Overview:
SY-DB-**-**S dual system band selective signal repeater series are designed for the mobile operator indoor coverage solution. They are used in the some hot sites, where have the high traffics and are not worth to install a Micro BTS.
Using the dual band selective repeater can easily realize the fast coverage of different services.
The mobile operator could use it to amplify its own signal only and make it better than the signal of rivals which can lead the competition.
Repeater fully and completelly complies CE directives.
We guarantee all parameters compliance to required standards.
Operation Frequency bands:
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
All band widths can be selected by operator
Features:
1. With IF SAW filter technology for good out of band rejection, the band selective repeaters is designed to selective specific sub-bands of mobile system.
2. Optional function moves central frequency via local USB or remotelly via wireless modem. With this function possible change to other operator band.
3. Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.
4. 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.
5. Auto shut off function automaticly shuts down power in case of overload or interferences.
6. The repeater can be locally (by USB) and remotely (by wireless cellular modem) monitored and controlled through it's monitor module by OMT or OMC Software (Optional). Software is Free of charge and does not requires subscription fee.
