Embodiment

[0021] The OLT device proposed by the present invention to realize integrated access of EPON and wireless technology is responsible for managing 32 ONU devices on the user side, 10 WiMAX base stations and 10 WiFi base stations at the central office. The downlink rate of the digital baseband signal based on the EPON protocol is 1.25Gbit / s. After the data frames of 32 ONUs are time-decomposed and multiplexed, the average access rate is about 30Mbit / s. For the radio frequency signals belonging to 10 WiMAX base stations and 10 WiFi base stations, the OLT uses the frequency converter in the radio frequency processing card to assign a specific frequency band to each base station. For example, a transmission frequency band of 2.5 GHz is allocated to No. 1 WiMAX base station, and a transmission frequency band of 6 GHz is allocated to No. 6 WiFi base station. Each frequency band is separated by 0.5GHz, and the transmission bandwidth is allocated for 20 wireless base stations, which req...

Abstract

The invention provides an access terminal OLT device with integration of EPON, WiMAX and WiFi and an access method, and the OLT mainly comprises an EPON data processing card, a radio frequency signal processing card, a frequency multiplexing/demultiplexing module, a light transceiving module and other components. The access with integration of EPON digital baseband signals and WiMAX and WiFi radio frequency signals is completed by utilizing the frequency division multiplexing. The broadband access for regions with service wire resources is mainly carried out by utilizing ADSL, EoC and other technologies through an ONU device of an EPON. The broadband access for the regions which have no service wire resources, but are in complex terrain or a small number of access people and are further incapable of meeting the requirement on the laying cost is carried out by using the WiMa* or WiFi wireless transmission technology. The wireless access technology can also be taken as the emergency communication way for cable access, thereby realizing the seamless coverage of the whole access region. The access terminal OLT device and the access method can provide the high-speed broadband access for all users within the range of 20km, lead the optical fiber broadband access way and the wireless broadband access way to complement each other and achieve the largest coverage range and the optical access efficiency.

Description

technical field [0001] The invention relates to a processing method for integrated access of optical fiber and wireless, in particular to a central office OLT device for realizing integrated access of technologies such as EPON, WiMAX, and WiFi. Background technique [0002] Optical fiber access and wireless access are two cutting-edge technologies in existing broadband access technologies. EPON (Ethernet Passive Optical Network) technology can provide 1.25Gbit / s access for users within a range of 20km bandwidth. WiMAX (World Interoperability for MicrowaveAccess) is a wireless metropolitan area network access technology that can provide 70Mbit / s wireless access bandwidth for users within several kilometers. WiFi (Wireless Fidelity) is a wireless local area network technology that provides users with 11Mbit / s wireless access within a range of 100 meters. Existing manufacturers are all focused on one of the solutions, unable to provide users with a complete solution. Conten...
