A
A2CAP : Advanced Audio Distribution Profile
A2DP Advanced Audio Distribution Profile : This profile defines how high quality audio (stereo or mono) can be streamed from one device to another over a Bluetooth connection
AAA Battery : a standard size of dry cell battery commonly used in portable electronic devices
AT commands : the de facto standard language for controlling modems
B
Baseband: describing that part of a radio telecommunication system in which information is processed before modulating on to, or after demodulating off, a radio frequency (RF) carrier wave
Bluetooth low energy, Bluetooth LE, BLE or BTLE: is designed to work side-by-side with and complement Bluetooth. It operates in 2.4 GHz ISM band. Devices using Bluetooth low energy will be smaller and more energy efficient than their classic Bluetooth counterparts
Bluetooth v3.0 +High Speed: In April 2009, Bluetooth v3.0 + High Speed (HS) was launched to support a higher speed, alternative media access controller and physical layer (PHY). Classic Bluetooth retained the control to ensure power consumption is minimized, but a higher speed radio is activated as and when needed to transfer large files quickly. Currently HS supports 802.11 radios, but in future may evolve to support the much higher speed UWB
Bluetooth v4.0: see Bluetooth low energy
Bluetooth: is an open wireless protocol for exchanging data over short distances from fixed and mobile devices
C
Chip: short for a microchip; semiconductor device or integrated circuit
Connectivity: enabling two electronic devices to communicate with each other and transfer data (voice/audio/music/picture/word files) using radio waves
D
Dual mode : one that offers voice and data connectivity to both Wi-Fi and cellular communications within in a single device. Dual-mode devices enable mobile workers to carry fewer devices using converged voice and data applications.
E
ECNR : Echo cancellation and noise reduction
Embedded system : a computer system designed for specific control functions within a larger system often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems contain processing cores that are typically either microcontrollers or digital signal processors. The key characteristic however is being dedicated to handle a particular task.
F
Flash memory: electronic memory where the contents (usually an applications programme) may be programmed prior to use and which retains its contents irrespective of applied power
FTP : File Transfer Profile
G
GAP : Generic Access Profile
GOEP : Generic Object Exchange Profile
H
HCI : Host controller Interface
HFP : Hands Free Profile
HW : Hardware
I
I/O : Input / Output : Refers to the transfer of data to or from an application. Input devices are usually but not always character input devices such as the keyboard, mouse or keyboard. They can also include stream devices like a disk. Output devices include the screen or a printer or anything plugged into a PC's port. Some devices can only send or receive - try sending data to a mouse! If the device can do both input and output (say another PC attached to a serial or parallel cable), it is termed bidirectional.
I2C : Inter Integrated Circuit : I2C is a protocol for communication between various electronic cards. It is a bus (you can connect multiple devices together) common in electronic devices (PC, VCR) and easy enough for widespread use also in robotics.
IP : Intercom Profile
L
L2CAP : Logical Link Control and Adaptation Protocol
LE: Bluetooth low energy
M
Microcontroller: often defined as being a microprocessor together with its memory and a means of allowing input and output
O
OBEX : OBject EXchange
OPP : Object Push Profile
P
PAN : Personal Area Network Profile
PCB : printed circuit board
Point to Point : a communications medium with exactly two endpoints and no data or packet formatting. The host computers at either end had to take full responsibility for formatting the data transmitted between them.
Protocol stack: an implementation of a computer networking protocol suite. The terms are often used interchangeably. Strictly speaking, the suite is the definition of the protocols, and the stack is the software implementation of them
R
Reference Design: A technical blueprint of a system that is intended for others to copy. It contains the essential elements of the system; however, third parties may enhance or modify the design as required.
RF : radio frequency : frequencies of electromagnetic waves between approximately 3 kHz and 300 GHz
ROM : read only memory
S
SCO : Synchronous Connection-Oriented
Semiconductor: a material, typically crystalline, that can be altered to allow electrical current to flow or not flow in a pattern; common semiconductors are silicon, germanium and gallium arsenide and the term is also used to apply to ICs made from these materials
Silicon: a semiconducting material used to make wafers, widely used in the semiconductor industry as the basic material for integrated circuits
Single chip : Refers to one integrated circuit (one chip) rather than two or more. As you trace the evolution of all electronic devices, more circuits are combined onto one chip with every passing year.
Software solution: a solution where instructions and data are read from memory (or memories) and then the instructions interpreted and executed by a microprocessor to modify the data in the intended way
SPI : Serial Peripheral Interface
SPP : Serial Port Profile
Stereo headset: a mobile headset which connects to a mobile phone, PDA, MP3 player or other device using Bluetooth and sits on both ears of the user
SW : Software
SYNC : Synchronisation Profile
U
UART : Universal Asynchronous Receiver/Transmitter : microchip with programming that controls a computer's interface to its attached serial devices. Specifically, it provides the computer with the RS-232C Data Terminal Equipment interface so that it can "talk" to and exchange data with modems and other serial devices.
UWB : Ultra Wideband
V
VDP : Video Distribution Profile
W
WLAN : Wireless Local Area Network : It uses radio waves to ensure the flow of information between the machines (computers or devices) and connected.
