Mobile Communication Devices

There are several types of mobile communication devices that are in use today. Among these, the cell phone is the most common. Cellular phones were created as a replacement for the traditional fixed line phones and wireless phones. On the one hand, these phones worked by transmitting signals down PSTN lines, thus requiring a lot of investment in terms of infrastructure in order to be operational. Cellular phones, on the other hand, are supported by cell towers which are strategically located. Though it was an expensive venture when it was first introduced it has, over the years, become much cheaper, largely due to the advancement in technology and the wide acceptance that the technology has received from consumers. Cellular phone technology has been used as the basis for the development of most of the mobile communication devices in existence.

The Smartphone is an example of a mobile communication device that is based on cellular technology. This basically is an advanced form of the initial mobile phone, which was created to send and receive text messages, as well making and receiving calls. The smart phones are capable of doing this - and more. They can be used to browse the internet, send and receive email, run important applications such as word processors and run multimedia applications, among other functions. Some of these smart devices have a full QWERTY keyboard similar to that of a computer, to make them more convenient for users.

Due to the power that is possessed by smart phones, there was a need to expand their functionality to include the hottest trends in technology - touch screen technology. This gave birth to the touch screen phones, which are basically smart enabled devices with the added advantage of having a touch sensitive screen, which is used for inputting commands. Touch screen technology is probably the latest as far as input devices are concerned. This is a technology that has been received well by consumers; and it is no wonder that the manufacturers of the different devices are all making an extra effort to incorporate this technology into their devices.

The need to have a powerful mobile communication device that incorporates the latest technology saw the creation of the tablet. This is a cross between a smart mobile device and a personal computer. As such, the device comes with the specs of a normal computer, in terms of processor and RAM, as well as the normal features of a cellular phone, such as being capable of making and receiving calls, SMS texting and the like.
