Ah, yeah, the 24v isn't enough. Gotta use 48v.

I haven't heard of any problems related to the number of SM's with ePMP. You're obviously going to run out of capacity if you have too many, but I imagine if they were all low use connections it'd handle 120 just fine.

It is not recommended to go over 20-30 subs per AP on epmp without loss of performance. I regularly see 450 APs with 70+ subs per AP. With Medusa I have seen over 130. As far as the Medusa not being field proven you may not have field tested it yet, but I know for a fact it has been tested and running on networks for some time now and a viable solution. If you have any more questions feel free to hit me up off list. On 1/5/2017 7:36 AM, David Milholen wrote: <blockquote> The radios on these 2 are entirely different. One is using std based radio and the other completely proprietary. Since framing will be slightly different and so will processing delay. The stds based radio gets close to mimicking the 450 series but thats strictly based on Cambium magic. Capacity and sustained rates per VC is the where you will see a difference. Latency will be very consistent from ap to sub. PMP450i is where its at.

Its not like the FCC gives 450 any more power than epmp, so path loss should be the same. Im looking at this epmp 1000 sector thats running overall about 64-7% efficient with 17 subscribers and wondering what the gain is to move to 450 (exclude medusa, as its not field proven) -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team. -- </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
