What Is Mobile Data Offloading? How Speedify Does It

Mobile data offloading frees up bandwidth by moving traffic to Wi-Fi networks

Mobile data offloading means routing subscriber traffic away from the cellular network and onto Wi-Fi, which is cheaper to carry and often faster. The catch is the handover: the moment a device switches networks, downloads stall and calls drop.

Speedify is software that bonds Wi-Fi and cellular at the same time instead of choosing between them, so traffic shifts onto Wi-Fi gradually and nothing restarts.

Find out why offloading matters so much to operators, and how bonding saves an MVNO money while improving what the customer experiences.

Why is Mobile data offloading such a big deal?

Carriers and MVNOs have known about a looming crisis for years. As mobile devices have become more powerful and sophisticated they have also become more popular resulting in overwhelming demand for higher bandwidth. It is imperative now that network operators employ strategies to reduce the load on their core cellular networks by leveraging existing investments in wired and wifi infrastructure.

Up until this point however, it has been impossible for network operators to utilize mobile data offloading tactics without negatively affecting the customer experience. Some of the obstacles include:

  • iOS and Android devices are unable to tell when a hotspot is “dead” or not functioning properly
  • Manually switching between networks is time consuming and cumbersome
  • Consumers end up with interrupted internet access during network changeovers
  • Consumer concern about hotspot security

The Speedify link aggregation solution helps network operators and hardware manufacturers make use of Speedify’s revolutionary channel bonding technology to seamlessly switch between Internet connections providing increased QoE while reducing LTE usage.

Mobile Data Offloading Using Speedify Saves MVNOs money and Improves the Customer’s Internet Experience

Speedify is a complete solution to channel bonding and Wi-Fi offloading issues on mobile devices. It can be built into existing iOS, Android, Windows, and MacOS software and runs in the background monitoring and improving network performance for all the apps on the device. The Speedify channel bonding technology is cost aware and uses policy based routing that can be configured for increased speed or reduced cellular usage. Optional VPN encryption means that Speedify can also keep users secure across public Wi-Fi networks.

Currently, when a consumer connects to a dead hotspot, the device does not automatically fall back to using LTE. Instead, the consumer is stranded without any internet connection. This creates a poor user experience and discourages future use of hotspots. Speedify eliminates this problem.
