Point-to-Point Wireless Links
Point-to-point wireless (also called P2P) is the simplest network architecture you can set up in order to connect two locations using a wireless radio link.
Point-to-point wireless links can go from a short-range link connecting two locations just a few hundred feet apart to a long range point-to-point wireless link that connects two locations tens of miles away from each other. In a point to-point-wireless link, distance is affected by the height of each Ethernet radio device, the frequency used, the power level, and environmental interference.
Point-to-Multipoint (also called star topology or simply P2MP) is a common network architecture for outdoor wireless networks to connect multiple locations to one single central location. In a point-to-multipoint wireless Ethernet network, all remote locations do not communicate directly with each other but have a single connection towards the center of the star network where one or more base station is typically located.
Outdoor point-to-multipoint wireless solutions are very common both for wireless Internet service providers (WISPs) and for outdoor video-surveillance systems. In a WISP network, subscribers are connected at the edge of the network using a client device typically mounted on the roof of their house. One or more central base stations are mounted on a high building, or on a mountaintop or on a water tower in line of sight with as many client devices as possible.
In outdoor wireless video-surveillance systems, each camera in the field is connected to a wireless client device and then a base station is mounted on top of a tall building and acts as the central device and coordinator of the point-to-multipoint wireless network. In a point-to- multipoint wireless CCTV system, all video streams from the remote cameras are collected at this central location at the center of the point-to-multipoint wireless system and then transmitted to a control room using a point-to-point wireless or fiber backhaul.
