WORP Sync version supports fixed data rates and DDRS (Dynamic Data Rate Selection).
In Cambium-PMP  & ePMP mode, configure the Control Slots value based on the configuration of the Cambium
devices. The Control Slots and Maximum Distance configuration values are internally required to calculate the Intra
and Inter Frame Delays, and also to ensure proper synchronization timing between the Proxim and Cambium
systems. 
5.4.3.3 MIMO 
The MIMO Properties tab allows you to configure the Multiple-Input-Multiple-Output (MIMO) parameters to achieve high
throughput and longer range. The MIMO screen appears as shown below.

Description
Frequency Extension
Frequency Extension is applicable only when the Channel Bandwidth is set to 40 MHz.
While choosing 40MHz bandwidth, you can select either 40 PLUS (Upper Extension 
Channel) or 40 MINUS (Lower Extension Channel). 40 PLUS means the center frequency 
calculation is done for 20MHz and add another 20MHz to the top edge of 20MHz. 40 
MINUS means the center frequency calculation is done for 20MHz and add another 
20MHz to the bottom edge of 20MHz.
