This disclosure describes techniques for cache servers in a content delivery network (CDN) to egress data-intensive content such as videos, multimedia, application packages, etc. to clients by leveraging the broadcast mode of WiFi, which is an open-source modification to standard WiFi that enables transmission of unidirectional, broadcast traffic. The techniques enable the simultaneous transmission of very large amounts of data, e.g., a terabyte or more, in a relatively short time, e.g., one hour, to multiple clients using low-cost, off-the-shelf hardware. In an example application, the described broadcast WiFi techniques can be utilized to update content on public transport vehicles, e.g., buses, trains, cruise ships, airplanes, etc., at a time the vehicles are parked at transit stations, airports, seaports, etc.
