O Canada: Rogers is first of the “Big Three” to offer Voice-over-LTE
VoLTE allows carriers to handle voice calls over the 4G high-speed network without having to rely on traditional circuit-switched protocols. For the customer, the result is reduced time to set-up a call, and HD voice quality.
For the carriers, it allows much more efficient use and management of spectrum, effectively increasing potential capacity. Rogers says it will be able to rollout more robust features with video calls and video sharing as VoLTE gains wider acceptance across the network.
While we are sure that Telus and Bell are not far behind, Rogers can claim some extra swagger since it is the only kid on the Canadian block offering VoLTE. Saskatchewan based SaskTel was the first in Canada to roll out VoLTE.
Voice calling usage patterns may be trending downward, but the HD quality voice is pretty remarkable. Have you experienced HD voice and VoLTE?
