What is RF POI?

RF POI stands for RF Point of Interface, which is a telecommunications device that combines and distributes multiple radio frequency (RF) signals from different network operators or systems without interference. It works by filtering and synthesizing signals from various sources, such as different operators’ base stations, into a single, combined signal for an indoor coverage system. Its purpose is to enable different networks to share the same indoor infrastructure, reducing costs and complexity while ensuring reliable signal delivery for multiple services like cellular, LTE, and private trunking communications.

How it works

• Uplink: It collects signals from mobile phones within an area and sends them to the respective base stations after filtering and separating them by frequency and operator.
• Downlink: It synthesizes signals from multiple operators and frequency bands and combines them into a single signal to be distributed throughout the building or area.
• Interference prevention: The POI uses advanced filters and combiners to separate and manage signals, preventing interference between different operators’ networks.
