I need to send a short serial message over a distance of about 100 meters by
radio.
The message is only generated a few times an hour in response to a
real-world event.
Neither speed mor "life or death" accuracy is an issue.
I am hoping someone can suggest an inexpensive "off the shelf" hardware for
this.
This is a USA application, and avoiding licensing hassles would be a big
plus.
Thanks,
