The amount of traffic offloaded from smartphones will be 59 percent by 2022, and the amount of traffic offloaded from tablets will be 72 percent. Some have speculated that Wi-Fi offload would be less relevant after 4G networks are in place because of the faster speeds and more abundant bandwidth.
However, so long as data usage caps remain in effect, there will be an incentive for many customers to offload data access to Wi-Fi.
If that remains the case in the 5G era, Wi-Fi offload is going to be higher on 5G networks.
The amount of traffic offloaded from 4G was 57 percent at the end of 2017, and it will be 59 percent by 2022, Cisco estimates. On 5G networks, Wi-Fi offload could be as high as 71 percent, Cisco estimates.
The amount of traffic offloaded from 3G will be 40 percent by 2022, and the amount of traffic offloaded from 2G will be 30 percent.
“As 5G is being introduced, while we expect plans to be generous with data caps and speeds will be higher than ever, the new application demands on 5G are also going to move upwards as well encouraging similar behaviors of offload as 4G,” Cisco believes.
Also, the fixed network will continue to supply most of the actual consumed bandwidth, as much as 80 percent, in 2022, Cisco estimates.
The offload percentage on 5G is estimated to be 71 percent by 2022. However, as the 5G network matures, we may see offload rates come down, Cisco says.
