The theoretical setup is as follows:
1 AP feeding 2 SMs. The SMs are at the same location. All are Advantage at 5.2 GHz.
Is there a way to “bond” the 2 SMs so that that location will have double the transfer rate? I don’t want to use 2X because 2X is not guaranteed. And if bonding them is possible, what equipment could/should I use?
Also, I have an SM feeding the timing signal to an existing AP on our roof (again, both are Advantage AND in the 5.2 GHz range). If I were to add a second AP (the one listed in the setup above) could I:
1. Split the timing signal from the one SM to both APs. And if this is an option, how would I do that?
OR
2. Put a second SM to provide timing to that second AP. Is that possible? 2 APs receiving the timing signal from 2 SMs all on the same roof?
I just went through that exercise and determined that it was not worth one client using up all the BW on an AP. If they need that much throughput, I suggest that you sell them a private PTP link.
Regarding 1 SM feeding sync to 2 AP’s - not a problem. Take pins 1, 2, 3, 6 from the SM and split it to the two AP’s. We used Scotch Lock telco line splitters with the split safe under the cover of the SM.
I don’t know the limitation on how many AP’s one SM can split to but I don’t think I would go past two. At three I would use a coverage extender http://motorola.canopywireless.com/fp/d … 2ca3423884 or possibly even go to a CMM.

That's exactly what I want to do but using AP & SMs I have in stock. This customer wants a solution for their internal network. They want to connect their main office and remote office. How much effort is required and what did you do?
I assume both sites can see your tower, so it’s a matter of installing the AP, then the SM’s. If the AP is non-advantage then doubling up of SM’s makes sense.
I bet your are reusing your old non-Advantage AP’s? Good use of old equipment, they don’t make anything sitting on a shelf.
One suggestion, look up the cost of a single and a bonded pair private PTP T1 line and then price your service accordingly. WISPs tend to undervalue the services they provide.
We do have a “trial kit” that is non-advantage - 1 AP and 2 SMs. Would like to unload that hardware.
There is very clear LOS between the two buildings with a distance of about 9/10’s of a mile. The plan would be to place the AP on the main building and the SMs on the remote. Would use another SM co-located with AP for timing off our tower which is about 500 feet from the main building.
Monthly pricing, like for bonded T1s does not enter the equation - just the cost of hardware, an installation fee, plus an increase in our current “support” fee. This customer knows that PTP wireless without Internet only involves capital hardware costs.
We are in a unique area where everything is flat with no buildings or trees above 30 feet. Typical elevation is about 8 feet above sea level - as we are on an NJ barrier island. Our tower stands 55 feet above ground level.
So, if we could “bond” two SMs together it would be a win-win for all concerned. Just need to figure out how to do it. Am open to suggestions.
You will want a switch that will allow you to bond two ports. I believe that Cisco 2924 will support this. This allows all traffic to flow across two ports as if they are one without Spanning Tree kicking in. Also, the remote office becomes an extention of the main office.
If you try a load balancing router, some session based traffic may only run across one link defeating the porpose.
