5G is coming — and with it, potentially, some enormous changes in how service is delivered. For decades, the gold standard of cyberspace service has been fiber optic cable (then-called cobweb-to-the-dwelling house, or FTTH). Dreams of a nationwide wired network delivering gigabit or greater speeds, still, have been stymied by steep costs and, to some extent, by relentless political campaigns by the ISPs themselves to ban municipal broadband and entrench their own monopolies. 5G's rollout isn't going to practice anything to modify the latter issue, but ISPs are salivating over the thought of the erstwhile.

Verizon, for example, has appear a new service for its 5G customers rolling out in four cities: Los Angeles, Sacramento, Houston, and Indianapolis. Sign upwardly for the company'south service, and you'll become a free Apple tree TV ($179) and a subscription to YouTube TV, at $40 per month. Instead of a wired connection, you lot'll receive cyberspace service via 5G wireless streaming. Verizon is planning a wider rollout in 2022, and of course, hasn't said anything near price still.

There are all the same numerous questions to exist answered nigh how well these services will practically work. Companies accept talked up 60GHz wireless connections and insane bandwidth capabilities over short-range connections for years, and many companies, not simply Verizon, are interested in moving away from fixed wireline installations and towards wireless service. Google Fiber may have begun with a bang with wireline fiber rollouts, but the company has as well telegraphed its own shift away from wires and towards wireless service using millimeter ring waves. Frequency ranges contemplated past various companies for broadband deployments accept ranged from 25GHz – 60GHz, so there's a huge range of spectrum covered by these options, at least in theory.

But how much will these benefits actually accrue to customers? Based on LTE, I'thousand not particularly optimistic. Over the last well-nigh-decade of LTE service, ISPs have establish new ways to charge insane amounts of money for internet by adopting per-gigabyte pricing plans rather than the unlimited plans that typified the 3G generation. Today, information technology's generally incommunicable to buy cellular internet at anything like competitive pricing compared with standard wired service and it's hard to see how that would change going frontwards. Companies that have made such phenomenal amounts of money have niggling reason to change their pricing strategies.

5G's hope is that it tin effectively serve as a unmarried pipage into the dwelling, without a demand to distinguish betwixt wired service and cellular, or even between Wi-Fi and cellular. That'southward certainly what Verizon is pushing, with the idea that its internet service would serve as the only connexion you'd ever need. Only that's also before we consider the issues associated with 5G related to signal strength attenuation, line-of-sight transmission requirements, and the fact that both air and h2o absorb millimeter ring signals depending on their wavelength (oxygen molecules in the atmosphere absorb 60GHz signals rather well and there's a water-related bump between 20 and 25GHz as well).

In theory, cities are ideal places to deploy 5G — huge numbers of customers are packed into residential districts — but the increased attenuation also means you need more line-of-sight transmitters to reach individual customers, which could mean increased capital costs. Equally a result of this, there's a general expectation that 5G rollouts will be far more expensive than their LTE counterparts. It should be noted that estimates on this indicate vary widely, with some analysts pointing to as much as 2x the cost of 4G rollouts while others predict more pocket-sized increases. One approximate from Bloomberg concluding year pegged the additional backhaul requirement every bit costing as much as $200B. Some analysts are concerned that 5G service could exist so expensive to deploy, carriers will practise everything they can to claim to offer 5G service without actually deploying information technology. Someone is going to have to pay these costs and information technology's probably going to be you.

5G should exist much faster than LTE, and it'south got the theoretical capability to extend gigabit service to more homes than can receive it now. The merely question is, will information technology exist deployed at price points that make it affordable and reasonable to use as a general cyberspace service rather than solely for mobile devices? Based on the history of US Isp mobile information pricing, I'grand anything but optimistic.
