I have a PtP link made by 2 C5c equipment, with a 30 dBi dish,
Point A is in the hill
Point B is in the city
The distance is about 5.3 mi(8.5 Km)
When I put the A equipment as AP, the PHY PER grafh show 0-0.5% and the transfer between both sites are excellent, the MAC Tx/Rx (Mbps) is: 144 / 36, but I need the opossite in Tx/Rx, I need more upload than download in hill side, so I put the B point in AP mode, same channel size, same channel. When I put that configuration, things go very bad, the PHY PER grafh show 20-50% almost constantly, the MAC Tx/Rx (Mbps) is: 16 / 20 or less, and transfers between both sites are terribly bad, when I return to the original config: Point A(hill) as AP and point B(city) as suscriber, all return to excellent connection conditions.
Why the connection goes bad when the point B acts as AP? I need to allow transfer almost 100 Mbps to the point A, the issue is that my upload link are in the maxium permitted.
