I am working on the design of a point-to-point mesh link with two 9124 APs over a distance of 375 meter (enough ground clearance and free line of sight) with the requirement of 800 - 1000Mbit throughput, so roughly a factor 1.7 till 2 of wireless connection speed required.
The 9124D has a 9dBi internal directional antenna and has a 4x4 radio, but calculating on that AP gives me about -65dB on the receiver side (fade margin of 10dB) which doesn't result in a wireless connection of 1700Mbit or higher with 802.11ax on a 80MHz wide channel.
The 9124E with a 13dBi AIR-ANT2513 has a slighty lower TX power but the calculator gives me about -55dB on the receiver side, but with just two streams the throughput also won't be sufficient.
Anyone who can help me with the following questions?
-When using the mesh APs in transparent mode (as a 'wireless ethernet cable'), should we in theory be able to build a port-channel between the switches on both ends using two point-to-point links resulting in a combined throughput > 1Gbit/s? Anyone here who knows if that works or will latency over the wireless medium cause problems with the port-channel?
-Regarding the math for the link budgets: anyone who can educate me from experience (with the 9124 AP?) if my theory matches real-life here?
Regards,
Johan
