Researchers at the Fraunhofer Institute for Telecommunications' Heinrich Hertz Institute (HHI) are developing new types of data transfer that enable networks to handle huge amounts of data. "We are combining the new LTE mobile communication standard with the [High Efficiency Video Coding (HEVC)] video compression standard, taking the best parts from both technologies," says HHI's Thomas Schierl.
He notes that LTE networks transfer videos and other volumes of data faster, and have shorter time lags, than conventional UMTS standards for data transfer; this is especially critical for videoconferencing, where participants do not want to experience long waits for the responses of their dialogue partner to be transmitted. "LTE allows resources to be distributed to users of mobile services in a very flexible manner," says HHI's Thomas Wirth.
"In addition, new protocols carry information about the application being used, which makes it possible to further optimize transmission."
The researchers are integrating LTE technology with the HEVC video compression standard, which will deliver videos to mobile devices at an even greater speed. "The combination of the two standards will transform user behavior," Schierl predicts.
