Because Pikeville Cable (like DSL) only sends signals where they need to go, and it travels along a contained wire, it is much more energy efficient that other technologies where the signal radiates through the air. This leads it to possible cost reductions in terms of both the actual electricity used, as well as the physical systems that do the transmission. This is especially important for 2-way communications where the receiver sends data back to the transmitter (which happens when you browse the internet, for instance, or perhaps when a pay-per-view broadcast is selected). In addition, since the signals don’t have to go all the way into earth orbit and back the way they do with satellite broadcasts, the time taken for a signal to go back and forth can be much shorter. The latency of sending a pulse of data back and forth over a satellite link is inevitably quite high even though the signal travels at the speed of light (about one quarter second each way from transmitting station to home, or vice versa). This is a long time for interactive applications. Satellite TV Satellite television, on the other hand, requires less physical infrastructure on the ground. You don’t need a huge network of wires spanning the countryside. You do, however, need launch capabilities and ground stations. The satellites themselves are very expensive to deploy, although they have gotten larger and cheaper as the technology has developed. The fairly recent Anik F2 had a weight of 5900kg (13,000 lbs), as opposed to INTELSAT I, the first geosynchronous satellite (launched in 1965), who’s weight was only 68kg (150 lbs). In the end though, the competition between satellite, cable and terrestrial broadcasting may depend on geography and consumer ease-of-use and convenience rather than hardware costs or power needs. It seems like in many cases, ease of setup per household trumps energy efficiency, latency, and even cost, since satellite broadcasting is the preferred solution for a huge fraction of the population. Satellite technology When satellite technology was initially developed, both the transmitter and receiver required a very large and expensive dish antenna to operate. As the technology has matured over the last half century, every aspect of system has improved, but the most striking change has occurred in the receiving dish antenna. Instead of being a huge disk, satellite dishes for receiving transmissions can be as small as 12 inches (18 cm) in diameter for television: the size of a medium pizza (although 18-inch dishes (45 cm) are typically the smallest in commonplace use). These can be even smaller for radio-only broadcasting, and of miniscule size of the reception of satellite- based Global Positioning (GPS) signals. The GPS has become the importance technology for many Pikeville Cable service companies. Author Resource: The Author Jeson Clarke is conveying information about Pikeville phone service .
