frekvenssiluuppiin
Frekvenssiluuppiin, also known as frequency hopping spread spectrum (FHSS), is a wireless communication technique used to improve the security and reliability of data transmission. In FHSS, the carrier signal hops or shifts from one frequency to another in a predetermined sequence. This hopping pattern is known to both the transmitter and receiver, allowing them to synchronize and decode the signal correctly. The hopping rate can be fast, with the carrier signal changing frequencies multiple times per second.
The primary advantage of FHSS is its resistance to interference and jamming. Since the signal is constantly
Another benefit of FHSS is its ability to mitigate the effects of multipath fading, which occurs when
However, FHSS also has some limitations. The hopping pattern must be known to both the transmitter and
In summary, frekvenssiluuppiin is a wireless communication technique that improves security and reliability by hopping the
