Model: EAP211-Bridge KIT  
Hardware Version:
Firmware Version:

I am setting up a Wifi bridge between 8 total buildings - Just want to know if this model or the EAP215 supports 1 master with 7 slaves. Since its wifi are they direct line of site?

3 buildings won't have LOS to the main building hence the WIFI bridge instead of a point to point system.

 

THe network will only be transmitting security camera's.

 

I can't find any literature about adding more slave or if they repeat similar to a mesh.

Hi @JJennings107 

 

Only 4 Sub EAPs can be added at most:

 

And we can't build a string mesh network with EAP Bridge models like below.

EAP bridge1))) ((((EAP bridge 2))) (((EAP bridge 3

Thank you

 

Do they need LOS? or Could i do somethink like this - I normally just build ubuquiti PTP but the cost is going to be to much for the client, so trying an alternate solution

 

Buildings 4,5,6,7 Connected to Bridge 1  -- 13- 4k camera's

Buildings 1,2,3 Connected to Bridge 2 -- 13- 4k camera's

Some questions:

 

Is this is solely for the camera traffic, homing back to the main building?

Are the units each able to order their own internet connection from a local provider?

What is the anticipated bitrate from each camera?

Are cameras on a given building hardwired and uplinked with a wireless unit?

 

My concerns would be around contention for the 5.8G unlicensed band if there are 50+ consumer router/APs blasting.  This is exponentially of concern if the cameras are expecting to connect wirelessly.

 

Building 7 is going to be a problem which will likely need it's own solution back to Main.

Typically i would use a nanobeam setup

- Nano beam on each building going back to the main building

 

- Nanobeam connects to outdoor switch which is then hardwired to each security camera.

 

The main building is a single level vs a 2 story so i would have to create a very high antena on building 7 and 1 to really do line of site.

 

Is this is solely for the camera traffic, homing back to the main building? Yes

Are the units each able to order their own internet connection from a local provider? no would not be cost effective. 50 per month per building.

What is the anticipated bitrate from each camera? 1792 kb/S typically

Are cameras on a given building hardwired and uplinked with a wireless unit? - Camera's will hardwire to an exterior POE switch then to either a PTP or MPTP device- was hoping to try building a wifi bridge system since LOS is going to be difficult.

So none of the units will have any personal wifi APs?  If everyone is going to have 5G wifi hotspots, or there is a common property Wifi, then you really need to channel manage the 5.8G channels being used (and keep the most powerful ones for your long-haul bridges).

 

Here's my initial thinking, basically, for performance reasons, you really want to avoid more than 2 hops, and ideally 2 neighbours (I know it doesn't sound much like a mesh, but it's physics).  You also don't want aggregating nodes (ie 4+ cameras) being RF blind from each other, for instance 3-1 or 4-6 for instance...this leads to contention over the shared channel and causes a lot of retransmits (killing your bandwidth and causing video glitches).  In the below, the sub-bridge on Bldg3 will have the aggregate of 10 cameras which will be fighting for timeslots with the 7 cameras on buildings 4&5, if this doesn't work in practice you can add a new main-bridge on the Main building to feed the bottom end sub-bridge which serves the 6 cameras and 2 sub-bridge nodes for 6&7 (ie extend black arrow back to Main bldg as its own link).  It might also make more sense to pivot Bldg 5 from the Green mesh to the Blue mesh (by way of lowest point of Bld 6 ), but I generally find fewer hops is better in general.

 

Curious to see how this turns out, and I'd strongly suggest a pilot first, say Main,1&2 (orange) to validate.
