Intergraph Solutions Group) The wireless technology is considered very quicker to be implemented in comparison to cable or DSL. No latency time is available for the conventional companies for cabling and building necessary infrastructure. Presently the commercial satellites are capable of providing complete coverage of the U.S. (Molenar, 1999)

The wireless instruments are capable of providing stock quotes, weather warnings, and burning news and also enable sending of short message services (SMS) among the mobile users. Location-based services are also being provided by some instruments that assists in finding out the actual location of the staffs. The benefits of the wireless technology are expected to be improved along with addition features as a result of development of more third generation networks and improved bandwidth. (Wireless Technology Overview: A White Paper. Intergraph Solutions Group). More inclination towards setting up of mobile computer laboratories with utilization of the laptop computers being equipped by wireless Ethernet Cards is being perceived. (Overview of Wireless Technologies) The dependence on the wireless technology is so acute that it will soon be impossible to think of the traditional environment without wireless technology. The World Wide Web showed the path for wireless technology and has radically transformed the methods of present day business. The potentialities of wireless technology are considered limitless and impelled the innovators to infuse more and more advancement in the fields.

Presently the Web applications have been estimated to have enhanced 500% since 1999 and presently having more than 600 million Internet users globally. The trend shows that about 61.3 million wireless instruments are to be used by 2005 for accessing the Internet. It will be customary that at least three wireless devices like laptops, personal digital assistants, cell phones are to be used by an average staff of the company. Several crucial aspects induce the movement in the direction of wireless technology. The first is provision of common reach ability to the information and applications. The mobility of the people has increased enormously and simultaneously the reach ability to the information also has increased than that of the past. However, the objective is to receive information instantly from everywhere. Further mechanization of the business processes is another motivating factor. (Wireless Technology Overview: A White Paper. Intergraph Solutions Group)

The crucial information is to be centralized and the roundabout processes are to be excluded. The organizations however, first need to give attention on improvement on ineffective business issues. The increasing popularity of wireless technology stems from the expediency of user, readiness and instant availability of the information and enhanced skill in business management. They always strive for more easy and instant methods of reaching to the information. To illustrate a businessman stranded at the airport find it curious to be connected and in touch with his office and required information. It is customary to access the information at more ease and instantly with the help of wireless devices like Black Berry RIM etc. The wireless technology is encountered a sort of excitement. It is generally mistaken to expect that wireless technology guarantees access of information at any time. Irrespective of the fact that the North America and Europe are sincerely improving and constructing a complete...

Moreover, no concern over the security of wireless data is another mistaken fact. Since the wireless network is radio based and uses air-waves its security is vulnerable to be broken at every moment. Some vehemently flaunt that the implementation of the wireless support is quite easier. This is considered correct to some extent however are based on the scale of the project. To illustrate implementation of the Wireless Local Area Network (WLAN) are considered very easy still deployment of this at the level of enterprise is considered much difficult. Practically, it is imperative that the implementation of the wireless technology in all the applications is neither feasible nor desirable. Taking into consideration the structural aspects the performance of some applications are considered weakened when transformed into the wireless technology. This is more particularly in case of legacy systems.

In reality, most of the applications presently structured do not take into account the wireless technology. Moreover, the persistent improvement in the wireless technological standards is considered another actuality. The development of technology continuously gives rise to change in the standards. It is significant to consider one or two standards at the moment of constructing the wireless technology of the organization however taking into consideration its flexibility with the possibility of its change in the future. Thus amidst much hue and cry in favor of wireless technology and its strengths it is hard to differentiate the publicity from actuality. The idea of integration of the wireless technology in the sphere of current architecture is found to be equally awesome. (Wireless Technology Overview: A White Paper. Intergraph Solutions Group)

Currently, the wireless technology has made some improvements in wiping out the complications inherent in the system so as to ensure its widespread adoptability. The complications involve discrete standards, low bandwidth and fixed and operating costs. The wireless systems are considered to back both institutional objectives and provision of cost effective solutions. The implementation of wireless technology is seen in interconnection of computers allowing remote management of data collection ensuring access control and security and also provides solutions to fit into the environments were wires are not desirable. (Overview of Wireless Technologies) Prior to planning for integrating the wireless technology in an organization it is first required to demarcate its expectations and to assess the return on investment and benefits one anticipates to receive.

For attainment of such objectives the companies involved in such areas utilizes their envision methodology in assisting the organizations comprehending their business and IT impetus for adoption of the wireless technology simultaneously identifying the key stakeholders and users estimate the project needs and fully become aware of the existing scenario. The most significant matter to be kept in mind is not to over structure the wireless solutions. Widespread application of the wireless technology in the concerned areas of operation is not advisable when the actual necessity is in respect of only a few. It is always worthwhile to begin in small scale and to supplement as and when the requirement increases. (Wireless Technology Overview: A White Paper. Intergraph Solutions Group)

2.1.1. Bluetooth

Bluetooth' was originally launched by L.M. Ericsson to integrate a telephone with other Internet devices, (Mobile Computing: Bluetooth Technology) and is being developed by PalmSource, the Company that developed the first infrared port for the Palm handheld computer, which enabled users to 'beam' information from one source to another with ease and speed. Whereas the Palm handheld device has to be essentially pointed at the device that is receiving information, the Bluetooth enables devices to remain in their original direction; they do not have to point at one another. Furthermore, the distance between the devices can be large, and the speed at which the information can be transferred is much higher. The data itself can be encrypted and therefore secure. In essence, the Bluetooth is the latest and fastest and also low cost mobile Internet device that is easily affordable by the general public. (Bluetooth Wireless Technology)
