Advanced Wireless Communications Networks - Essay Example

Advanced Wireless Communications Networks Advanced Wireless Communications Networks Wireless communication networks move data from one location to another without electrical cables. Depending on the strength of the network machinery, the distance between both locations can be lengthy or short. Data moving from place to place without artificial conductors is regarded as wireless, which is a subdivision of telecommunications. Advanced wireless communications networks have many uses in contemporary society since they slowly replaced wired networks over the past decade. Numerous new applications such as smart gadgets, wireless sensor grids, and distant telemedicine are surfacing from study concepts to real networks. In formal settings, the explosive growth of wireless networks arrived along with the proliferation of laptops and tablets, which proposes a promising future for wireless communication networks. The following paper discusses the use of wireless communications networks in formal settings such as offices. First, wireless communications networks are economic to install in offices today (Zhu and Li, 2013). Advanced wireless communication networks have undergone numerous changes because of investments in research, competition, and recurred obsolescence. Unlike wired communications, wireless communications networks only need transmission, serving, and routing ports and stations. Wired networks need costly wires, labor for installing these cables through tight channels, buying identical socket faceplates, buying gear and physical solutions for cable maintenance or troubleshooting. With wired communications, offices have cable clutter connecting servers and desktops from cubical to cubical or from maintenance rooms to the roof of the building. Clutter can be dangerous for employees within a formal setting because it can trip a person or wear away and shock a user touching it with naked hands. Secondly, wireless communications are safe. Wired communications networks that employ incredible 1,024-bit encodes will require an entire human generation to recover data that was destroyed. On the other hand, wireless communications employ 802.11x networking, which is a sufficient solution for an ordinary formal setting (Zhu and Li, 2013). Such networking rates today can replace wired communications networks in offices. As wireless communications continue to advance in terms of speed and coverage, wired communications networks will become obsolete soon. The function and architecture of wireless technologies involved in wireless communications determines the most suitable formal setting. For instance, an office can apply wireless LANs through radiated media like broadcast, microwave, satellite, spread-spectrum, or infrared radio. Formal settings that work within their premises, normally short distances, can employ radiated media for short distances such as broadcast radio. Broadcast has a radio frequency that ranges from 500,000 Hz to 108 MHz, which formal settings seldom use (Glisic, 2005). On the other hand, satellite radio are the most effective in terms of bandwidth because of their location and geosynchronous nature. However, few organizations worldwide can afford direct access to such wireless communication systems. Even though spread-spectrum wireless communication technologies are the most affordable and excellent radio, formal settings cannot rely on them since they were made initially for military use. This leaves LANs for business applications the most fitting wireless technology for offices. Contemporary organizations exercise mobility that has raised the demand for wireless communications systems (Ren, Cai, & Su, 2012). With globalisation nearly at its peak, wireless communication networks are needed today more than ever. The rising demand for wireless communications today originates from the burst of wireless devices, cheap instant messaging services, a demand for instant email services and access, and the rising modification of data services. As the desire for these features keeps on rising, the need for wireless communications continues rising correspondingly. Sightlines, topography, and environment have vital functions in a wireless communications network. More specifically, lines of sight have to be away from vegetation, buildings, and other obstacles for ultimate transmission. Equally important is weather for connections at 38GHz and exceeding three miles while there is heavy rainfall (Ren et al., 2012). Wireless communications networks offer great integration advantages to companies looking to install the most recent communications solutions. Reports on TCO (Total Cost Ownership) by organizations that use advanced wireless communications networks indicate a great improvement in communications standardization and incorporation within and outside their formal premises. For instance, Citigroup, a huge Fortune 500 bank released a report about its renovation of communications networks in 2013 (Zhu and Li, 2013). With one headquarters dealing with many branches situated across the United States, Citigroup has over 5,000 workers with tremendous office space. Its wireless communications partner, Cisco, provides Citigroup with the overall advantage of integration that results in a nearly 50% decrease in TCO as returned within five years. Fourthly, in terms of security, wireless communications network can compromise an organization because of intruders from outside their formal settings (Zhu and Li, 2013). If a wireless communications provider installs a grid incorrectly, communications gurus can tap into this grid irrespective of how advanced it is. In addition, non-encoded wireless networks enable outsiders to effortlessly tap into the traffic and possibly read data contained within connected servers. Even though the same logic is applicable to wired communications systems, physical access to the building is mandatory. In both cases, request level security and encryption is vital. It is often not important whether an outsider is tapping into an organization’s wireless communications system if employees’ communications client and servers are encoded (Ren et al., 2012). Working as a junior technician at a local IT store taught me about the technical and incorporative disadvantages of wireless communication grids. I was able to tap into the store’s internal traffic using my tablet when I was free. This intrusion allowed me to just see but not edit or write data within emails sent between and among all staff members, including the store manager and the headquarters. I used the store’s wireless communications system, which Verizon provided and installed. Through this grid, I simply ticked one check box in the Settings window for Microsoft Outlook on the main server in the store’s maintenance room. Without the appropriate configuration, any network is vulnerable to eternal compromises. My intentions were to check just how secure the store’s wireless communications grid was and I confirmed that it was weak. For a wired store or premise, computers and servers are controlled directly by the network administrator, making the general attitude towards wired communications systems favorable (Ren et al, 2012). Desk reality is an important factor for formal settings that wireless communication systems fulfill. Offices that have much less clutter are tidier and favorable for work considering additional space is necessary for accommodating other things such as documents (Ren et al., 2012). Wireless communications technologies such as 802.11x are most suitable for such situations since no cables connect desktops to printers, fax machines, PDAs, and even speakers. As a result, employing the 802.11g technology integrates profound flexibility and ease for an organization (Glisic, 2005). This means the organization no longer needs details about the location of desktops, faxes, printers, and servers on their respective office floors. Wireless communication systems make work efficient by enabling users to move around the office with their laptops, smartphones, or tablets with ease. In the process, sharing and presenting documents as projects help with conferencing or debates amongst employees or with clientele. In a shared office or cubicle isle, one wireless node can convey data with hundreds of gadgets at the same time (Zhu and Li, 2013). Consequently, office and furniture ergonomists get a better idea of how to design wirelessly networked components of a typical office in any place within a given range or access point. In conclusion, wireless communication networks are suitable for formal settings in a world of peaking globalization and wireless devices. More specifically, wireless LAN meets the needs of many formal settings today in contrast to other types of wireless communications systems such as satellite, infrared, and broadcast radio. Many offices value space and would prefer wireless communications to increase space and reduce clutter significantly. As a safety measure, organizations today employ wireless communications networks to reduce the health expenses incurred from damage to employees caused by cables. Wireless communications may be more vulnerable to external intrusion, but closely monitored security systems and configurations can assure the security of client emails, server data, and instant messaging content.
