The Harmony Family
The Harmony Wirefree Infrastructure Family includes the following products:
❑ The Harmony 7560 Access Point Controller centralizes the management,
security, and filtering capabilities of a wirefree LAN. The Access Point
Controller communicates with Harmony Access Points over the Ethernet
network to provide wirefree network access for mobile clients. The Access
Point Controller can support multiple Access Points, even if each Access Point
follows a different wirefree standard.
❑ The Harmony Access Point is a networking bridge that operates at Layer 2 of
the OSI networking model. Working in conjunction with a Harmony Access
Point Controller, the Access Point forwards packets between its radio and the
Ethernet network. Two models of the Harmony Access Point are available to
support either the OpenAir or IEEE 802.11b wirefree standards: the model
7550 OpenAir Access Point and the model 8550 802.11b Access Point. Note
that only the Harmony Power System operates only with the 802.11b Access
Point.
❑ The Harmony PC Card is a wirefree LAN adapter that fits into a PCMCIA
Type II slot in a laptop computer. Two models of the Harmony PC Cards are
available to support either the OpenAir or IEEE 802.11b wirefree standards.
❑ The optional Harmony Power System provides remote DC power to Har-
mony 802.11b Access Points over the unused pins of a twisted pair Ethernet
cable.
