Slideshow5G Will Be 100x Faster Than LTE? More Like 2.7x Faster

5G multiplies bandwidth Multiple bands and sub-bands aggregated for use with high-order MIMO ('massive' MIMO, Co-MIMO, MU-MIMO, MS-MIMO creates a signaling environment in which use is more flexible.  That is a foundational aspect of building virtualized RAN. 

 

5G can be 100x faster than 4G.  However, that begs asking a structured set of questions/parameters including:

 

What spectra bands are available to the operator?

How will demands for the bandwidth, ultra-low latency, local -to-remote storage-server facilities that feed bandwidth, grow over the 1, 3, 5, 10 year time span? 

 

The FCC is making about 120 times more spectra available. The use comes are variable costs of acquisition and deployment due to the range and other signaling properties.  It is not practical for that to be put to use to add capacity far ahead of market demand.  Operators must build networks 2-5 years ahead of demands while back-filling for unexpected broad and local growth patterns. 

Multiple band aggregation has resulted in higher bandwidth throughput and better network utilization, as reported by US and international operators.  Multiple station/node and user-device using multiple bands from multiple signal direction vectors, sometimes arranged as home/street level, tower, and gigabit support grid(s) is still in its infancy.

Re: Shannon Lives Here The Shannon (Shannon-Hartley) Theorem applies to the maximum signaling through a noise-impacted single-channel.  5G is about that but is much more about the use of multiple mode differentiation of signaling.

 

Shannon-Hartley had evolved to within a few tenths of a percent of practical limits.  Chip, device and equipment companies have come to rely on the use of multiple path, multiple spectrum band and sub-bands and tiered and vector differentiation methods.  Beam - formed MIMO including massive-MIMO array signaling far exceeds the gains made in the already near perfection S-H Theorem grains.  We can see this hastily in practice in the specifications of 5G and related RF chipsets. 

 

Have you heard of 'Cooper's Law'?  Or of Moore, Alamouti, Cooper's Law'?  These describe the multiple-disciplinary impacts of using Shannon-Hartley optimized signaling magnified by multiple-station, multiple-channel band signaling.

Spare a thought for 5G users in Australia... There have to be some red faces in Australia, right? Max download speeds on 5G are slower than on 4G??

Someone's shrimp is gonna be thrown on the barbie...

Shannon Lives Here "Results generally indicate that operators' 5G speeds and coverage directly correlate to the types and amount of spectrum they're employing."

In other news: objects fall to the earth if you drop them, water flows from high pressure to low pressure, and energy is conserved.

Nothing magical about 5G. Somewhat better spectral efficiency than 4G, but Shannon's theorem still applies. The FCC gives wide allocations to the mm-wave bands and scrounges in the mid- and low bands.  mm-wave coverage requires lots of antennas. With 5G, you can have very high speeds, you can have very wide coverage or you can have reasonable deployment capex... just not all three at the same time.
