![]() ![]() If the signal is weak and has to be boosted by a repeater, this can introduce latency. ![]() ![]() Latency can also be introduced by a high percentage of packets that fail to make their destination or too much variation in the time it takes for some packets to travel from one system to another. A large packet will take longer to send round trip than a small one. For example, packets traveling over a T1 line can be expected to experience lower latency than packets traveling over a Cat5 cable. Latency can be affected by the type of media being used to transmit data, voice and video. Latency can be caused by many things, including the following: In any situation where the latency between sensing and responding needs to be extremely low - for example, certain actions in autonomous driving - it makes sense to put the computer that's processing the data as close to the source of the data as possible, a concept known as edge computing. Highly distributed Internet Protocol (IP) networks traverse vast distances, adding transmission time that can derail an application. ![]() One of the major reasons for poor latency is geography. Depending on the application, even a relatively small increase in latency can ruin UX. High network latency can dramatically increase webpage load times, interrupt video and audio streams, and render an application unusable. Network latency can be measured by determining the round-trip time ( RTT) for a packet of data to travel to a destination and back again. Ideally, latency will be as close to zero as possible. In computer networking, latency is an expression of how much time it takes for a data packet to travel from one designated point to another. In telecommunications, low latency is associated with a positive user experience (UX) while high latency is associated with poor UX. ![]()
