How does **Enhanced Trait : Affect Others Only** function as a device?

This is a continuation of this question for Mutants and Masterminds 3e. So, the character I proposed could spawn a minimum of 6 constructs with 30pp worth of powers/skills by using Invention at Quickness 20, but this is from a PL20 character, so making a flood of these critters wouldn’t be that effective unless we were being attacked by a huge, person-man army. That being said, it doesn’t prevent me from making other inventions using the same method. My initial solution is to create beacons to buff my constructs, a power worth at least 2pp per rank (Permanent Enhanced Trait, Affects Others Only, Perception, Limited(my constructs)). Now, I could use this to buff a core stat or a ranged attack by 10 ranks (thus bringing that up to PL12 by proxy), but that involves planting several beacons in series to cover all my bases and still leaves them much weaker than most things that’d be thrown our way. My other option is to drop the Perception range modifier, which would give me the leeway to either buff a core stat/ranged attack to the PL cap and have 12 points to spare or buff 2 things to a more agreeable 15 ranks.

The latter would be the preferred solution, but I’m unclear on how the device itself would function. To that end, I have 3 questions.

  • Would this device have to be a worn piece of gear or a stationary object that my constructs need to interface with?
  • If these need to be worn/carried, is there a limit to how many my constructs can carry?
  • If these need to be interfaced with, what sort of action do the constructs need to take?
