"Radiofrequency issues" in Patriots/Jets camera encounter?

Apart from the issue a cameraman for the New England Patriots was suspected of aiming a camera at the Jets' defensive coaches who were sending signals to their unit on the field, the National Football League [NFL] is ALSO investigating some radio frequency issues that occurred during the game on September 9, 2007.

A New York Post article observed the following:

The league also was reviewing a possible violation into the number of radio frequencies the Patriots were using during the game, the report said. The team did not have a satisfactory explanation when asked about possible irregularities in its communication setup during the game.

A report at the Bowdoin Orient was a bit more specific on the radiofrequency issue:

Smile, New England, you're on candid camera—caught red-handed Sunday for videotaping and stealing the Jets' defensive signals, not to mention perhaps intercepting radio frequencies of their rivals' coordinators corresponding with one another, propelling the Patriots to a 38-14 rout of New York.

The St. Pete Times raised a different radiofrequency issue:

But not unlike the rest of society, the NFL has gone high tech. And that opens a whole new realm of possibilities.

Years ago, offenses complained defenses were stealing signals, so the NFL went to a wireless radio communication system. Every quarterback's helmet is equipped with a receiver, and coaches call plays using a headset on the sideline.

Now, teams complain about their frequencies mysteriously jamming during road games.

Companies with trade secrets to protect should recognize the issues going on in the NFL with "industrial espionage."
