Re: Guide lines Optical link maybe?

Re: Guide lines  

There is a link between the changing magnetic and electric fields in this type of solution.  Any problem in the cabling would represent the challenges with getting good bandwidth.  Sort of like problems with home wiring.

That is why there is a limit to the medium voltage power line I think.  It will be too hard to deal with changes in 110 V lines into homes and businesses.  I wonder how ballast changes and other events where there is more wind or solar will impact things.

Re: Guide lines But what about the link to the premises from the power line?
Duh! 12/14/2017 | 11:26:11 AM
Re: Guide lines LOS is a problem with propagation into free space. Obstructons reflect, diffract and/or absorb the signal.

Since the signal is guided, it just follows the guides.

Duh! 12/14/2017 | 11:20:36 AM
Re: Guide lines Correction: it apparently propagates a magnetic wave along the conductor.

Re: Guide lines OK, sort of. But isn't line of sight an issue?
Duh! 12/14/2017 | 11:07:45 AM
Re: Guide lines Completely different beast.

BPL injects a carrier into the electrical conductor. Nice idea, too many practical problems. I could elaborate, but you get the idea.

AirGig, if I understand it correctly, is using the electric field around the conductors as a waveguide for a millimeter wave carrier. So, kind of like mm-wave radio, except that rather than radiating the signal as a beam directed to the receiver,  the signal travels along the electric field, kind of like coax. The kind of idea that could only occur to somebody who dreams about Maxwell's equations.

5G with AT&T and Verizon will be Full Blast Verizon w/ millimter wave from XO and Straightpath along with AT&T with millimeter wave from Fibertower will be plowing ahead with 5G at full steam with Net Neutrality being shelved. The 2 biggest wireless carriers with robust cash flows will deliver 5G!

Re: Guide lines Broadband over powerlines has been tried a number of times. I wonder what would make this latest effort successful.

Guide lines Given what we know about mmWaves and foliage maybe having them use powerlines as guidelines is not a bad idea at all.
