Wireless Point to Point links
In fixed outdoor wireless communications there are two primary deployment methods used for distributing wireless: Point-to-Point (PtP), and Point-to-Multipoint (PtMP).
Point-to-Point (PtP): Connects two locations, usually multiple km, essentially forming an Ethernet bridge.
Point-to-Multipoint links (PtMP): Connects three or more locations, using one Base Station (or Access Point) and multiple CPE devices (Stations) connected to the Access Point.
PtMP performance depends on both sides of the link, i.e. if you want to reach long distances, you must choose the right Base Station AND the right CPE for each case.
Base Station Usually located on the top of a tower, building or mast. The height will determine maximum coverage. When planning the Base Station, it's usually ideal to plan for an antenna with the smallest coverage that still covers the desired area. Antennas with a wider beamwidth, covering a wider zone reaching more stations, may be more susceptible to interference, resulting in decreased scalability and performance.
