filled, but apparently this makes it more heat tollerant and reliable on =

days) The switches are inter-connected in a spider web fashion. This way =
they =0A=
are fault tollerant and there are several paths to each user. By using =
secure =0A=
managed switches it is possible to insulate users so that unlike cable =
(HSF) =0A=
networks, users only get packets meant for them (on cable networks your =
modem =0A=
recieves packets meant for everyone and picks out the packets for you. =
On a =0A=
cable network the theoretical speed is 10mb, but because of collision =
you only =0A=
really get less than 1mb (in central Melb, Optus cable speeds have been =
tested =0A=
recently as low as 450K!)</P>=0A=
<P align=3Dleft>Their first network, running at 10mb and using standard =
netgear =0A=
switches in weatherproof shells and powered by power-over-ethernet (i.e. =
one =0A=
cable to each switch was ddicated to provide 4 and 12 volt power for the =
next =0A=
switch in the loop) had a reliability of 76% (most of this was due to =
the =0A=
switches overheating in the middle of the day) So they opened them up =
and =0A=
soldered in additional fans and heatsinks. This increased reliability of =
the =0A=
switches to 83%. Which isn't bad considering what they were and how they =
were =0A=
installed!. </P>=0A=
<P align=3Dleft>They also ran some initial connections by putting =
a&nbsp;5 port =0A=
switch in every&nbsp;third house along a street (port 1 connected to the =0A=
previous switch, port two to the house where the switch was installed, =
ports 3 =0A=
and 4 to the houses either side, and the 5th port to the next switch. =
The =0A=
cabling was run to the pole, and strung from pole to pole. When they =
went to =0A=
Power-Over-Ethernet and could put the switches outside in weatherproof =
boxes, =0A=
because the cabling was already there, they had a base to start with.</P>=0A=
<P align=3Dleft><STRONG>Costs:</STRONG></P>=0A=
<P align=3Dleft>For externally mounted switches that are provided to us =
already =0A=
ruggedised it would cost AU$240 per switch.</P>=0A=
<P align=3Dleft>If we purchased Netgear switches, like they did, and =
ruggedised =0A=
them ourselves we could bring this down to $180 plus the cost of the =
plastic =0A=
weatherproof shells. Cat6 cable is fairly cheap.</P>=0A=
<P align=3Dleft>Cost per user initially would be, including rollout =
costs, in the =0A=
avenue of $150-$200 per house. Cost for the internet backbone and comms =
centre =0A=
would be about another $200 per user. Therefore total rollout would be =
at max =0A=
$400 per house.</P>=0A=
<P align=3Dleft><STRONG>Problems:</STRONG></P>=0A=
<P align=3Dleft>1. Heat on the switches. But this, like anything else =
can be dealt =0A=
<P align=3Dleft>2. Local Council. I think that they could be bought =
around to =0A=
understanding the benefits involved to business and residential users, =
but they =0A=
may pose a problem to getting access to place a cable on the poles. The =
cost of =0A=
digging up to lay cable would be around $100 per meter, which is =
prohibitively =0A=
expensive (adds around $1000 per house). They could argue that more =
cables would =0A=
make the poles ugly (although Telstra recently got permission with no =
fee =0A=
imposed to put up additional 30 core phone cables in most suburbs). </P>=0A=
<P align=3Dleft><STRONG>What would we charge?</STRONG></P>=0A=
<P align=3Dleft>Several possibilities abound. I would propose this...</P>=0A=
<P align=3Dleft><STRONG>$12 per month for limited access to the network. =0A=
<P align=3Dleft>This would let them download at 1mb from people in the =
