What are the network requirements to support Wi-Fi Calling?
You need to be connected to a Wi-Fi network that may be private or public.
It is recommended to use a Wi-Fi Router that supports the 802.11n standard.These routers typically provide better data throughput than older 802.11 b or g routers.
These routers also have the ability to automatically select the Wi-Fi channel to avoid interference from neighboring Wi-Fi signals. Minimum throughput for a quality signal is 1Mbps.
