Cisco Aironet Mesh Handover

[AlexPM]

Hi there.

There are some questions I would like to clarify:

1 - In case I use Cisco Aironet 1550 or higher in Mesh network how big handover will be? I'm going to use these AP in Mesh network for moving objects with speed up to 40 miles per hour, I will transmit audio from this devices, it would be great if using mesh network I can get seamless handover without dropping a call, I need handover, not more 50ms. Is it possible?

2 - Could you point out where the manual for this is?

3 - If it's not possible to get this handover which devices can I use to get it?

Thanks.

That is a tough question because of a few other variables. How does the wireless device in the mobile vehicle handle roaming with open, PSK, or EAP? Do you have enough coverage that allows for good rssi and snr at all these locations? Is there interference that can cause delays? Is there delay in the backend infrastructure that can cause delay. It’s not much of a wireless system choice, because majority of the enterprise wireless manufacturers support fast roaming, but more of the other variables.

Scott, thanks.

I know it's a tough question, that's why I ask.

Imagine, we have space room 600 sq.feets., with walls made of wood, install 2 AP in 2 corners, there are no other walls or things and just one line that our objects are moving forwards and backwards on with speed 10m/h. We use PSK and have good rssi and snr, in case we don't have a good signal we can add one more AP. What will be with handover?

I just want to understand what the lowest handover we can get if we have ideal conditions?

Thanks.

That can’t be answered without you doing a proof of concept. Adding additional AP’s can and may not help. Will help with coverage but devices might roam more often. So depending on how the devices in the vehicles roam, that tells you what you can and can’t do. You also have to think about if these devices change and then the roaming behavior changes again. There is no document stating the latency because latency is again dependent on the infrastructure and the wireless device, not the wireless system per say.
