Nikrans NS-10003G Signal Booster
1. Purpose
As the domestic mobile communication industry
develops rapidly, the amount of mobile communications
users increases so steadily that the cell planning gets
smaller and smaller while the base station positions get
lower and lower. On the other hand, as city construction
develops, more and more high-rise buildings are set up
constantly, based on the shadow effect of the radio
propagation, the mobile communications may get a signal
blind spot behind or between the buildings. Moreover, in
order to avoid interference from adjacent districts, the main
lobe of the antenna radiation orientation of the cell mobile
communication base station in construction has a bigger
down-tilt obliquity, thus the signals usually can not be
received effectively in the high and medium parts of the
high rise buildings. Furthermore, due to the shield effect to
electro-magnetic waves caused by buildings, the mobile
communication signals cannot be received in tunnels,
subways, underground stores, entertainment complex,
parking fields, hotels, office buildings and other large-size
and closed buildings.
Signal amplifier is an effective device that makes up
the insufficient base station coverage in the mobile network,
enlarges the coverage area of the base station and fills in
the blind spots, which adopts double-ended duplex design
and external power supply with advantages of convenient
mounting and high reliability. The bandwidth of the signal
amplifier may cover GSM 25MHz/19 MHz/ 6MHz,
CDMA10MHz/DCS75 MHz with compatibility between
digital system and analogue system.
2. Technical features
