Linkway S2 Modem Commands

Delivering network-centric connectivity, the LinkWayS2 system integrates voice, video, and data applications, automatically routing information over a mesh, single satellite hop network via unicast or multicast. LinkWayS2 modems are operating on Wideband Global SATCOM (WGS) satellites and can be used over any commercial or military satellite on X-, C-, Ku-, or Ka-band using loop-back, split-beam or cross-strapped transponders.

Expanding on the proven capabilities of the successful LINKWAY 2100 modem, LinkWayS2 modems are more efficient than ever before. Adaptive on-demand bandwidth allocation and bandwidth-efficient coding and modulation engineered into the LinkWayS2 system gives you cost-effective broadband connections between any LinkWay-equipped sites. Features such as turbo coding and 8PSK modulation provide substantial bandwidth savings, reducing your transponder costs compared with other systems.

LinkWayS2 uses a revolutionary new mesh TDMA modem design. Turbo coding provides quasi-error-free connections with minimal carrier power requirements. 8PSK modulationprovides dramatically improved spectral efficiency. Combined with an improved, shorter TDMA preamble, LinkWayS2 is up to 40% more efficient than convolutional-encodedReed-Solomon systems, increasing throughput, reducing station size, and reducing satellite bandwidth requirements.

the LinkWayS2 is a mesh MF-TDMAmodem with completely independent fast-hopping transmitand receive sections. The transmit modulator and receivedemodulator can each tune on a burst-to-burst basis, independentlyand automatically, to any of 64 carriers across an800 MHz frequency range spanning multiple transponders,multiple carrier rates, multiple carrier coding rates, andmultiple carrier modulations. This allows the most efficientallocation of bandwidth on the network carriers, on any availabletimeslot on any available carrier frequency, for the mostflexible and frequency-agile system available.

The IDU features an extended 950-1750 MHz L-band interfaceto the radio frequency transceiver (RFT), for operationacross multiple RF bands limited only by the capability ofRFT. The built-in DVB-S2 receiver uses the same L-bandreceive interface as the TDMA mesh modem for a simple,clean design.

The 900 modem board features dual DVB-S2 demodulators for networks utilizing multiprotocol encapsulation (MPE) traffic, as well as an 8-port Gigabit switch to securely segregate user traffic. The 900 is designed to meet MIL-STD 810G when placed in a properly engineered enclosure. Optimized for integration into both fixed and mobile terminals, the 900 is a powerful board-level solution.

The 900 modem board feature set is also available in a rackmount form factor. The 9350 Modem comes in a 1RU chassis and features an LCD screen, allowing the user to view modem configuration and statistics as well as a zeroize button for added security.

The 950mp Board Satellite Modem is optimized for size, weight, and power (SWaP) with a 30% reduction than its predecessor. Lightweight and power-efficient, the 950mp is designed for integration into highly portable COTM solutions. The 950mp has been industrialized to MIL-STD 810G requirements for extreme operational conditions. This energy efficient modem board builds off of existing transmit keyline capabilities that improve battery performance. The 950mp includes increased memory to support multiple software images for ease of upgrade.

Expanding on the capabilities of the successful LINKWAY 2100 modem, LinkWayS2 modems are more efficient than ever before. The DVB-RCS turbo coding and short preambles provide quasi-error free communications with minimal carrier power requirements and maximum efficiency. The newly added 8PSK modulation feature provides dramatically improved spectral efficiency, while the inclusion of BPSK modulation offers support for ultra-small, sub 1-meter antennas for fixed, at-the-halt or on-the-move communications. LinkWayS2 modems offer a unique extended carrier rate range from 312.5 ksps up to an industry-leading 10 Msps. This broad rate range enables system operators to select the optimal carrier rate for their particular network traffic profile allowing greater flexibility for both high-throughput applications, such as streaming video or large media file transfers, as well as lowlatency applications, such as voice and video teleconference.

Through a software configuration, a LINKWAY 2100 compatible operational mode can be enabled, providing full interoperability with fielded LINKWAY 2100 series networks. Changing configuration from the legacy operational LINKWAY 2100 mode to the more efficient LinkWayS2 mode requires only an over-the-air software download to remote modems and can be done from a centrally managed location.

A DVB-S2 Integrated Receiver/Decoder (IRD) with EN 302 307 compliant coding, provides bandwidth-efficient broadband download capability simultaneous with MF-TDMA operation. Higher throughputs at lower Eb/ No enable broadband connections into reduced size terminals. Additionally LinkWayS2 modems can utilize this capability with any standard EN 302 307 DVB-S2 modulator and IP encapsulator. NETWORK MANAGEMENTLinkWayS2 based terminals are controlled by a full-featured Network Control Center (NCC) management station. The 1 rack-unit NCC server connects to any standard LinkWayS2 modem and manages TDMA network timing, synchronization, terminal acquisition, network configuration, and bandwidth management. The NCC also acts as the Network Management System (NMS) server, a client-server system with a https-based graphical interface. With this approach, a PC-based remote NMS client can securely access the NCC server from anywhere in the world (with appropriate security restrictions). NMS user windows provide network status, network station maps, system configuration, alarm status, connection set-up, accounting, link performance, and diagnostic commands. Local and geographic redundancy ensures reliable network operation and provides automatic network recovery.

LinkWay mesh networks support both ATH and OTM terminals. When combined with GPS, terminal acquisition, synchronization and timing are automatic even when the terminal is in motion. The new LinkWay waveform enables FCC/ITU compliant operation of the LinkWayS2 modems, using ultra-small antennas typically used in OTM platforms.

Viasat Inc. has revealed that their Commercial Broadband Modem (CBM)-400 has now become the first software-defined modem to successfully complete the Army Forces Strategic Command (ARSTRAT) certification process.

By successfully completing the certification process, the Viasat CBM-400 modem is now the only software-defined modem authorized to operate on the Wideband Global Satellite (WGS) communications network, which will significantly enhance air, land and sea performance capabilities while reducing overall satellite communications (SATCOM) costs for U.S. Department of Defense (DoD) customers.
