Cell
A single AP and its wireless clients within a wireless infrastructure network containing
multiple APs.
Channel (Frequency)
The center radio frequency that the wireless device uses to transmit.
The RoamAbout PC Card can support up to 13 radio frequency channels as defined in the
IEEE 802.11 Standard. The number of available channels for your PC Card is subject to radio
regulations that apply in your country. In most countries, these radio regulations adhere to
either the FCC or ETSI Standards.
Directional Antenna
An antenna that radiates RF signals in a specific direction. A directional antenna typically has
a higher gain and can cover a greater distance than an omni-directional antenna. A 14 dBi
Yagi directional antenna is available as an option for the RoamAbout AP.
Endpoint Bridge Mode
An AP mode that allows two APs to communicate, effectively connecting two wired LANs
through a wireless link.
Ethernet Adapter
The Ethernet Adapter is used on wired devices (for example, desktop computers and
printers) to make them wireless devices.
ETSI
European Telecommunications Standards Institute (ETSI) regulations.
FCC
Federal Communications Commission (FCC) and Canada (Industry Canada (IC)).
IEEE 802.11 Standard
The Institute of Electrical & Electronics Engineers, Inc. (IEEE) is an organization that
develops standards for electrical and electronic equipment. IEEE 802.xx Standards define the
access technologies for local and metropolitan area networks. IEEE 802.11 compliant
networking products based on the same type of distribution system are interoperable with one
another regardless of the device’s manufacturer.
