What is the meaning of radio technical terms ?

Below some technical terms that any radio engineer shoud be aware of :

  1. Signal strength

Signal strength is a measurement that expresses the quality or value of a particular signal at a certain distance from its source

2. SNR

Signal-to-noise ratio, often written S/N or SNR, is a measure of the strength of the desired signal relative to background noise that affects it (undesired signal).

3. Jitter

Jitter is a phenomenon in which data packets are delayed in transmission due to network congestion or, in rare cases, route modifications. This is frequently the source of buffering delays in video streaming.

4. Latency

The time delay between an action and a response to that action is known as latency. It is the time that has gone from the time a packet is delivered from the source to the destination and the time it takes for the acknowledgment from the destination to reach the source in the realm of networking

5. Rx Sensitivity

Measurement of the weakest signal that a wireless receiver (UE) can receive to decode the data and get the content of it. Received sensitivity is affected greatly by a number of factors such as location, place of the the terminal

6. BER

it Error Rate, BER is used as an important parameter in characterising the performance of data channels. When transmitting data from one point to another,percentage of bits that have errors relative to the total number of bits received in a transmission

7. Diversity

Diversity scheme refers to a method for improving the reliability of a message signal by using two or more communication channels with different characteristics

8. MIMO

Multiple-Input Multiple-Output abbreviated as MIMO, is a wireless technology that increases the data capacity of a RF radio by using multiple transmitting and receiving antennas

9. Fading

Fading refers to the attenuation of the transmitted signal power due to various variables during wireless propagation. These variables can be atmospheric conditions such as rainfall and lightning, geographical position, time, radio frequency etc

10. Interference

Interference can best be described as the effect of unwanted signals or noise on the reception of a wanted signal
