Background technology
In Radio Network System, the antenna subsystem of communication base station comprises RRU and antenna element, and RRU links to each other with antenna element, is used to realize the reception and the transmission of wireless signal.
Fig. 1 a shows the perspective view in a kind of antenna element front in the prior art, and Fig. 1 b shows the perspective view of a kind of RRU in the prior art.As shown in Figure 1a, antenna element comprises: radio frequency interface 11, antenna coupling disc 12 and nonmetal bucker 13.Wherein, radio frequency interface 11 is as the external interface of antenna coupling disc 12, be used for linking to each other with RRU, its included port number is relevant with the passage number that communicates, Fig. 1 a shows the situation of eight passages, this moment, port number was nine, comprised and corresponding eight access ports of each passage and a calibration port.Antenna coupling disc 12 be used to the to be coupled signal of each passage is calibrated the signal of smart antenna.Nonmetal bucker 13 is used to protect the indoor design of antenna element, and prevents that rainwater etc. from entering antenna element inside.Shown in Fig. 1 b, RRU comprises: radio frequency interface 21 and antenna filter 22.Wherein, radio frequency interface 21 is as antenna filter 22 and the external interface of calibrating signal (if comprising calibrating signal), be used for linking to each other with antenna element, its included port number is relevant with the passage number that communicates, Fig. 1 b shows the situation with corresponding eight passages of Fig. 1 a, this moment, port number was nine, comprised and corresponding eight access ports of each passage and a calibration port.Antenna filter 22 is used for signal is carried out filtering.
At present, normally separate to install between RRU and the antenna element, be to connect by radio frequency cable wire jumper between radio frequency interface 11 on the antenna element and the radio frequency interface 21 on the RRU, need the joint of each wire jumper be docked during construction, processing such as locking and junction waterproof.Fig. 1 c shows a kind of planar structure schematic diagram after antenna element and RRU are installed in the prior art.Shown in Fig. 1 c, antenna element 1 is installed on the pole 3 by accessory is installed, RRU 2 also is installed in (or other position on the pole 3 by accessory is installed, on platform, wall is first-class), afterwards, connect by the radio frequency cable consistent 4 again between the radio frequency interface of antenna element 1 and RRU 2 with the port number of radio frequency interface.
But there is following shortcoming in the above-mentioned mounting means:
When 1, the radio frequency interface of antenna element and RRU being connected by the radio frequency cable, difficulty of construction and workload are bigger, especially for the multi-channel intelligent antenna system of TD SDMA (TD-SCDMA) system, be easy to generate construction quality and reliability problems, and be not easy to dismounting and maintenance.Such as in eight passage RRU of TD-SCDMA system, nine radio frequency cables (calibration mouth will be arranged, eight antenna opening), promptly each sector needs nine radio frequency cables, and a general website is wanted three sectors, then need 27 radio frequency cable wire jumpers altogether, the joint of each wire jumper all will be done water-proofing treatment during construction, and eight passage RRU will do antenna element and RRU both sides being connected and water-proofing treatment of totally 54 joints under three sector situations, its construction working amount is very big, and also there is hidden danger in the reliability aspect.In addition, when safeguarding, to each sector all need the to dismantle adhesive waterproof tape or the heat-shrinkable T bush of nine joints, difficulty of construction is also bigger.
2, need the radio frequency cable of certain-length to be connected between antenna element and the RRU, the loss that this has additionally increased radiofrequency signal has caused the waste of the energy.
3, the installation of RRU needs extra installing space and accessory is installed, and this has increased the extra demand to installation environment, and the demand that accessory and radio frequency cable are installed has simultaneously also increased the integrated cost of whole system.
4, owing to RRU, radio frequency cable, antenna element disperse to install, occupation space is bigger, makes visual effect relatively poor.
