Advantage and disadvantage of network

Wireless Networking Technology
It is the future of computer and Internet connectivity. The data is transmitted in air through microwave and other radio signals. Since no wires are used, so data can be sent overseas easily, efficiently and more reliably. Cellular phones are part of huge wireless network system. Police department and other security agencies use wireless network to communicate important messages. In areas where the telecom infrastructure is not proper, Internet access can be provided using wireless technology. But some disadvantages are also attached to this networking such as:
(i) Wireless networks are little slower than network connected by ethernet cables.
(ii) The signals are more susceptible to errors since anyone can break into the signal.
(iii) A major issue is compatibility of different components being networked which might require an extra effort.
(iv) Some people are of the view that excess of microwave radiation might cause some health hazards in near future.
