Reply To: Cruise onboard communicating
In real life, RF systems have to be able to tolerate the fact that nearly every person on the ship will bring multiple transmitters on board. Got a Kindle? A bluetooth device (headset, keyboard)? A computer? A tablet? You’ll be transmitting, know it or not. And the FCC power limits for these devices are the same as for an access point running on the same band. A HAL cruise ship is likely to be so electrically noisy that one more AP wouldn’t even be noticed, especially if it didn’t advertise an SSID. So, I would not worry any more about having an AP running than about turning on my bluetooth headphones for use with my computer.
It would still be preferable to “hairpin,” though, because the signal would reach everywhere with no special effort.
