Description
Technical field
The utility model relates to mobile communication technology field, particularly a kind of device that regulates aerial angle.
Background technology
An equipment crucial in mobile radio communication is antenna, antenna is to guarantee the transmitting of base station radio signal and the key equipment that mobile phone signal receives, because propagation performance and the surrounding environment of wireless signal are closely related, promote/control coverage, the signal that reduces minizone disturbs, and need to carry out regular adjustment to the angle of pitch of antenna.
At present, on general antenna, there is a set of " V " shape adjustable support to be installed on the top of antenna, the mechanism map of the mechanical antenna of tradition is shown in Figure 1: antenna 12, by adjustable antenna arm 13, mounting means 14 and lower installed part 15, is fixedly installed on pole 11; Upper bolt 16, upper fixture 17 and lower bolt 18,19 fixations of lower clamp.Concrete, adjust the angle of pitch of antenna by adjusting the adjustable antenna arm 13 of " V " shape, whole adjustment process is manual.
In order to address this problem, there is at present the antenna of can electricity adjusting the angle of pitch, by one or more phase shifters being installed in antenna inside, phase shifter can move up and down to change the length of feeding network, signal from input port to each output port be there are differences, thereby the phase place between change adjacent vibration generators, in the time that the phase place between adjacent vibration generators has certain rule, the maximum wave beam of aerial radiation just points to a specific direction.In the time of phase shifter continuous moving, just can realize the continuous electricity of wave beam and adjust, in the time that wave beam continuously changes in the vertical direction, just form the electricity regulation and control system of angle of declination.In general, realize electricity and adjust angle of declination, need a device that can regulate phase shifter, as RCU(antenna control unit of electromic tuning), this device can be built-in, also can be external, and regulate by base station software, network management center or handheld device etc.Therefore in the time using external controller electrical tilt antenna to regulate angle of declination, need to configure antenna control unit of electromic tuning, electrical tilt antenna control cables and handheld device (CCU).There is at present the local electricity of long-range electricity mediation to adjust two kinds of modes.
Although adjusting, long-range electricity there is many advantages, but current long-range electrical tilt antenna is popularized not yet in a large number, except the cost factor that large-scale production reason causes, a major reason is also to lack unified standard, this can not be integrated among a system antenna, change antenna provision business and mean on tower cabling again, thereby increased supplier and invest following uncertainty.
This blank has been filled up in the appearance of antennal interface standardization body (Antenna Interface Standards Group, AISG) just in good time.At the bottom of AISG is found in calendar year 2001, there are 37 members and 9 cooperation members (containing operator, scientific research institution, telecom equipment vendor and antenna manufacturer etc.), its task is for the data-interface of corresponding data transmission system antenna for base station creates open characteristic index (AISG-1), has extended at present tower amplifier field (AISG-2).AISG has formed a series of manuscripts, has mainly set the related specifications of antennal interface middle level 1, layer 2 and layer 7.Wherein, layer 1 is physical layer, has defined the master data characteristic including baud rate and input connector; Layer 2 is data link layers, is the customization subset based on ISO/IEC 13239:2000 (E) HDLC standard; Layer 7 is application layers, has defined accessing cost for data form and required control collection.
3GPP R7 has adopted most viewpoints of ASIG, uses its standard and in UTRAN universal architecture, has introduced an Iuant interface, includes RET in and controls function, and in Release6, defined a series of document in base station.
Current, there is both at home and abroad many antennas producer that the RET system of deferring to international standard can be provided, some antenna system has also been carried out the IOT test job with main equipment manufacturer.
There is following defect in existing technology: because antenna major part is arranged on the sky that stretches out 1-2 rice outside steel tower, or be contained on the pole that exceeds roof 3-4 rice, adjustment personnel need to lean out steel tower by health, or climb up support with high ladder, and personal safety is had to certain threat; The more common antenna of local electrical tilt antenna purchase cost is high, and has at present the common antenna of a large amount of storages, can not all be replaced by electrical tilt antenna; And the interface of long-range electrical tilt antenna unifies still to need time.
