How to Use LinkWay S2 Modem Commands for Satellite Communications

The LinkWay S2 modem is a tactical network-centric satellite communication system that provides secure and efficient connectivity for voice, video and data applications. The modem supports various network topologies, such as full-mesh, star or hybrid, and can operate on different frequency bands and transponders. The modem also features adaptive on-demand bandwidth allocation, bandwidth-efficient coding and modulation, embedded AES encryption-based TRANSEC, and backwards compatibility with the LINKWAY 2100 modem[^1^] [^2^].

To use the LinkWay S2 modem commands, you need to have a network control center (NCC) management station that connects to any standard LinkWay S2 modem and manages the TDMA network timing, configuration, monitoring and control[^2^]. The NCC provides a graphical user interface (GUI) that allows you to access various functions and settings of the modem. You can also use a command line interface (CLI) to enter commands directly into the modem via a serial port or a telnet session[^2^].

Some of the common LinkWay S2 modem commands are:

show status: This command displays the current status of the modem, such as the network ID, node ID, carrier ID, frequency, modulation, coding rate, burst rate, transmit power, receive signal level, etc.

show config: This command displays the current configuration of the modem, such as the network parameters, node parameters, carrier parameters, encryption parameters, etc.

set config: This command allows you to modify the configuration of the modem, such as the network parameters, node parameters, carrier parameters, encryption parameters, etc. You need to enter the parameter name and value after the command. For example, set config nodeid 10 sets the node ID to 10.

save config: This command saves the current configuration of the modem to a file on the NCC or on the modem itself.

load config: This command loads a configuration file from the NCC or from the modem itself to the modem.

reset: This command resets the modem to its default state.

reboot: This command reboots the modem.

zeroize: This command erases all encryption keys and data from the modem.

LinkWay S2 Modem Applications

The LinkWay S2 modem is designed to meet the diverse and demanding needs of the tactical warfighters and other users who require reliable and secure satellite communications. The modem can support various applications, such as:

Command and Control (C2): The modem enables real-time exchange of voice, video and data among different command levels and units, enhancing situational awareness and decision making.

Intelligence, Surveillance and Reconnaissance (ISR): The modem supports high-throughput transmission of sensor data, such as imagery, video and signals intelligence, from airborne, ground or maritime platforms to analysts and operators.

Logistics and Support: The modem facilitates efficient coordination and delivery of supplies, equipment and personnel to remote locations, as well as tracking and monitoring of assets and inventory.

Disaster Relief and Humanitarian Assistance: The modem provides rapid and resilient connectivity for emergency response teams, relief agencies and affected populations, enabling coordination, information sharing and delivery of essential services.

The LinkWay S2 modem can be integrated with various types of terminals, such as fixed or transportable antennas, vehicle-mounted systems, manpacks or handheld devices[^1^] [^3^]. The modem can also interoperate with other SATCOM systems, such as DVB-S2 modems or IP encapsulators[^2^]. This allows the users to leverage existing infrastructure and equipment, as well as access multiple networks and services.

LinkWay S2 Modem Benefits

The LinkWay S2 modem offers several benefits over other SATCOM systems, such as:

Cost-effectiveness: The modem eliminates the need for a large and costly VSAT central hub, reducing the capital and operational expenses. The modem also optimizes the bandwidth utilization through adaptive on-demand allocation and efficient coding and modulation, lowering the transponder costs.

Performance: The modem delivers high-quality voice, video and data communications with minimal latency, jitter and packet loss. The modem also provides robust transmission security (TRANSEC) with embedded AES encryption, concealment of channel activity, over-the-air authentication, rekeying and zeroization.

Flexibility: The modem supports any network topology (full-mesh, star or hybrid), any frequency band (X-, C-, Ku-, or Ka-band) and any transponder type (loop-back, split-beam or cross-strapped). The modem also allows independent fast-hopping transmit and receive paths across a wide frequency range.

Scalability: The modem can accommodate any number of nodes in a single network, as well as multiple networks in a single satellite beam. The modem also enables mixed-node networks using ultra-small antennas and on-the-move terminals coexisting with larger fixed location terminals.

Backwards compatibility: The modem is compatible with the LINKWAY 2100 modem, allowing seamless migration and integration of legacy systems.

The LinkWay S2 modem is the battlefield standard for C4I satellite communications, providing secure and efficient connectivity for a variety of applications.
