In the past many outside broadcasting applications have relied on using satellite uplinks in order to broadcast live audio and video back to the studio. While this has its advantages such as the ability to set up virtually anywhere covered by the respective geostationary satellite, satellite uplinking is very expensive and the round trip latency is in the range of 240 to 280 milliseconds.[1] Modern applications such as hardware and software IP codecs have allowed the use of public 3G/4G networks to broadcast video and audio. The latency of 3G is around 100–500 ms, while 4G is less than 100 ms.[2]
