Communication without being physically tied-up to wires has always been of interest in addition to mobile in addition to wireless communication networks promise of which. The last few years have witnessed unprecedented growth in wireless communication networks. Significant advancements have been made inside technologies of which support wireless communication environment in addition to there is actually much more to come inside future. The devices used for wireless communication require certain features of which wired communication devices may not necessarily need. These features include low power consumption, light weight, in addition to worldwide communication ability.
In wireless in addition to mobile communication networks, the access to a communication network is actually wireless in order of which the end users remain free to move. The rest of the communication path could be wired, wireless, or combination of the two. In general, a mobile user, while communicating, incorporates a wireless connection using a fixed communication facility in addition to rest of the communication path remains wired. The range of wireless communication is actually always limited in addition to therefore the range of user mobility is actually also limited. To overcome of which limitation, the cellular communication environment has been devised. In a cellular communication environment, a geographical region is actually divided into smaller regions called cells, thus the name cellular. Each cell incorporates a fixed communication device of which serves all mobile devices within of which cell. However, as a mobile device, while in active communication, moves out of one cell in addition to into another cell, service of of which connection is actually transferred coming from one cell to another. of which is actually called the handoff process. The cellular arrangement has many attractive features. As the cell size is actually little, the mobile devices do not need very high transmitting power to communicate. of which leads to smaller devices of which consume less power.
In addition, of which is actually well known of which the frequency spectrum of which can be used for wireless communication is actually limited in addition to can therefore support only a little number of wireless communication connections at a time. Dividing communication regions into cells allows the use of the same frequency in different cells as long as they are sufficiently far apart to avoid interference. of which increases the number of mobile devices of which can be supported. Advances in digital signal processing algorithms in addition to faster electronics have led to very powerful, smaller, elegant, in addition to versatile mobile communication devices. These devices have tremendous mobile communication abilities including wireless Internet access, wireless e-mail in addition to news items, in addition to wireless video (though limited) communication on handheld devices. Wireless telephones are already available in addition to operate in different communication environments across the continents. The day is actually not far when 1 communication number will be assigned to every newborn in addition to will stay with of which person irrespective of his/her location.
Another field of which is actually emerging rapidly is actually the field of ad hoc wireless communication networks. These networks are of a temporary nature in addition to are established for a certain need in addition to for a certain duration. There is actually no elaborate setup needed to establish these networks. As a few mobile communication devices come in one another’s proximity, they can establish a communication network among themselves. Typical situations where ad hoc wireless networks can be used are inside classroom environment, corporate meetings, conferences,
disaster recovery situations, etc. Once the need for networking is actually satisfied, the ad hoc networking setup disappears.
