Overview: FDB-**-** dual system Full Band signal repeater series are designed for the customers indoor coverage solution. They are used in the some hot sites, where signal of mobile operators service is too low. Using the full band repeater can easily realize the fast coverage.
Dual system repeater amplifies two different band signal and can supply two different services of mobile operator.
Customer could use it to amplify all operators in selected two bands. All people living and working in building also visitors can use both band signals.
Repeater fully and completelly complies CE directives. We guarantee all parameters compliance to required standards.
Operation Frequency Band.
Any combinations of selected two bands are possible.
-
LTE800 (L8)
-
GSM900 & EGSM (G & E)
-
LTE1800 / DCS1800 (D)
-
WCDMA2100 / LTE2100 (W)
-
LTE2600 (L26)
-
and so on.
So on request are possible combinations : L8+G, L8+E, L8+D, L8+D, L8+W, L8+L26, G+D, G+W, G+L26, E+D, E+W, E+L26, D+W, D+L26, W+L26
Features:
1. Industrial repeater technology provides high level out of band rejection. With IF SAW filter technology for good out of band rejection, this full band repeater is designed in the same high level way as industrial band selective repeater.
2. Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.
3. 31dB MGC (Manual gain control) 1dB per step available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintenance.
4. Auto shut off function automaticly shuts down power in case of overload or interferences.

5. Optional monitoring function can do locally (by USB) monitoring and controlling operation of repeater. In case if there are installed many repeaters, distributor can remotely (by wireless cellular modem) monitor and controll through it's monitor module by OMT or OMC Software. (Optional) Software is free of charge and does not requires subscription fee. |
