im working on a project related to embedded webservers, i would like to know about the capabilities of the RTOS in wireless applications, the energy and memory consuming is probably much longer than in ethernet wirings?
Thank you in advance

Sorry, I don't understand your question, but you might want to take a look at: http://www.sensinode.com/products/
