The internet plays a very important role in every sector today. This is because it has revolutionized the way we communicate, interact, and operate. There are different ways through which it is provided to the consumers. One of them is via satellites. The Internet that is provided in this way is known as satellite internet.
It is provided to the consumer through Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) satellites. LEO satellites are preferred because they can reach all parts of the earth, unlike the geostationary ones which cannot transmit signals to the Polar Regions. Geostationary satellites also have high latency which causes significant delays in communication and data reception. On the other hand, LEO and MEO types have little latency but transmit signals at lower speeds.
Due to these setbacks, engineers are designing ultralight atmospheric aircraft to replace the satellites. These are gadgets that fly about 20,000 meters above the ground. They have solar panels on their wings which ensure that the computers onboard have a constant supply of electricity during the day and night. Signals from the ground are relayed to and from the aircraft. This reduces the distance the signals cover during transmission which in turn greatly reduces the latency.
Signal transmission is normally affected by moisture and other types of precipitation. High-frequency signals are more affected than low-frequency signals. Therefore, low-frequency signals are used in tropical regions that experience heavy rainfall. However, if high frequencies are to be used, techniques such as rain margins and adaptive uplink power control can be used to strengthen the signal.
The operation of satellites mainly relies on the line of sight. There should be a clear line of sight between the dish and the satellite. Obstructions such as vegetation cover, buildings, and any other type of obstruction reduce … Read More
