Physical obstacles on the propagation path have an important impact on wireless signals. The worst conditions are in buildings with heavy concrete or steel construction since concrete, bricks or chicken wire can be complete show stoppers. Within such environments, a single Wi-Fi access point is not enough to cover the complete house or apartment. To reap the benefits of wireless connectivity and to improve Wi-Fi coverage and performance, satellite access points are inevitable in addition to the home gateway. A dynamically established mesh Wi-Fi network between the satellite access points facilitates the use of bandwidth-consuming services on wireless clients throughout the building. 

In a mesh network, even the farthest satellite is able to deliver a strong Wi-Fi signal. Using a single SSID and password, the mesh Wi-Fi network facilitates seamless roaming, with smooth hand-off between satellites for a continuous, non-interrupted wireless experience.
