Hi, Frank - Last post for the night. 'By the way, what are the concerns, if any, of wireless LAN base stations operating in the proximity of people wearing pacemakers? Just thought I'd ask..' That question was asked of Hatim, last year. This was his response: 'I do not know about the impact of 2.4GHz spread spectrum products on pace makers; we never performed any studies. However, I can state that the frequency band is the same as that of microwave ovens. With respect to pace makers, our bridges have two advantages over microwave ovens: our bridges are direct sequence which spreads the power over a wider band and they are generally placed outdoors away from pacemakers.' Message 10649939 My impression of transceiver transmit power was that it was ~ 1 watt, but I'll have to check, don't quote me. Using DSSS would further distribute that power. Effects would extremely short (transient). I've never heard reports of any problems in this area of usage. Regards, Jim
