Introduction 8
The Harmony Family
The Harmony network adapters are members 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) Con-
troller communicates with Harmony Access Points over the Ethernet network to
provide wireless network access for mobile clients. The AP Controller can support
multiple APs, even if each AP complies with a different wireless standard.
• The Harmony Access Point is a networking bridge that operates at Layer 2 of the
OSI networking model. Working alone or in conjunction with a Harmony AP Con-
troller, the AP forwards packets between its radio and the Ethernet network.
Three types of the Harmony Access Point are available to support the IEEE
802.11a, IEEE 802.11b, or OpenAir wireless standard: the
802.11a Access Point
Models 8569/8570/8571, the 802.11b Access Point Models 8550/8551 and the
OpenAir Access Point Model 7550.
• The optional Harmony Power System Model 7562 provides DC power to Harmony
APs over the unused pins of a twisted pair Ethernet cable.
• The Harmony 802.11a CardBus Card Model 8450 is a wireless LAN adapter that
fits into a 32-bit CardBus slot in a laptop computer and complies with the IEEE
802.11a standard.
• The Harmony PC Card is a wireless LAN adapter that fits into a PCMCIA Type II slot
in a laptop computer. Two models are available to support the IEEE 802.11b
(
8430 Series) or OpenAir (7430 Series) wireless standard.
• The Harmony CompactFlash Card is a wireless LAN adapter that fits into a
CompactFlash slot in a Pocket PC. Two models are available to support the IEEE
802.11b (
Model 8630) or OpenAir (Model 7630) wireless standard.
• The Harmony PCI Card is a wireless LAN adapter that fits into a standard PCI
expansion slot. Two models are available to support the IEEE 802.11a ( Model
8150) or 802.11b (Model 8110) wireless standard.
• The Harmony OpenAir USB Adapter Model 7230 is an OpenAir-compliant wire-
less LAN adapter that connects to a Windows 98/ME/2000 computer’s Universal
Serial Bus (USB) port.
