In wireless networks, mobile users connect either with other devices or with base stations. They can experience high errors caused by losses, low levels of signals or disconnections. Due to these aspects, it is important to find ways to make the communication reliable. Product network codes represent a way to improve error-correction capability. The main idea is to use a powerful error correction code in time with random linear network coding in space domain. This paper analyses the error-correcting capabilities of product network codes composed by either Luby transform (LT) codes or Reed-Solomon (RS) codes, and RLNC. The kind of errors are burst errors. The results quantify how product network codes improve reliability in case of high burst error probability.
