Hi,

I am thinking of experimenting with the new MR500 from open-mesh to create a corporate network. This network would need to be very dense as it is in a concrete structure with many small rooms. It could have each Access point\router hardwired to the LAN if needed.

My question is roaming. I would use SSID #2 as a bridge to the LAN. IF I roam from one hardwired AP to another, will the TCP connection of the client connected to SSID #2 be reset?

Will this product work like Meraki or Aerohive in a situation where roaming is a critical function? Will it hand off a Voice Over IP device to the next Access point without dropping calls?

Thanks,
mercyh

If you use SSID #2 then you can get the same IP between devices, however, as for being able to roam, I'm not sure.

I have received a reply from Open-mesh on their new MR500. Using the NG firmware they say it will work, however it is beta at this time.

On the public mesh ssid, changing gateways changes the NAT router so roaming is broken.

IF you use SSID 2 and bridge it to your LAN, they say it will work. I think I am going to purchase about 5 of them and start testing.....

if so ...you could deploy simple Access Points only w/out the need of a mesh network Smile

As Antonio says, why bother with the mesh - Have a look at the Ubiquiti Unifi system , for ease of use or simple access points.

I have done this at another location (and should have used unifi) with Cisco AP's and have had fierce problems with interference between access points. We have tried tuning every way possible but we have areas where two or three AP's have about equal strength signal on the same channel and we cannot get coverage. We also must use channels 1, 6, 11 to try and mitigate this problem and have completely saturated the 2.4ghz band.

Meraki and Aerohive claim to overcome this problem by using mesh even if all AP's are hardwired to keep bandwidth high (eliminate repeater bandwidth loss).

I know that what I am doing is a lot different than most here, but if your product and technology can be adapted to do it well, the cost is about 25% of a controller based network.....

I know where you are coming from, but it simply doesn't scale well in such a situation - you will still have problems with interference. All the hardware that that Robin works on though allows you to drop the output power, to help with the signal problems.

Robin is great, but we had to use a different solution when dealing with installs like you mention - in the end , we went down the MikroTik route, which worked out more than using Robin, but not by a huge amount - and certainly a lot less than a controller based WiFI Network system.
