What is the range for co-op in Bloodborne?

I'm a bit hesitant to level up too much because I like playing co-op, so I'd like to know how the range to summon and to be summoned is calculated.
Does it work by level, like in Demon's Souls and Dark Souls? What are the ranges and can you have any influence on them?

TLDR:
your level * 0.1 = x
maximum level of coop: your level + x + 10
minimum level of coop: your level + x -10
Basic algebra needed, (very basic) but I hope this helps.
EDIT: It's the same as DkS and DeS summoning, so google a Dark Souls 1/ Demon Souls summoning calculator, it's far easier and requires you to use less brainpower.
EDIT #2: Make sure you and your friend(s) are using the same network password, which can be found in settings, network.

Answer 2
Keep in mind that people don't know for certain. It's being assumed right now that it works as David posted, because that's how it worked in Demons Souls. Could be that the higher the level, the higher the range... Just a theory and there's nothing to prove or disprove it.
