The following has been reproduced from one of the submissions to the ACA
enquiry on the management of BPL interference.
The full document can be found at:

On there you will find the link to the pdf document.
Anology:
The following analogy is proposed in a light hearted way to illustrate a
tangible example of BPL systems and not to be disrespectful to anyone in anyway.
Lets imagine broadband data to be sewage and interference to be the smell.
There are odd discharges and occasional smells around cities but are manageable.
There are many types of sewer pipes out of sight, some quite large with
no smell.
BPL innovators have discovered they can carry sewage in the open gutter but
ignoring the issue of smell.
BPL proposals are asking the regulator to allow it to spill into peoples front
yards causing a huge smell.
BPL proposals are asking professionals to accept the risk of the
bad smell and contamination as well as affect life and safety systems.
There are no standards to define the way sewage flows in gutters, or
indeed the volume of sewage.
There is conjecture as to how the smell is measured or standardised.
The regulator is seeking a way to manage the smell.
The conclusion is to contain the sewage to well defined paths taking every
effort to eliminate or minimise the smell.
Applying this to BPL, means that it may be fine in certain areas,
but the only way to manage the interference is to turn it off at the source.
