Yeah I shouldn't have said constant I had that thought wrong. I guess it is better worded as continuosly syncratic rather than time based. I guess I was thinking the regular check-in would have caused the magnetic interference every time instead of just when the connection was amplified.
I thought TDMA would have died with 2g though. We have so many devices now I would think it would be impossible to have time slots for check ins. Sounds like something fun to look into but unfortunately I doubt I'll ever have time to play with that.
Always something new
