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 54 Mbps (up to 108 Mbps in 2XTM mode*). The Harmony 802.
Introduction 7 The Harmony Family The Harmony 802.11a Access Point is 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.
Introduction 8 System 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 (with firmware version 2.0 or greater installed) • A 10Base-T Ethernet or 100Base-TX Fast Ethernet switch or hub • At least one 802.11a adapter The Product Package Each Harmony 802.11a Access Point package includes: • One Harmony 802.
Introduction 9 Harmony 802.11a Access Point Models There are three models of the Harmony 802.11a Access Point available. All three units are identical except for the differences noted below. Model 8569/8570 • These two models are identical (they have different part numbers for marketing purposes) • Includes two integral antennas that provide antenna diversity; these antennas cannot be removed from the unit • Provides up to eight independent Channels in 802.
Introduction 10 Access Point Overview Figure 1: Harmony 802.11a Access Point Model 8569/8570 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.
Introduction 11 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 Figure 2: Harmony 802.11a Access Point Model 8569/8570 Rear Panel Ethernet Port This port connects the Access Point to your 10/100Base-T Ethernet network using a straight-through Ethernet cable.
Introduction 12 Power Port The Harmony 802.11a Access Point has a power port on its back panel. The voltage range for the Access Point’s power connector is 10-26 VDC. Proxim recommends that you connect only the Class 2 power supply (12V, 1 Amp) provided with the product to the power port. In addition, the Access Point can accept power from a Harmony Power System, which is an alternative power source to the supplied Class 2 power supply. The Harmony Power System is sold separately.
Chapter 2 Installation The Harmony 802.11a Access Point requires a Harmony Access Point (AP) Controller. The AP Controller must be installed on the network before the Access Point can be installed and configured. See the User’s Guide that came with your Harmony AP Controller for instructions on how to install and configure Access Points. Note: The AP Controller must have firmware version 2.0 or greater installed to support the Harmony 802.11a Access Point.
Installation 14 Radio Frequency Interference Requirements The Harmony 802.11a Access Point Models 8569 and 8570 operate in the frequency range of 5.15 to 5.35 GHz; they are restricted to indoor use due to their operation in the 5.15 to 5.25 GHz frequency range. FCC 15.407(e) requires that these devices be used indoors in the frequency range of 5.15 to 5.25 GHz to reduce the potential for harmful interference to co-channel Mobile Satellite systems.
Installation 15 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.
Installation 16 4. The Link LED on the rear panel will light to indicate that the Access Point has a network connection. The LED is lit green if connected to a 100Base-TX network and lit amber if connected to a 10Base-T network. 5. By default, the Harmony 802.11a Access Point will attempt to find an AP Controller to partner with.
Installation 17 Mounting Instructions The Harmony 802.11a Access Point ships with a wall mounting kit so that the unit can be mounted to a wall or ceiling. The wall mounting kit contains the following parts: • One AP Mounting Disk • Two Plastic Wall Mount Anchors • Two #6x0.

Insert the second screw into the remaining mounting hole and screw it into the remaining wall anchor or directly into the wall. 6. Tighten the two screws to secure the mounting disk to the wall. 7.
Chapter 3 Configuration The Harmony 802.11a Access Point must be used in conjunction with a Harmony AP Controller. A Harmony System that supports 802.11a 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. Each Access Point acts as an intermediary between its mobile clients and the AP Controller, converting radio signals into Ethernet packets and vice versa.
Configuration 21 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. In 1999, the IEEE modified the 802.
Configuration 22 802.11a Access Point Configuration All Harmony Access Points are configured automatically by the AP Controller or manually using the AP Controller interface. See the User’s Guide that came with your Harmony AP Controller for information about configuring the Access Point.
Configuration 23 Auto Configure Default Parameters The Harmony System’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 is listed as an Unregistered AP.) The AP Controller will assign default settings to a new Access Point automatically. These settings can be changed within the System’s Web interface. See your AP Controller User’s Guide for more information The 802.
Configuration 24 Operating Mode The Operating Mode determines how the Access Point communicates with its partnered AP Controller. There are three options: Tunneled, Managed and Automatic. When set to Tunneled, the Access Point does not communicate with the Ethernet network directly; all traffic is sent to or received from the AP Controller using an encapsulation technique known as IP Tunneling. In Tunneled mode, an Access Point receives its configuration settings from the AP Controller.
Configuration 25 Channel The Harmony System automatically assigns a Channel to each new Harmony 802.11a Access Point added to the network. You can also manually configure each Access Point’s Channel after it has been added to the Harmony System. Note: The Channel for Access Points sold in Europe is dynamically assigned by the Harmony System and cannot be manually configured.
Configuration 26 SSID By default, the Harmony System configures new Access Points with the default Service Set ID (“proxim”). The SSID is a string of up to 32 ASCII characters that must match on all communicating 802.11a devices within the same network. All Harmony Access Points and Harmony clients must use the same SSID to allow roaming between Access Points. Group Membership Each Access Point can belong to one Access Point Group for management and configuration purposes.
Configuration 27 Security Settings The Harmony 802.11a Access Point offers three security settings: No Security, Use WEP for Encryption and Authentication, and the Harmony Security Protocol. WEP Encryption and Authentication The IEEE 802.11a standard specifies an optional encryption feature, known as Wired Equivalent Privacy or WEP, that is designed to provide a wireless LAN with a security level equal to what is found on a wired Ethernet network.
Configuration 28 Harmony Security Protocol The Harmony Security Protocol automates encryption management, assigning a unique and dynamic WEP Key to each user.
Configuration 29 Advanced Settings Supported 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. Note: Access Points sold in Europe and Japan do not support 2X mode. As a mobile client moves away from an 802.
Configuration 30 Fragmentation The Harmony 802.11a Access Point supports an optional feature called Fragmentation. In harsh radio environments, 802.11a devices may have difficulty transmitting large packets that exceed a certain size. However, when Fragmentation is enabled, the 802.11a Access Point can break up large packets into a number of smaller packets (called “fragments”) that can be successfully transmitted to another 802.11a device. The receiving 802.
Configuration 31 Roaming Between Access Points If there are multiple Harmony 802.11a Access Points on the network, then a mobile client may seamlessly roam from one Access Point to another. Each Access Point creates its own wireless cell or coverage area. This is also known as a Basic Service Set (BSS). A mobile device can communicate with a particular Access Point if it is within the Access Point’s coverage area.
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. Also, refer to the Harmony Access Point Controller User’s Guide for additional troubleshooting suggestions. If you cannot resolve a problem, contact Proxim Technical Support. See “Technical Support and Training” on page 41.
Troubleshooting 33 Range Every environment is unique with different obstacles, barriers, materials, etc., and, therefore, it is difficult to determine the exact range that will be achieved without testing. Radio signals may reflect off of some obstacles or be absorbed by others depending on their construction. 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.
Troubleshooting 34 Common Problems and Solutions Symptom/Question Possible Solution/Answer 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. Also, try another Ethernet cable. • Try repowering the unit. The Access Point will try to contact an AP Controller during boot-up.
Troubleshooting 35 Symptom/Question Possible Solution/Answer My office has an existing 802.11b network. Is the Harmony 802.11a Access Point compatible? No. 802.11a devices are not compatible with 802.11b devices. 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.
