Multi-mode access novel EOC device

Abstract

The invention discloses a multi-mode access novel EOC device which is a new device further developed on the basis of a conventional point-to-point low frequency modulated EOC device. The multi-mode access novel EOC device comprises a central office end device and a user terminal device connected with the central office end device through a coaxial cable. The central office end device comprises a wireless signal and CATV cable television signal combiner unit, and a wireless signal and CATV cable television combination signal and modulated Ethernet data signal combiner unit. The combination signals of already modulated Ethernet data signals, wireless signals and cable television signals are mixed and then are output through the coaxial cable, multi-service transmission and global management and control can be simultaneously realized, the device is used for simultaneous access of network data signals, the cable television signals and the wireless signals, indoor coverage of the wireless signals is realized, and the functions of networking, TV watching and the like on cable television network broadband are achieved.

Description

technical field [0001] The invention relates to an access system for wireless signal coverage, in particular to a deep coverage system for realizing wireless signal entry into buildings or households by using CATV coaxial cables in combination with EOC equipment. Background technique [0002] The number of mobile phone users in China is constantly increasing. According to the latest figures disclosed by the three major domestic operators, as of January 2012, the number of mobile phone users in China has reached 987.58 million, which is about to approach the 1 billion mark. With the rapid increase of mobile users and the increasing number of high-rise buildings, residential areas, hotels, and office buildings, the traffic density and coverage requirements are also rising. These buildings use a large number of building materials such as reinforced concrete, which have a strong shielding effect on mobile phone signals. In the environment of low floors of large buildings, under...
