Placing transmitters efficiently. Placing 2 Wireless Transmitters just next to each other will not do that much. The wireless signal starts from the Wireless Transmitter''s position, so, if you place 2 transmitters next to each other you''ll only have a net gain of 1 block. Instead, you have to spread your wireless transmitters around.
