Why attenuate a signal

However, amplification can also affect the noise in the transmission, potentially degrading the quality of the signal. Noise can come in the form of electromagnetic frequencies, electrical currents, wire leakage or wireless signals. Management of both attenuation and amplification is among the key skills and troubleshooting tasks of networking professionals.

Amplification can happen in a few different ways. Network or signal repeaters are common methods of amplifying signals. Repeaters take in the signal being sent, process it and then send out the signal stronger than before to the next waypoint either another repeater or the end user.

Another method is signal boosters, which are common with wireless signals. Antennas typically work well with, or are required for, booster equipment. Domain name system DNS amplification is another method, but this is typically related to network security systems and is used to amplify the signal to confuse a target server by flooding it with data.

A wide area network WAN is a large network of not tied to a single location. WANs allows devices from around the world to communicate and share information. A local area network LAN is a series of computers linked together to form a network in a circumscribed location. What are the types of NAT?

All networking and electrical cables give off an electromagnetic frequency within the cable or wireless vicinity.

Temperature, walls or other barriers, and wire insulation can all affect signal strength. Cold temperatures can cause wires to become brittle and inflexible, which can also slow down or attenuate the signal.

Hot temperatures can cause signals to overheat, potentially even catching fire if the outside plastic melts away and the inside wire is exposed to flammable materials. Either way, wire insulation and temperature control are important to preserve wire strength.
