Instant Wireless® Series

RTS (Request To Send) - An RS-232 signal sent from the transmitting station to the receiving station requesting permission to transmit.

Server - Any computer whose function in a network is to provide user access to files, printing, communications, and other services.

Software - Instructions for the computer. A series of instructions that performs a particular task is called a "program." The two major categories of software are "system software" and "application software." System software is made up of control programs such as the operating system and database management sys- tem (DBMS). Application software is any program that processes data for the user.

A common misconception is that software is data. It is not. Software tells the hardware how to process the data.

SOHO (Small Office/Home Office) - Market segment of professionals who work at home or in small offices.

Spread Spectrum - Spread Spectrum technology is a wideband radio frequen- cy technique developed by the military for use in reliable, secure, mission-crit- ical communications systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is con- sumed than in the case of narrowband transmission, but the trade off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).

Static IP Address - A permanent IP address that is assigned to a node in an IP or a TCP/IP network.

Subnet Mask - The method used for splitting IP networks into a series of sub- groups, or subnets. The mask is a binary pattern that is matched up with the IP address to turn part of the host ID address field into a field for subnets.

Switch - 1. A data switch connects computing devices to host computers, allowing a large number of devices to share a limited number of ports. 2. A device for making, breaking, or changing the connections in an electrical cir- cuit.

Wireless-G Access Point

TCP (Transmission Control Protocol) - A method (protocol) used along with the Internet Protocol (Internet Protocol) 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 packet) that a message is divided into for efficient routing through the Internet.

TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic com- munication language or protocol of the Internet. It can also be used as a com- munications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is pro- vided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.

Throughput - The amount of data moved successfully from one place to anoth- er in a given time period.

Topology - A network's topology is a logical characterization of how the devices on the network are connected and the distances between them. The most common network devices include hubs, switches, routers, and gateways. Most large networks contain several levels of interconnection, the most impor- tant of which include edge connections, backbone connections, and wide-area connections.

Upgrade - To replace existing software or firmware with a newer version.

Upload - To transmit a file over a network. In a communications session, upload means transmit, download means receive.

UTP - Unshielded twisted pair is the most common kind of copper telephone wiring. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electro- magnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each signal on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable.

WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64- bit, 128-bit, or 256-bit shared key algorithm, as described in the IEEE 802.11 standard.

WAP54G specifications

The D-Link WAP54G is a wireless access point that offers a variety of features aimed at enhancing network connectivity and performance. Designed for small to medium-sized environments, this device is an essential component for creating a reliable wireless network. With its impressive capabilities, the WAP54G easily integrates into existing networks, providing enhanced coverage and flexibility.

One of the main features of the WAP54G is its support for the IEEE 802.11g standard, which allows for data transfer rates of up to 54 Mbps. This standard is backward compatible with 802.11b devices, ensuring that users can maintain connectivity with older hardware. This level of compatibility makes the WAP54G a versatile choice for diverse networking needs.

The device is equipped with advanced security features, including WPA and WPA2 encryption protocols, ensuring that users can protect their network from unauthorized access. These security measures are essential in today’s world, where data breaches are increasingly common. Additionally, the WAP54G supports MAC address filtering, which further restricts access to only authorized devices.

For connectivity, the WAP54G includes multiple Ethernet ports, allowing it to be connected directly to a wired network. This feature enables the access point to bridge the gap between wired and wireless devices, facilitating seamless communication. Moreover, the WAP54G supports Power over Ethernet (PoE), which simplifies installation by allowing it to receive power and data through a single Ethernet cable. This is particularly beneficial in environments where power outlets are limited or difficult to access.

Another noteworthy aspect of the WAP54G is its coverage capabilities. With its adjustable antennas, users can optimize signal distribution throughout a building, overcoming common obstacles such as walls and furniture that can hinder wireless performance. The access point also boasts a user-friendly web-based interface, making it easy to configure and manage settings for both novice and experienced users alike.

In terms of reliability, the D-Link WAP54G features a solid build quality and a compact design, allowing it to fit seamlessly into various environments. The device is also equipped with LED indicators that provide real-time status updates on power, Ethernet connection, and wireless activity, enabling users to monitor their network easily.

Overall, the D-Link WAP54G is a robust wireless access point that combines speed, security, and flexibility, making it an excellent choice for enhancing network performance in both home and office settings.
