Perceiving the constantly accelerating pace of technology adoption, one is forced to believe that wireless technology will fast replace the wired world. However, despite apparent advances in wireless technology, many are skeptical about its future with respect to the complete replacement of wired communication. Many IT specialists believe that the major barrier to the spread of wireless networks will be the little amount of innovation and investment in the industry of wireless systems support software (Orr, K., December 2001). However, many believe that organizations may be slow in responding to the growing needs of software for wireless systems, but they are not oblivious to them. Software development programs are being initiated by a number of companies to support wireless systems. Cutter Consortium conducted a survey in which 37% of IT professionals said that their companies were planning to develop wireless applications (Orr, K., Dec 2001). Therefore, we hope that in due time, there will be many issues regarding software support to wireless systems. The developers are only busy with that how far this technology will go and how big the market for its software will be in the future. The first example of the wireless technology that comes to one’s mind is the cell phone technology, and perhaps it is one of the most widely used network technologies in history. Cell phone networks make use of GSM and CDMA technologies in most countries. Mobile internet devices also include Personal Digital Assistants (PDAs). Wireless Local Area Networks (WLAN) is a relatively recent technology. In our paper, we will concentrate on the applications and operating software used by mobile networking devices and WLAN. Wireless Systems and Software used WLAN is a technology that allows people in a limited geographical area to be linked to each other, just in the way a normal Local Area Network or LAN works – the only difference is that WLAN is wireless. WLAN could be used in organizations to interconnect the entire organization. We see examples of WLAN in shopping malls and hotels where hotspots or Wi-Fi systems allow people in the area with appropriate devices and software to access the services of the internet through this WLAN. As Goth (2006) notes, “In mid-August, Google launched Google Wi-Fi, a free wireless network for users in the city of Mountain View. In early September, a consortium including IBM, Cisco, Azulstar, and SeaKay won a contract for a 1,500-square-mile network intended to serve 42 entities and 2.4 million people in Silicon Valley, including every city in both San Mateo and Santa Clara counties.” Software for mobile devices is more difficult to design because it will be developed and tested in a totally different environment, i.e., Solaris or MS Windows machine, from the one it will eventually be run on. Applications can be developed in several environments, for example, J2ME Wireless Toolkit. Software to download applications on cell phones includes Motorola iDEN Update Software Application/Java Application Loader. (Mahmoud, K. H. and Lorain N., May 2002). LLAN technology requires both operating software and applications. These applications must provide the system with security as well as efficiency. Thick and thin access point wireless solutions are provided by Cisco. They have recently acquired thin access poi
