name: BT
full_form: Bluetooth
context: mean that all the devices shown in the figure are accessing simultaneously using single (U)SIM. Figure 1: (U)SIM Security Re-use by Peripheral Devices Using Local Interfaces (USB/BT, etc.) Figure 1 shows some of the different types of (U)SIM security re-use related usage models that are possible. The local interfaces depicted are either BT based or USB based or PC card interface or also could be based on any other wired or wireless interconnect technology. Some of the scenarios illustrated are: - PDA with WLAN capability re-using the SIM inside a GSM Terminal over a BT interface; - Notebook PC with WLAN capability re-using the SIM inside a GSM Terminal over a BT interface; - Notebook PC with WLAN capability re-using the USIM inside a UMTS Terminal over a BT interface; - Notebook PC with WLAN capability re-using the SIM from a plug-in GPRS PC card module; - Notebook PC with WLAN capability re-using a USIM from a UMTS terminal over a USB interface; - GSM-GPRS-WLAN multi-mode terminal
description: Bluetooth (BT) is a short-range wireless technology that enables devices to communicate with each other. It's used in various applications, including secure communication for (U)SIM cards by peripheral devices as mentioned in 3GPP TS 33.817.
explanation: Bluetooth is classified as a Wireless Communication Technology because its primary function is to facilitate wireless data transfer between devices over short distances.
