Question 7 5G Networks (10pt)

Enhanced internet quality and the rise of 5G

Just as the amount of data generated and stored around the world is poised to grow tremendously in 2018, consumers will also expect better and faster connections from network providers. Qualcomm Snapdragon has been spearheading the move to faster network speeds, and 2018 should see an increase in the number of groups working on these improvements. As this work gains momentum, we anticipate strong movement from gigabyte LTE speeds to full 5G networks, helping us reach 5G capabilities in record time.

Enhanced network quality will increase consumer expectations for highly-responsive, fast-loading services and apps. Savvy business owners will move quickly to reevaluate and upgrade their SaaS, PaaS, and website platforms to be more responsive. The IoT and IoE industries will also benefit from faster network speeds by allowing organizations in this space to receive and deliver data more efficiently in real time.
