Can someone from cambium go into the new option to enable Proportional Scheduler on 450M and the default plan speed settings that are present in the configuration options now?

Sorry... I want to understand your question better. Are you asking for further details about what these settings do?
Yes, it's not fully explained anywhere I can find.
To address your specific question see the text below. For a more comprehensive description of the proportional scheduling feature you can check the appropriate sections in the attached documents (search for "proportional scheduler"). these documents are also available on the customer site (https://support.cambiumnetworks.com/files/pmp450/)
If the proportional scheduler is selected, only SMs at 16.1, or later, provide the necessary parameters.
For the older SMs, the AP needs to use default configuration parameters.
The default configuration parameters are as follow:
• SM Weight = 1.0
• User Lock Modulation = Disable
• DL plan
o Allow user to enter a default configuration parameter to be used for all SMs that do
not report a DL plan
o If the user does not enter a configuration parameter, use the lowest DL plan of the
registered SMs
• UL plan
o Allow user to enter a default configuration parameter to be used for all SMs that do
not report an UL plan
o If the user does not enter a configuration parameter, use the lowest UL plan of the
registered SMs

There is a known issue with "occasional stuck sessions on 450m sectors when operating with proportional scheduler" in 16.1. This bug is resolved in 16.1.1. It only impacts 450m and this post referenced the 450m so please upgrade to the latest firmware of 16.1.1 to implement prportional scheduler.
There's also a good training module in our learning portal here . Just look for the module titled "PMP450: Sotware Release 16.1". It has great examples of the behavior with proportional scheduler and different settings for lock modulations, weights, and rate plans.
