本論文提出一智慧家庭網路「Gigabit網路架構」，結合光通訊G-PON技術與同軸電纜（Coaxial Cable）網路MoCA技術成為異質網路，提昇現有頻寬100Mbit/s至Gigabit，共同建構智慧家庭網路（家庭骨幹網路），進而迎接政府推動數位匯流產業發展；另外本論文提出智慧家庭骨幹網路建置重要性，使得家庭電信（電話）、網路、廣播電視融合為一網路傳輸管道。更進一步，家庭影像監控、家電控制甚至異地檔案傳輸同時享有Gigabit網路帶來的效益。

首先針對目前家庭網路上網還是停留在低流量、低傳輸速率（100Mbit/s）的電腦與手機連網現況進行分析，並觀察近年來網路技術推波助瀾下，本論文提出光纖與同軸異質網路整合概念，即Fiber-to-the-Home（FTTH）G-PON網路架構，藉由G-PON上網可達Gigabit速率來達成Internet WAN需求；另外在家庭骨幹網路由同軸電纜MoCA通訊做為提供穩且不易受干擾的傳輸媒介，達到家庭每一個房間都有穩定的寬頻上網與高解析影像傳輸通道。

本論文以G-PON與MoCA兩種技術做為傳輸媒介，透過硬體設計與量測分析、網路整合測試來探討如何建構智慧家庭Gigabit網路。研究中對於硬體高速訊號設計與EMI/EMC處理做一探討，此外透過乙太網路（Ethernet）硬體測試對於1000Base-T Gigabit網路量測達成穩定網路橋接傳輸媒介，最後對於整合測試簡化分析做完整討論。

實驗結果顯示，本論文所提出智慧家庭Gigabit網路是一個兼顧成本與現有技術且具前瞻性高速家庭網路架構，基於本研究所提出光纖與同軸異質網路硬體設計之架構可達到穩定Gigabit傳輸目標，對於未來10年數位匯流趨勢貢獻一己之力。

This paper presents a smart home network gigabit network infrastructure, which combines G-PON (Gigabit-Capable PON) optical fiber communications with MoCA (Multimedia over Coax Alliance) coaxial cable technology to form a heterogeneous network and enhance the existing bandwidth of 100Mbit/s to gigabit/s. The network integration allows to build a smart home network (or family backbone network) to meet the government policy of digital convergence plan. In addition, the paper addresses the importance of building smart home backbone networks so that telecommunications (voice), Internet, radio, and television can be integrated into a transmission network in the residential area. Furthermore, home video surveillance, remote appliance control, and even file transfers can benefit from the gigabit transmission networks.

This thesis first reviews current home networks, Internet, and mobile networks that are mostly operated at relatively low transmission rate (100Mbit/s). The concept of heterogeneous integration of both optical and coaxial networks is discussed. The integrated network uses the Fiber-to-the-Home (FTTH) based on G-PON network architecture to gain access of up to giga bit-rate to reach Internet WAN and MoCA, which serves as the backbone network with a stable transmission media. The family rooms can also connect to the broadband Internet access and high-resolution video transmission channels.

In this work, both G-PON and MoCA technologies are used as the transmission medium to build a smart home gigabit network. The feasibility is evaluated by hardware design, hardware measurement and system integration tests. Moreover, the study showed how to deal with EMI/EMC issues with high-speed signal design and achieved the goal of a stable bridge mode network media design with 1000Base-T Gigabit Ethernet analysis.

Experimental results show that a smart home gigabit network infrastructure proposed in this paper is a cost effective and prospective high-speed network with currently available technology. The proposed approach meets the gigabit transmission target based on the optical and coaxial heterogeneous networks hardware design.
