    Default Durban WiFi Mesh

    This thread is for Durbanites keen to build a mesh network.

    We already have 4 guys that are interested, but obviously we need to more ppl to build a decent city-wide mesh [:)]

    Spamtheman in CT is busy putting together a guide to build links at around R500 per location. While waiting for that, I'll be doing some investigations and will post outcomes here.

    Spam, what brand are you buying, how much and from where?
    Also are you only doing point to point (ie. wireless adapter + antenna) at the moment?

    I'm buying X-Micro USB 802.11g adapters they're available from Genex for R175 ex VAT. The point of the excercise is to do this as cheaply as possible though and they also have 802.11b adapters for R140. If the cost of entry into a wireless mesh scheme is low enough you could get enough people involved to turn it into some form of usefull network. At the moment it looks like I may be able to do the one end of a link for about R300 which would be awesome. Who can't afford R300 once off? Here's a hint don't use your telkom line for about 2 weeks and you should have it covered.

    Erm, we'll see :P. On a point to point connection we should manage about 8km barring LoS issues, but I only need to get about 1.1 km for my link.

    hmm, that sounds great,

    how would we go about omni directional, point to point i assume is from one user to other pointed in correct direction,

    i would like something where i can get x people connecting to me,

    Well one could simply purchase an omni-directional antenna and connect it to an access point. My idea is more of a poor man's WiFi link, doing it as cheaply and easily as possible.

    I'm looking into getting hold of dual band A + G APs.

    The reason is that for a mesh to scale, u need to seperate backhaul and local access.
    The ideal way of doing this is to set the AP to allow all local users to connect through 2.4Ghz 802.11b/g, and then to use the more powerful 5Ghz 802.11a radio in long distance point to point backhaul. To dedicate the 802.11a radio, all one need to do is restrict access to the MAC address of the AP on the other side of the backhaul...

    Trying to find prices now...
