For now, voice over LTE is but an idea — one with unrealized potential, as Verizon, AT&T and Metro PCS all still rely on their 3G networks for voice duty. Qualcomm has edged us one step closer to a completely 4G future, though, with the first successful test of a mid-call LTE to WCDMA transfer. Using one of its own chipsets, specifically an MSM8960 Snapdragon S4, the company successfully utilized Single Radio Voice Call Continuity to switch from a VoIP-over-LTE connection to a traditional voice channel over WCDMA. It might seem like a small victory, but it’s one that’s an essential step towards and entirely LTE-dependent network. Check out the complete PR after the break.
