Satellite access technology is chosen based on users’ frequency of bandwidth use (continuous or ‘bursty’) and needed application type (voice, streaming video, Internet).
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).
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.
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.
Customers' application environments and bandwidth utilization determine
the most appropriate technology for their remote operations.
