Hình 10-2 lai tích hợp sóng milimet, chất xơ, và không dây truy cập dữ liệu quang học và các kịch bản hệ thống phân phối. Thực hiện tùy chọn cho HFR tích hợp picocell truy cập và hệ thống phân phối cho các môi trường nội thành và các tùy chọn kết nối. | Chapter 10 Designing Millimeter-Wave Devices 273 Figure 10-2 Integrated hybrid millimeter-wave fiber and optical wireless data access and distribution system scenarios. Implementation options for integrated HFR for picocell access and distribution systems for inner city environments and interconnection options. Note The World Trade Center towers in New York City are shown in this figure to remember those who died in the terrorist attack of September 11 2001. Picocell redistribution outdoor and or indoor by wireless fiber or coax The possibility of using the existing embedded fibers to the curb and neighborhood as well as FSOW tandem links permits broadband backbone network integration and combined services through a single shared infrastructure leading to faster deployment and lower system cost for service providers. Network Operation Center A consolidated network operation center NOC for end-to-end network management and control is implemented to relocate the conventional base station control and switching facilities into the NOC to perform the required switching routing and service-mixing-function operations. The integration and merging of multiband HFR FSOW and digital fiberoptic technologies at the NOC with fixed BWA has provided flexible and unified network operation as well as the possibility of end-to-end network management and control. The consolidation will benefit through lower infrastructure complexity and cost resulting in a more reliable and centralized database and operations. 274 Part 2 Planning and Designing Data Applications Portable Broadband Wireless Data Bridge and Access Node This chapter will now discuss the concept and realization of a portable wireless data access node for a bidirectional ATM-based connection to reach a fixed broadband fiber network. The goal of this effort is to demonstrate the feasibility of a rapidly deployed access node and backbone interconnection to the NOC for application in specialized scenarios such as military .
