Hello to all. We just installed our 1st 4500 8X8 AP a few days ago. Went really smooth using power cable and Fiber for data. We have not deployed any 4525’s or the connectorized radios yet. We have about 20 F300 and 300C units running on it now and all is great! We accually put really great signals on it to keep the retransmit rate very low, like maybe 1%, so thats our plan to put the higher bandwidth best signals on it for now.
My Question: Can anyone estimate if we are running F300 and 300C ONLY cpes on the 8X8 what we should expect our MAX throughput for the AP to be? I know, depends on the MCS, ETC, ETC. But as I stated we are putting really great signals and mcs units only. If anyone has any experience on this I would be interested in hearing what throughput you are getting. If not only 300 units maybe someone that has a mix with both 3 and 4 Cpes running.
Thanks in advance for your help!
It will perform similarly to the 2x2 3000L, except with higher latency and jitter due to ongoing e4k TDD optimization.
Thanks for your take on it. To me, as I understand the 3000L, they did Not have channel filtering. We tried some and had very low throughput as we assumed Cambium would not put out anything that did not have channel filtering, and that was with 30 degree RFE horns to help with noise. We pulled them down, about 16 total, and replaced them with the regular 3000 and the Cambium 4X4 horns and have been very pleased with the thru put. I’ve already seen this 8X8 hit over 150Meg and not be close to flat lining the chart. I would still hope someone will see this thread that has a similar real world set up to chim in. Thanks again for the reply.
We have transitioned from, as an example, e3k 4x4 to e4k 8x8 and have a mix of both AC and AX subscribers, so we do have experience with this scenario and as mentioned I believe the 3000L is the best example to use in terms of what performance to expect and what we’ve seen in the field. You have to remember that the AC clients are limited to 256QAM, 2x2 performance, no MU-MIMO and there’s no beamforming gains… so again, performance is similar to that of a 3000L. If you’re transitioning from a high density e3k 4x4 to a e4k 8x8, you’ll actually take a hit in terms of performance due to the aforementioned limitations. The AC backwards compatibility is really meant to give operators some time to swap out the AC clients for newer AX clients, that can fully take advantage of the 4500’s advanced features.
Very good and excellent response
Hi iamrbf
Which 4500 are you using? The integrated one or the connectorized one?
If you use the connectorized one, what antenna or antennas are you using?
How far away are your subscribers?
What fiber cable are you using? Did you build it yourself or did you buy it made for outdoor use? Could you enlighten me?
