RF repeater user's manual
Installation / commissioning of RF repeaters by anyone, is done at own risk.
Thank you for choosing our mobile phone repeater.
Nowadays, people use mobile phones everywhere. But, unfortunately, due to loss of wireless signal transmissions (wireless), in
different environments, and also due to the effect of building walls, there will be some areas of weak signal, or even mild loss of data
even around the GSM signal station. This can lead to missed opportunities of business for example.
The repeater can amplify the signal required for the cell phone to work under normal conditions. Please read the user's manual
before use, installation and commissioning.

Functions
.
People can communicate easily using a mobile phone, that is very true. Because the effect of obscurity in wireless
communications and electromagnetic shielding, when people get into spaces like hotels,buildings,offices,underground parking
lots, mobile signal disappears, so that it becomes impossible to use your mobile phone. Sometimes this can cause loss of data
and valuable information for the period in which no signal is received and also can imply financial losses.
The RF repeater (GSM,3G, 4G ) is a low power device that compensates for the lack of signal and covers a limited land area to
ensure communication with the mobile phone. Our repeaters operate on full duplex (talk and listen in the same time).
The full duplex repeaters are equipped with SAW filter (surface acoustic wave) and ALC (automatic gain control level), have a
low power, are safety in operation, low noise and a linear gain over the entire bandwith.
2. Characteristics
Adopts two ports built in full duplex mode
It's practical, easy to use and to install
It is reliable, designed to meet the standards EN 60950-1 + A11, EN 301 489-1/-8, EN 301 502. ATT & ALC Auto-adjustment of
signal level

- Page 4 ( Yagi ) from the indoor antenna ( panel or ceiling ) for not to cause self-oscilation of the RF repeater. This can easily be done by positioning the two antennas ( indoor and outdoor) one-under-side and back-to-back, as the sketch above.
- Page 5 The device is a RF wide band repeater, making the following situations requiring attention: Where there are more than 2 mobile operators, working in the same frequency band of the repeater, and a BTS is located a few hundred feet from the installation site and the other mobile operator has the BTS a little further, then the dominating signal will be amplified with priority.
- Page 6 Strong signal in some places, weak in the remaining locations It means that power is unevenly distributed due to irregularities due to the internal antenna. If the signal is weak in several positions, you can distribute a line from the amplifier, so many places to be covered properly by using a splitter and extra indor antennas - but should be taken into account that the signal emitted by many indoor antennas will subside and then you will need to use a repeater with higher output power and gain.
