function Beam Technology WHY SPOT BEAMS? Spot beams load down send offs to the next level. Spot beams enable EchoStar to yield more local channels to item, precisely defined areas, better its ability to argue with cable beamers. Echo I through and through Echo VI satellites use beams that cover the entire nation. To volunteer local broadcast coverage, channels intended for only one and only(a) local trade are scrambled so customers elsewhere cannot view them. The impertinent sleep with beam satellites are knowing to aim accredit beams at selected metropolitan markets, allowing the similar wireless frequencies to be re employ in different cities, so increasing the channel capacity. For example, by centering over a very small area, like the spick-and-span York City metropolitan area, the frequency can be reuse in some(prenominal) other places like Miami, San Francisco and Chicago (these cities are used as examples, and will not actually share the same blot beam frequency). EchoStar VII and EchoStar VIII are both spot beam satellites. Why do these benefit our customers? With these devil passing powerful spot beam satellites, we can draw rough 50 different spot beam projections to the Continental U.S. and expatriate a lot more local scheduling to those specific areas. Each spot beam has an approximate diam of three hundred miles, making them powerful satellites!

FREQUENCY TYPES: Frequencies Explained: When program from our capacity providers is send (transmitted) to the satellites from one of the uplink centers (Cheyenne, WY or Gilbert, AZ), the transmission uses a uncomparable radio frequency (RF) channel. ! It is similar to relations thoroughfares on a highway. Each RF channel represents a traffic lane that keeps the signals (vehicles) from interfering with one another en lane to the satellite (this is also called uplinking). Unique frequencies are also used to downlink programming from the satellite to the customers homes. The satellites transponders stupefy signals from earth on one frequency and attach and transmit them...If you want to get a full essay, request it on our website:
