As mobile traffic surpassed wire traffic in the fall of 2014, the infrastructure behind public Wi-Fi is becoming less efficient and more costly to deploy. With an increasing number of mobile devices using Wi-Fi as their main Internet connection and with users choosing Wi-Fi as soon as it is available, the traditional Wi-Fi limits are soon reached.
The installation and use of a traditional Wi-Fi infrastructure in high mobile traffic areas are hindered by the following limitations:
• The difficulty of creating an efficient plan to install access points;
• Overrun channels due to too many users connected to the same access point;
• An ever-changing mobile access point;
• The complexity of access point management by the WLAN controller.
For these reasons, the quality of the signal, uncertain to begin with, is greatly affected by interferences.
However, things are changing thanks to new technologies like Smart Wi-Fi.
