Mobile phones have become as commonplace as pocket radios. No where will you go without finding someone with the palm tucked close to the ear receiving or making calls.
Mobile services differ greatly from traditional telephone services in many aspects. Here we try to look at how mobile phones work and how they are made and received calls.
The first thing you need to understand about mobile technology mobile phones are basically radio. All communication - that the device - travel along the line and he was obliged by radio transmission rules we have seen in the old Motorola two way radios sustavi.Jedina difference is that mobile phones can be applied computing concepts such as advanced networking and sophiscated programming into their functions and this is how we come to SMS messaging, conferencing, call waiting, and calendar features of the system.
The second concept is that cell. There is not one block of the network, but the city can be divided into several cells and cellular calls from one device to another holding in the hope along the cell until it gets to a predetermined number. The advantage of cells, is that it allows frequency reuse, which means that multiple users can use the same small cell and allows the company to use the same frequency over and over again, without locking resources for just one phone call. Typically, a cell covers about 26 square kilometers, and each has a base station that is just a tower and radio equipment for the control signals.
Of late, mobile technology is laden with computer applications. SMS and WAP access, for example, a typical computer applications have found their way into mobile functionality. SMS operates as a traditional mail system and server controls such as a network server. WAP dwells more about computer programming and is also under the control of the WAP server. When you send an SMS message, it travels over the wireless network and stored in a server and delivered to the recipient. The reason why this is purely an object of computer networks and independent of cellular service is that even while receiving calls SMS messages can get through.
WAP is the exclusive Internet driven services integrated into the cellular network to enhance the experience usually reserved for internet surfers. Examples of these objects are downloads and information services such as flight time and updates that are received from mobile operators via cell phone.
As mobile users grow in sophiscation, so that the technology that powers the device. Each new day we'll see what we can call the convergence of technologies allowing the other areas of communication will be gradually merged into mobile operations to provide customers with enhanced experience.
