Wireless Basics D-Link AirPro wireless products are based on industry standards to provide easy-touse and compatible high-speed wireless connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard, the D-Link AirPro wireless family of products will allow you to securely access the data you want, when and where you want it. You will be able to enjoy the freedom that wireless networking delivers. A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. Wireless LANs are used increasingly in both home and office environments, and public areas such as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate Wireless Basics more efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven to be beneficial for many users. Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop and desktop systems support the same protocols as Ethernet adapter cards. Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Router 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 of the WLAN. Management decisions based on real-time information can significantly improve worker efficiency. Low Implementation Costs – WLANs (Wireless Local Area Networks) are easy to set up, manage, change and relocate. Networks that frequently change, both physically and logically, can benefit from WLANs ease of implementation. WLANs can operate in locations where installation of wiring may be impractical. Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can eliminate the need to pull cable through walls and ceilings. Network Expansion - Wireless technology allows the network to go where wires cannot go. Scalability – Wireless Local Area Networks (WLANs) can be configured in a variety of topologies to meet the needs of specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to larger infrastructure networks to accommodate hundreds or thousands of users, depending on the number of wireless devices deployed. Wireless Basics The DI-764 is compatible with other D-Link AirPro 802.11a products, which include: ♦ 5GHz Wireless Cardbus Adapters used with laptop computers (DWL-A650) ♦ 5GHz Wireless PCI Adapters used with desktop computers (DWL-A520) The DI-764 is also compatible with the D-Link AirPlus 802.11b wireless family, which includes: ♦ Enhanced 2.4GHz Wireless Cardbus Adapters used with laptop computers (DWL-650+) ♦ Enhanced 2.4GHz Wireless PCI cards used with desktop computers (DWL-520+) Standards-Based Technology The versatile DI-764 Multimode Wireless Broadband Router integrates both 802.11a and 802.11b standards into a single unit. The IEEE 802.11a standard designates that devices may operate at an optimal data rate of 54 Mbps (72 Mbps in proprietary Turbo mode.) 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 over 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 crosstalk (interference) in signal transmissions. D-Link AirPro 802.11a products will automatically sense the best possible connection speed to ensure the greatest speed and range possible. Based on the IEEE 802.11b standard, the DI-764 is also interoperable with existing compatible 2.4GHz wireless technology with data transfer speeds of up to 22Mbps (with the D-Link AirPlus family of wireless devices,) as well as standard 802.11b technology ( the D-Link Air family of wireless devices), with speeds of up to 11Mbps. Wireless Basics Installation Considerations The D-Link AirPro DI-764 lets you access your network, using a wireless connection, from virtually anywhere. 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: 1. Keep the number of walls and ceilings between the DI-764 and your receiving device (e.g., the DWL-A650 or the DWL-650+) to a minimum each wall or ceiling can reduce your D-Link AirPro Wireless product’s range from 3-90 feet (1-30 meters.) Position your receiving devices so that the number of walls or ceilings is minimized. 2. Be aware of the direct line between routers and computers. 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! Try to make sure that devices are positioned so that 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 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. 4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise. Getting Started Right out of the box, with its default settings, the DI-764 will connect with other D-Link Air, AirPlus or AirPro products. With a single IP Address from your Broadband Internet Service provider you can share the Internet with all the computers on your local network, without sacrificing speed or security, using D-Link Air networking products. IP ADDRESS Note: If you are using a DHCP-capable router in your network setup, such as the DI-764, you will not need to assign a static IP Address. If you need to assign IP Addresses to the computers on the network, please remember that the IP Address for each computer must be in the same IP Address range as all the computers in the network, and the Subnet mask must be exactly the same for all the computers in the network. For example: If the first computer is assigned an IP Address of 192.168.0.2 with a Subnet Mask of 255.255.255.0, then the second computer can be assigned an IP Address of 192.168.0.3 with a Subnet Mask of 255.255.255.0, etc. IMPORTANT: If computers or other devices are assigned the same IP Address, one or more of the devices may not be visible on the network. An Infrastructure wireless network contains an Access Point. The Infrastructure Network example, shown here, contains the following D-Link network devices: A wireless Broadband Router - D-Link AirPro DI-764 A laptop computer with a wireless adapter - D-Link AirPro DWL-A650 or AirPlus DWL-650+ A desktop computer with a wireless adapter - D-Link AirPro DWL-A520 or AirPlus DWL-520+ A Cable modem - D-Link DCM-200 10 Getting Started Please remember that D-Link AirPro wireless devices are pre-configured to connect together, right out of the box, with the default settings.
