LinkStar Broadband VSAT Modem.
LinkStarS2A now brings you higher efficiency and data rates surpassing many other TDMA systems. LinkStarS2A combines broadband access and a high-speed return channel to satisfy your bandwidth-intensive applications using IP data over any fixed satellite.
Since its introduction, the LinkStarS2A VSAT system has been built on a foundation of open standard DVB technology including a DVB-S or DVB-S2 forward link. The new and innovative LinkStarS2A DVB-S2 technology includes advanced Low Density Parity Check (LDPC) coding for ultra-low Eb/No performance near Shannon’s theoretical limit. That, combined with 8PSK and 16APSK modulation, provides bandwidth reductions of up to 30% below traditional values. Our newly available Adaptive Coding & Modulation (ACM) technology provides rain fade mitigation and reduces the satellite bandwidth requirement for downstream traffic by up to 63%. Dynamic Link Adaptation (DLA) provides rain fade mitigation on the return link while reducing satellite bandwidth by nearly 20%.
The LinkStarS2A system offers satellite link speeds up to 126 Mbps on the downstream and up to 4.2 Mbps on the upstream channels to the hub. With this high upstream channel capacity, remote sites can be server locations, content providers, multimedia sources, video teleconferencing participants, and corporate headquarters.

Automatic Rain Fade Compensation
Adaptive Coding & Modulation (ACM) for the downstream reduces satellite bandwidth requirements by up to 63%. (Optional)
Dynamic Link Adaptation (DLA) reduces upstream satellite bandwidth requirements almost 20%. (Optional)
Dynamic Uplink Power Control automatically boosts signal level during fading conditions, ensuring your network will stay connected.
Acceleration and Compression improves link efficiency and enhances user experience
HTTP Acceleration & Bandwidth Reduction with AcceleNet boosts the speed of your customers’ web surfing experience while reducing your operating costs for satellite bandwidth. (Optional)
TCP Acceleration boosts the speed of your TCP traffic enhancing your end users’ experience.
IP Header Compression significantly reduces the bandwidth required for VoIP traffic by eliminating extraneous and redundant protocol information.
Quality of Serivce (QoS) based on DiffServ offers six queues at the scheduler level on each remote terminal. You get a finer prioritization of user traffic based on profiles defined using the IP QoS feature.
Multiple Inbound Access Schemes to Support a Wide Range of Applications give you the ability to meet or exceed your customers’ expectations.
Bandwidth on Demand (BoD) dynamically increases bandwidth as it is needed, for as long as it is needed. Ideal for multi-user Intranet and Internet applications as well as large file transfers.
Committed Information Rate (CIR) provides nearinstantaneous accessibility of all available bandwidth. Ideal for guaranteed Quality of Service (QoS) applications. Combined with the LinkStarS2A system’s applicationtriggered CIR feature, this is the right choice for VoIP and video conferencing services.
Application-Triggered BoD/CIR allows dynamic assignment of BoD/CIR resources, maximizing resources and matching customer-specific application requirements. (Optional)
CIR Reallocation offers CIR when the user needs it. Once the needs are satisfied bandwidth becomes available to the entire network. This allows operators to fully utilize bandwidth resources.
Slotted ALOHA grants immediate network access to lowbandwidth applications. This powerful feature minimizes latency and is particularly suited for transactional applications such as lotteries, point-of-sale (POS) and automated teller machines (ATMs).
DHCP Relay and VLAN Tagging enable service providers to offer VPN services to multiple customers through this optional feature. The LinkStarS2A system enables end-to-end VLAN separation of customer traffic, reuse of private addresses, and automatic IP address assignment to devices at remote sites.
Frequency Hopping allows your network to be more efficient through load balancing across return channels.
Powerful Network Management System (NMS)
Our Web-Based NMS gives you configuration control and network management using GUI and a standard browser. The Network Control Center (NCC) provides additional management through traffic statistics, call detail records and an SNMP interface. Other features include:
* Virtual Network Operator (VNO) (optional)
* Virtual Service Provider (VSP) (optional)
* User Groups (logically group remote terminals)
* Online Context-Sensitive Help
FLEXIBLE, SCALABLE ARCHITECTURE
With each Regional NCC (RNCC) managing up to 8,000 sites and a single NCC controlling up to 10 RNCCs, you can grow your network to a total of up to 80,000 nodes.
Compact C-SERIES HUBS are available for smaller, scalable, cost-effective networks allowing for system growth.
MULTI-SATELLITE/MULTI-TRANSPONDER You can choose to operate in C, Ku, and Ka band, utilizing a unique region for each requirement. REDUNDANCY Ensure your critical communications through both local and/or geographic redundancy for the hub.
DVB-Based Architecture enables service providers and satellite operators worldwide to build open-standard networks for IP data, Internet access, video streaming, telemedicine, VoIP and distance learning. For operators who require standardization on the return channel, the LinkStarS2A network offers an optional DVB-RCS compliant version with a simple, cost effective over-the-air software download.
MULTIMEDIA, BROADBAND CONNECTIONS provide up to 126 Mbps on the downstream and up to 4.2 Mbps per upstream carrier.
Encryption is available for the downstream traffic, up stream traffic, and network control channel.
Network Locking controls migration of terminals across networks. (Optional)
IPSec is transparently delivered by the LinkStarS2A system. NEW Data Encryption using AES-128 is now available. (Optional)
Control Plane Security encrypts network management messages for highly secure communications. (Optional)
ADVANCED IP ROUTING CAPABILITY Unicast and Multicast, RIP, IGMP, UDP, TCP are all supported by the LinkStarS2A system.
INPUT POWER OPTIONS include a choice of AC and DC power. Intelligent power conservation is ideal for solar applications.
MARITIME/MOBILE OPERATION allows installation on moving platforms such as ships and vehicles.
HYBRID STAR/MESH NETWORKS provide flexibility for a multitude of applications in one integrated network. Sharing a common DVB-S2 outlink, the LinkStarS2A system is interoperable with ViaSat’s LinkWayS2 mesh VSAT system.
