5G Wi-Fi Offload Training

Wi-Fi offloading is a technique used by wireless carriers to basically reduce usage of their cellular networks by having you use your home or free local Wi-Fi hotspots for your smartphone’s data connection.

It’s expected that 5G services will be handing-off connections to Wi-Fi networks at a staggering pace. The reason is because in all likelihood cellular providers won’t be able to keep up with user’s bandwidth demands, forcing them to embrace Wi-Fi network offloading, which is more commonly referred to as Hotspot 2.0 or Passpoint.

It was once widely believed that Wi-Fi would disappear with the emergence of the “do everything” architecture of 5G. But that has not been the case. Wi-Fi, especially for Mobile Virtual Network Operators (MVNOs), has become an adjunct to 5G operations, especially in the area of offloading.

Offloading reduces the amount of data being carried on the cellular bands, freeing bandwidth for other users. It is also used in situations where local cell reception may be poor, allowing the user to connect via wired services with better connectivity.

More than 60% of data connections are happening on Wi-Fi, and this number is expected to increase. Operators are incorporating Wi-Fi as part of their 5G strategy for several reasons including the fact that Wi-Fi already provides near ubiquitous coverage at a fraction of the cost of 5G deployments.

Consequently, software is now showing up that allows operators to use an on-device connectivity manager to enforce an always-best connected policy and to bridge the divide between consumer demand and network availability.

Besides saving money for operators, some of the other advantages of Wi-Fi data offloading are:

  • It reduces the amount of data being carried on the cellular bands, thereby, freeing bandwidth for other users.
  • It caters to the growing mobile data demand and smart devices usage patterns that have the characteristics of short sessions, high throughput and low latency.
  • Offloading enhances the end-user experience by improving service capacity and capability. The end user devices are so designed that they perform better with faster data speeds in Wi-Fi networks, using cellular broadband, which is more affordable for indoor services. This reduces the operating expenditure of service providers when compared to Wi-Fi.

Another aspect of Wi-Fi offloading is Licensed Assisted Access (LAA), which was introduced in the 3GPP release 13 as part of LTE Advanced Pro. LAA gives a performance boost to smartphone users, while optimizing available wireless network resources for all users.

LAA is a variant of the controversial LTE-Unlicensed (LTE-U), which augments a carrier’s LTE service by utilizing the unlicensed spectrum in the 5GHz range. LTE-U is an extension of the LTE wireless standard intended to allow cellular network operators to offload some of their data traffic by accessing the unlicensed 5 GHz frequency band.

Unfortunately, Wi-Fi attacks via offloading are the most pressing security risk to 5G users.
