Connect Multiple Base Stations

Wi-Fi was once described as reaching “only” about 150 feet, which is a rough estimate of the radius of older 802.11b and g devices; with 802.11n and ac, the distance is sometimes cited as longer, or just as “farther,” because it’s impossible to characterize with any precision how Wi-Fi signals will pass through any arbitrary house, office, café, airport, or store. Also, range measured as a linear dimension misstates the problem of volume, the three-dimensional space to fill.

But you can extend the covered volume by adding more base stations with overlapping signals. As a Wi-Fi adapter in a device moves across overlapping regions, it can automatically switch base stations while maintaining a network connection. ...
