International Wi-Fi roaming extends Wi-Fi access to subscribers when they are traveling outside of their communications service providers (CSPs) home network. International travelers spend a significant amount of money to gain access to Wi-Fi hotspots when abroad. There are a number of reasons for CSPs to adopt Wi-Fi as part of their international roaming strategy, but three stand out above the rest: retain and increase wallet share in the high-value customer segment; monetize the opportunity around Wi-Fi-only devices; and take advantage of Wi-Fi to increase the profitability of cellular data roaming.
