A simple handheld item allowing the player to send signals from certain wi-fi components in a limited range. Upon equipping it the player can select wi-fi channel from which signals can be send. With regular battery cell inside the player can trigger all wi-fi components in range of 40 meters of a certain wi-fi channel losing 20% of battery cell's condition while upgraded battery cell has a range of 50 meters and consumes 12,5% of it's condition.

I'm too lazy to think of what should be the price in credits for this item and if it can be crafted.
