How do I boost my cell phone signal?

Dropped calls and slow data rates are generally caused by distance from a cell tower or natural and man-made obstructions, such as buildings, hills, trees, etc...

Cellular signals of cell phones and data cards can be boosted by the combination of a high gain antenna and bidirectional cell phone booster and 4A TECHNOLOGIES offers multiple solutions to stay connected.

There are two steps to ensure a reliable cellular communication. The first step is receiving a strong signal. 4A TECHNOLOGIES’s high gain antennas collect weak or distant cellular signals and send them to the cell phone booster. The cell phone booster then boosts those signals and rebroadcasts them to the cell phones and data cards falling within the range of cell phone booster

The second step is transmitting the signal back to the cell phone tower which is typically the weakest part of a phone’s ability when signals are weak. With a 4A TECHNOLOGIES bidirectional cell phone booster you are able to broadcast a much stronger signal back to the cell phone tower. A high quality 4A TECHNOLOGIES cell phone booster is critical for maintaining a constant connection between the cell phone and cell phone tower.

All 4A TECHNOLOGIES cell phone boosters have Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.

All 4A TECHNOLOGIES cell phone boosters have auto shut off function available for both uplink and downlink to avoid deep self-oscillations from jamming the towers.

4A TECHNOLOGIES offers a wide range of powerful mobile wireless and building cell phone boosters for all carrier frequencies as well as high-gain antennas with multiple mounting options.

What is a basic wireless cell phone booster system and how do I know if it will work for me?

A basic system includes an outside antenna to collect the signal from the cell tower, a signal booster to boost the signal, an inside antenna to broadcast the improved signal over the inside of the building or vehicle and cabling to connect the three parts together.

A wireless signal booster system will work for you if the outside signal is strong enough to enable you to make cell phone calls around the place where you want to put the outside antenna. It improves indoor cell phone signals by capturing and repeating the outside signals, bringing them into the building and enhancing them.

Can I leave my cell phone booster on all the time?

All 4A TECHNOLOGIES cell phone boosters can remain on all the time.

Can I leave my vehicle cell phone booster on all the time?

Leaving the car cell phone booster on when the vehicle is not running can discharge the battery in a day or two. As all of our vehicular boosters are supplied with cigarette lighter plug power supplies, you should verify that your cigarette lighter socket is not powered when the ignition key is off. If it remains on, 4A TECHNOLOGIES recommends that the cell phone booster is powered through the ignition switch (from the fuse block) so that the cell phone booster turns off and on with the vehicle ignition.

Can I wire the 12VDC power connection directly into my vehicle's electrical system?

Yes. Most of our cell phone boosters have a hardwire kit available that allows you to connect directly to the vehicle's electrical system. You can also cut off the cigarette lighter adapter plug and wire the cord into a fused circuit. If you use a circuit controlled by the ignition switch, you can turn the cell phone booster off and on with the vehicles key.

Does a 4A TECHNOLOGIES cell phone booster need to be professionally installed?

In most cases, you can install a 4A TECHNOLOGIES cell phone booster system yourself. 4A Technologies will provide online support, phone support, installation manuals & videos to help you to install the cell phone booster yourself.

Do I need to unplug the cell phone booster before I make a change to the system?

Yes. Unplug the cell phone booster from its power source any time you make a change to the system. This is especially true when an antenna is removed from the system. This prevents possible damage to the cell phone booster.

Will our cell phone boosters work on all frequencies?

Yes. 4A TECHNOLOGIES has cell phone boosters for single band, dual band & triple band that work with all analog and digital cell phone technologies, including CDMA, LTE(A/B/C/D), IDEN, CDMA, GSM & EGSM, DCS, PCS, CDMA, WCDMA, 3G, AWS, LTE2 and so on.
