Site survey was done this morning. Plan to use a 3 radio antenna array mounted on a chimney. Currently two rooftops are in play: one as the anchor point and wired backhaul location, and the other for wireless backhaul to extend the coverage. -MichaelWeinberg 11/13/04

Hardware Information and Prices

Backhaul Infrastructure

This is the infrastructure that will "cloud" the Mississippi area with the main source of network conectivity.

The backbone of the network will look something like this: - AaronBaer BR The building at the corner of Mississippi and Shaver will host the main source of the network. This will consist of three wireless devices. One device providing an onmi-directional presence and two devices with dirctional vagi or patch antennas with high gain one pointing south and one pointing north along the length of Mississippi. This point will also manage the point of presence to the Internet which is expected to be a 6mb/6mb dsl line donated by a to be announced ISP. BRBR For the initial roll out there will be two other backhaul points south of the initial node. One point half way down the down the main area in question residing on the other side of the street, rebroadcasting an omni-directional signal to the midpoint of the network. The second point will be at the end of the area in question at the crest of the hill rebroadcasting and omni-directional signal locally and a directional signal which will crest the top of the hill and point towards downtown Portland.

Client Infrastructure

Each point where localized connections will be made the client will connect to the main backhaul of the network using a WET54GS5 bridge. This divice allows for the local rebroadcast of the originating network passing mac addresses correctly. BRBR Each local client can maintain proper signal coverage for the imidiate area with local Access Points.
