Viasat continues to offer the most innovative satellite networking products with the introduction of its most advanced full-mesh MF-TDMA LinkWayS2™ system to date. Battlefield-proven LinkWayS2 modems provide secure at the halt (ATH) and on the move (OTM) satellite communications between users in a single full-mesh MF-TDMA (multi-frequency time division multiple access) network.
Delivering true network-centric connectivity, the LinkWayS2 system seamlessly integrates voice, video, and data applications, automatically routing mission-critical information over a mesh single satellite hop network via unicast or multicast.
Expanding on the capabilities of the successful LINKWAY® 2100 current force modem, LinkWayS2 modems are more efficient than ever before. DVB-RCS turbo coding and minimally short burst preambles provide quasi-error free communications with minimal carrier power requirements and maximum efficiency. Added 8PSK modulation provides dramatically improved spectral efficiency, while the included BPSK modulation and low r = 1/3 error correction coding offers support for ultra-small, sub 1-meter antennas for ATH or OTM communications. LinkWayS2 modems offer an extended carrier rate range, from 312.5 ksps up to an industry-leading 10 Msps. This allows greater flexibility for both highthroughput applications, such as video, or low-throughput applications, such as voice, enabling system operators to select the optimal carrier rate(s) for their particular network traffic profile.
Unique in the industry, the full-mesh LinkWayS2 modem has completely independent fast-hopping transmit and receive paths. The transmit modulator and receive demodulator can each tune to different carriers on a burst-to-burst basis, independently and automatically, across a 1.1 GHz frequency range spanning multiple transponders, carrier rates, carrier coding rates, and carrier modulations. This allows the most efficient allocation of bandwidth, regardless of the burst timeslot or carrier frequency, for the most flexible and frequency-agile system available. LinkWayS2 modems are currently operating on Wideband Global SATCOM (WGS) satellites and can be used over any commercial or military satellite on C, X, Ku, or Ka-band using loop-back, split-beam or cross-strapped transponders.
