Abstract
A system and method for communicating real time information using a wide area network protocol and communications protocol that mitigates against potentially significant packet loss rates caused by events such as signal blockage occurring at the underlying wireless transmission (e.g., radio) links. In one implementation the method involves creating a first data packet having a first segment of information, and a first identification (ID) code. The first data packet is then transmitted. A second data packet is then created having information forming the first data packet and also a second segment of information identified by a second code. The second packet is then transmitted. Subsequently formed data packets may include all of the information from previously created data packets until a maximum packet depth is reached, and then each subsequently created new data packet drops off the oldest packet information from the previously created packet while including new information.
