Abstract
The invention relates to a method for concentrated transmission of multi-band and multisystem wireless signals. The method involves a base station, an access unit, an expansion unit and a far end unit, and the wireless signals pass through an up link and a down link; according to the up link, the wireless signals are transmitted out of the base station, enter the access unit, are transmitted to the expansion unit, are transmitted to a coverage unit through a cable or an optical line, and then are transmitted to a user through an antenna; according to the down link, the coverage unit receives information of the user, processes the signals and transmits the signals to the expansion unit through a cable or an optical line; the access unit packs and restores digital signals of the expansion unit and then transmits the digital signals back to the base station. The method is used for meeting the requirement that whole network coverage is achieved through single equipment when a mobile communication operator carries out network coverage, the problem that multiple system devices need to be erected at the same time is solved, and a great number of websites and transmission resources are saved.
Description
Technical field
The present invention relates to a kind of method of multiband multi-modulation scheme wireless signal concentration of transmissions.
Background technology
Mobile communication carrier cannot adopt when doing the network coverage single equipment realize the whole network cover, need the problem of simultaneously setting up multi-modulation scheme equipment, waste a large amount of sites and transfer resource.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of method of multiband multi-modulation scheme wireless signal concentration of transmissions.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method of multiband multi-modulation scheme wireless signal concentration of transmissions, and comprise base station, access unit, expanding element and far-end unit, wireless signal is respectively through up link and down link;
Down link is: wireless signal is spread out of by base station and enters access unit, signal is carried out digital processing packing by after wireless access system by access unit, then expanding element is transferred to, after the signal that access unit transmits by expanding element and WLAN broadband signal process, by netting twine or light transmission to capping unit, capping unit the signal that expanding element transmits is done amplify process, then through antenna transmission to user;
Down link: capping unit accepts the information of user, and capping unit processes signal, by netting twine or light transmission to expanding element; Access unit is transmitted through the fiber to after the signal that all capping units transmit by expanding element carries out digitized processing packing; Access unit transmits go back to base station by after the digital signal of expanding element packing reduction.
Further, described base station comprises TD-RRU, TD-LTE and GSM-BTS.
Further, described access unit comprises Digital IF processing unit, entering the Digital IF Processing of wireless signal through concentrating of access unit, by each railway digital signal multiplexing, producing a road high-speed digital signal.
