This is intended to be a discusion. To start with, the idea is not new at laa. Wikipedia says it was based on technology that goes back to 1914.
Looke here:
https://en.wikipedia.org/wiki/Broadband_over_power_linesBPL is based on PLC technology developed as far back as 1914 by US telecommunications company AT&T.[1] Electricity companies have been bundling radio frequency on the same line as electrical current to monitor the performance of their own power grids for years. More recently there have been attempts to implement access BPL, or the provision of internet services to customers via the grid. The prospect of BPL was predicted in 2004 to possibly motivate DSL and cable operators to more quickly serve rural communities.[2]
The high level of attenuation (or data signal loss) from access BPL power cables had two critical effects: It limited bandwidth, and it attracted opposition from groups within the radio community.
The moddern application has has two major areas. One is for comunicationh inside one building when use of Ethernet cable is not desierable. The other is for broadband coverage of a neighborhood using only the pow lies as the physical connection for data.
Gigabit speed would be needed.Recently AT&T introduced a major advance in deployment of BPL ove high voltage power lines.
This is not the same as the data connections use by the power companies. This is really a microwave system using the high voltage wires as a single wire microwave mode. This is not the same as BPL, put some writes equate the two. What AT&T is using is a mode of microwave transmision over a surface or single wire. ** see footnote.
For home users, there is a variity of equipment for use as an Ethernet bridge. Amazon and others sell BPL for home and small office use.
Here are some referencesyou may link.
Or maybe not.The best powerline adapters for 2017Here is a short article that mentions the Uk has a different outlook on BPL.
https://www.ispreview.co.uk/broadband_powerline.phpHee is more about BPL over high voltage. But it is not about the ATT&T microwave mode thing that At&T is doing.
https://www.lifewire.com/broadband-over-power-lines-817450In my opiobniob, if it even matters, is thatthe AT&T thing is too good to be true. It is a microwve mode taht already has be tested and works good, but AT&T has so many diverse thigns going on it may fail becuase of organizational problems. They already have too much on their place. Still, it you want to know more, here is a link publish back in 2016.
Today, AT&T Labs announced a new wireless technology called Airgig, designed to transmit data at gigabit speeds over existing power infrastructure. The system would move the data between routers at the top of utility poles, transmitting data wirelessly over the millimeter waveband, also known as "gigabit wifi."
