Basic things about Wi-Fi and Mobile Communication Networks

Communication with no getting physically tied-up to cables has usually been of interest and mobile and wireless communication networks guarantee this. The last several years have witnessed unparalleled development in Wi-Fi communication networks. Important advancements have been made in the technologies that assist wireless communication environment and there is much more to arrive in the future. The products used for wi-fi communication need to have specific features that wired communication devices may not necessarily require. These features contain low power consumption, light weight, and globally communication capability.

In Wi-Fi and mobile communication networks, the easy access to a communication network is wireless so that the end consumers remain free to move. The others of the communication path might be wired, wireless, or mixture of the two. In basic, a mobile user, while communicating, has a wi-fi connection with a fixed communication ability and rest of the communication path remains wired. The range of wireless communication is always limited and consequently the range of user mobility is also limited. To overcome this restriction, the mobile communication environment has been created. In a cellular communication conditions, a geographical area is divided into smaller sized regions called cells, thus the name cellular. Every cell has a fixed communication device that provides all mobile devices within that cell. On the other hand, as a mobile unit, while in active communication, goes out of one cell and into another cell, service of that connection is moved from one cell to another. This is called the hand-off approach. The cellular option has many interesting features. As the cell size is small, the mobile devices do not require very high transmitting power to communicate. This leads to smaller products that take less power.wi fi communications

In addition, it is well known that the rate of recurrence spectrum, that can be used for wireless communication is limited and can therefore support only a small quantity of wireless communication connections at a time. Dividing communication regions into cells allows the use of the same frequency in various cells as long as they are adequately far apart to avoid interference. This raises the number of mobile devices that can be supported. Improvements in digital signal processing algorithms and quicker electronics have led to quite effective, smaller, stylish, and functional mobile communication gadgets. These gadgets have incredible mobile communication abilities, including wi-fi Internet access, wireless e-mail and news items, and wireless video (although limited) communication on portable devices. Wireless mobile phones are already available and work in different communication environments around the continents. The day is not far when a single communication number will be assigned to each newborn and will stay with that person no matter of his area.

Another field that is emerging fast is the field of ad hoc wi-fi communication networks. These networks are of a short-term nature and are established for a certain need and for a particular duration. There is no detailed setup required to establish these networks. As a couple of mobile communication devices come in one another’s proximity, they can establish a communication network between themselves. Standard cases where ad hoc wireless networks can be used are in the classroom environment, business meetings, seminars, disaster recovery conditions, for example. Once the require for networking is completely satisfied, the ad hoc networking method goes away.
