The former Tottenham boss could not prevent the R's from being relegated last season but is determined to put together a squad good enough to mix it with the best in the Championship to give themselves every chance of returning to the top flight.
"I know the kind of players we need and I'm working with Philip [Beard] and the owners to get deals over the line," Redknapp told the club's official website.
"We're in constant dialogue. We're all on the same page and want to bring success to the club.
"I am committed to QPR. I want to do well for the club and I want to take it back where it belongs, in the Premier League.
"We're trying to bring the right types of lads into the squad - players who have the right mentality, ability and character to get us out of this division.
"I know the game and know what QPR need to get back into the Premier League. It will be a difficult task but a challenge I am excited about undertaking."
