每一代的行動通訊技術都會提升一套新的技術與功能來來實現應用的能力，2G是聲音傳輸，3G是數據傳輸，4G是影音傳輸，未來的5G更可以是處理數十億種網路裝置、且能穩定運作的智能網絡。
　　回顧移動通信的發展歷程，每一代移動通信系統都可以通過標誌性能力指標和核心關鍵技術來定義，隨著大量行動裝置及物聯應用，全球網路資料流量不斷暴增，為與萬物相聯的新世界同步，Small Cell小型基地台可改善基本的信號覆蓋和網路容量，進一步整合相關應用服務，支援企業、家庭以及一般用戶，結合網路智能與功能，提供創新服務。
　　現行運用在物聯網大致可分為三個層面：應用、網路、感知，箇中牽涉的行業及面向之大，看似要瞭解物聯網十分困難，不過其實只要掌握發展的基礎建設關鍵，就能夠在網路萬物應用時得心應手。
　　本研究的目的是透過政府推動的智慧型電表基礎建設政策，運用小型基地台的特性打造出快速的基礎建設，並提出一個有效率、降低建置成本，並可節能減碳、綠化環境、減少大型基地台建設，又可維持5G應有的網路速度與使用品質，進而可以順利打造出智慧城市的方法。

　　To a telecommunication company, high quality service and low operating cost are the key to a successful telecommunication business. Long term evolution, marketed as 5G, is a standard for wireless communication of high-speed data for mobile phones and data terminals. Know how wireless systems have evolved over the time and tell the history of Mobile Communications development..
　　5G is a generation currently under development. It denotes the next major phase of mobile telecommunications standards beyond the current 4G/ IMT-advanced standards.
　　To know 5G network requirements as:
• Data rates of several tens of Mb/s should be supported for tens of thousands of users.
• 1 Gbit/s to be offered, simultaneously to tens of workers on the same office floor.
• Several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments.
• Spectral efficiency should be significantly enhanced compared to 4G.
• Coverage should be improved.
• Signalling efficiency enhanced.
• Latency should be significantly reduced compared to LTE

　　This study first know the benefits with small cells. To meet the communication requirements from smart meter, some studies have been investigated for smart meter communications in cellular networks. To minimize the cost of transmission or alternatively transmission time in smart networks. Based on the AMI model of two-tier cellular networks composed of macro cells and small cells, the impact that the user smart meter, the mobility of users and the capacity constraint of the small cell backhaul on the system performance has been evaluated.

　　This Study of the goal is to expand the broadband capability of mobile networks, and to provide specific capabilities for consumers and for various industries and society at large unleashing the potential of the Internet of things.
