Disadvantages of a wireless topology :-
Disadvantages of wireless networks include a greater chance of signal interference, blockage, and interception. Other devices and machinery that emit radio frequencies or "noise" can cause interference and static, which can disrupt the bubble of communication around the cell. Another source of noise is lightning during storms. This noise is the same static you hear when lightning strikes while you are speaking on a phone. Blockage can occur in structures that are made of thick stone or metropolitan, which do not allow radio frequencies to pass through easily. This drawback usually can be overcome somewhat by changing the frequency used by the devices to a higher frequency you can determine early if this is going to be a problem in your building by trying to use a radio inside the building to pick up some radio station. If the radio will not pick them up, the building material is too to pick up some radio station. If the radio will not pick them up, the building material is too thick to allow radio frequencies to pass through the walls. This problem can be overcome by installing a cell in each room where a PC or network device will be placed.
Another major disadvantage with wireless is signal range. One of the key steps to securing wireless communication is to limit who can connect to the network and to encrypt the traffic in transit
