mobile computing
Technology gives us power, but it does not and cannot tell us how to use that power. Thanks to technology, we can instantly communicate across the world, but it still doesn't help us know what to say.
-Jonathan Sacks
Through the evolution of technology we have been able to create devices that are able to do computations without needing to be in a fixed location. Mobile computing devices can do the work of general purpose computers (laptops), voice data communication (cellular phones) and media consumption (tablets and laptops). From the last example we can see that mobile computing is not restricted to the device. Mobile computing can be defined as the ability to do computations from a device that is not at a fixed location.
While it is possible to do some computation on many of the above mentioned types of devices, the wide range of services they provide would not be possible without the communications technologies which have evolved to meet their [the computing devices'] needs for wireless communication.
The development and continued, concurrent evolutions of mobile communications technologies through wireless data transmissions media has created the possibility and continued viability of mobile computing technology. The dominant communications medium is radio frequency. Through using various radio frequencies transfer standards (data transfer speeds) such as 4G, 3G, EDGE, WiMax or Wifi and radio frequency bands such as 850 Mhz, 900 Mhz, 950 Mhz and 1800 Mhz among others, we have been able to use communications technology while mobile. For a look at frequency bands around the world please see here.
The advent of mobile computing has allowed us to make great advancements in the type and quantities of data that we can process and also access at any given moment but this has not been arrived at without risks, we've had to take the good with the bad.
