Term Definition
IR wireless The use of wireless technology in devices or systems that convey data
through infrared (IR) radiation. Infrared is electromagnetic energy at a
wavelength or wavelengths somewhat longer than those of red light.
The shortest-wavelength IR borders visible red in the electromagnetic
radiation spectrum; the longest-wavelength IR borders radio waves.
microwave Electromagnetic energy having a frequency higher than 1 gigahertz
(billions of cycles per second), corresponding to wavelength shorter
than 30 centimeters. Microwave signals propagate in straight lines and
are affected very little by the troposphere. They are not refracted or
reflected by ionized regions in the upper atmosphere. Microwave
beams do not readily diffract around barriers such as hills, mountains,
and large human-made structures.
MIMO An antenna technology for wireless communications in which multiple
antennas are used at both the source (transmitter) and the destination
(receiver). The antennas at each end of the communications circuit are
combined to minimize errors and optimize data speed. MIMO is one of
several forms of smart antenna technology, the others being MISO
(multiple input, single output) and SIMO (single input, multiple output).
MISO An antenna technology for wireless communications in which multiple
antennas are used at the source (transmitter). The antennas are
combined to minimize errors and optimize data speed. The destination
(receiver) has only one antenna. MISO is one of several forms of smart
antenna technology, the others being MIMO (multiple input, multiple
output) and SIMO (single input, multiple output).
near field communication(NFC) A short-range wireless connectivity standard (Ecma-340, ISO/IEC 18092)
that uses magnetic field induction to enable communication between
devices when they're touched together, or brought within a few
centimeters of each other. The standard specifies a way for the devices
to establish a peer-to-peer (P2P) network to exchange data.
optical wireless The combined use of conventional radio-frequency (RF) wireless and
optical fiber for telecommunication. Long-range links are provided by
optical fiber and links from the long-range end-points to end users are
accomplished by RF wireless or laser systems. RF wireless at ultra-high
frequencies (UHF) and microwave frequencies can carry broadband
signals to individual computers at substantial data speeds.
OCSP Client The ArubaOScontroller can act as an OCSP client and issues OCSP
queries to remote OCSP responders located on the intranet or Internet.
OCSP Responder The OCSP client retrieves certificate revocation status from an OCSP
responder. The responder may be the certificate authority (CA) that has
issued the certificate in question or it may be some other designated
entity which provides the service on behalf of the CA.
radio frequency (RF) Portion of electromagnetic spectrum in which electromagnetic waves
are generated by feeding alternating current to an antenna.
structured wireless-aware
network (SWAN)
A technology that incorporates a WLAN into a wired wide-area network
(WAN). SWAN technology can enable an existing wired network to serve
hundreds of users, organizations, corporations, or agencies over a
large geographic area. A SWAN is said to be scalable, secure, and
reliable.
secure copy (SCP)
Secured encrypted command to copy files across an ssh connection,
