WIRELESS NETWORKING CONCEPTS2Task 1Antennas are devices that are used in wireless communication to propagate RF signals overthe radio spectrum. These devices are classified based on their operational methods whichyield the following categories:a. Directional antennas – as the name suggests, they transfer radio waves in specificdirections i.e. only one direction e.g. Yagi antenna.b. Semi directional – transfer signals in multiple directions having restrictions in others.c. Omnidirectional antennas – transfer radio signals in all directions e.g. cellular antenna[ CITATION Rec111 \l 2057 ].Horn antenna – a directional antenna that is associated with high gains and directivity(propagation in one direction). It used in conjunction with ultra-high frequencies(microwaves) 300MHz – 3 GHz [ CITATION Rad17 \l 2057 ].StrengthsHigh gains and directivity.Simple to designWeaknessesGain is limited to the device structureYagi antenna – one of the most popular antenna (directional) that is commonly used in thepropagation of television signals, a common household item. Its properties facilitate its longdistance applications [ CITATION Rou17 \l 2057 ].StrengthsRelatively high gains and directivity.

WIRELESS NETWORKING CONCEPTS3A simple structure made of metallic rods.WeaknessesGains are always limitedIts size determines the gain.Cellular antenna – used in mobile devices, a cellular antenna is a good example of Omni-directional antennas as it propagates RF signals in all directions. It’s usually small in size, anattribute that facilities its applications [ CITATION Car122 \l 2057 ].StrengthsOptimal gains Convenient sizeWeaknessesLimited gainsFuture of antenna applicationsHigh gains and directivity are needed when propagating RF signals in long distances, whichnecessitates the antennas that exhibit these properties. In this case, directional antennas aredefiantly the choice as they currently exhibit both of these attributes. Moreover, with theadvances in technology, these attributes can be furnished to enhance their operations.Omnidirectional antennas, on the other hand, are only desirable in short distance applicationsand in systems that require small devices [ CITATION Car121 \l 2057 ]..Task 2Multiple access techniques (multiplexing techniques) are protocols used to transfer multiplesignals in single channels. In essence, a single communication medium such as the radio
