This Access Point will allow you to network wirelessly better than ever. An access point allows for greater range and mobility within your wireless network while also allowing you to connect the wireless network to a wired environment. The Wireless-N Access Point also offers the convenience of Power over Ethernet (PoE) capability (in addition to regular 12VDC power adaptor), so it can receive data and power over a single Ethernet network cable. This Access Point supports the latest 802.11n draft Specification by IEEE early 2006. It also support 802.11g and 802.11b clients in a mixed environment. This Access Point currently can support an 11n data rate up to 300 Mbps. Besides the higher data rate, 802.11n technology also promises longer coverage by using multiple antennas to transmit and receive data streams in different directions. Users are encouraged to update their firmware through www.linksys.com when 802.11n specification is finalized by IEEE to ensure compatibility with all the wireless-N devices. Networks are useful tools for sharing computer resources. You can access one printer from different computers and access data located on another computer's hard drive. Networks are even used for playing multiplayer video games. So, networks are not only useful in homes and offices, they can also be fun. PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is why the network is called "wired". PCs equipped with wireless client cards or adapters can communicate without cumbersome cables. By sharing the same wireless settings within their transmission radius, they form a wireless network. This is sometimes called a WLAN, or Wireless Local Area Network. The Access Point bridges wireless networks of 802.11n, 802.11g and 802.11b standards and wired networks. Use the instructions in this Guide to help you connect the Access Point, set it up, and configure it to bridge your different networks. These instructions should be all you need to get the most out of the Access Point. access point: a device that allows wireless-equipped computers and other devices to communicate with each other and with devices on a wired network. Also used to expand the range of a wireless network. network: a series of computers or devices connected together. lan (local area network): the computers and networking devices that make up your local network. poe (power over ethernet): a technology enabling an Ethernet network cable to deliver both data and power. ethernet: network protocol defined in IEEE 802.3 standard that specifies how data is placed on and retrieved from a common transmission medium. adapter: a device that adds network functionality to your PC. 802.11n: wireless networking draft standard that specifies a maximum data rate up to 600Mbps (300Mbps supported by this device), an operating frequency of 2.4GHz, and backward compatibility with 802.11b/g devices. 802.11g: a wireless networking standard that specifies a maximum data transfer rate of 54Mbps, an operating frequency of 2.4GHz, and backward compatibility with 802.11b devices. 802.11b: a wireless networking standard that specifies a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.

Chapter 1: Introduction What's in this User Guide? 3 Wireless-N Access Point with Power Over Ethernet Chapter 2: Planning Your Wireless Network Network Topology A wireless network is a group of computers, each equipped with one or more wireless adapters. Computers in a wireless network must be configured to share the same radio channel to talk to each other. Several PCs equipped with wireless cards or adapters can communicate with each other to form an ad-hoc network without the use of an access point. Linksys also provides products to allow wireless adaptors to access wired network through a bridge such as the wireless 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 or wireless network 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 more than doubled since Access Point can transmit signal at higher power to the wireless space. ad-hoc: a group of wireless devices communicating directly with each other (peer-to-peer) without the use of an access point. infrastructure: a wireless network that is bridged to a wired network via an access point. 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 wireless network (SSID) and wireless security settings. This Access Point has 802.11F Inter-Access Point Protocol (IAPP) to complete the roaming process in seconds. If your wireless networks share the same IP subnet, this will not disrupt your data connection while moving around. Before you consider roaming, choose a feasible radio channe ...
