Disadvanages and advantages of wireless technology

Introduction

Wireless technology has reached every shpere of life i.e. in hospitals, hotels, suites, etc. They are already in the hands of delivery people, equipment, installation, insurance agents, brokers, doctors and pharmacists. In its simplest form, wireless data is transmission between devices that are not physically connected. These devices can be either from a personal digital assistant (PDA), for a laptop, two-way pagers, global positioning satellite (GPS) antenna, the remote control sensor. The communication can occur at short range using infrared technology, the broader the range, using high-speed wireless LAN within a building or extraterrestrial distances using satellites.

Wireless technology to provide mobile professionals and end users to access information anywhere. It facilitates information sharing and cooperation, where physical co-location is not possible. And wireless technology has long contributed to tracking, detection and management of securities, movable assets, such as cargo containers, laboratory equipment, and even taxicabs. (Karygiannis, 102)

All wireless technology is based on mobility. Nevertheless, people often confuse the terms "mobile" and "Wireless". Mobile workers, devices and applications that do not necessarily use the wireless capabilities. Many mobile users laptops to rely solely on Dial-Up connection for download and upload data, as well as the CPC is valued primarily for their information the organization. In addition, the mobile is not a prerequisite for the use of wireless technologies. Office workers can use wireless LAN as part of their work, and, perhaps, and receive calls on a mobile phone while on the desktop.

At this time, the number one wireless applications is the voice - telephone calls using cell phones. This application does not have much impact on the IT organization itself. However, growing demand for wireless data applications, as well as the forthcoming construction of wireless networks to better support these applications, the promise to create a wireless craze within IT organizations in the next few years. (Elliot, 62)

Potential for transmission of data through wireless applications are endless. Branches of innovative wireless efforts include transportation, medical and financial services. In the transport sector is the use of wireless data applications to monitor and transmit the shipment status. Bar-code scanners, computers, dashboard, as well as satellite communications will enable real-time track individual packages. In the healthcare industry, administrative personnel, the use of wireless LANs for the reception of patients, ER physicians to use PDAs for the consideration of the patient and laboratory results, and physicians use e-prescription applications for checking drug doses and transmit prescriptions directly to pharmacies. Brokerage firm to the stock signals and the order of confirmation of their customers wireless handheld devices. (Mohan, 121)

Wireless implementation within the organization can run the entire spectrum from simple to complex. This may mean installing a wireless network in key areas such as conference rooms and training centers to give employees access to corporate intranet and e-mail program without having to worry about connecting devices. This may require the installation of infrared technology to enable short-range synchronization of data between the device ...
