CASE 3 – SAIC, Hewlett-Packard, GE, and Others: The Business Case for Wireless Sensor Networks
1. What are some of the benefits associated with using wireless networks to collect and transmit data?
Wireless networks are basically a type of computer networks that is not connected with wires. These types of networks are associated with a telecommunication network whose interconnection is implemented without the use of wires. Wireless telecommunication networks are usually implemented with some type of remote information transmission system that rely on radio wave, microwave, infrared, and visible light pulses to transport digital communications. There are various types of wireless technologies that include terrestrial microwave, communications satellites, cellular and PCS telephone and pager systems, mobile data radio, wireless LAN’s, and other wireless Internet technologies.
The choice of technology depends on the specific ranges within the electromagnetic spectrum of electromagnetic frequencies that are specified by national regulatory agencies to minimize interference and promote efficient telecommunications. Wireless networks have had a significant impact on the world business. Information could be sent overseas breaking geographical barriers in a faster efficient and reliable way.
2. What are some of the challenges faced by this use of wireless technologies? What solution can you offer?
The first challenge faced by the use of wireless technologies is that they need to figure out how to organize these systems and develop interesting applications for them. The next challenge is in writing the software to make it is easy to communicate between sensors and killer apps.
For this reason, telecommunications manufactures and national and international organizations have developed standards called protocols and master plans called network architectures to support the development of advanced data communications networks." A protocol is a standard set of...
