Define "strong"? If office building is close to each other, there is no easy way to prevent your signal to "leak" outside your building's surrounding. It's the nature of radio waves in general. I agree with Eric. In order to minimize the effect of radio leaks, you have to combine AP placements and indoor directional antennaes among other things. I can also think of disable SSID broadcast as another.
The problem is how do you provide coverage to a majority of the building floor space without exceeding the boundary.
Thanks for the advice.In fact,i did disable the SSID broadcast on WLC,but it doesn't mean it cannot be scan over the air channel.Currently all the access points are installed and not possible to removed. So actually i'm looking for alternate solution that possible to confined the signal/coverage within the building OR around the building area but not too far away from that.
Using the WLC, you can manually override the RRM to raise or lower the signal strength and footprint of your radios per AP basis. This will take alot of footwork. Your best bet if for someone with a wireless scanner to walk around taking readings and communicating back to the Admin to raise or lower the signal strengths.
This is one of the consequences if a Wireless LAN Site Survey is done incorrectly or incomplete.
