Trango Systems TrangoLINK GigaPlus - Wireless Link Capacity

Trango Systems, Inc. GigaPlus User Manual Rev 3.1 37
Wireless Link Capacity
The table below shows the capacity of the system for each non-ACM speed setting. The
capacities for the ACM settings will be approximately 1-2% lower due to the additional
overhead of the ACM.
All capacities shown are in Mbps full duplex, meaning that the aggregate bidirectional
capacity is twice the number shown.
The capacities shown are also layer 2 using 1518 byte packets for IPV4, rounded to the
nearest Mbps. Layer 1 numbers will be higher, especially for small packets:
