Distributed broadband wireless coverage and broadband cabled access connecting system and realization method thereof

Abstract

The invention discloses a distributed broadband wireless coverage and broadband cabled access connecting system and a realization method thereof. The technical problem to be solved is the wireless coverage and cabled access and connection of the distributed broadband superposed in a 2G / 3G indoor distributed network. The system comprises a broadband IP network access controller, a multi-medium remote adapter, a mixer, a cross-over device, a cabled network terminal adapter and a remote telecom network management system. The realization method comprises the following steps of: arranging a working frequency, transmitting broadband multiple carrier digital signals with the frequency selected by the system into an active trunk amplifier and an antenna-feeder branch network covered by a 2G / 3G in an indoor distributed system, wirelessly accessing in a broadband metropolitan area network through a system broadband and cably accessing in a broadband metropolitan area network through a system broadband, thereby realizing realizing management and control. Compared with the prior art, the idle frequency band in the 2G / 3G indoor distributed system is used for realizing the distributed WLAN broadband wireless coverage and broadband IP cabled access connection system superposed in the existing 2G / 3G indoor covered system network.

Description

technical field [0001] The present invention relates to a communication system and method for a wireless mobile coverage network and a wired fixed access network, especially a distributed WLAN & IP broadband wireless coverage and broadband wired access connection system superimposed on a 2G / 3G indoor distribution network and Its implementation method. Background technique [0002] With the development of third-generation 3G mobile communication technology at home and abroad and the needs of operational services, mobile communication operators in various countries have upgraded their existing 2G indoor coverage systems to enable them to cover 3G signals. At the same time, due to the needs of 3G mobile data service coverage and terminal reception, operators also need to carry out WLAN-based wireless signal coverage; and because the cost and stability of wired broadband access are better than wireless mobile access, therefore, full-service (wireless and cable) operators will n...

Problems solved by technology

The prior art mobile communication network access indoor coverage system and method has the following disadvantages: the mobile communication multi-network tandem indoor coverage system with patent No. 02249827.3 has a large feeder attenuation for WLAN signal 2.4GHz combiner insertion loss , under the same coverage power requirements of the antenna, the WLAN signal source requires higher power, which is not environmentally friendly and economical

Patent No. 200320108961.1 is a power amplifier used in wireless local area network indoor coverage system. Just increasing the power of WLANAP cannot solve the problem of WLAN indoor coverage, and it is not environmentally friendly and consumes a lot of power

The patent No. 03256238.1 is an access point for wireless local area network indoor coverage system, which cannot solve the problems of large wiring engineering, many active devices and low coverage efficiency in indoor coverage systems.

To sum up, the basic types of traditional multi-band indoor coverage, WLAN coverage and access solutions are as follows: (1) IP signal source + network cable + AP standard power, there are problems: wiring is required, and indoor coverage is small

(2) IP signal source + network cable + high-power AP + multiple antennas, there are problems: wiring is required, the line consumption is large, the effective power of the wireless system is low, the power consumption is large, and it is not environmentally friendly

(4) The indoor coverage of the multi-band network is limited to the combined wireless coverage of 2G, 3G, and WLAN. Power AP, etc., the construction cost is high, more high-power AP will produce harmful radiation to the human body, will bring higher noise floor to the indoor distribution system, and more likely to generate mutual interference between 3G and WLAN
