By Ernest Worthman, While Voice over LTE (VoLTE) has been eagerly awaited by carriers, the ability to place voice over IP service on wireless platforms offers operators a path toward a less complex and expensive, more efficient network, with the ability to eventually retire their 3G networks.
However, real-world performance of VoLTE does not stand the quality expectations that users are accustomed to. When it works, it’s fabulous but the quality is all over the map at this juncture. The technology of the devices just isn’t up to prime time quality yet.
It seems that packet losses, which are transparent in data, have a resounding effect on VoLTE. Another glitch in VoLTE seems to be with setup times. They too are all over the map. Reports of 30-second setup times have been documented. And, until small cells are widely deployed so there are very few coverage black holes, VoLTE phones are prone to dropouts and going off-line for seconds to minutes – something that won’t be tolerated by uses.
