Hi,
A while ago, a group of individuals have demonstrated
us with devices that can be used to extend your
network throughout every corner of your company
through the use of electric outlet... A quick googling
tells me that such technologies are already existing
long time ago and some Electric companies in other
parts of the world also are now providing Internet
services to their costumers at an added cost.. Do you
know any ongoing opensource initiative regarding this
technologies??
Thanks
The 'in-building' kind is called HomePlug. It's a good alternative
when wireless, and wired, technology is infeasible. When setup
correctly it's link stability is greater then 802.11x, but expect
speeds in the range of 4 - 10Mbps and about half the range of a
typical LOS wireless link. YMMV, oh and the spec does include
encryption, 56-bit DES I believe. For the most flexibility look for
Ethernet bridge devices.
The other one your thinking of is called BPL, Broadband over Power
Line: http://www.arrl.org/bpl/
A better solution to BPL is fiber on the poles and wireless for the
'last mile', they already have the easements to set everything up but
are just to lazy to do it.
