It is a concern for Wifi links.

IEEE 802.11ai addresses challenges where a large number of mobile users 
are continually entering and leaving an existing extended service set 
(ESS) coverage area. The amendment provides scalability for a high 
number of users simultaneously entering an ESS, minimizes time spent 
initializing a link, and provides secure authentication. In effect, IEEE 
802.11ai significantly improves user connectivity in high-density 
environments, such as arenas, stadiums, airports, shopping malls, etc., 
as well as for automotive systems, allowing for a more secure and 
reliable connection, and enabling more efficient spectrum use by 
optimizing the protocol overhead in high-density user environments.
