Two Dimensions of WiMax Network

WiMax network (to compose) of two parts: the WiMax tower and the WiMax receiver. WiMax tower (to connect) directly to the internet backbone (to use) a wired connection such as optical fiber. It can (to connect) to the WiMax tower (to use) a line-of-sight link or a non-line-of-sight link. The line-of-sight communication (to involve) the use of fixed antenna or dish. This antenna (to fix) or (to deploy) on the rooftop or the tower of your building. Line-of-sight connection (to consider) as more strong and stable connection. Therefore it (to send) lot of error-free data over the network. It (to use) a frequency range of 66 GHz. Higher frequency (to decrease) the chance of signal weakness and interference and (to provide) more bandwidth. ...

Antennas

There were vast numbers of radio quanta in the universe long before Hertz performed his famous experiments. They are generated naturally whenever electric charges are accelerated or decelerated. All hot objects, in which charged particles are in rapid random motion, radiate quanta of radio energy, along with heat (infrared) quanta, and light too if they are hot enough. The stars are potent sources of electromagnetic energy, which is the basis of radio astronomy. On our own planet, atmospheric events such as lightning strikes produce showers of radio quanta, noticeable as the background crashes and crackles heard on broadcast receivers during thunder storms. In all but a very few of these cases of natural generation, the radio energy is incoherent, characterized by a jumble of quanta of very different energies. The same is true of many human-made sources of electromagnetic disturbances, such as electrical machinery and, in particular, the high-voltage spark ignition systems of petrol engines in cars and other vehicles. To terrestrial radio users, all of these just appear as noise, and their effect, if any, is harmful. ...
