Cardiologists follow surgery in real-time while in a conference hall
The projection in the conference hall shows live open-heart surgery. The audience watches the operation attentively on a screen, and they listen to the surgeon’s comments. Viewers in the hall also converse directly with the physician. The occasion was the international CSI conference at the Congress Center of the Frankfurt Trade Fair from June 22 to June 25, 2016. The organizer had asked HDwireless to install bi-directional transmission paths (radio links) between operating theater and the congress center so that cardiologists from all over the world would be able to watch several surgeries live and of dependable high quality.
For the transmission in full HD resolution of HD-SDI in 1080/50i over a distance of approximately 10 km the best answer proved to be radio waves in a frequency range of 2 to 3 GHz. In agreement with the Hessian Federal Network Agency HDwireless assumed responsibility for the frequency planning. To increase the transmission safety frequency filters were installed, which guaranteed flawless live transmission of the surgery demonstration for the academic faculty members. For faultless real-time communication between the Congress Center and the operating room HDwireless applied its own point-to-point transmission technology. Patrick Nussbaum comments: “For wireless transmission we embedded the sound into the transmission signal, only to separate it after decoding. We used our HDwireless-fiberglass network on both sides of the radio links. Our client took over complete and latency free signals.”
This way the cardiologists with their high analytic requirements were able to follow various surgeries live and synchronized in highest uncompressed quality.
