Can a Subscriber Module 450i 900 be programmed as a single PTP / Master, Slave access point?
It cannot. There is a different 900Mhz ptp sku that is the same hardware though. I’m not aware of a license key “upgrade” to enable this on the standard SM, but maybe Cambium can help.
Yes, technically all 450i/450b/MicroPoP hardware can act as a PTP, or PMP AP or PMP SM. It is just a matter of purchasing the License Key for it.
I’m a software engineer so not familiar with the procedure to buy License Keys, but I’d suggest contact your distributor or Regional Technical Manager or open a Customer Support ticket. If that fails then can contact @CambiumMatt.
Actually, we do not have a license key part number for this. As @Charlie says, please work through your channel partner or RSM, and we may be able to help.
