Thanks michael , i will amend profile but we are talking about UKI 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.
You might be able to get by with a wifi setup, maybe with a wireless router using fixed network IP addresses, no routing, etc. If range is an issue, you could use wifi repeaters strategically placed (similar idea to the mesh routers).

There would be no internet conection
This was more in case the arduino and pc were really far away or if you were using cell phone networking on the Arduino.

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 arduinothere are no plans as of yet for mesh routers but maybee a good idea.
Without going to the regulated bands or power levels, you might need something like mesh routers to cover the distance. I have no idea what the limits are (and obviously it depends on the physical layout and amount of background noise). I know with my home wifi routers I don't get that anywhere near 60m.
