The coverage of the EzHotspot Extender depends on several environment factors such as distance, obstacles and other wireless noise interference.
In an indoor environment, a single Ezhotspot Extender is sufficient to cover 3 floors and across 4~5 adjacent rooms, provided there is no other wireless noise interference.
In an outdoor environment, a single Ezhotspot Extender can repeat another remote wireless network or hotspot up to a distance of 250 meters, provided there is complete line of sight, without obstacles and no other wireless noise interference.
As a general guide, when you have intermittent or weak wireless connection on a smartphone, tablet or latop in a particular location. The EzHotspot Extender placed at the same location will improve the wireless signal coverage by 99%.
