Mission-critical VoLTE gear could be available in 2018
LA-RICS plans to use VoLTE for non-mission-critical voice traffic, because there are not enough 700 MHz narrowband channels to support its public-safety users, much less the non-public-safety users that are on the T-Band system, Mallon said.
“Our long-term strategy is that we have to have an LTE system—preferably on the public-safety broadband network—that we can move to and then we can vacate the UHF T-Band only if we have voice communications over the LTE system,” Mallon said during the IWCE session.
“So, from my perspective, the need for voice over LTE and push-to-talk, one-to-many [voice communications] over LTE is absolutely essential, if we’re going to meet the needs going forward—unless the FCC comes up and gives us a whole bunch of spectrum.”
VoLTE will pave the way for
VoLTE will pave the way for the voice portion of Mission Critical Push-to-Talk over LTE that FirstNet will presumably be deploying. It will force carriers to implement end-to-end Quality of Service and shake out any vendor gremlins such as enodeB scheduler bugs that have been lying dormant all this time. It may identify needed improvements that could make their way into standards sooner than if the improvements were identified solely during MC-PTT testing. There is nothing like a jitter-sensitive media stream to identify problems in a cellular network.
