The all-band mobile amplifier is the most complete solution:
Having a mobile amplifier for all bands you no longer have to worry about frequencies or standards, because it covers them all.
-
The antenna located on the roof receives signal in the 4 frequency bands used in mobile telephony (2G+3G+4G/LTE). The signal is conducted through the coaxial cable to the all-band mobile amplifier installed inside the house.
-
The 4-band amplifier amplifies the signals and rebroadcasts them in the area where you need coverage.
-
Your cell phones, laptops and tablets can now communicate thanks to these amplified signals.
This amplifier amplifies all networks and all frequencies:
GSM (900 and 1800Mhz), 3G (2100Mhz) and 4G (800/1800Mhz).
Touch control


A: Main screen. Here you can see the signal strength in each band, represented with green signal bars. There is a status window underneath, telling you what is happening.
The blue icon is the upstream channel. It lights up when you initiate a call or data connection using that band.
The colored boxes on the right show you the status of the band:
- ADJ: the band is adjusting and optimizing its power.
- HI: this tells you that there is a strong signal coming from the antenna; you don't have to do anything.
- OSC: this tells you that there is oscillation between the outer and inner antenna. You should make sure that there is at least one solid wall separating the antennas.
- OFF: this means that the band has been disconnected.


B: Decibel display. Here you can see the detailed values of all parameters, in decibels.
C: Here you can see which bands are most used, and you can also switch any band on or off.
D: From here you can attenuate any band.
To sum up:
As you can see, the mobile amplifier for all 4 bands does it all: you don't have to know in which frequency your operator broadcasts each standard, nor in which one will broadcast them in the future with the arrival of the new 4G networks. With this amplifier you anticipate the future.
how does it work?
-
An antenna is installed on the roof of the house, and it captures the mobile signal coming from all operators. This signal travels through a coaxial cable to the amplifier.
-
The repeater amplifies the signal in both directions (to and from the house), and distributes it throughout the house.
-
Thanks to the amplified signal, your mobile devices can now communicate without any problems.
