Satellite Network Technologies
Satellite access technology is chosen based on users’ frequency of bandwidth use (continuous or ‘bursty’) and needed application type (voice, streaming video, Internet).
Time Division Multiple Access (TDMA)
TDMA delivers bandwidth efficiency and flexibility to adjust capacity to demand by sharing a pool of bandwidth across multiple sites. TDMA provides Committed Information Rates (CIR) and higher data rates through Burst Information Rates (BIR).
Asymmetrical Single Channel per Carrier (ASCPC)
ASCPC provides dedicated bandwidth from the remote site to the hub and shared bandwidth from the hub to the remote site. This lets customers receive bandwidth efficiency on the outbound channel. ASCPC is optimal for users that send large volumes of data from a remote site to a central location such as corporate headquarters but receive smaller volumes of data at the remote site in periodic intervals.
Single Channel Per Carrier (SCPC)
SCPC provides dedicated bandwidth as space segment is reserved independently for each remote site on both the inbound and outbound links. SCPC is most appropriate for high-capacity requirements and continuous use such as streaming video.
Dynamic Single Channel per Carrier (dSCPC)
Dynamic Single Channel Per Carrier provides true bandwidth-on-demand, offering the low-jitter, low-latency dedicated SCPC connection needed for real-time applications. dSCPC establishes the SCPC carrier for that transmission automatically. dSCPC resizes the carrier based on the increase or decrease in applications being sent over the link, and finally dSCPC technology returns the remote to its home state once the application is complete.
