Computer software is no longer a major barrier to widespread use of wireless information systems.

Introduction

To know about the connection of these topics it is must to know about the link between these phrases as well as the basic concept of these two. Firstly, to know what is computer software and wireless Information systems and then secondly to discuss their effects upon each other. Computer software is basically some programs or events that are written just to achieve certain functions by the software engineers.

Events are the set of steps that are written and combined to make a program. Now there arises a question that what is a program then the answer of this question is that: Programs are basically a set of rules and instructions on the basis of which a computer act to achieve certain functions. To perform a specific set of actions on computers intelligently or normally is the basic need to write a program.

Wireless Information systems are basically the systems that used wirelessly. What is “Wireless” and why and how question arises then? “Wireless”, as its name, shows that it means some sort of transport of data and information among wireless devices without using wires. It can be used in form of mobiles, PDA’s, and on large scale “Radio” is the example of it. Wireless information systems can be the range of mobiles, wireless devices, and networks. The device used for it is basically a device that is installed first and then it can be used. (Wireless network and information processing system, 2008)

Certain Dependencies

In case of Wireless information systems, there are certain dependencies. Among those dependencies some of them are very basic and are:
the mobility of the user mobility of the resource

Explanation

These dependencies can be differentiated in a way that in case of user mobility it can be in the form of traveling user whereas the case with the second dependency is that a network if created among multiple PDA’s and now in this case, if the PDA’s are moving. Along with this dependency, there is certain other as well. Just to be a focus on the actual behavior of the wireless and then wireless information systems only two are mentioned here to emphasize the main and important factors affecting the wireless in general.

Important features to consider about

There are certain tendencies that are important to know about these systems. According to these, Information systems have to develop first. While developing these systems a software engineer needs to know the protocols (specific rules of dealing on networks) and standard to follow up on them and then to develop finally (Feldman, 2007). There are certain standards that need to follow while considering wireless. In this way, there appears a need to select a standard according to the type of wireless information system. Those standards are as follows:
IEE802.11
IEE802.11a
IEE802.11b
IEE802.11g
IEE802.16
IEE802.16a
Open Air
Home based
Blue tooth based
Discussion

After implementation of these steps, architecture to develop a software program is required. When these wireless systems developed then these should cope with the problem fairly in real time. If an architecture of software program is designed in such a way that it is safe for security flexibility and other issues as well. If technology is implemented selected in an improved way then an information system can work well. If there are leaks in the design and programming tactics and technology implementation then there would be a lot of leak in the system as well that result in a very severe or drastic problem. In this way, it can say that software programs that developed to resolve a problem need attention in all these metrics to work upon and to get a better result. If there is a better program written by a programmer who is reliable and portable, efficient and of strong functionality then fulfill the better requirement in this case. Whereas if we are talking about the wireless information systems things become more sensitive as we are dealing on real-time and gather a lot of security risks. That’s why after applying and implementing rules and regulations and following the standards will get the better results.

The use of wireless information systems is beneficial for the companies and organization in various ways, first of all, it is accessible in minimum resources. It reduces the time and mobility issues problem and enhances the productivity of the organization in this regard.(Wireless Networking in the developing world session 2007)

The use of wireless management systems can improve the effectiveness of applying multiple procedures. An output of these procedures when resulted in a good form then increased or enhanced the productivity of the organization in a fast manner. Well, reputed industries, companies, and organizations are referring towards these wireless information systems that are very fast growing. Along with all this, there are still new advancements are just coming on the way to increase the quality of the projects or to attain the benefits of the technologies as much as it can be.
