Abstract: Dynamically switching between broadcast and unicast services for service continuity between wireless networks is presented herein. A system can comprise a detection component configured to determine that a mobile device is receiving a broadcast transmission of broadcast data from a broadcast enabled access point device configured to send, via a broadcast service wireless coverage area, the broadcast data to multiple devices via a point-to-multipoint communication protocol. Further, the detection component can detect a movement of the mobile device from the broadcast service wireless coverage area to a unicast service wireless coverage area. A transfer component can initiate, in response to the detection, a unicast transmission of the broadcast data from a unicast enabled access point device to the mobile device—the unicast enabled access point device configured to send, via the unicast service wireless coverage area, the broadcast data to a single device via a point-to-point communication protocol.
