Cat. 4, Cat. 6, and now Cat. 10. These chipmakers are really pushing the cellular capabilities of their products to the limits, perhaps even faster than networks can actually adopt these network speeds. Of course, that has never been a reason for the likes of Qualcomm and Samsung to take it easy. Following the mobile chip leader's footsteps, Samsung is now said to also have an Exynos ready next year that will achieve speeds of 450 Mbps on downlink, almost twice as fast as Cat. 6's 300 Mbps.
