Try to take the following measures:

1) Check that the equipment is on and is working properly.

2) Make sure that in the place where outdoor antenna is fixed, there’re at least 2-3 signal bars. If there’s no signal, change the antenna position.

3) Check if there is no self-oscillation. Heavy cell tower interference will make booster shut down automatically. In this case you will need to adjust antennas’ position and enlarge distance between them (at least 5 m).

4) Check the connections between the antennas/booster and the cable to see if they arenot loose.

5) Check if the booster is powerful enough for the area you’d like to cover. Mind that thick walls and stairs can be serious obstacles for a signal. 

If the signal is still weak, please call or write an e-mail to our support service.

Normally, the booster’s coverage is based on the outdoor signal. The better signal strength you get outside, the bigger coverage range you can get inside. Try placing the outdoor antenna into a location with better signal reception or, please, call our Technical Experts for more assistance.

Possible reasons may be:

1) The outdoor and indoor antennas are too close to each other.

2) The temperature of the equipment is too high, possibly due to sunlight.

3) The connection between the cable and equipment is loose.

4) The system has burnt because of the lightning or voltage surge.

If our recommendations don’t work, please, contact our Support Service for more assistance.

All Huaptec products got CE and RoHS approvals which guarantee that the equipment doesn’t contain any hazardous substances. Moreover, mobile phones emit heavily when coverage is poor. After installation of the booster signal will grow up to the maximum and electromagnetic emissions from mobile devices will reduce by up to 60 times.      

Check that the distance between the outdoor and indoor antennas is at least 5 meters. If the distance is less, change their location. If the problem is still not resolved, please, contact our Support Service for assistance.

To choose a correct booster model for you, determine the area you need to cover (sq.m.) and network you need to improve: voice, 3G/4G data or both. Use our Booster Finder on the home page to be sure you make the right choice. You can also get a ready-made booster solution for a certain area from 1 to 12 and more rooms or a vehicle.    

Huaptec provides each and every client with absolutely transparent guarantees. For detailed information, visit our Shipping&Guarantees page.

Booster’s working principle is quite easy. An outdoor antenna receives a signal from a mobile base station and transmits it to a booster. The device amplifies the signal and spreads it all over the area with an indoor antenna. Booster works in a duplex mode, which means that it not only gets the signal from the mobile tower but upon receiving sends it back.   

No, they will not affect each other, as there is no interference even if they operate on the same frequencies

Huaptec is one of the leading booster manufacturers in the world. Most of the online stores are resellers, who cannot be responsible for the quality of the product they offer. We’re direct producers and sellers with our own workshops and service centers, so you can fully rely on efficiency of our mobile boosters. Moreover, all Huaptec products are CE and RoHS certified and comply with European and international safety and quality legislations.

No, radio signal has absolutely no relevance to boosters. They operate with the help of cables – external and internal ones. So signals run via cables
