BroadBand over Power Line. Is it better now?
« on: December 12, 2017, 08:32:30 PM »
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:

BPL 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.

Here is a short article that mentions the Uk has a different outlook on BPL.

Hee is more about BPL over high voltage. But it is not about the ATT&T microwave mode thing that At&T is doing.

In 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."

Have yu used any form of BP?L
Did you like it? Do yu still use it?  :)

** Use of one wire for microwave.

as discussed in the TP LINK thread here; https://www.computerhope.com/forum/index.php/topic,163860.msg970116.html#msg970116
the whole idea of ethernet over any sort of power line has run its course, in my opinion.

it may be convenient for utilities companies, as they own the 'wires and poles' but start delivering that to the general public through service providers and it gets real messy real quick.

plus other technologies have superceded that requirement.
for LAN use, get a top range router.
for WAN use, use optic fibre or, again, wireless.

years down the track, surely cable delivery of data packets will be replaced with some sort of improved wireless technology.

mind you, I'm still waiting for my god *censored* hoverboard. ;D

I'm not aware of any BPL availability here in my area (central Ohio).   I used DSL from the local telephone provider for many years and then, about 7 or 8 months ago, switched to Spectrum (formerly Time Warner) for internet.

Hee is a reference taht may be of some help to technicians who are tyring to get BPL to work insid a bilding that has one electrical panel.
https://en.wikipedia.org/wiki/Ferrite_bead

A clamp on bead to isolate high fequencies on a power cord.


At first the application might not be apparent. What yhou do is place EMI suppressores on the cords going to each and every applicanc, light fixture or computer on the bfanch of the elecdtrical circuts you wish to use for local BPL.
The choke prevents the appliance or deive from asorbing the BPL endergy.

It is kind of like how yu use filters on aphones that share a line with a DSL modem. Same concept. The filter kepps the BPL and other device isolated at the high frequencies.  The bead are cheap and worth trying.

Here is another tefence:

This is an introduction to how ferrite beass work.

... and another.
https://www.google.com/patents/US6933835
This  has a list of patents for improvements in BPL

With some effeortm yu can get BPL to work in a  a area taht otherwise was not so good. Just takes effort and patience.    8)
