In some cases, a Ruckus AP will make the caller's smartphone ask for as much bandwidth as it would need to carry out a call and won't let it connect if it can't get that much. The software can also turn away additional callers if the AP doesn't have enough capacity left to serve them all well. That doesn't necessarily mean those callers are stranded: Ruckus will also provide roaming capability, based on the IEEE 802.11v standard, to send a user to another nearby AP that has the free capacity to serve them.
The software features will only work on Ruckus APs. They will become available over the course of this year.
Ruckus will demonstrate the software features at Mobile World Congress next month in Barcelona, where there is likely to be other news on the spread of Wi-Fi calling. Verizon, AT&T and EE all have said they plan to launch Wi-Fi calling this year.
