Municipal broadband deployments are broadband Internet access services provided either fully or partially by local governments. Common connection technologies include unlicensed wireless (Wi-Fi, wireless mesh networks), licensed wireless (such as WiMAX), and fiber optic cable. Although many cities previously deployed Wi-Fi based solutions, municipal fiber-to-the-home networks are becoming more prominent because of increased demand for modern audio and video applications, which are increasing bandwidth requirements by 40% per annum. ==Wireless public networks== Wireless public municipal broadband networks avoid sometimes unreliable hub and spoke distribution models and use mesh networking instead.〔 This method involves relaying radio signals throughout the whole city via a series of access points or radio transmitters, each of which is connected to at least two other transmitters. Mesh networks provide reliable user connections and are also faster to build and less expensive to run than the hub and spoke configurations. Internet connections can also be secured through the addition of a wireless router to an existing wired connection – a convenient method for Internet access provision in small centralized areas. Although wireless routers are generally reliable, their occasional failure means no Internet availability in that centralized area. This is why companies now use mesh networking in preference to hub and spoke configurations. Three basic models for the operation and funding of Wi-Fi networks have emerged: * Networks designed solely for use by municipal services (fire, police, planners, engineers, libraries, etc.). Municipal funds are used to establish and run the network; * Quasi-public networks for use by both municipal services and private users owned by the municipality but operated for profit by private companies ("private hot spots"). Such networks are funded by specially earmarked tax revenues then operated and maintained on a chargeable basis by private service providers; * Private service providers using public property and rights of way for a fee. These allow for in-kind provision of private access to public rights of way to build-out and maintain private networks with a 'lease payment' or percentage of profits paid to the municipality. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Municipal broadband」の詳細全文を読む スポンサード リンク
