Huaptec DS23, 27 are industrial high-power cell phone repeaters standardized in conformity with ETSI and 3GPP 3GPP2. The models are quad band and support four networks in a single system – EGSM 900 MHz, DCS/LTE 1800 MHz, WCDMA 2100 MHz and LTE 800 MHz. Digital industrial boosters are mostly used by cell phone providers to expand the coverage area of their BTSs or for specific projects to cover such large areas as airports, railway stations, shopping malls, hotels, hypermarkets, etc.
Digital mobile repeaters adopt advanced technologies and are able to amplify the bandwidth of a certain mobile provider and reject the others (band rejection value is up to 50 dBc). Bandwidth adjustment is made at the manufacture in accordance with client’s needs. In case the operator is eager to change the bandwidth, the repeater allows doing it by the software without a hardware replacement.
Choose coverage areas for your quad band cell phone repeater:
DS 23 – up to 3000 m2 (23 dBm)
DS 27 – up to 4000 m2 (27 dBm)
1) Multi-band and multi-channel
Huaptec DS23, 27 models support up to 8 sub-bands and up to 12 channels within each of four frequency bands. It allows adjusting the booster accurately to the bandwidths, the mobile provider works at. Narrow band as well as multi-band and multi-channel functions protect the booster from interference with other operator’s frequency bands.
2) Noise floor level control
As far as amplification of each band makes some noise, thanks to channel- and band-selectivity digital cell phone repeaters guarantee lowest noise level possible and no interference with other mobile operators’ bandwidths. In comparison, mobile boosters for personal use cause more noise, since they amplify all the bands to cover all possible mobile operators.
3) Manual gain control (MGC)
Manual gain control allows regulating the balance between a cell phone booster and a base mobile tower basing on input signal strength. The function helps to avoid any troubles with cell tower interference and booster overloading.
4) Automatic gain/level control (AGC, ALC)
AGC and ALC automatically regulate the repeater’s gain depending on the strength of input signals. The circuits help to escape cell tower interference and provide safe signal amplification for users.
5) OMT and OMC (Optional)
OMT and OMC are monitoring software for local and remote control of up to 2000 boosters. Apart from monitoring the systems provide gain control, alarm report, alarm review and other functions. The software are optional and are available per customer’s request.
Huaptec industrial cell phone boosters fully conform to CE and RoHS international certifications of safety and quality. The equipment also complies with the technical ETSI and 3GPP 3GPP2 standards.FeaturesReviews
