How far can we communicate in space?
Ground station antennas range from the small very high frequency antennas that provide backup communications to the space station to a massive, 230-foot antenna that can communicate with far-off missions like the Voyager spacecraft, over 11 billion miles away.
What is the range of MAN network?
MANs typically cover transmission ranges between 5 and 10 km in diameter and may cover an area the size of a city, or even a group of small buildings. MANs often act as a high-speed network that allows sharing of regional resources and also provide a shared connection to other networks.
What is the maximum distance covered by LAN?
A LAN network is limited to between 100-1000 meters coverage. A MAN network is will usually stretch up to an area of 100 KM.
What is used for long distance communication?
The equipment for long distance communication is very important. Communication takes place either through heliograph signaling using a flashing mirror, electrical lamps, spot lights, colored disks, etc., or it is accomplished electrically by radio or by wires within the confined areas of the space station.
Will Voyager 1 ever stop?
How long can Voyager 1 and 2 continue to function? Voyager 1 is expected to keep its current suite of science instruments on through 2021. Voyager 2 is expected to keep its current suite of science instruments on through 2020.
Is MAN faster than LAN?
MAN is the abbreviation for Metropolitan Area Network and bigger than LAN network. MAN’s data transmission speed is 5-10Mbps, which is faster and more expensive than LAN but slower and smaller than WAN.
How many computers can be on a LAN?
The smallest LAN may only use two computers, while larger LANs can accommodate thousands of computers. A LAN typically relies mostly on wired connections for increased speed and security, but wireless connections can also be part of a LAN.
What is the most common type of LAN?
The most widely used LAN technology is the Ethernet and it is specified in a standard called IEEE 802.3. (Other types of LAN networking technologies include token ring and FDDI.)
Why did NASA need a long distance communication system?
Communicating across great distances has always been a challenge. So when NASA engineers designed the Lunar Reconnaissance Orbiter (LRO), they knew it would need an extraordinary communications system.
Which is better for long distance data transmission?
It’s ideal for sending large amounts of data over a long distance because it provides more power and more efficiency than its alternative, the transistor amplifier.
How big should the BLOS communication channel be?
A comparison of a proposed system to the capabilities in the specification sheet of the PRC-117G provided in reference 1 is desired. The BLOS communication channel should be able to cover a distance much greater than the LOS horizon of approximately 35nm.
How are microwaves used for long distance communication?
The device uses electrodes in a vacuum tube to amplify microwave signals to high power. It’s ideal for sending large amounts of data over a long distance because it provides more power and more efficiency than its alternative, the transistor amplifier.
