Spectrum sharing matters because communications spectrum is a scarce asset, and demand is growing very fast, both because billions of new Internet access users will come online, and because new Internet apps and devices consume vastly more bandwidth.
Spectrum sharing martters, in large markets, because there is, for example, almost no uncommitted communications spectrum available in the sub-2-GHz range.
Though there is an expectation that much spectrum in millimeter bands (3 GHz to 300 GHz) can be allocated for communications purposes, most of that spectrum will be severely “short range,” and hence best suited for indoor or small cell applications.
Global mobile data traffic grew 69 percent in 2014, and each succeeding mobile generation seems to grow consumption by an order of magnitude, according to Cisco estimates. Long Term Evolution (4G) devices consume an order of magnitude more data than a non-LTE device, for example.
Any smartphone tends to lead to consumption of 37 times the data of a feature phone, according to Cisco. And smartphones are becoming the standard global device. Where today 28 percent of customers use smartphones, that will grow to perhaps 52 percentby 2018.
Use of Internet access plans might reach 84 percent by 2020, according to Ericsson.
You can see where this is going. Younger users text more than they talk, and though today's users 25 and above still talk more than they text, the usage pattern is uniform: younger age cohorts text more than older age cohorts.
So as each age cohort advances, one might predict that texting behavior will grow over time. How much it grows is the only real question.
Users 18 or younger actually"talk" about as much as users 55 to 64. One suspects an awful lot of "voice" activity is of the coordination and collaboration sort, so that younger and mid-life workers might be in work groups that require more coordination than workers 55 to 64.
Korea Telecom, like Verizon, now sees different strategic value for the fixed network. AT&T likely agrees, up to a point. The stated upside for Korea Telecom fixed transport network capacity upgrades is said to be “home video, mobile broadband, and VIP leased lines.” Consumer video includes support for bandwidth-intensive 4K video formats, but telco upgrades to fiber-to-home or fiber-to-node long have been premised on incremental video entertainment revenues. That is not especially new. Nor would anyone find trunking network support for business and enterprise customers too surprising. What is different is the use of the fixed network as backhaul for mobile broadband. Again, while mobile backhaul always has been key revenue driver for cell tower connections, coming small cell requirements represent a qualitative change. It is one thing to support networks of macrocells. That fiber-to-tower market has been important for many service providers for some years. Up to this point, in the…
easonable people will differ about the value of changing the definition of broadband from time to time. When definitions are changed, though, it becomes more difficult to track progress, even if higher minimum definitions are indirect proof that speeds are increasing, across the board. Three decades ago, in the U.S. market, “broadband” was, by definition, any speed faster than 1.5 Mbps. A decade and a half ago, fiber to the home meant symmetrical 10 Mbps speeds. These days, anything below 25 Mbps is not even “broadband.” Someday, even 100 Mbps might not be considered “broadband.” It just depends on adoption of speeds in the gigabit range, on both fixed and mobile networks. source: Arris
