Huaptec DS 23, 27 are high-power cell phone signal repeaters for industrial use. Both models combine three frequency bands in one system – EGSM 900 MHz, DCS 1800 MHz and WCDMA 2100 MHz. The equipment is aimed at either mobile providers to broaden their networks or large-scale projects to cover such areas as railway stations, airports, shopping malls, entertaining centers, rural and urban zones, etc.
Industrial cell phone repeaters Huaptec DS 23, 27 are tuned thoroughly to the bandwidths of a mobile operator. Digital filters enable the booster to have about 50 dBc of band rejection. If the operator happens to change the working sub-bands and channels, it’s easy to readjust the booster by the software, empowered by SDR technology.
Choose coverage area for your tri band mobile booster:
DS 23 – up to 3000 m2 (23 dBm)
DS 27 – up to 4000 m2 (27 dBm)
1) Multi-band and multi-channel
Each frequency band in the booster supports up to 8 sub-bands and 12 channels. Multi-band and multi-channel functions allow adjusting the system to the needs of the client without disturbing competitors.
2) Noise floor level control
Thanks to channel- and band-selectivity, the repeater guarantees efficient noise level control. It’s easily explained by the fact, that cell phone amplifiers, which support bands of all mobile operators, create much more noise and increase the risk of interference with cell towers of the competitors.
3) Manual gain control (MGC)
Manual gain control allows regulating the booster gain in accordance with input signals. This function ensures more accurate gain specifically to the client’s requirements.
4) Automatic gain/level control (AGC, ALC)
AGC and ALC function adjusts the cell phone repeater gain automatically depending on the input signal strength. The circuits also alarm in case of cell tower interference, providing safer booster functioning.
5) OMT and OMC (Optional)
OMT and OMC are monitoring software aimed at local and remote booster control. OMT is able to monitor 100 units at a time, while OMC - 2000 units. The software also has such functions as gain control, alarm report, alarm review, etc. Both monitoring systems come optional and are ordered per request.
Huaptec industrial tri band cell phone amplifiers comply with the international ETSI and 3GPP 3GPP2 technical standards. The equipment also fully meets CE and RoHS certifications and is confirmed to be safe and healthy for humans.COMMENTAIRES
