After each interval, the wireless devices report information about the wireless device's reception of the portion of the file sent during the preceding interval. If the number of wireless devices that received erroneous file fragments is higher than some threshold, the number of times each packet is redundantly transmitted is increased for the multicasting of another portion of the file to be sent during another interval."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multicast file delivery","description":"The process of multicasting a file to a group of wireless devices is divided into a number of time intervals of roughly equal duration.
