Frequently Asked Questions
What can I expect my cell phone signal range and strength to be inside my home?
The closer you are to the base, the stronger the signal. This will vary with different conditions. Some
of the conditions that will affect the improved coverage area are signal strength outdoors, the type
of building materials in the home, the placement of the unit and the antenna’s proximity to cellular
towers.
You can expect that your indoor coverage will be improved. You will be able to make calls where
you couldn’t before. The degree of improvement will depend upon many factors. The intent of
zBoost products are to bring outside coverage inside. Just as the signal bars move up and down
when outside, the boosted signal will
fl
uctuate in a similar fashion.
Is a cellular phone signal booster the same as a wireless router; will it help my WiFi signal?
The zBoost unit will not help your WiFi service. This unit is designed to work with wireless PCS and
Cellular phones and devices. The WIFI in your home operates on a different frequency.
Why isn’t my cell phone indicating more signal with more bars?
You may not always observe more bars that gain on your signal meter because of the signal
spreading out from the antenna. If your phone has a dB meter, 3 dB is a signi
fi
cant increase of 2x,
6 dB is 4x, and 10 dB is 10x. On a four bar phone, one "bar" equals about 10 dB.
The increase in signal you will see depends upon:
•
The level of signal at the External Antenna (outdoor)
•
The care of the antenna placement (two feet away from metal, adequate antenna
separation [15 feet recommended])
•
The signal already present inside (related to building losses)
•
The distance of your phone/device from the Indoor Antenna (signal spreads or diminishes
rapidly with distance.)
Also, if your phone uses LTE, it likely displays LTE signal level instead of 3G when a call is being
placed.
There are usually several cell phones in use at one time in my home, will your product boost
all of our signals simultaneously?
The zBoost is designed to cover multiple signals simultaneously and will allow multiple users to
operate at the same time.
Does the zBoost work if you have no bars?
No, if no signal is present outdoors zBoost products will not work for you. Also, keep in mind if your
best signal is 1 bar at the External Antenna, your coverage will be limited to a small room. You
could improve that with an upgraded antenna. (See page v).

The Manufacturer’s rated output power of this equipment is for single carrier operation. For
situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB,
especially where the output signal is re-radiated and can cause interference to adjacent band users.
This power reduction is to be by means of input power or gain reduction and not by an attenuator at
the output of the device.
