Question: Discuss About The Wireless Networking Communication Management? Answer: Introducation IT is commonly known as Yagi Antenna and it is an antenna of directional type. Yagi antenna has multiple parallel elements in a particular line (Yin et al., 2013). It has mainly three part, a reflector element, some directors. The reflector element has a longer size than the driven dipole and the directors have a smaller size. For this kind of design it has higher gain and better directivity. Strengths It has a higher directivity. It has lower power consumption. It has a low maintenance cost. This type of antenna has a larger frequency range. It can achieve very high magnitude of gain. Weakness It has a limited bandwidth and frequency level. Noise and environmental changes can affect the Yagi antenna. Applications The Yagi antenna is mainly used to achieve high value of gain and directivity. It is used in case of frequency modulation for narrow band region. Horn Antennas Horn antennas are also well known as the microwave antennas (Yang Marzetta, 2013). It has given this type of name as it is consisted of a flaring metal waveguide that has a shape like horn. It functions over a frequency range of 300 MHz. The main advantage of the Applications It is used mainly in case of speed enforcement cameras and also it is used in small distance radars (Yin et al., 2013). Cellular antenna Cellular antennas are those which are mainly used in the mobile phones and the cell phones (Inui et al., 2015). Cellular antennas are useful in case of long distance communication. Strengths The cellular antennas are used for the communication along very long distances and it is approximately 45 miles. The capacity of data transfer is very high. It can achieve the connection among any places among the globe. Weakness The main issue regarding the cellular antenna is the connection problem. The size of this type antenna is very big. The number of antennas in every base station has increased value. Applications Cellular antennas are used in mobile phones. It is also used for long distance communication. These antennas are used in the cellular base stations. Selection of antenna type for medium and long distance In case of long distance communication cellular antennas are used in a wide range. In case of global communication this type of antennas are used (Sarkar, Srivastava Saurav, 2014). This type of antenna has a very suitable value of bandwidth and gain. Comparison and contrast of FDMA and CDMA CDMA refers to code division multiple accesses and it is a method that has the access of different channels and it is a blend of several radio communications (Lo Lee, 2013). It is created by spreading the codes using orthogonal codes. It is a suitable example of multiple accesses. FDMA refers to Frequency Division Multiple Access and it is a method that utilises the channel for accessing and it also acts as a channelization protocol (Yang Marzetta, 2013). It provides the users several bands of frequency and is mainly used in satellite communication. CDMA FDMA It has no absolute limit of channel capacity. Cell capacity is limited. It distributes orthogonal codes in the main channel. In case of FDMA the frequency band is consisted of several disjoint sub bands. All terminals can act simultaneously. Individual frequency level is present in every terminal of FDMA. It is flexible and needs less frequency planning and soft handover. It is simple, established and robust. The transmission is simultaneous in nature and each user uses different band of frequencies. When the channel is inactive, it is also inactive. Most recent advanced wireless technologies RFID or Radio Frequency Identification detector is used to keep track of several objects (Han et al., 2015). The RFID acts on the principle of radio frequency which has a range of 134 KHz and for high frequency RFID systems; the value is almost 13.56 MHz Strength RFID is very useful in case of using in inventory management system. RFID is very helpful in case of tracking vehicles. RFID is used in automated tracking system and more advantageous in case of logistical tracking. Weakness The range of RFID is limited and it is not more than 100m. As RFID is a very new technology, people should be aware about it and should have proper knowledge about RFID. Best type of Antenna for future applications Antennas take an important role in wireless communication. Antennas are of different kinds and different types which are already discussed above (Ding et al., 2015). According to the types of antennas the applications are also different in nature. In future the main field of communication will be based on long distances and faster response (Aouani et al., 2014). In that case the cellular antennas will be most effective in terms of gain, bandwidth and directivity. References Aouani, H., Rahmani, M., Navarro-Ca, M., Maier, S. A. (2014).
