Huaptec DS 23, 27 are digital signal amplifiers for industrial use. The devices are designed to extend coverage area of mobile base towers over rural, residential zones and large indoor objects such as shopping malls, leisure centers, hotels, railway station, subways, etc. DS 23, 27 booster models are quad band and perform at four signal standards at a time – EGSM 900 MHz, DCS 1800 MHz, WCDMA 2100 MHz and LTE 2600 MHz.
Digital mobile signal boosters are adjusted accurately to the requirements of a mobile provider. Each working bandwidth of the amplifier supports 8 sub-bands and 12 channels. No interference with competitor operators is guaranteed, since the devices provide rejection of other bands up to 50 dBc. With SDR technology it’s possible to adjust the digital amplifiers to new bandwidths by the software if necessary.
Digital signal amplifiers cover the following areas:
DS23 – up to 3000 m2 (23 dBm)
DS27 – up to 4000 m2 (27 dBm)
1) Multi-band and multi-channel
Each network system in the booster supports up to 8 sub-bands and 12 channels according to the needs of the client. Multi-band and multi-channel functions make digital signal boosters work in better linearity with the base mobile tower and amplify the bandwidths of a certain mobile provider, avoiding interference with competitors. Since each band makes some noise, channel- and band-selectivity also reduce the overall noise level.
2) Manual gain control (MGC)
MGC circuit regulates booster’s uplink and downlink gain depending on the outdoor signal reception. It saves the booster from sending too much power to the base mobile tower if the cell phone signal outdoors is rather strong and provides safer signal amplification for users.
3) Automatic gain/level control (AGC, ALC)
AGC and ALC circuits automatically control the power balance between the signal amplifier and the mobile base station according to input signals. The functions are available both for uplink and downlink. The controls prevents from cell tower interference and booster overload.
4) OMT and OMC (Optional)
These are monitoring software for local and remote booster control. OMT and OMC support from 100 to 2000 items respectively. Both software provide gain control, alarm report, alarm review and OMC has a number of advanced features such as security management, alarm analysis, etc. The software are optional and are ordered with a booster upon client’s request.
Huaptec DS23, 27 digital signal amplifiers are CE-certified and RoHS-compliant. The equipment conforms to the European quality standards and is confirmed to be safe and healthy for humans. Huaptec industrial boosters are also allowed for work with mobile operators since they conform to the international 3-d generation telecommunication standards ETSI and 3GPP 3GPP2.FeaturesReviews
