LR

Local area network (LAN) - a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server.

N

Network Operations Center - A place from which a network is supervised, monitored, and maintained. Also referred to as the Network Management Center (NMC).

Network Address Translation (NAT)- a method of connecting multiple computers to the Internet (or any other IP network) using one IP address.

P

Performance enhancing proxy (PEP) - modules that provide TCP acceleration. PEP is used to improve the performance of the Internet protocols on network paths where native performance suffers due to characteristics of a link or subnetwork on the path.

Private IP addressing - A computer on the Internet is identified by its IP address. In order to avoid address conflicts, IP addresses are publicly registered with the Network Information Centre (NIC). Computers on private TCP/IP LANs however do not need public addresses, since they do not need to be accessed by the public. For this reason, the NIC has reserved certain addresses that will never be registered publicly. These are known as private IP addresses.

Router - a device or, in some cases, software in a computer, that determines the next network point to which a packet should be forwarded toward its destination.

S

Signal quality factor (SQF) - an integer value from 0-99 that indicates the strength of the received satellite signal relative to noise.

Subnet mask - a 32-bit value that is used to distinguish the network ID from the host ID in an arbitrary IP address. Each host on a network requires a subnet mask.

T

TCP/IP internet protocol suite - the basic communication language or protocol of the Internet.

TCP Acceleration - see PEP.

Transmission control protocol (TCP) - a set of rules (protocol) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet.

Turbo Page - software that prefetches objects from Web sites you visit to speed up surfing.

DW6000 specifications

The Hughes DW6000 is a high-performance satellite modem designed primarily for broadband Internet access, particularly in remote and rural areas where traditional wired options aren’t feasible. This equipment is prominent within Hughes Network Systems' lineup of satellite communication technologies and offers a robust solution for both residential and commercial applications.

One of the standout features of the Hughes DW6000 is its compatibility with the HughesNet satellite broadband service. It supports two-way satellite Internet connectivity, allowing users to send and receive data simultaneously, which enhances Internet speed and efficiency. The modem operates on the Ka-band, which is known for providing higher bandwidth and faster data transmission rates compared to traditional Ku-band systems.

The DW6000 is equipped with advanced technologies such as Adaptive Coding and Modulation (ACM), which dynamically adjusts data transmission rates based on network conditions. This feature ensures optimal performance and availability of service, even under less-than-ideal weather conditions or during peak usage times. Additionally, it includes built-in Quality of Service (QoS) capabilities, which prioritize network traffic to maintain steady, reliable performance for applications like video streaming and VoIP.

With a user-friendly design, the Hughes DW6000 offers straightforward installation and setup processes, making it accessible for users who may not have technical expertise. Its compact size also allows for easy placement in various environments.

Moreover, the modem supports various interface options, including Ethernet for connecting multiple devices, and USB connections for individual setups. This versatility makes it a fit for both home networks and small office environments.

The DW6000 also has security features in place, including encryption options to safeguard data transmission. This is particularly important in today's digital landscape, where data privacy and security are vital considerations.

In summary, the Hughes DW6000 satellite modem stands out for its robust features, including support for high-speed Internet access, dynamic transmission adjustments through ACM, and user-friendly installation. Its versatility, combined with essential security measures, makes it a solid choice for anyone looking to establish reliable connectivity in hard-to-reach locations. Whether for home use or business applications, the DW6000 delivers the performance needed to keep users connected in an increasingly digital world.
