Hi,
I am looking for some info/experience with recent Voice over WiFi deployment with smartphones.
We have done a couple over VoWiFi deployments with Ascom phones and get good results with that Ascom phones. At a custuomer site we would like to do VoWiFi with Android smartphones. At this site we are using a local controller with AP205 Access Points. We created a dedicated 5 Ghz vlan/ssid for the VoWiFi clients.
So far we did not find any Android phone which does work good. With the most Android phones we tested we get bad roaming experience, so the phone call drops / is silent for a couple of seconds during roaming. With an iPhone we get good results.
So far we did test a Samsung Galaxy S5 Mini, Samsung Galaxy J5, Huawei P8 Lite (no 5Ghz), LG G4 & OnePlus 3. The OnePlus 3 is the best Android phone with roaming, it’s oke. Signal quality / interference is not the problem, clean enviroment. We tried limiting the number of 5Ghz channels so the phone has to scan less channels, this does not improve much.
In the same environment a iPhone 6 roams good.
It could be a solution if we find an Android phone which support 802.11r/802.11k/802.11v and enable this in de WiFi controller. It’s hard to find information about Android phones with that standard and some VoWiFi experience. We did find a couple of Android phone which support that standard but the most phones are not recent Android models.
Even without the 802.11r/802.11k/802.11v enabled in the controller the iPhone just roams good. If we enable these functions it looks like it’s even slightly better. Apple provides clear information about which standard they support.
This thread provided some info but not recent experience.
Can anyone share their thoughts & experience with VoWiFi on smartphones?
