Demand Assigned Multiple Access (DAMA): the same satellite transponder of problems 1 and 2 is configured in a multi-frequency TDMA (MF-TDMA) fashion, with four independent 30 MHz channels, each employing their own independent TDMA data streams. (a) Note the slight reduction in total aggregate bandwidth due to channelization - how has the potential aggregate user data rate changed? (b) If each user is assigned a fixed allocation of 100 kbps (user data rate) as a base rate, what total user data rate is available to be assigned on a DAMA basis? (c) DAMA links generally require a four-hop handshake (two hop to the transmitter and two hop to the intended receiver) to establish the request for additional timeslots and to receive the specific timeslot assignments. How long does this take? (d) Look up the Carrier Sense Multiple Access - Collision Avoidance (CSMA/CA) protocol used with terrestrial WiFi links - does the DAMA satellite link in (c) support CSMA/CA? If not, what needs to be adjusted to maintain the communications link?
