AP.book Page 1 Wednesday, October 3, 2001 4:12 PM 1 Chapter 1 Introduction Thank you for choosing Proxim's Harmony 802.11a Access Point, a member of Proxim's Harmony wireless infrastructure family. The Harmony 802.11a Access Point complies with the IEEE 802.11a wireless standard to provide mobile clients with network connectivity at high speed data rates of up to 108 Mbps (in 2XΤΜ mode). The Harmony 802.
AP.book Page 2 Wednesday, October 3, 2001 4:12 PM Introduction 2 The Harmony Family The Harmony 802.11a Access Point is a member of a product family that provides a complete wireless networking solution. • The Harmony Access Point Controller Model 7560 centralizes the management, security, and filtering capabilities of a wireless LAN. The Access Point (AP) Controller communicates with Harmony Access Points over the Ethernet network to provide wireless network access for mobile clients.
AP.book Page 3 Wednesday, October 3, 2001 4:12 PM Introduction 3 Requirements To begin using the Harmony 802.11a Access Point, you must have the following items installed on your local network: • A Harmony AP Controller • A 10Base-T Ethernet or 100Base-TX Fast Ethernet switch or hub • At least one 802.11a adapter Package contents Each Harmony 802.11a Access Point package includes: • One Harmony 802.11a Access Point • One power adapter (12V, 1 Amp) • One Harmony 802.
AP.book Page 4 Wednesday, October 3, 2001 4:12 PM Introduction 4 Access Point Overview Top Panel LEDs The top panel LEDs are (from left to right) the Status Ethernet Wireless and LEDs. Status LED The Status LED gives information about the Access Point.
AP.book Page 5 Wednesday, October 3, 2001 4:12 PM Introduction 5 Wireless LED The Wireless LED blinks green when the Access Point receives data packets over the wireless network. Ethernet LED The Ethernet LED blinks green when the Access Point receives data packets over the Ethernet port. Rear Panel Ethernet Port This port connects the Access Point to your 10/100Base-T Ethernet network using a straight-through Ethernet cable.

AP.book Page 7 Wednesday, October 3, 2001 4:12 PM 7 Chapter 2 Installation The Harmony 802.11a Access Point requires a Harmony Access Point Controller. The AP Controller must be installed on the network before the Harmony Access Point can be installed and configured. See the User Guide that came with your Harmony Access Point Controller for instructions on how to install and configure Access Points on a Harmony network.
AP.book Page 8 Wednesday, October 3, 2001 4:12 PM Installation 8 Installation Determine the best location for the Harmony 802.11a Access Point using the following considerations: • The length of the Ethernet cable that connects the Access Point to the network must not exceed 100 meters. • Place the Access Point indoors, on a flat, sturdy surface as far from the ground as possible, such as on top of a desk or bookcase, keeping clear of metal obstructions and away from direct sunlight.
AP.book Page 9 Wednesday, October 3, 2001 4:12 PM 9 Chapter 3 Configuration Parameters The Harmony 802.11a Access Point must be used in conjunction with a Harmony AP Controller. A Harmony system generally consists of one or more Harmony AP Controllers, one or more Harmony Access Points, and one or more mobile clients that have an 802.11a adapter installed.
AP.book Page 10 Wednesday, October 3, 2001 4:12 PM Configuration Parameters 10 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. Devices that comply with the 802.11 standard operate at a data rate of either 1 or 2 Mbps.
AP.book Page 11 Wednesday, October 3, 2001 4:12 PM Configuration Parameters 11 802.11a Access Point Configuration All Harmony Access Points are configured automatically by the AP Controller or manually using the AP Controller interface. See the User Guide that came with your Harmony AP Controller for information about configuring the Access Point. Once an Access Point is added to a Harmony network, an AP Controller on that network will automatically configure it for operation.
AP.book Page 12 Wednesday, October 3, 2001 4:12 PM Configuration Parameters 12 Auto Configure Default Parameters The AP Controller’s Web interface lists each Access Point underneath the AP Controller with which it is partnered. (An Access Point that is not currently partnered with an AP Controller listed as an Unregistered AP.) The AP Controller will assign default settings to a new Access Point automatically. These settings can be changed using the AP Controller’s Web utility.
AP.book Page 13 Wednesday, October 3, 2001 4:12 PM Configuration Parameters 13 In the United States, the Harmony 802.11a CardBus Card with integral antenna can use three Channels in 2X mode: Channel 42 (5.21 GHz), Channel 50 (5.25 GHz), and Channel 58 (5.29 GHz). See “Radio Frequency interference requirements” on page 7 for important regulatory information concerning Channel selection. Radio Frequency interference requirements The Harmony 802.11a Access Point is restricted to indoor use only. FCC 15.
AP.book Page 14 Wednesday, October 3, 2001 4:12 PM Configuration Parameters 14 Advanced Settings Supported Rates By default, Access Points will support all data rates. The IEEE 802.11a specification supports eight data rates: 54 Mbps, 48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps, 9 Mbps, and 6 Mbps. Harmony’s 2X mode supports eight data rates: 108 Mbps, 96 Mbps, 72 Mbps, 48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, and 12 Mbps. RTS/CTS The 802.
AP.book Page 15 Wednesday, October 3, 2001 4:12 PM Configuration Parameters 15 Roaming Between Access Points A mobile client can roam between Access Points located on different IP networks as long as the Access Points on the remote networks are partnered to an AP Controller on the local network. The client maintains an uninterrupted connection to the network and retains its assigned IP address that is valid on the local subnet.

AP.book Page 17 Wednesday, October 3, 2001 4:12 PM 17 Chapter 4 Troubleshooting The Harmony 802.11a Access Point is designed to be very easy to install and operate. However, if you experience difficulties, use the information in this chapter to help diagnose and solve problems. Refer to the Harmony Access Point Controller User's Guide for additional instructions. If you cannot resolve a problem, contact Proxim Technical Support. See “How to Reach Technical Support” on page 23.
AP.book Page 18 Wednesday, October 3, 2001 4:12 PM Troubleshooting 18 Common Problems and Solutions Table 2: Troubleshooting steps Problem Solution The Harmony 802.11a Access Point does not automatically register with a Harmony AP Controller. Confirm that the Link LED is on. If the LED is not on, check your connection to the local Ethernet network. Try another Ethernet cable. Try repowering the unit. The Access Point will try to contact an AP Controller during boot-up.
AP.book Page 19 Wednesday, October 3, 2001 4:12 PM Troubleshooting 19 Table 2: Troubleshooting steps Problem Solution I want to install a Harmony 802.11a network in my office that has an existing 802.11b network. Will the 802.11a network interfere with the 802.11b network? No. 802.11a and 802.11b devices will not interfere with each other since they operate at different frequencies. 802.11a devices operate in the 5 GHz band, and 802.11b devices operate in the 2.4 GHz band. Is the Harmony 802.
