A Point-to-Multi-Point (P2MP) link is a type of wireless communication link where a single transmitter communicates with multiple receivers. Here are the simple basics:
# Key Components
1. Base Station (BS): The central transmitter that communicates with multiple receivers.
2. Subscriber Stations or Subscriber Module: The receivers that communicate with the base station.
# How it Works
1. Downlink: The base station transmits data to multiple subscriber stations.
2. Uplink: Each subscriber station transmits data back to the base station.
# Advantages
1. Cost-Effective: P2MP links can be more cost-effective than point-to-point links for connecting multiple locations.
2. Scalability: P2MP links can support multiple subscribers, making it easy to add new users.
3. Flexibility: P2MP links can be used for various applications, such as broadband internet, voice, and video.
# Applications
1. Wireless Broadband: P2MP links are used to provide wireless broadband internet access to multiple locations.
2. Cellular Networks: P2MP links are used in cellular networks to connect multiple cell towers to a central base station.
3. Fixed Wireless Access: P2MP links are used to provide fixed wireless access to homes and businesses.
Some radios that support P2MP are: Cambium, Ubiquiti, Cambridge, Mimosa etc.
