7 The Wireless Technology Standard The Wireless Access Point utilizes the 802.11b and the 802.11g standards. The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54 Mbps (108Mbps in Super G mode) within the 2.4GHz band, utilizing OFDM technology. This means that in most environments, within the specified range of this device, you will be able to transfer large files quickly or even watch a movie in MPEG format you’re your network without noticeable delays. This technology works by transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the amount of cross talk (interference) in signal transmissions. The AP will automatically sense the best possible connection speed to ensure the greatest speed and range possible. 802.11g offers the most advanced network security features available today, including: WPA, WPA2, TKIP, AES and Pre-Shared Key mode. UPlanning Your Wireless Network Network Topology A wireless network is a group of computers, each equipped with one wireless adapter. Computers in a wireless network must be configured to share the same radio channel. Several PCs equipped with wireless cards or adapters can communicate with one another to form an ad-hoc network. The wireless adapters also provide users access to a wired network when using an access point or wireless router. An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an infrastructure network can talk to any computer in a wired network infrastructure via the access point or wireless router. An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and may double the effective wireless transmission range for two wireless adapter PCs. Since an access point is able to forward data within a network, the effective transmission range in an infrastructure network may be doubled.

8 Roaming Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they both share the same channel and SSID. Before enabling you consider roaming, choose a feasible radio channel and optimum access point position. Proper access point positioning combined with a clear radio signal will greatly enhance performance. Network Layout The AP Access Point has been designed for use with 802.11g and 802.11b products. With 802.11g products communicating with the 802.11b standard, products using these standards can communicate with each other. The Access point is compatible with 802.11g and 802.11b adapters, such at the PC Cards for your laptop computers, PCI Card for your desktop PC, and USB Adapters for when you want to enjoy USB connectivity. These wireless products can also communicate with an 802.11g or 802.11b wireless Print Server. When you wish to connect your wired network with your wireless network, the Access Point’s network port can be used to connect to any of switches or routers. Installation Considerations The AP lets you access your network, using a wireless connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines:  Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.  Keep the number of walls and ceilings between the AP and other network devices to a minimum - each wall or ceiling can reduce your AP’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized.  Be aware of the direct line between network devices. A wall that is 1.5 feet thick(.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick!

9 Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception.  Building materials can impede the wireless signal - a solid metal door or aluminum studs may have a negative effect on range. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials. Applications The wireless LAN products are easy to install and highly efficient. The following list describes some of the many applications made possible through the power and flexibility of wireless LANs:  Difficult-to-wire environments There are many situations where wires cannot be laid easily. Historic buildings, older buildings, open areas and across busy streets make the installation of LANs either impossible or very expensive.  Temporary workgroups Consider situations in parks, athletic arenas, exhibition centers, disaster-recovery, temporary offices and construction sites where one wants a temporary WLAN established and removed.  The ability to access real-time information Doctors/nurses, point-of-sale employees, and warehouse workers can access real-time information while dealing with patients, serving customers and processing information.  Frequently changed environments Show rooms, meeting rooms, retail stores, and manufacturing sites where frequently rearrange the workplace.  Small Office and Home Office (SOHO) networks SOHO users need a cost-effective, easy and quick installation of a small network.  Wireless extensions to Ethernet networks Network managers in dynamic environments can minimize the overhead caused by moves, extensions to networks, and other changes with wireless LANs.  Wired LAN backup Network managers implement wireless LANs to provide backup for mission-critical applications running on wired networks.

CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) - A method of data transfer that is used to prevent data collisions. CTS (Clear To Send) - A signal sent by a wireless device, signifying that it is ready to receive data. Database - A collection of data that is organized so that its contents can easily be accessed, managed, and updated. DHCP (Dynamic Host Configuration Protocol) - A networking protocol that allows administrators to assign temporary IP addresses to network computers by "leasing" an IP address to a user for a limited amount of time, instead of assigning permanent IP addresses. Download - To receive a file transmitted over a network. DSSS (Direct-Sequence Spread-Spectrum) - Frequency transmission with a redundant bit pattern resulting in a lower probability of information being lost in transit. DTIM (Delivery Traffic Indication Message) - A message included in data packets that can increase wireless efficiency. Encryption - Encoding data transmitted in a network. Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Firmware - The programming code that runs a networking device. Fragmentation -Breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet. Gateway - A device that interconnects networks with different, incompatible communications

47 protocols. Hardware - The physical aspect of computers, telecommunications, and other information technology devices. IEEE (The Institute of Electrical and Electronics Engineers) - An independent institute that develops networking standards. Infrastructure - A wireless network that is bridged to a wired network via an access point. IP (Internet Protocol) - A protocol used to send data over a network. IP Address - The address used to identify a computer or device on a network. ISM band - Radio bandwidth utilized in wireless transmissions. ISP (Internet Service Provider) - A company that provides access to the Internet. LAN - The computers and networking products that make up your local network. MAC (Media Access Control) Address - The unique address that a manufacturer assigns to each networking device. Network - A series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users. Node - A network junction or connection point, typically a computer or work station. Packet - A unit of data sent over a network. Passphrase - Used much like a password, a passphrase simplifies the WEP encryption process by automatically generating the WEP encryption keys for Linksys products. Port - The connection point on a computer or networking device used for plugging in cables or adapters. Roaming - The ability to take a wireless device from one access point's range to another without losing the connection. Router - A networking device that connects multiple networks together.

Server - Any computer whose function in a network is to provide user access to files, printing, communications, and other services. SNMP (Simple Network Management Protocol) - A widely used network monitoring and control protocol. Software - Instructions for the computer. A series of instructions that performs a particular task is called a "program". SOHO (Small Office/Home Office) - Market segment of professionals who work at home or in small offices. Spread Spectrum - Wideband radio frequency technique used for more reliable and secure data transmission. SSID (Service Set IDentifier) - Your wireless network's name. Static IP Address - A fixed address assigned to a computer or device that is connected to a network.

48 Subnet Mask - An address code that determines the size of the network. Switch - 1. A data switch that 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 circuit. TCP (Transmission Control Protocol) - A network protocol for transmitting data that requires acknowledgement from the recipient of data sent.
