Note: Mbps=Msps x FEC x modulation factor (QPSK = 2)
Note: FDMA is required for Standard Tactical Entry Point (STEP) access.
In December 2006, contract was awarded for SWAN-D to General Dynamics for procurement.
Note: The SWAN-D (V1/V2) can only transmit and receive TDMA Ku-band satellite signals.
Time Division Multiple Access
Bandwidth shared between all sites
Each site assigned a time period to transmit as needed
All sites can typically talk to other sites in hub/spoke via the hub
Note: SWAN-D network operation requires one and only one MRT be present and operating in the system.
Frequency Division Multiple Access
Also referred to as point-to-point links
Bandwidth is dedicated to sites
Each site is assigned a pair of frequencies to communicate with the other side (1 transmit and 1 receive)
Note: The SWAN-D (V3) can transmit and receive TDMA and FDMA Ku-band satellite signals.
Note: Utilize 2000 Kbps for SWAN data rates at BCOC.
