MR76 / ANT-76 - P2P Query

[ITD-Luke]

Hi Community,

I thought I'd put this in to ask, essentially, we're needing advice in terms of the usability of an MR76, ANT-76 for creating a P2P between two locations, the variables are:

1. The main site is 200M away from the existing MX that is connected to a leased line.

2. The new office will have an MS-1308P and an MR36 in.

3. The MR76 & Antenna will connect to an existing MS24P port in the cabinet at the main building, then the MS-138P in the new office.

Will this realistically be the best solution in terms of providing a connection, if the speed will accommodate the 500mb line to the new office? I've done basic checks, but I want to know if anyone has had experience with this and if it'd be a viable solution, or if there's one better to fit these requirements.

Regards,

Luke

From what I understand, you want to use mesh, right?

Viable? Yes, if you have clear LoS and can accept ~200–400 Mbps.
Best solution for 500 Mbps guaranteed? No. For that, use a dedicated P2P wireless bridge or fiber.

Hi Ale,

Essentially, yes. They are sharing a line and 200-400mb would work fine.

If that's the case, that should be all we need.

For the MR76 it lists these as compatible antennas:

https://documentation.meraki.com/Wireless/Product_Information/Overviews_and_Datasheets/MR76_Datashee...

"List of compatible antennas: MA-ANT-20/21/23/25/27 "

Out of those options, the MA-ANT-27 (dual band), MA-ANT-21 (5ghz only) and MA-ANT-23 (2.4 ghz only) seem like the best options to choose from.

Meraki is not the strongest at bridge links.  I would be a bit nervous about this use case.  I would personally use a dedicated bridge solution from another vendor.

If you want to support multiple vlans it might have some challenges.
I do know there is some form of vlan support on the meshing since last year but it does come with some limitations.

You might want to look into the Cisco URWB solution instead for a point to point connection.
There you can use IW9165D's that also support an external antenna type but the internal antenna has a 15 dB gain which is awesome for longer distances.  These can be bought standalone and I'm not 100% sure but if you use them in a point to point manner you either need essentials licensing or none at all.
