3 results about "Link margin" patented technology

In a wireless communication system, the link margin (LKM), measured in dB, is the difference between the receiver's sensitivity (i.e., the received power at which the receiver will stop working) and the expected minimum received power. A 15 dB link margin means that the system could tolerate an additional 15 dB of attenuation between the transmitter and the receiver, and it would still just barely work.
