Next Generation Telecommunications Networks - Essay Example

Computer Communications and Networks Communication systems comprise of devices that employ either wired orwireless communication methods. They also involve other types of equipment, for instance, portable mobile radios, repeaters, and many other equipment. It also consists of a variety of accessories that include battery eliminators and enhancements. The enhancements involve data encryption, transformation of analog to digital communications, networking, and measures to curb online security threats. In a business setup, the communication system is set up to meet the information needs of the users. The motivation behind the creation of communication systems is due to the need for the improvement of transmission reliability. This is due to the reduction of errors in the process of sending and the reception of messages. Communications systems also increase the transmission capacity with the ability of sending large sizes of data in a single mode for a short time. In order to enable the exchange of information, there must be the transmission of the information from different devices, through a communication channel. There exists different communication media such as optical fiber and microwaves that possess unique characteristics for optimum performance. The integration of all the components of information technology forms a communication system (Beavin, p. 12). There are various requirements for computer communication. Such components include computer hardware. These are the tangible physical components of the computer. For instance, a Modem is one of the hardware devices that have the ability to send signals from one computer to another over telephone signals. This comprises of the computer inputs for communication purposes. The other component is computer software. This controls the computer operations, according to the instructions of the users. The software allows computers to interact with other computers through the management of resources. Some of the utility software contains language translators for easy communication between computers. Another component is the availability of a database. This is the storage of related data in an organized manner. This enables users to retrieve information when they require, for communication purposes. Through the Database Management System (DBMS), users have the ability to create, maintain, and access a database. The other component is the availability of a network. Computers have the ability to converge telephone networks, in addition to other networks of communication that use both data and voice for computer communication. Computers communicate through, small networks to large networks, such as the internet, where users converge. Telecommunication has various networks. One the networks include the transmission network. This carries different types of traffic that include voice, data, and video. It consists of optical fiber that has hundreds of multiplexers and travels for thousands of kilometers. There also exists switching networks that enables switching of data to the intended destination. The intelligent network contains a set of servers that consist of logic and data services. The access network enables the attachment of user equipment to the transmission network. Almost 80% of the compute users have embraced certain communication devices such as the Wireless Communication Interface Card. It enables a computer or other wired devices to have the access to a wireless network. Hubs and modems are the most common used communication devices, with over 90% of households possessing a modem. These devices convert digital signals to analog signals for connections over telephone lines. Wireless Transmission Media refers to the different methods that carry data through the space or air. Such methods include infrared, microwave signals, and radio transmission. Wired networks involve the use of cable in data transmission. Such cables include coaxial cables and the electric power wiring for home use. In addition, wireless networks utilize radio signals for transmission (Plevyak, Thomas, & Veli p. 15). Many users are finding better ways to utilize their communication devices in a convenient manner. People are investing in different communication networks that ensure the provision of reliability and security during data transmission. There are different options for communication solutions that include wired and wireless forms of communication (Beavin, p. 23). These two options have a market share in the utility market applications, but there is an increase in the use of wireless technology. This is because wireless communications are less costly as compared to the wired connections. Wireless communication is flexible in terms of mobility, where an individual has a connection wherever they are, in addition to advantages such as Bluetooth connections in sharing data and information. Wireless communication devices are easy to install as compared to the wired devices such as burying cables underground for connectivity. If there is damage to such cables, then it could take some considerable amount of time make replacements. This means that the cables need regular maintenance and monitoring. Such concerns raise the costs of wired connectivity and people are shunning it gradually. On the other hand, wireless connections require minimal maintenance and in case of a major problem, the system provides information for quick correction. Yes, it is possible to have a 100% wireless network. This is because three quarters of the users of wireless networks say that it is essential. The number of users does not matter, as they have a connection from any geographical location. For instance, most organizations that have installed wireless connections show an increase in productivity and profitability. The growth of the dependence in wireless connections is not surprising. This is because people have a constant connection through mobile phones that enables users to manage their tasks at their convenience. Through embracing wireless connectivity, there is a perception that different users keep up with the trends in the technology sector. In addition, internet providers are investing a considerable amount of resources in the installation of wireless communication systems. This is because of an increase in demand for wireless connections. However, 30% of computer users have had great concerns with their experience on wireless connections. This is because they complain of a poor network quality and claim that it is not reliable. They also feared on data security risks because attackers have the ability to tap data and information in the process of transmission. Work Cited Beavin, Nigel. Communication Systems.
