Explain why the omnidirectional and centered approach does not work for every network.

What will be an ideal response?

The omnidirectional and centered approach does not work for every network, for three reasons. First, if the signal exceeds the size of the network space, that signal bleeds out. The signal can bleed out a lot in some cases, particularly if your specific space doesn't allow you to put the WAP in the center, but rather off-center. This presents a security risk as well, because someone outside your network space could lurk, pick up the signal, and do unpleasant things to your network. Second, if your network space exceeds the signal of your WAP, you'll need to get some sort of signal booster. Third, any obstacles will produce glaring dead spots in network coverage. Too many dead spots make a less-than-ideal solution.
