Rockwell Collins sets new high mark for data transfer
Rockwell Collins announced the latest record-breaking results of over-the-air trials of Wideband High Frequency (WBHF) technology - a development bringing high-speed data transfer rates over HF channels to a new level.
During the Trident Warrior multi-national exercise in March 2011, Rockwell Collins engineers demonstrated, for the first time, a remarkable data transfer rate of 90 kilobits per second, in an 18 kHz HF bandwidth, over a 1,000-mile HF link between Cedar Rapids, Iowa, and Las Cruces, New Mexico. This rate is more than ten times the typical maximum rate using current technology.
"What our engineers have achieved is nothing less than extraordinary. They've applied their vast communications expertise to break the common perception that the HF band is not capable of supporting data at these transfer rates," said Bruce King, vice president and general manager of Communication Products for Rockwell Collins.
The advent of WBHF ushers in a new era for HF users, enabling them to utilize significant capabilities, previously unavailable via HF, such as streaming video and large file transfers, making HF a "viable augmentation to narrowband satellite communications," explained King.
