Thanks michael , i will amend profile but we are talking about UK
I basically need to be able to create a wirless ad-hoc communication between either a single pc or eventually a single phone (would be andriod to start with as i have deloper tools for an app) never both at any time.
It will be in the open with very few restrictions as the head unit would always be in line of sight.
There would be no internet conection
To be honest i have not considered speed yet but it would be a continous string of very and i mean very small data that the program or app can decipher. At this stage i only need to pass 3 pieces of infomation being recorded by the arduino
there are no plans as of yet for mesh routers but maybee a good idea.
