Global Wi-Fi Offload Traffic Forecast, 2014 - 2019: An Alternative to LTE

Most mobile operators around the world are experimenting with Wi-Fi networks in some way. AT&T in the U.S., for example, has rolled out Wi-Fi hotzones in congested metro areas. SK Telekom offloads a massive amount of data traffic each month to Wi-Fi, as do NTT DoCoMo and Softbank in Japan. However, in the Middle East and Africa Wi-Fi networks are really just getting started. Wi-Fi is a little more advanced in Latin America, depending on the country, but deployments still lag those in more mature wireless markets.

The reasons behind regional differences in Wi-Fi deployments are as much due to differences in GDP, regulation and taxation, as they are to availability of licensed cellular spectrum, affordability of devices relative to median income, reliable access to power, literacy levels, population and population densities.

This report presents iGR's model for Wi-Fi Offload, which include:

1. Wi-Fi Only: This is data traffic that occurs on a Wi-Fi network outside of the home or office on Wi-Fi-only devices.

2. Wi-Fi Offload (User Driven): A subscriber/end user who chooses a Wi-Fi connection (except one inside the home or office) rather than use their 3G/4G mobile broadband connection. If the non-home/non-work Wi-Fi network did not exist, this traffic would have gone over the mobile operator’s cellular data network.

3. Wi-Fi Offload (Carrier Driven): This is user-generated data traffic that the operator diverts from its 3G/4G RAN to a carrier-managed Wi-Fi network. This is data the subscriber would have used regardless of the type of RAN they are on (Wi-Fi or cellular). This type of Wi-Fi offload is not widespread today, but iGR believes it will become more common over time.
