Essay: Requirements of Software
WLAN 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 point technology of Airespace, putting Cisco “in the driver’s seat for enterprise-grade wireless.” Other networks are also in work: “While not as big, but leveraging the benefits of thin access points are Aruba Wireless Networks and Trapeze Networks.” (Gilliot, I.)
Developers of software for mobile internet devices face constraints from the limited memory space and processing power available for the application. The display screens of mobiles are also very small and so there is very little information that can be made to appear on the screen at one time. Developers who may be used to working on large computer systems may find it hard to work with such limited power of the device. Besides the device the software is being designed for, there are limitations of the wireless environment as well. “Wireless networks are unreliable and expensive, and bandwidth is low. They tend to experience more network errors than wired networks. The very mobility of wireless devices increases the risk that a connection will be lost or degraded.” (Mahmoud, K. H. andLorainN., May 2002)
