Multi-connectivity offers diversity in terms of multiple interfaces through\nwhich the data can be sent, thereby improving simultaneously the overall\nreliability and latency. This makes interface diversity a natural candidate for\nsupporting Ultra-Reliable Low Latency Communications (URLLC). This work\ninvestigates how the packet error statistics from different interfaces impacts\nthe overall reliability-latency characteristics. We use the simple\nGilbert-Elliott model for burst errors and estimate its parameters based on\nexperimental measurement traces from LTE and Wi-Fi packet transmissions\ncollected over several days. The results show that using interface diversity\nconfigurations that include at least one Wi-Fi interface leads to, somewhat\nsurprisingly, since Wi-Fi is generally less reliable than LTE, superior results\nin terms of packet success and error burst duration. Another interesting\nfinding is that Wi-Fi-based interface diversity configurations outperform\neven ultra-reliable single links.\n
