# SVM hyperplane equations for linearly seperable data

I'm going through Wikipedia article on SVM and came across these equations:

It says:

With a normalized or standardized dataset, the parallel hyperplanes to our required hyperplane $$wx+b=0$$, can be described by the equations $$wx+b=1$$ and $$wx+b=-1$$

What is meant by normalized and standardized data here? If the data is not standardized, what equation should be used?
