Question: Discuss about the Wireless Technologies for Today Businesses. Answer: Introduction The development of wireless network technologies has put positive influence on network users. In past days, antenna was considered an appropriate method for data transmission through signals. Nowadays, this method of networking is also used with its different types such as Yagi, Horn and Cellular and others. Moreover, various other wireless techniques are also available such as CDMA and FDMA. The purpose of making this report is to discuss these network technologies in detail with its strengths and weaknesses. These antennas are commonly known as Yagi-Uda antennas. These are mostly used in ham radio, television reception and bridge antenna to connect a site to access point of Wi-Fi. If I talk about strength factors of Yagi then it can be said that these are directional antennas and mostly focus on all its input in single direction. This feature of Yagi makes it ideal to receive low level strength signals. Moreover, high gain of these antennas provides good range to them. Another strength factor of Yagi antennas is its filters that are capable to filters all noise signals that come from opposite direction (Radio-electronics.com, 2017). Due to this amazing feature, Yagi antennas are considered most useful in high demand applications like telecommunications. On flip side, the key weak factor of Yagi antennas is its limited bandwidth. However, to get high gain level, antenna should be lengthy (TurboFuture, 2017). This type of antennas are known as most widely used microwave antennas. For directing radio waves in a beam, horn antennas consists of flaring metal waveguide. Moreover, horn antennas have coaxial cable that is attached to sides of these antennas. The main strength factor of horn antennas is that it can work easily over broad bandwidth. Besides this, these antennas have significant level of gain, directivity and these are easier to adjust and construct. On contrary, these antennas have a weak point that major fluctuations are found at low frequencies while using these antennas (prezi.com, 2017). To wide range and reliable networks to all network users, cellular antennas are used. By cell phone companies many towers are required to place at potential places. It is a best way to provide good signal range to all network users. The main strength factor of this type of antennas is that these provide best service in less expenses. On flip side the weakness of these antennas is that it may cause long term health risks for people living near the cell tower. However, medical communities are working on this to resolve this problem (Techwalla, 2017). Among above discussed types of antennas, I opine that cellular antennas are better because it can serve maximum number of people with a strong network. Compare and Contrast CDMA and FDMA CDMA stands for Code Division Multiple Access. In this multiplexing technique, there is limitation on time and frequency. Moreover, similar communication without collision and entire bandwidth can be used. Besides this, users are divided by code in this technique not by time slot and frequency slot. The crucial features of CDMA enhances its usage among its users that includes no requirement for network timing, no limitation for baseband type and availability of simple algorithm (IT Answers, 2017). FDMA stands for frequency division multiple access. In contrast of CDMA here division is done on the behalf of the frequency not code (Careerride.com, 2017). Under this technique, frequency band is allocated into channels for wireless cellular telephone communication. Furthermore, FDMA allows several users to share a single radio frequency. There are some main features of FDMA that include low overhead, simple hardware usage, no timing issues and simple hardware at mobile unit (Singh, 2017). CDMA FDMA In this, narrowband signal is combined by wideband signal that is known as codeword. In FDMA, bandwidth channel is narrow and it is known as narrowband system. Under this technique, concurrent transmission occurs (Khan, 2017). Here when channel is not used then channel remains idle. In CDMA separate pseudo-code is used. In FDMA, no pseudo code is required. These are some essential differences among CDMA and FDMA and these techniques are used according to requirement of users in different fields. Recent Advanced Wireless Technologies After discussing about traditional wireless technologies, in this segment of report I would like to discuss some recent advanced wireless technologies that are WiGig, Blutooth Smart and Apple iBeacon. This wireless technology is commonly known as technical spec 802.11 and it is a latest protocol of Wi-Fi. Nowadays, it connects up to 1Gbps through 40GHz radio band and in future speeds will be increased up to 10Gbps (Brandon, 2017). The strength of WiGig is that it provide very high speed wireless. The weakness of this recent technology is that it is not reliable as our Wi-Fi, so replacement is not suggested (Bradley, 2017). This emerging technology is a short-range wireless technique and it is more beneficial than conventional Bluetooth. Unlike traditional Bluetooth, Bluetooth Smart does not send a constant signal that saves power consumption. The less power consumption is the main strength factor of this wireless technology. The weakness of Bluetooth Smart Technology is related to its less security in case of sending most confidential information over network. However, developers are finding solutions to resolve this issue. This recent technology is actually a retail oriented use of Bluetooth Smart Technology. This technology relies on Apple technology for transmitting signals from iphone or ipad. The strength factor of this technology is that it is able to transmit retail regarding deals to iOS Devices. The weakness of this new technology is its weak signals and low coverage. These above discussed new technologies can be used in different fields according to requirements of its users. But as per as my views are concerned, Bluetooth Smart will be dominant player in future because it has good response from its users and it is able to provide better services in future at large extent. Conclusion To conclude, it can be said that over the time various advanced technologies are coming in field of wireless networking and with the help of these techniques network users can get various benefits as we have discussed above but they need to select effective technology among them.
