What does "LPI" mean?
Table of Contents
Low Power Indoor (LPI) refers to rules set by the Federal Communications Commission (FCC) for wireless communication within buildings. These rules allow devices, like Wi-Fi routers, to operate using small amounts of power. This is important because it helps manage shared use of radio frequency bands, particularly in crowded areas.
Purpose of LPI
The main goal of LPI is to enable wireless devices to connect indoors without causing interference to other important communication systems outside, like fixed links. By keeping power levels low, the chance of causing problems for these systems is reduced.
Benefits of LPI
- Efficient Use of Space: LPI allows more devices to operate in the same area without disrupting each other.
- Accessibility: It enables easier access to wireless networks indoors, improving internet connectivity for users.
- Protection of Existing Users: By limiting power, LPI helps protect established communication systems from interference.
Current Situation
As more Wi-Fi devices using LPI rules are installed, research is ongoing to ensure they work well without disturbing fixed communication lines. Some recent measurements show that the risk of interference is low, but further studies are planned to confirm this and find the best settings for these devices.
