Dual bandsHuaptec DS30, 33, 37 are standardized industrial signal boosters aimed to expand coverage area of base mobile stations. The equipment supports two frequency bands within one system: EGSM+DCS or EGSM+WCDMA.
The digital dual band repeaters are a cost-effective way to improve business of mobile operators, economizing on installation of new mobile towers.Huaptec DS30, 33, 37 boosters have enough power (30, 33, 37 dBm) to provide excellent cellular signal over busy urban and rural areas up to 7000 m2.
Industrial dual band signal boosters are set up exactly to the bandwidth, supported by the mobile provider. With SDR technology it’s easy to change the chosen sub-bands and channels by the booster software to adapt the system to new environmental and network conditions.
We recommend choosing the following parameters for your digital amplifier:
Coverage area: DS30 – up to 5000 m2 (30dBm)
DS33 – up to 6000 m2 (33dBm)
DS37 – up to 7000 m2 (37dBm)
Two networks: EGSM+DCS/EGSM+WCDMA
1) Multi-band and multi-channel
Our industrial boosters are configured according to the specific requirements of the clients. DS30, 33, 37 dual band signal boosters support up to 8 sub-bands, which ensures system’s work in good linear state. The models also support up to 12 channels as per customer’s request.
2) Manual gain control (MGC)
MGC circuithelps to regulatethe repeater gain manually according to the strength of input signal. The function makes the booster performancesafer without interference withother areas.
3) Automatic gain/level control (AGC, ALC)
AGC and ALC circuits control the booster gain automatically depending on the outdoor signal reception conditions.It helps toavoid interference with other mobile operators’ frequencies and guarantee accurate and safe mobile signal amplification.
4) Noise floor level control
As far as each band creates some uplink noise, channel- and band-selective functions in the digital industrial boosters reduceoverall noise level. support all sub-bands within one frequency band, digital repeaters are much safer and do not disturbother operators’ BTSs.
5) OMT and OMC (Optional)
OMT and OMC are monitoring software circuits used to control from 50 (OMT) up to 2000 (OMC) signal boosters locally and remotely. The software obtain a number of functions such as control gain, alarm report, alarm review, etc. OMT and OMC come optional and are ordered per user’s request.
Huaptec industrial boosters comply with the industrial ETSI and 3GPP 3GPP2 technical standardsand are safe and healthy for humans. The equipment is also CE-certified and RoHS-compliant.Features
