Im trying to expand the range of my wifi network, and Im not sure exactly what to expect from a +27 dbi antenna. As I understand it, this will cause the power density to increase by a factor of 2^9. Does that mean the range will increase by a factor of 2^9? or would it be more like sqrt(2^9) from an inverse square law? or something else entirely? If anyone knows the math behind this stuff, Id really appreciate any help. Thanks.
