Why Wireless


In the next few sections of the course we're going to look at Wireless Data Communications.
Although this is currently a small market when compared to the global Internet, it is growing fast. First we'll look at why we have wireless communications. We'll look at the main markets for wireless communications -who uses it for what. In the next chapter we'll look at some general characteristics of wireless data networks, after which we'll take a more in depth look at one packet based, wireless system, GPRS. We then finish off with a look at some other wireless systems.

The aim of this part of the course is to familiarise you with the terms and concepts used in wireless data communications, and to give you an idea of what it's being used for and why it is such an important market.
