3.5.4 Required Bandwidth per Connection

Note that the bandwidth calculation is based on 70 bytes of overhead: RTP (12
bytes), UDP (8 bytes), IP (20 bytes), 802.1Q VLAN Tagging (4 Bytes), MAC (incl.
Preamble, FCS, 26 Bytes).
IMPORTANT: Bandwidth requirements assume Full Duplex operation!
When running Half Duplex, twice the bnadwidth is required.
