Pairing
A Bluetooth pairing occurs when two Bluetooth devices agree to communicate
with each other and establish a connection.
Piconet
A piconet is a Bluetooth PAN that links up to eight devices. Each piconet is
controlled by one master device, and up to seven slave devices at any one time.
Any device may be a member of more than one piconet, changing its
membership as a user moves from one area to another.
RAM
Random Access Memory. Data in RAM can be accessed in random order, and
quickly written and read.
RF
Radio Frequency.
RTC
Real Time Clock.
TDMA
Time division multiple access (TDMA) is digital transmission technology that
allows a number of users to access a single radio-frequency (RF) channel
without interference by allocating unique time slots to each user within each
channel. The TDMA digital transmission scheme multiplexes three signals over
a single channel. The current TDMA standard for cellular divides a single
channel into six time slots, with each signal using two slots, providing a 3 to 1
gain in capacity over advanced mobile-phone service (AMPS). Each caller is
assigned a specific time slot for transmission.
USB
Universal Serial Bus. Type of serial bus that allows peripheral devices (disks,
modems, printers, digitizers, data gloves, etc.) to be easily connected to a
computer. A "plug-and-play" interface, it allows a device to be added without an
adapter card and without rebooting the computer (the latter is known as hot-
plugging). The USB standard, developed by several major computer and
telecommunications companies, supports data-transfer speeds up to 12
megabits per second, multiple data streams, and up to 127 peripherals.
WLAN
A Wireless Local Area Network links devices via a wireless distribution method
(typically spread-spectrum or OFDM radio), and usually provides a connection
through an access point to the wider internet. This gives users the mobility to
move around within a local coverage area and still be connected to the network.
WPAN
A Wireless Personal Area Network is a personal area network - a network for
interconnecting devices centered around an individual person's workspace - in
