Abstract
The utility model discloses a wireless-coverage active light distribution system which comprises base stations or RRUs (Radio Remote Units), an MCU (Main Connection Unit), an ECU (Expanded Connection Unit) and an RCU (Remote Connection Unit), wherein the base stations or RRUs are distributed in different places. The MCU receives GSM, TD-SCDMA, LTE MIMO1 and LTE MIMO2 radiofrequency signals from the base stations or RRUs, and the MCU is connected with the ECU via a cable. The ECU is connected with the RCU via a flexible cable, and the RCU is then connected with an antenna feed system. Uplink and downlink signal transmission is included in a working method, transmission is separated from radio frequency, frequency shift transmission employs the same transmission line, and subsequent network development technology can be smoothly developed to.
Description
Technical field
The utility model relates to Wireless Telecom Equipment technical field. be specifically related to a kind of active smooth compartment system of wireless coverage.
Background technology
Along with the development of communication network, operator need to repeatedly design in the process of network evolution, and repeatedly budget, repeatedly marches into the arena, repeatedly construction.The multi-band signal that existing network overlay system can not be realized or can not well realize in evolution process closes road.
Along with the development of network, user's communication requirement is also constantly being moved to mobile communication business from fixing speech business.The Internet era that 4G (TDD-LTE) network and rear 4G on the horizon being all high-speed mobile cybertimes.The business such as mobile phone wireless online, transmission of video images are more and more higher to the requirement of signal bandwidth, and traditional network coverage equipment and technology more and more can not meet the demands.
Meanwhile, existing soverlay technique is excessive without source range, can not carry out precise management to the equipment in covering system, builds difficulty, and troubleshooting difficulty, may cause cost and the revenue losses of operator.
Utility model content
The utility model is for above-mentioned the deficiencies in the prior art part, a kind of active smooth compartment system of wireless coverage is provided, this system has not only solved multi-band signal and has closed road and network coverage problem, has also realized the smooth evolution of network technology, and can realize becoming more meticulous of webmaster.
For achieving the above object, the utility model provides a kind of active smooth compartment system of wireless coverage, comprises distribution base station or RRU everywhere, and this system also comprises the main access unit of MCU(), ECU(expands access unit), RCU(distance connection unit); Wherein MCU receives from base station or RRU (Radio Remote Unit, Remote Radio Unit) GSM, TD-SCDMA, LTE MIMO1, LTE MIMO2 radiofrequency signal, between MCU and ECU, adopt optical cable to connect simultaneously, between ECU and RCU, adopt flexible-cable to connect, RCU is connected with antenna-feedback system again.
The active smooth compartment system that the utility model provides not only open realization the existing and issuable multi-band signal of follow-up evolution close road function, and make covering system power realize coupling design flexibly and reset meter by three-level network framework, and utilize fiber optic stretch to expand signal cover; By multi-band signal business, with cable, carry, can effectively avoid compartment system to build overlapping investment simultaneously; By the active far-end that extends to, realized becoming more meticulous of webmaster; A kind of many network signal carrying covering effective ways of realizing.
Accompanying drawing explanation
Fig. 1 is the active smooth compartment system frame diagram of the utility model wireless coverage.
Embodiment
Below in conjunction with accompanying drawing, the enforcement of this technical scheme is described in further detail.
The utility model discloses a kind of active smooth compartment system of wireless coverage.This system group network is three-level structure, is divided into: tri-grades of main access unit MCU, expansion access unit ECU, distance connection unit R CU.Wherein MCU receives GSM, TD-SCDMA, LTE MIMO1, the LTE MIMO2 radiofrequency signal from base station or RRU, adopts optical cable to connect between MCU and ECU simultaneously, adopts flexible-cable to connect between ECU and RCU, and RCU is connected with antenna-feedback system again.This system comprises LTE in interior Wireless multi-band multiplexel circuit covering and webmaster problem for solving, and the utility model content includes but not limited to illustrate radiofrequency signal carrying.
Fig. 1 is the active smooth compartment system frame diagram of the wireless coverage that the utility model proposes.Signals transmission is as follows:
(1) MCU accepts GSM, TD-SCDMA, LTE MIMO1, the LTE MIMO2 radiofrequency signal from base station or RRU; Radiofrequency signal is changed into light signal, and shift frequency is to the less frequency range of attenuation loss, is transmitted through the fiber to ECU;
(2) ECU accepts MCU and passes the light signal of coming, and changes light signal dress into the signal of telecommunication, by flexible-cable (contain coaxial flexible cable or 5 classes, surpass the flexible-cable media such as 5 class lines), transfers to RCU;
(3) RCU accepts ECU and passes the signal of telecommunication of coming, and shift frequency converts back signaling protocol frequency range separately, the radiofrequency signals such as output GSM, TD-SCDMA, LTE MIMO1, LTE MIMO2, optional portion combiner;
(4) GSM, TD-SCDMA, LTE MIMO1, the LTE MIMO2 radiofrequency signal of output are sent to external antenna-feedback system settling signal covering.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
Claims (1)
1. an active smooth compartment system for wireless coverage, comprises distribution base station or RRU everywhere, it is characterized in that, this system also comprises MCU, ECU, RCU; Wherein MCU receives GSM, TD-SCDMA, LTE MIMO1, the LTE MIMO2 radiofrequency signal from base station or RRU, adopts optical cable to connect between MCU and ECU simultaneously, adopts flexible-cable to connect between ECU and RCU, and RCU is connected with antenna-feedback system again.
