Chapter 3 Wireless Topologies Harmony wireless products look and operate similar to Ethernet products. The only difference is that a radio replaces the wire between various nodes. This means that all of your existing applications that operate over Ethernet will work with Harmony without any special wireless networking software. The Harmony 802.11a network adapters support several network topologies, which are described in this chapter.
Wireless Topologies 24 Infrastructure Many companies have an existing Ethernet or wired LAN infrastructure and want to be able to extend that capability to wireless nodes. This is accomplished by installing one or more Harmony 802.11a Access Points on the Ethernet network. You can also add a Harmony Access Point Controller to the network to simplify Access Point management and take advantage of additional features. See the Harmony Access Point Controller User’s Guide for more information.
Wireless Topologies 25 Roaming Between Multiple APs For larger environments, Harmony 802.11a client devices may roam from one Harmony 802.11a Access Point to another while maintaining the same network connection. The 802.11a Access Points establish coverage areas or cells similar in concept to those of a cellular phone network. The mobile clients will connect to any 802.11a Access Point that is within range. Figure 3 Roaming Each Harmony 802.
Wireless Topologies 26 As the mobile client seamlessly switches from cell to cell, its network connectivity is preserved. The user can move freely between the Harmony 802.11a Access Points on the network. When the roaming client leaves the transmission range of one 802.11a Access Point, the software automatically polls the other 802.11a Access Point(s) in the same Extended Service Set (ESS) to continue the network connection.
Chapter 4 Configuration Parameters This chapter provides information on the 802.11a wireless standard and describes the Harmony 802.11a configuration parameters. The IEEE 802.11a Specification In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices operating in the 2.4 GHz frequency band. This standard includes provisions for three radio technologies: direct sequence spread spectrum, frequency hopping spread spectrum, and infrared.
Configuration Parameters 28 802.11a Software Parameters The following configuration parameters are available for a Harmony 802.11a network adapter. Refer to Chapter 5 for instructions on how to change these configuration settings using the Harmony Utility. Network Mode Network Mode configures a Harmony 802.11a network adapter to operate in either Ad Hoc mode or Infrastructure mode. When set to Ad Hoc, all Harmony 802.
Configuration Parameters 29 Power Saving Mode The Harmony 802.11a network adapters support optional power management to conserve battery life. Power Saving Mode is only available if the adapter is operating in Infrastructure mode. When Power Saving Mode is set to Normal or Maximum, a Harmony 802.11a network adapter enters a “doze” mode where the card becomes inactive and only wakes up periodically to receive control messages from the Access Point.
Configuration Parameters 30 Channel 802.11a devices spread a radio signal over a range of frequencies. The IEEE 802.11a specification allocates the available frequencies in the 5 GHz band into a series of operating Channels that are identified by a Channel number and a center carrier frequency. An 802.11a network adapter configured for Infrastructure mode receives a Channel assignment from its Access Point. You cannot configure the Channel for an adapter operating in Infrastructure mode.
Configuration Parameters 31 For Singapore: An 802.11a network adapter can use one of four Channels: Channel 36 (5.18 GHz), Channel 40 (5.20 GHz), Channel 44 (5.22 GHz), or Channel 48 (5.24 GHz). If you wish to install multiple Ad Hoc networks in the same vicinity, Proxim recommends that you configure each network with a unique Channel to avoid interference between networks. Send Rate The IEEE 802.
Configuration Parameters 32 RTS/CTS The 802.11a standard supports optional RTS/CTS communication based on packet size. By default, RTS/CTS communication is disabled. Without RTS/CTS, a sending radio listens to see if another radio is already using the medium before transmitting a data packet. If the medium is free, the sending radio transmits its packets. However, there is no guarantee that another radio is not transmitting a packet at the same time, causing a collision.
Configuration Parameters 33 WEP Keys An 802.11a device with WEP enabled uses a WEP Key to encrypt and decrypt information. A user must manually enter the network’s WEP Keys on each 802.11a device. If the WEP Keys do not match on two radios, no data communication will take place between these devices. A Harmony 802.11a network adapter can support up to four WEP Keys (all four Keys must have the same Key Size). A Harmony 802.
Configuration Parameters 34 Harmony Security Protocol Guidelines • If you want to use the Harmony Security Protocol on your network, you must enable the protocol on all of your network’s Harmony 802.11a Access Points and Harmony 802.11a clients. • At this time, the Harmony Security Protocol’s client application supports Windows 98 SE, Windows ME, Windows 2000 Professional, and Windows XP. The protocol does not support Windows 2000 Server or Windows NT 4.0.
Configuration Parameters 35 The Harmony Utility does not include configuration settings for 802.1x. To enable 802.1x support and configure 802.1x settings (like EAP authentication type), you need to use a client utility provided by a RADIUS server manufacturer, like Microsoft or Funk Software. Refer to Microsoft’s (http://www.microsoft.com/) and Funk Software’s (http://www.funk.com/) Web sites or the documentation that came with your 802.1x solution for details. Also, see “802.
