The gain of an omnidirectional WiFi antenna is a key indicator (measured in dBi) that measures its signal enhancement capability, directly affecting the signal coverage range and transmission stability.
Low-gain (3-5dBi) omnidirectional antennas have a wide signal radiation angle, suitable for small spaces (such as bedrooms, small offices). They can evenly cover the surrounding area, avoiding local waste caused by excessive signal concentration.
Medium-gain (6-9dBi) omnidirectional antennas strike a balance between coverage range and signal strength, suitable for medium-sized places (such as living rooms, medium-sized shops). They can penetrate 1-2 non-load-bearing walls and meet the needs of multiple devices connecting to the network simultaneously.
High-gain (10dBi and above) omnidirectional antennas can transmit signals over a longer distance and enhance the ability to capture long-distance signals, suitable for large spaces or scenes with many obstacles (such as factories, large conference rooms). However, attention should be paid to the installation position to avoid unstable close-range signals caused by excessively high gain.
The gain characteristics of omnidirectional antennas allow them to maintain 360-degree signal coverage while flexibly matching gain values according to scenarios, ensuring both the breadth of the signal and the strength of transmission, thus providing precise support for diverse WiFi usage needs.
