Wi-Fi Offloading Solution for Carriers: Speedify Combines Wi-Fi and Cellular Without Dropping Calls

Mobile Data Offloading from 4G to WiFi Done Easy

Wi-Fi offloading keeps coming back onto carrier roadmaps and keeps stalling in the same place. Subscribers on unlimited plans have no reason to switch to Wi-Fi themselves, and every automatic handover costs them a stalled download or a dropped call.

Speedify is software that combines cellular and Wi-Fi into one connection, so offloading happens without a handover for the subscriber to notice, which removes the reason subscribers resist it. With only one of those connections, Speedify works as an encrypted VPN and cannot stop that connection from dropping.

With Speedify, your internet stays on when one connection fails.

This post covers why subscribers stopped offloading on their own, and what unlimited data plans do to a 4G network without it.

What Wi-Fi Offloading Is and Why Subscribers Stopped Doing It

Wi-Fi offloading means carrying a subscriber’s traffic over Wi-Fi instead of the cellular network whenever Wi-Fi is available, which frees cellular capacity for everyone else. For years, subscribers did much of it themselves.

Because of high data fees, consumers used to have the incentive to stay on Wi-Fi as much as possible. This desire to self-manage offloading led to an explosion of public Wi-Fi networks. This further reduced the need for carriers to worry about Wi-Fi offloading themselves.

Competition between carriers then lowered the price of data, so many subscribers had less reason to manage offloading themselves, and several major carriers began offering unlimited data plans.

These unlimited plans remove any incentive for consumers to move their data from cellular to Wi-Fi on their own.

Unlimited Data Plans Push More Traffic onto 4G and 5G Networks

Without a reason to offload on their own, subscribers keep their traffic on cellular, and carriers are back to too much expensive data and too little bandwidth. The more popular unlimited plans become, the more of that load lands on the cellular network at busy times.

When congestion shows up as network errors and slow page loads, subscribers on unlimited plans blame the carrier, and some of them leave.

The New Wi-Fi Offloading is About Gapless Aggregation

The best way for carriers to handle Wi-Fi offloading is to improve the customer experience with gapless aggregation. Speedify’s proprietary protocol makes gapless aggregation easy.

Speedify runs in the background and manages the phone’s connection. With cellular set to a lower priority than Wi-Fi, Speedify sends traffic over Wi-Fi whenever Wi-Fi can carry it, while keeping the phone connected to Wi-Fi and cellular at the same time. If the Wi-Fi fails or the subscriber walks out of range, traffic continues over cellular on the same session until another Wi-Fi network is available.

Speedify keeps customers connected across Wi-Fi and cellular and helps carriers handle Wi-Fi offloading automatically. Carriers don’t need to spend money on research and development, because the Speedify protocol is ready to license and build into a carrier app.
