I was reading an article about how wireless network are subject to
interference, when I came across this text:

------
That's what happened when doctors with Carilion Health Systems, a
Roanoke, Va.-based health company with 100 doctor offices and eight
hospitals, began using a new wireless endoscopy capsule last year.
When swallowed by a patient, the capsule -- a small device about the
size of a vitamin tablet -- wirelessly transmits images to a receiver
as it passes through a patient's system.

Carilion's doctors were given a demo capsule early last year, but they
hadn't met with the hospital's network administrators to inspect the
device before they began testing it. Days later, the capsule's high-
powered transmitter ended up disrupting the wireless network for the
entire clinic and bumped wireless PCs and handheld scanners used by
doctors and nurses off the network. Some of the devices that got
knocked off the network held vital records about patients' medication
dosages.

To my knowledge, only this company has this wireless imaging endoscopy
pill. Not a show stopper, but some interesting hurtles that need to be
overcome.
