Block wireless outside a specific room

[mfordtoday]

I am looking for some suggestions on how to block wireless outside a specific room.

I am having bleed out into the halls and i don't want that.

Is there any way of creating a virtual curtain ?

any creative ideas are welcome. I don't see turning down the signal strength as an option.

hello, 

there is no way to reduce propagation of the  signals untill you reduce the power.....  other solution will be to use metal walls, or metal grid  it reflects the signal.

Since you ruled out the only generally reasonable way to accomplish the task, might I suggest you give more specifics of what the situation is if you want creativity to flow. Keep in mind that modern wireless systems are designed to find a way through and around obstacles. Not much thought is given to restricting propagation, because output power and encryption are the standard ways to restrict access. 

Good luck
