    • The present invention uses data from several sources to determine lines-of-sight between nodes in a FSO network. The present invention provides a three-dimensional neighborhood modeling system that uses aerial image data, Digital Elevation Models, U.S. street map data and address data to automatically map the placement of nodes within a neighborhood or other geographical area. Method for creating the 3-Dimensional, House and Tree Maps used in the line-of-sight processing are also disclosed. A House Map in the present invention identifies houses in an area of consideration, and a Tree Map in the present invention identifies trees in an area of consideration. A 3-Dimensional Map in the present invention provides an elevation for every pixel for the area under consideration, whereby the elevation is adjusted for the height of trees, houses and other objects.
    • 本发明使用来自多个源的数据来确定FSO网络中的节点之间的视距。 本发明提供一种三维邻域建模系统,其使用空中图像数据,数字高程模型,美国街道地图数据和地址数据来自动映射邻域或其他地理区域内的节点的位置。用于创建三维 在视线处理中使用的House和Tree Maps也被公开。 本发明中的房屋地图识别考虑区域中的房屋,并且本发明中的树形图识别考虑区域中的树木。 本发明的三维图提供了所考虑的区域的每个像素的高度,由此根据树木,房屋和其他物体的高度来调节高度。

    • A digital data network (100) uses network nodes (106) incorporating infrared transceivers (108). Each node (106) includes a plurality of infrared transceivers (108) having transmitter (109) and receiver (111) optics designed to facilitate line-of-sight infrared optical communications in a residential or business neighborhood. New nodes (106) are installed with at least one selected transceiver (108) having line-of-sight access to at least one existing transceiver (108). Automated tracking (370, 400, 500) and acquisition (300) processes are used to align transceivers (108) to enable data communication and to acquire newly installed nodes (108) into the network (100). Other automated tracking programs operate on an as-needed or scheduled basis to maintain good alignment and communications between adjoining node transceivers (108). Network nodes include weather-proof housings (112) and are of a size and shape to be easily mounted on existing structures so as not to disrupt the visual appeal of a neighborhood.
    • 数字数据网络(100)使用并入有红外收发器(108)的网络节点(106)。 每个节点(106)包括多个具有发射器(109)和接收器(111)的红外收发器(108),该光学器件被设计成便于住宅或商业邻域的视线红外光通信。 新节点(106)安装有至少一个选择的收发器(108),其具有至少一个现有收发器(108)的视线访问。 使用自动跟踪(370,400,500)和采集(300)进程来对齐收发器(108)以启用数据通信并且将新安装的节点(108)获取到网络(100)中。 其他自动跟踪程序按照需要或调度的方式运行,以保持相邻节点收发器(108)之间良好的对准和通信。 网络节点包括耐候性壳体(112),并且具有容易安装在现有结构上的尺寸和形状,以便不会扰乱邻域的视觉吸引力。
