Point-to-Multipoint Communication (PMP)
Definition - What does Point-to-Multipoint Communication (PMP) mean?
PMP is usually used for establishing private enterprise connectivity to offices in remote locations, long-range wireless backhaul solutions for various sites, and last-mile broadband access. As such, it is widely used in IP telephony and wireless Internet by means of gigahertz radio frequencies. These PMP networks are employed in distribution amenities, huge corporate campuses, school districts, public safety applications, etc.
Techopedia explains Point-to-Multipoint Communication (PMP)
A point-to-multipoint network can be easily deployed when compared to the deployment of a point-to-point network because the equipment has to be deployed only at the new subscriber's site. The only condition is that all the remote sites must come within the visibility and range of the base station. Hills, trees and other kinds of obstructions make point-to-multipoint nods unsuitable for office and residential coverage.
PMP systems are categorized into single system and bi-directional systems. A point-to-multipoint network is suitable for either customers or backhaul operations that are in need of a high-speed, reliable connection, but worried about paying for unused dedicated capacity. The drawback of point-to-multipoint node topology is its inability to interconnect with other nodes because of the directional antenna.
