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 communi-
cation 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 metal, 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 stations. 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.
