1st: I would like to thank you for your time. 2nd: I was asked by a charity organization to help building a system and network for the charity center where they help the most needed groups in the society as much as they can. We need to keep the budget as low as possible. We need help choosing cheap network devices (Routers-Switches-APs) but good enough not to impedes the work.
Notes: 1- The Router will be connected to ADSL so the users can access the internet and to allow remote monitor for the surveillance cameras. 2- The PCs numbers in the pictures are the actual real numbers of PCs in each subnet. (maybe very few cellphones connected to some APs and a few printers). 3- Merging vlans is possible if necessary. 4- Can unmanaged switches be used to reduce coast? would it possible to use cheap non-Cisco switches and access points that doesn't understand Vlans?. Switches and APs from TP-Link as an example. 5- I know that the SW_0 is considered a single point failure, but we have to work with a very low budget. 6- I'm an IT technician not a network engineer (studing to be), so I don't have much experience and knowledge with cisco networks. I'm kinda a CCNA level network engineer.
Help us to make to make things better for the most needed people out here.
Thank you again : )
Have a nice day everyone.
