Work in Progress
The cellular industry is saying 2020 was going to be the year of 5G. It will change the way we live, work, learn, play, and improve our global society. Whoopee!
Oh wait, some in the industry are now saying maybe sometime in the 2020s.
Hype is the space between fact and fiction. The Hype storm that 5G is generating, is awesome.
Most of 5G marketing is Fiction, until the technology reaches the Slope of Enlightenment on the Hype Cycle
The 5G fiction is quickly climbing up the slope to the peak of Inflated Expectations. Then it will slide down to the Trough of Disillusionment until it it begins to climb the Slope of Enlightenment and becomes reality.
Cellular Networks Generations¶
5G is the fifth generation technology standard for broadband cellular networks. It is very different than 4G and older wireless standards. It is extremely fast, require new phone hardware and software, new towers with new hardware, and big changes to phone and network designs.
It is the very fast speed your smartphone may some day use to connect to the Internet.
1G 1982 - 2.4 kbps - Retired
First generation of broadband cellular network technology - Retired
1G is an analog technology and the phones generally had poor battery life and voice quality was large without much security, and would sometimes experience dropped calls
2G 1992 - 64 kbps - Retired
The advance in technology from 1G to 2G introduced many of the fundamental services that we still use today, such as SMS, internal roaming , conference calls, call hold, etc..
3G 1998 - 2 Mbps - Soon to be Retired
This generation set the standards for most of the wireless technology, web browsing, email, video downloading, picture sharing and other Smartphone technology
4G 2011 - 100 Mbps
4G is a very different technology as compared to 3G and was made possible practically only because of the advancements in the technology in the last 10 years. Its purpose is to provide high speed , high quality and high capacity to users while improving security and lower the cost of voice and data services, multimedia and internet.
5G 10 Gbps?
Apple New iPhone 12 Optimized for 5G
It supports more 5G bands than any other smartphone, with all models connecting to both millimeter-wave and sub-6GHz spectrum, and a data mode that switches iPhone from 5G to LTE when 5G speeds aren’t available or reliable.
The blazing speeds promised will not materialize for most people using the iPhone 12 or any 5G enabled device on today’s network. It is like trying to drive a Ferrari 200 miles per hour on roads not built for that speeds.
There is not much one can do using a 5G iPhone that can not be done on a 4G iPhone, until the 5G network is up and running, and supporting 5G millimeter:.
Apple’s 5G Move Payoff
As 5G hype leaves the Hype Cycle Trough of Disillusionment and begins ascending the Slope of Enlightenment where consumers begin to understand the technology better and how it may benefit them, I think Apple’s 5G move will pay off big time. By then, Apple will have multiple technology iterations able to effectively utilize 5G millimeter:.
Verizon Announces “Nationwide” 5G Coverage
“Nationwide” doesn’t mean it’s available everywhere. It will not make much difference for most consumers buying 5G enabled phones
AT&T’s 5G is Slow
AT&T’s 4G is faster in nearly every city tested by PCMag
5G Stark Realities¶
5G Technology Goals¶
The core of new networking technologies are built using industry standards. The 5G standards are in a state of flux. Some early 5G deployments are doing makeovers because standard changes
There is a lot of excitement over 5G’s promise of blazing speeds, lower latencies, and more robust security than 3G and 4G networks. However, network operator have their own timetable for rolling out the next-generation cellular technology. 5G will be a patchwork of 3G, 4G, and 5G networks. For the next few years, 5G won’t be able to fully deliver on its promises.
Realizing these three 5G technology goals is more complex than previous generations. Some of the necessary technology may not exist or be experimental, fewer engineers and technicians have the necessary skills, and high cost of deployment. Consumers may balk at higher product and service costs, and limited coverage
Blazing speeds require using higher-frequency radio waves than 4G cellular networks
5G is an umbrella term. There are two 5G radio-frequency spectrum bands, 5G sub-6GHz and 5G mmWave. Additional bands at higher frequencies may be added.
The capability of of 5G signals penetrating atmospheric, automobiles, buildings, glass, pockets, purses, vegetation, walls, and other obstacles, decreases at higher bands and frequencies
Is a a similar frequency range to current 4G cellphones giving download speeds a little higher than 4G. Cell towers have a range and coverage area similar to current 4G towers.
5G also uses microwaves frequencies with each cell tower providing service up to several miles in radius.
The 5G millimeter wave band is the 5G holy grail. It may achieve download speeds of a gigabit per second comparable to cable internet.
