Ethernet header compression
Example shows that in 60MHz channel and 1024QAM modulation over 1Gbps throughput
can be achieved with Ethernet header compression of frame size of 64 bytes in 1+0
configuration, where link capacity is 465 Mbps:

Table shows maximum improvement achieved, when compressing IP header, QinQ VLANs
headers, MAC addresses and Ethernet L1 overhead. Ethernet throughput for each frame size
can be calculated for any link capacity by using calculated gain from the table. For example,
at 465 Mbps radio capacity with Ethernet compression gain of 56.52% of 64 byte size
packets can achieve 1069 Mbps Ethernet throughput, i.e. 465 Mbps / (1 – 56.52%) = 1069
Mbps.
