The beneficial effects of the utility model are: original wireless CPE terminal be directly connected be separated with reception smart antenna, connected by 1/2 feeder line extended line, smart antenna is extended to the outside of room, cabinet, case, the impact of separating signal shielding, be no more than the condition of 25 meters at feed line length under, effective raising cpe device received signal level, and then improve the stability of distribution automation service operation.
Accompanying drawing explanation
Fig. 1 is scheme of installation of the present utility model;
Fig. 2 is structure chart of the present utility model;
In figure: distribution ring main unit 1, CPE terminal 2, antennal interface 3, extended line 1, joint 5, extended line 26, wall bushing 7, bent antenna 8, upright antenna 9.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
The CPE terminal antenna extending structure of a kind of electric power TD-LTE, comprise distribution ring main unit 1, CPE terminal 2, antennal interface 3, extended line 1, joint 5, extended line 26, wall bushing 7, bent antenna 8 and upright antenna 9, described CPE terminal 2 is arranged in distribution ring main unit 1, the quantity of antennal interface 3 is two or more, be arranged in CPE terminal 2, the quantity of wall bushing 7 has two, penetrate the top being arranged on distribution ring main unit 1, by the inside of distribution ring main unit 1 and ft connection, bent antenna 8, upright antenna 9 is arranged on the outside of distribution ring main unit 1, antennal interface 3 by extended line through wall bushing 7 respectively with bent antenna 8, upright antenna 9 is connected to each other, extended line comprises extended line 1 and extended line 26, extended line 1 is positioned at the outside of distribution ring main unit, extended line 26 is positioned at the inside of distribution ring main unit, antennal interface 3 is connected to each other by joint 5 and extended line 1, bent antenna 8, upright antenna 9 is connected to each other by joint 5 and extended line 26.
Described extended line 1 and extended line 26 are 1/2 feeder line, and joint 5 is 1/2 feeder line adapter.
In actual applications, when making Antenna extender line, intercept suitable length feeder line (3 meters) by field demand, feedback head is carried out at two ends; Connect CPE joint and feeder head, another termination 1/2 feeder line adapter female of feeder line, then feeder line adapter is connected with LTE antenna; Same manner extends another root LTE antenna, and so far LTE antenna physics prolongation connection completes.
CPE external antenna has 6dB (decibel) left and right gain, 1.8G TD-LTE system 1/2 feeder line (within length 25 meters) feeder line is 10.10dB/100m(rice to the maximum), this project chooses 3 meters of feeder lines, theory wire loss value is 0.303dB, single feed line 2 feedback head Insertion Loss is at about 1dB, and the total losses of two antennas are probably at 2.606dB.
On-the-spot actual test result shows: signal strength signal intensity-76 dB not using extension antenna test, uses the signal strength signal intensity-107dB after Antenna extender line, and the signal intensity ratio after use Antenna extender line to be eager to excel 30dB without the signal strength signal intensity of Antenna extender line.
By the use of Antenna extender line, enhance the intensity that CPE receives base station signal, and then improve the stability of distribution automation service operation.
