Why Doesn't Wi-Fi Work Well With VoIP?
For any VoIP-based solution, TitanX included, a hard-wired internet connection (an Ethernet cable plugged directly into your computer) is recommended. VoIP traffic requires voice data to be sent and received simultaneously to deliver the clearest, most stable audio experience.
Full Duplex vs. Half Duplex
A hard-wired connection is full duplex, meaning it can send and receive (upload and download) data at the same time. This is what keeps a call's audio stable and high quality.
Wi-Fi, on the other hand, is half duplex: the wireless access point can only send or receive data, not both at once. It sends a bit of data, then receives a bit of data, but can't hold a stable, simultaneous connection for VoIP traffic. This is simply a limitation of how Wi-Fi works.
What This Means for Your Calls
VoIP will still work over Wi-Fi, but it can introduce stutters or variability in audio quality during calls, simply due to how Wi-Fi transmits data. To avoid these issues, we recommend being hard-wired to the internet whenever possible.
