This profile allows devices such as car phones with built-in GSM transceivers to connect to a SIM card in a Bluetooth enabled phone, thus the car phone itself does not require a separate SIM card and the car external antenna can be used.
A Bluetooth earbud, an earphone and microphone that communicates with a cellphone using the Bluetooth protocol. Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs).
Google has partnered with Bluetooth SoC designers including Qualcomm, Airoha Technology, and BES Technic to add Fast Pair support to their SDKs. [3] In May 2019, Qualcomm announced their Smart Headset Reference Design, Qualcomm QCC5100, QCC3024 and QCC3034 SoC series with support for Fast Pair and Google Assistant . [ 5 ]
The SIM card provides the module with a unique identification number, which is used to identify the device on the network. The GSM module then communicates with the network using a set of protocols, which allows it to send and receive data. The GSM network is a digital cellular network that uses a set of protocols to enable communication ...
Every SIM card contains a secret key, called the Ki, which is used to provide authentication and encryption services. This is useful to prevent theft of service, and also to prevent "over the air" snooping of a user's activity. The network does this by utilising the Authentication Center and is accomplished without transmitting the key directly.
Hands-free phone kit fitted to a Saab 9-5.. Handsfree is an adjective describing equipment that can be used without the use of hands (for example via voice commands) or, in a wider sense, equipment which needs only limited use of hands, or for which the controls are positioned so that the hand can occupy themselves with another task (such as driving) without needing to hunt far afield for the ...
Hands-free computing is important because it is useful to both able and disabled users. Speech recognition systems can be trained to recognize specific commands and upon confirmation of correctness instructions can be given to systems without the use of hands. This may be useful while driving or to an inspector or engineer in a factory environment.
In 2011, the Bluetooth SIG announced the Bluetooth Smart logo so as to clarify compatibility between the new low energy devices and other Bluetooth devices. [6] Bluetooth Smart Ready indicates a dual-mode device compatible with both classic and low energy peripherals. [7] Bluetooth Smart indicates a low-energy–only device which requires ...
