Juniper Research projects that global roaming data traffic from 5G subscribers will increase from 2.6 PB in 2021 to 770 PB by 2026. This represents enough data to stream 115 million hours of 4K video from platforms like Netflix. The report predicts that, as 5G roaming proliferates, vendor competition around the 5G-enabled roaming services mentioned above will intensify. Subscribers will expect comparable levels of bandwidth and latency when roaming over 5G to home network connectivity, and roaming vendors must accommodate this demand via value-added services.
