Frequently Asked Questions
What can I expect the cell phone signal range and strength to be inside the building?
e closer you are to the base, the stronger the signal. is will vary with di erent conditions. Some of the
conditions that will a ect the improved coverage area are signal strength outdoors, the type of building
materials, the placement of the unit and the antenna’s proximity to cellular towers.
You can expect that indoor coverage will be improved. People will be able to make calls where they couldn’t
before. e degree of improvement will depend upon many factors. e 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 uctuate in a similar fashion.
Is a cellular phone signal booster the same as a wireless router; will it help Wi-Fi signal?
e zBoost unit will not help WiFi service. is unit is designed to work with wireless PCS and Cellular
phones and devices. WIFI operates on a di erent 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 cant increase of 2x, 6 dB is 4x, and 10 dB is
10x. On a four bar phone, one "bar" equals about 10 dB.
e increase in signal you will see depends upon:
• e level of signal at the External Antenna (outdoor)
• e care of the antenna placement (two feet away from metal, adequate antenna separation [15 feet
recommended])
• e signal already present inside (related to building losses)
• e distance of mobile devices from the Base Unit (signal spreads or diminishes rapidly with distance.)
There are usually several cell phones in use at one time in this office, will your product boost all signals
simultaneously?
e zBoost YX741 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.
Frequently Asked Questions
Where should I put the Indoor Antenna to get the best coverage?
You should install the Indoor Antenna where coverage is needed the most. e Indoor Antenna is the
component that ampli es the signal inside. e coverage area and direction is dependant on the type of
antenna used (directional or omnidirectional). e further away the phone is from the antenna, the weaker
the signal. e antenna be placed in a central meeting room, lobby, or other central location.
Note: if you install the External Antenna too close to the Indoor Antenna, the system will shut down (red
light will blink). is is a normal condition for this scenario. It means that you must ensure a su cient
distance between the 2 antennas; otherwise, it will detect feedback or noise and will automatically shut
down.
Where is the best place to put the zBoost External Antenna?
e zBoost External Antenna should be placed at the highest point in order to “catch” the strongest signal.
is location will likely be on the roof. e placement of the External Antenna is very important. It is best
to place this in an unobstructed area, preferably above the roof line.
Note: if you install the External Antenna too close to the Indoor Antenna, the system will shut down (red
light will appear). is is a normal condition for this scenario. It means that you must ensure a su cient
distance between the 2 antennas; otherwise, it will detect feedback or noise and will automatically shut
down.
The light is continually blinking
ere are several reason that the zBoost light could be blinking. Please see the Light Indicator section on
