OPLIN 4cast #451: Bracing for 5G
August 19th, 2015

[image: 5G wireless networks]We are about to hear a lot of hype and hoopla
about 5G wireless. If the rollout of 4G is any indication, wireless
carriers will start making claims about their 5G networks before 5G is even
officially available. There will be talk about increased capability for the
Internet of Things, including self-driving cars and the ability to watch
super high definition video on your tablet, maybe while your car drives
itself. But before any of these promises can come to pass, a lot of
groundwork must be done, including assigning and selling wireless spectrum
for 5G. Some of the lower-frequency spectrum could come very close to the
unassigned TV spectrum currently used for the TV Whitespace
<http://www.oplin.org/4cast/?p=5217> connections that some libraries are
using.

   - IMT-2020 is the future of mobile - but you can keep calling it 5G
   <http://www.pcworld.com/article/2939172/imt2020-is-the-future-of-mobile-but-you-can-keep-calling-it-5g.html>
   (PC World | Stephen Lawson) "The International Telecommunication Union
   (ITU) has decided to call the next-generation cellular system IMT-2020.
   That name may have a hard time catching up with '5G,' a tag that's been
   applied to just about every future mobile technology in the works: Googling
   '5G mobile' brings up 12.9 million results. But it's a clear sign of
   progress toward the concrete. Where there's a bureaucratic-sounding numeric
   acronym, can a formal standard be far behind? The ITU now has an answer to
   that question, too. It's set a timeline
   <http://www.itu.int/en/ITU-R/study-groups/rsg5/rwp5d/imt-2020/Pages/default.aspx>
   that calls for the standard to be finished in 2020. Hence the name, which
   follows in the footsteps of IMT-2000 (3G) and IMT-Advanced (4G)."
   - The promise of 5G <http://techcrunch.com/2015/08/15/the-promise-of-5g/>
   (TechCrunch | Hossein Moiin) "There are several technical hurdles to
   overcome, and the biggest is for the industry and the world's governments
   to work together to develop a standard for 5G. Setting a standard will
   allow multiple devices, multiple networks and multiple users
   (humans/machines/drones/robots/phones/wearables) to access the network and
   its data in a consistent way, eliminating the need for humans to intervene.
   Additionally, allocation of more radio spectrum is vital to meet increased
   demand for capacity and data rates beyond 2020."
   - Leading towards next generation "5G" mobile services
   <https://www.fcc.gov/blog/leading-towards-next-generation-5g-mobile-services>
   (Official FCC Blog | Tom Wheeler) "The NPRM [Notice of Proposed Rulemaking]
   will focus on developing a flexible regulatory framework that will allow
   maximum use of higher-frequency bands by a wide variety of providers,
   whether the service they provide is mobile, fixed, or satellite. I
   anticipate that we will explore a range of regulatory strategies depending
   on the specifics of each proposed higher-frequency band, including
   licensed, unlicensed, and hybrid shared models. In addition, as an
   implementation of existing flexible rules, I foresee lower-frequency bands
   playing a role in 5G. For example, the timing of the incentive auction
   makes the 600 MHz band a prime candidate for deployment of a wide-area 5G
   coverage layer. In much the same way that 700 MHz paved the way for
   America's world-leading deployment of 4G, so could 600 MHz accelerate U.S.
   deployment of 5G."
   - The race to 5G: Inside the fight for the future of mobile as we know it
   <http://www.techrepublic.com/article/does-the-world-really-need-5g/>
   (TechRepublic | Jo Best) "'An additional challenge will be to find a
   globally harmonised band for 5G roaming since all suitable spectrum is
   already in use in one or another part of the world,' said Thibaut Kleiner,
   head of the European Commission's CONNECT (Communications Networks,
   Content, and Technology) Directorate-General. One solution to the spectrum
   crunch could be to look beyond the lower-frequency spectrum - between
   700MHz and 2.6GHz - used by most carriers today, and move towards higher
   spectrum bands such as 6GHz, 28GHz, and 38GHz. At the top end, beyond
   30GHz, these extremely high frequency bands are known as millimetre wave.
   Bringing those bands into use is both one of the most exciting, and least
   guaranteed, areas of 5G development."
