Wireless and Mobile Computing - Research Paper Example Additionally, Turisco and Joanna, internet refers to a global network which provides information access, as well applications, by use of a Web navigator or browser. Three Data transfer Options Turisco and Joanna reveal that, today’s market is features three commonly utilized method of data transfer; they include: i) Wireless Local Area Network (Wireless LAN) ii) Wireless Web or Wireless Internet iii) â€Å"Hot syncing† or Data syncing. Although this approach is referenced as a method of wireless data transfer, it is not ideally a wireless method. Data syncing uses docking stations or docking cradles, connected to a LAN in order to support data transfer between the device and the organization’s information system. Wireless LAN Matthew Gast, in his volume Wireless LAN, the term wireless LAN refers to a flexible communications and system of data communications, used, additionally, to or in place of a wired-oriented LAN. Turisco and Joanna, further, explain that, whi le featuring the Radio Frequency (RF) technology, the technology of wireless LANs receive and transmit data through the air. This approach minimizes the necessity of wired connections; the method, further, enables user mobility. Contrary to a number of other technologies, including as infrared, wireless LAN does not have to maintain the â€Å"line-of-sight† technology. Thus, the featured device can apply anywhere within the area of coverage. In a wireless LAN technology, the caregiver keys in data into a featured (handled) device including a Personal Digital Assistance (PDA), tablet, or laptop with a unique wireless LAN card. The card relays data in real time, by use of an antenna, using RF technology to a terminal of access, mainly connected to a wall or ceiling. For example, in a hospital setup, the terminal of access is connected to the LAN sends the requests for data or data received from the handheld information system to the information patient’s care information system. Additionally, data from the information system’s site can be relayed to the handheld system via the same technology. Wireless LAN’s indicate efficient application in the setting of a health care. Within the health care set up, the mobility area is confined within the organization or building; and the information necessary for system’s update can be immediately accessed. If the caregiver uses a relatively small handled device such as a PDA, such a small screen size suits the data viewing limitation, as well as the function of data collection. Tablets and laptops provide advanced capabilities of processing, more data storage, as well as larger display and thus users have access to entire records, as well as enjoy other privileges through the wireless connectivity. Wireless Internet A publication by Amjad Umar, Mobile Computing and Wireless Communications presents a discussion, that wireless internet (wireless Web) supports access data though mobile comput ing through the internet and particularly equipped handled devices. By using the latest PDA or a Web phone with the support of a micro browser, the user can, therefore, access display accessible data that can be accessed through the internet. From a technical explanation, the mobile device is connected to the systems cellular and thus can send requests to computer network (link) server. In this context, the server plays the role of a gateway, translating signals generated from the handheld devices into the signal language understandable by the Web, by use of an access as well as communication protocol. Wireless Application Protocol (WAP) emerges the leading
