There are both advantages and disadvantages to using microwave applications and this is what makes it necessary to understand the applicative arena using a simulator like the OPNET modelling. Some of the advantages offered by microwave systems inclue the wide bandwidth and the non bendable line of sight. In addition it is seen that microwaves also offer good direction sensitivity which is not common with the normal em waves. This attribute makes it easier to design for high gain antennas. The smaller size of the antenna itself makes it easier to use in a variety of application where antenna size considerations may arise.
In addition the biggest advantage of making use of microwaves in communication is their power usage statistics. They consume much lower power than others as the power needed to transmit a high frequency signal like th Micorwave is usually much lesser than that of the power that will be needed to transmit a low frequency signal.Power consumption becomes an important parameter when the equipment made or the time of usage is going to be big or high. In either case the use of the normal em waves would cause greater power consumption. To avoid this more and more equipments are begning to rely on microwaves.
