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). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).
Wi-Fi Direct. Wi-Fi Direct is a Wi-Fi standard for wireless connections [ 1] that allows two devices to establish a direct Wi-Fi connection without an intermediary wireless access point, router, or Internet connection. Wi-Fi Direct is single-hop communication, rather than multi-hop communication like wireless ad hoc networks.
Bluetooth HID is a lightweight wrapper of the human interface device protocol defined for USB. The use of the HID protocol simplifies host implementation (when supported by host operating systems) by re-use of some of the existing support for USB HID in order to support also Bluetooth HID. Keyboard and keypads must be secure.
Bluetooth Low Energy ( Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart[ 1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) [ 2] aimed at novel applications in the healthcare, fitness, beacons, [ 3] security, and home entertainment industries. [ 4]
The Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10. RFCOMM is sometimes called serial port emulation.
This notebook computer is connected to a wireless access point using a PC Card wireless card. An example of a Wi-Fi network. A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building.
lwBT is an open source lightweight Bluetooth protocol stack for embedded systems by blue-machines. It acts as a network interface for the lwIP protocol stack. It supports some Bluetooth protocols and layers, such as the H4 and BCSP UART layers. Supported higher layers include: HCI, L2CAP, SDP, BNEP, RFCOMM and PPP .
Wireless access point. In computer networking, a wireless access point, or more generally just access point ( AP ), is a networking hardware device that allows other Wi-Fi devices to connect to a wired network or wireless network. As a standalone device, the AP may have a wired or wireless connection to a router or router, but, in a wireless ...
