5G Wi-Fi Offload Training

5G Wi-Fi Offload Training

5G Wi-Fi offloading is all about relieving the congested mobile data networks with additional capacity from unlicensed Wi-Fi spectrum.

Analysts agree that as the industry moves toward 5G, Wi-Fi becomes more important, not less important. Wi-Fi already provides near ubiquitous coverage, 5G performance for both speed and capacity densities, at a fraction of the cost of 5G deployments.

Consequently, the popular opinion is that operators must incorporate Wi-Fi offloading as part of their 5G strategy.

Several technologies have emerged recently that involve cellular data traffic offloading to Wi-Fi, however, LTE-Unlicensed (LTE-U) and License-Assisted Access (LAA) are the most notable.

LTE-U performs adaptive duty cycling with Carrier Sense Adaptive Transmission (CSAT), and adapts according to the Wi-Fi traffic load. But it does not perform Listen Before Talk (LBT).

LAA on the other hand does perform LBT, hence, it is considered to be better in maintaining fairness with Wi-Fi devices. Both LTE-U and LAA operate in 5GHz band and have been standardized in 3GPP Rel-12 and Rel-14 respectively.

The general belief is that offloading to Wi-Fi is a more affordable way to connect and, when managed correctly, provides better connection experiences.

Industry experts believe that in the 5G era, Wi-Fi uploading is essential given the penetration issues of 5G’s mmWaves. Instead of rolling out expensive indoor 5G solutions to expand coverage, deploying Wi-Fi access points for mobile offload is a forgone conclusion. This is where WiFi 6 technology shines to complement the 5G vision.

With many countries pushing their Smart City and Internet of Things (IoT) initiatives, 5G Wi-Fi offloading is receiving serious attention.

That’s because it is vital to have excellent connectivity to achieve these goals. Machine-to-machine communications will grow exponentially, as will personal telecommunications for work or leisure. For example, machines in smart factories, healthcare monitoring solutions, autonomous vehicles, and smart home devices need uninterrupted connectivity for a seamless workflow.

Even though daily Wi-Fi session times are a fraction of daily cellular session times, the amount of data transferred during Wi-Fi sessions far outpaces the amount transferred during cellular sessions.
