Wireless hotspot creation with eight homes

 * Share one VDSL2+ modem between eight homes (a,b,c,d,e,f,g and h)
 * Node1 house(a) has two http://scratchpad.wikia.com/wiki/LinksysWrt54g. The remaining seven connects via LinksysWrt54g via patch antennas.
 * House(a) North-side and South-side gets a LinksysWrt54g each.
 * The North-side and South-sidewrt54g AP connects via a switch and router to the VDSL2+ modem which hands out a DHCP lease.
 * Pirate LinksysWrt54g are imported at bulk for $10 each from http://www.starnetwifi.com order a 100 units.
 * We produce our own patch antennas using CNC machines at R60 each.
 * Pigtails, BNC connectors are imported for virtually nothing from China.
 * Setting up an eight home Wi-fi hotspot around house(a), Node1 will cost R200 each or R1600.
 * a,b,c,d bridges the street via wireless to e,f,g and h where node1 is located.

Fixed wires and DSLAM

 * The magenta circles indicates the nodes seperated by 100m each.
 * Each node has a VDSL2+ modem connected via TwistedPair to the CO or red cylinder in the middle of the street.
 * The 500m stretch of nodes1-5 on the left connects to the CO and the nodes6-10 connects via TwistedPair
 * 1km of ten twistedpair is R5/m or R5000
 * The length of the street is 1km with each yard 50m in lenght for a total of 80 homes in the green and blue blocks.
 * The next CO is in the pink block of homes.
 * This setup means only every second block Block-A(green) and the pink block needs to create ten nodes of TwistedPair.
 * The cheapest way of creating nodes is http://scratchpad.wikia.com/wiki/PolyPipeOnPerimeters.
 * PolyPipeOnPerimeters need not be permanent and can be gradually replaced with underground ducting or telephonepoles.
 * The CO scales to any size and connects via microduct and fiber.
 * Every 100m or evey node a ZoneMinder box can be placed which interfaces via cat-5 to the switch at the node.

Total costs
* 1km twistedpair = R5000 * Wireless link per home R200x80 = R16000 * VDSL2+ http://scratchpad.wikia.com/wiki/DsLam $1200 = R9000 * Ten VDSL2+ modems at R1200 x 10 = R12000 * Or R525/home

[b]For about R600 each of 80 homes gets a 12meg, stable, localloop link.[/b]
