Wireless carrier Orange UK has noted today the launch of "high definition calls", an upgrade to call quality.
The updated voice service will use Wideband Adaptive Multi-Rate (WB-AMR) for speech transmission which allocates 5x more bandwidth for a call than normal 3G voice, while using the same or only slightly more data. Orange says that two users calling each other with HD calling should expect the clarity to be as if both "were actually in the same room."
It is still unclear however if any current handsets can be updated to support WB-AMR, but Orange will have new phones available with the standard supported in 2010 alongside a wider rollout.
