6Wireless BasicsWireless products are based on industry standards to provide easy-to-use and compatible high-speed wirelessconnectivity within your home or business. Strictly adhering to IEEE 802.11b, our wireless family of products willallow you to access the data you want, when and where you want it. No longer will you be limited to one locationor forced to run new wiring through your home or office. You will be able to enjoy the freedom that wirelessnetworking delivers.A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radiosignals instead of wires. Wireless LANs are used increasingly in both home and office environments. Innovativeways to utilize WLAN technology are helping people to work and communicate more efficiently. Increasedmobility and the absence of cabling and other fixed infrastructure has proven to be beneficial for many users.Wireless users can use the same network applications they use on an Ethernet LAN. Wireless adapter cardsused on laptop and desktop systems, support the same protocols as Ethernet adapter cards. For most users,there is no noticeable functional difference between a wired Ethernet desktop computer and a wireless computerequipped with a wireless adapter other than the added benefit of the ability to roam within the wireless-cell.Under many circumstances, it may be desirable for mobile network devices to link to a conventional EthernetLAN in order to use servers, printers or an Internet connection supplied through the wired LAN. A WirelessAccess Point (AP) is a device used to provide this link.People use wireless LAN technology for many different purposes.Mobility - Productivity increases when people have access to data in any location within the operating range ofthe WLAN. Ad-hoc management decisions based on real-time information can significantly improve workerefficiency.Low Implementation Costs - WLANs are easy to set up, manage, change and relocate. Networks thatfrequently change, both physically and logically, can benefit from WLANs’ ease of implementation. WLANs canoperate in locations where installation of wiring may be impractical. Furthermore, IEEE standardization mandatesinteroperability of all WLAN devices that conform to the 802.11b set of standards.Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can eliminatethe need to pull cable through walls and ceilings.Wireless Basics (continued)Installation Flexibility - Wireless technology allows the network to go where wires cannot go.Reduced Cost-of-Ownership - While the initial investment required for wireless LAN hardware might be higherthan the cost of wired LAN hardware, overall installation expenses and life-cycle costs will be significantly lower.Long-term cost benefits are greatest in dynamic environments requiring frequent moves, adds, and changes.Scalability - Wireless LAN systems can be configured in a variety of topologies to meet the needs of specificapplications and installations. Configurations are easily changed and range from peer-to-peer networks suitablefor a small number of users to full infrastructure networks of thousands of users that allow roaming over a broadarea.Standards-based TechnologyBased on the IEEE 802.11b standard, the WUS-B12 is also interoperable with existing compatible 2.4 GHzwireless technologies, with data transfer speeds of up to 11 Mbps.Installation ConsiderationsThe WUS-B12 lets you access your network with your laptop computer from virtually anywhere you want. Keepin mind, however, that the number and thickness of walls, ceilings or other objects that the wireless signals mustpass thru may limit range. Typical ranges vary depending on the types of materials and background RF noise inyour home or business. The key to maximizing range is to follow these basic principles:

Wireless Basics (continued)1. Keep the number of walls and ceilings between the Access Point and your receiving device to a minimum –each wall or ceiling can reduce your wireless product’s range from 3-90 feet (1-30 meters.) For somebusinesses or for a large residential home deployment, it may be beneficial to have more than one accesspoint with overlapping coverage.2. Be aware of the direct line between Access Points and computers with wireless adapters - A wall that is 1.5feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle itlooks over 42 feet (14 meters) thick! Try to make sure that the Access Points and Adapters are positioned sothat the signal will travel straight through a wall or ceiling for better reception.3. Building Materials make a difference - A solid metal door or aluminum studs may have a negative effect onrange. Try to position Access Points, and computers with wireless adapters so that the signal passes throughdrywall or open doorways and not other materials.4. Make sure that the antenna is positioned for best reception by using the software signal strength toolsincluded with your product.5. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generateextreme RF noise.For the average residence, range should not be a problem. If you experience low or no signal strength in areasof your home that you wish to access, consider positioning the Access Point in a location directly between thecomputers with wireless adapters that will be connected. Additional Access Points can be connected to providebetter coverage in rooms where the signal does not appear as strongly as desired.Using radio frequency (RF) technology, WLANs (Wireless Local Area Networks) transmit and receive data overthe air, minimizing the need for wired connections. Thus, WLANs combine data connectivity with user mobility,and, through simplified configuration, enable movable LANs.
