For example say computer A is as far as it can be while still in range of Computer B but out of the range of computer C. However, computers B and C are still in contact. Computer A will still be able to contact computer C routing through computer B.<br /><br />The server has a 160GB HDD but the XOs have flash based storage. Each has around 450MB free.<br /><br />The mesh network should not be used when a server/access point is in range. The mesh is slower and does not have as high of bandwidth. Ask Ruben to double check but I think you would want 3 access points plus the server to support 100 laptops.<br /><br />I don't know how well two servers will work together because they might conflict. I would talk to Ruben about this as well.<br /><br />Access points can be purchased here in the US but you need to make sure the power adapters support the deployment countries power voltage OR you need to get a power inverter. Search "Wireless Access Point Compatibility" on the laptop.org wiki and you will see which work.<br /><br />Generators generate electricity but different generators generate different amounts of power (110V or 220V). The efficiency determines how much petrol it takes (think MPG in a car). Your team should have specified to Nia which power adapters you want. Power strips just turn one outlet into several. You will need to be sure on the plugs you requested for deployment and the plug which will come from the generator.<br /><br />NGOs can have internet without the vsat depending on if they have hard wired lines. We aren't buying vsat modems because we chose schools which already could have internet.<br /><br />What do you mean by solar batteries? Batteries to store energy obtained from solar panels? It's up to us to buy everything except the Laptops, the server and the power cables.<br /><br />The network cards come with the server. One is built into the server and the other is on a USB connection with an adapter provided.Michael Steinhttps://www.blogger.com/profile/13563928598184049542noreply@blogger.com
