components, their functions and typical deployment.
4.1 System purpose and key features
The Kwikbit M4-2000 system provides for Ethernet bridge connectivity over a point-to-point
wireless link utilizing Sub 6 GHz spectrum. The system operates as an OSI layer 2 (Data Link)
transparent Ethernet switch, connecting the Ethernet ports between a pair of units with a wireless
transparent Ethernet switch, connecting the Ethernet ports between a pair of units with a wireless
data link.
The key features of the system are:

4.2 System components
The M4-2000 consists of a main board and two radio boards. The main board contains an Ethernet
switch device along with the Qualcomm DAN3200 network processor. Each radio employs a MIMO
switch device along with the Qualcomm DAN3200 network processor. Each radio employs a MIMO
antenna system with separate horizontal and vertical polarizations. The dual radio system
operates with radio 1 initially connecting and synchronizing link timing before establishing the
