NETWORKING2Question oneCellular antennaeHaving the right cellular signal helps to understand the basic of having signal or no signal.These antennae find wide application in building, cars, office and other places that are ofsignificance. Their use in cars and office building has find widest application especially dueto the security issuesAdvantagesThey have improved signals strengths.The cellular antennae are cheap to installMost devices for cellular antennae are easily portable since most are installed in the cellphones. These antennae have boosters in case they are to be used in a large range location such asbuilding.They are found to be most convenient for many users since they can be easily placed inundisclosed locations. DisadvantagesThey occur in a wide variety thus finding the right one proves to be more of agues work. Horn antennaeThe horn antennae are majorly used for 300 MHz to 3 GHz and frequencies that can reach upto 140 GHz. They come in various versions including H plane and E plane horn antennae.

NETWORKING3Horn antennae has several advantages. They enjoy the advantage of having limited loss. Thismeans that directivity of this kind of antennae is almost equivalent to the gain. The antennaeare also simple to manufacture in comparison to other antennae. In addition these antennaeare intuitive. On the other hand, horn antennae of acoustic type can be useful transmission ofsound waves such as the megaphone. Moreover, the antennae can be useful in transmittinginformation to the dish antennae where it acts as a means of measuring standard gainYagi antennaeAdvantagesThese antennae are directional with a beam width of between 500 and 700. This thereforemeans that they are useful for receiving lower strength signals only. The Yagi antennae have good range since their physical size receive high gains.The Yagi antennas have mechanism of filtering noise that comes from other sides.Yagi antenna have the advantage of being easy to mount on various structures.The Yagi antenna are sold at relatively lower cost due to their simplicity in comparison toother antennas. Question twoMultiplexing is considered to be the act of combining information streams that come frommultiple sources in order to transmit them over a shared medium. In this systems everysender gets to communicate with a single receiver only. Multiplexing can be done either inform of FDMA and CDMA. FDMA – Frequency Division Multiplexing Access
