Outdated technologies such as; pre-existing copper, or any twisted pair or coax is still restricted by capacity limitations. If you could compare this then it would be a measure of the time it takes for you to think of an idea or conceptualize as your body reacts and we want your building to act in that same way that you think while having the systems to operate without any delay that has become normal everyday by product of our everyday use of wireless real world results. You have been promised high speeds that never seem realized as false promises and the only true outcome is sharing bandwidth that you have no idea of how many accounts that you’re sharing with.
FIBER OPTIC VS. 5G WIRELESS NETWORKS: A CLOSER LOOK AT AN EMERGING DEBATE (READER FORUM)

Excerpts from this post:
Fiber optic networks and their role in 5G
Fiber optic networks are a type of high-speed wireline network offering improved speed, security and bandwidth over legacy copper systems. Fiber optic technology has long been used in long-haul networks due to its high performance over long distances fiber can travel as far as 40 miles without losing signal strength.
Now fiber is increasingly being used in metro and access networks instead of copper. And because copper can only carry a gigabit signal about 300 feet, many businesses choose to continue the fiber connection all the way to their premises called a fiber to the premises (FTTP) configuration to avoid losing signal strength. In essence, fiber optic networks are limited only by the technology used to transmit and receive signals.
In an ideal world, every phone, smart sensor and mobile device could be directly connected to the fiber backbone but that would limit the mobility of the devices. That’s where 5G wireless network technology comes in. 5G networks will essentially be designed to bridge the short distance between a mobile device (as in 5G mobile services) or business (as in 5G fixed broadband) and the fiber backbone.
The evolution of wireless networks
Recently, we’ve been reaching the limits of current wireless network technology. Average mobile data usage has inched up steadily every month since 2014, mobile traffic is set to quadruple before 2021, and a user’s bandwidth is expected to grow nearly 50% every year according to Nielsen’s Law of Internet Bandwidth. A new solution is needed to keep up with these bandwidth and speed needs, and 5G may be the answer.
How 5G works: Moving from macro cells to small cells
4G macro cell towers relied on radio frequency spectrums, which were able to travel great distances reducing the number of towers needed to serve an area but were unable to achieve the growing speed, latency and bandwidth businesses will require in coming years. And adding more towers would be an expensive fix.
5G wireless networks will use higher frequency millimeter waves. The millimeter wave spectrum provides exponentially higher bandwidth with virtually no latency.
Unfortunately, millimeter waves can only travel about 250 feet. Because of this, 5G will force telecom companies to switch from the large cell towers to low cost, low power small cell sites basically radios that will transmit and receive signals from devices within their small coverage area. Small cells are much cheaper than macro cell towers and require less power, allowing for a denser scattering of cells on streetlamps and buildings.
This 5G small cell model will bring the fiber backbone closer to the end user, allowing for use of higher frequency waves and vastly improving the quality of experience when using wireless devices. Indeed, the future success of 5G hinges on the availability of a deep fiber backhaul.
The essential relationship between fiber optics and 5G wireless networks
5G wireless small cells and their fiber wireline networks will never be mutually exclusive. To understand the relationship between wireless and wireline networks, it’s helpful to think of a city’s network in physiological terms: 5G will function splendidly as the capillaries (mobile fronthaul) of a city’s networking system but internet traffic will travel nearly its entire journey in the veins or arteries (fiber backhaul).
In fact, much like the human bloodstream, only about 11% of traffic is carried by wireless networks, according to a study by Deloitte
. The other 90% of internet traffic is supported and carried by the wireline network.
