Cellular networks are a critical infrastructure supporting applications in all domains we may think of, ranging from e-commerce, transportation/mobility, and education to eHealth/personal well-being, and manufacturing. Cellular networks will be a key infrastructure for Internet of Things devices, and, indeed, the vision is that next-generation cellular networks will be more about devices than people. In other words, the goal of next-gen cellular networks is to be “sensing networks.”
However, even without looking into what next-gen cellular networks will be, it’s clear that technologies for cellular networks have made major advances in the past few years. Fourth Generation Long-Term Evolution (4G LTE) technology has increased the bandwidth available for smartphones, in essence delivering broadband capacity.
