Bluetooth beacons use Bluetooth Low Energy proximity sensing to transmit a universally unique identifier [1] picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, [2] track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification .
The way a device uses Bluetooth depends on its profile capabilities. The profiles provide standards that manufacturers follow to allow devices to use Bluetooth in the intended manner. For the Bluetooth Low Energy stack, according to Bluetooth 4.0 a special set of profiles applies.
iBeacon is based on Bluetooth low energy proximity sensing by transmitting a universally unique identifier [4] picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, [5] track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification .
Smart phone ad hoc networks use the existing hardware (primarily Bluetooth and Wi-Fi) in commercially available smartphones to create peer-to-peer networks without relying on cellular carrier networks, wireless access points, or traditional network infrastructure. Wi-Fi SPANs use the mechanism behind Wi-Fi ad-hoc mode, which allows phones to ...
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).
Piconet. A piconet is an ad hoc network that links a wireless user group of devices using Bluetooth technology protocols. A piconet consists of two or more devices occupying the same physical channel (synchronized to a common clock and hopping sequence). It allows one master device to interconnect with up to seven active slave devices.
The iPhone 4 is a smartphone that was designed, developed, and marketed by Apple Inc. It is the fourth generation of the iPhone lineup, succeeding the iPhone 3GS and preceding the iPhone 4s. Following a number of notable leaks, the iPhone 4 was first unveiled on June 7, 2010, at Apple's Worldwide Developers Conference in San Francisco, [9] and ...
Used to allow devices to discover what services each other support, and what parameters to use to connect to them. For example, when connecting a mobile phone to a Bluetooth headset, SDP will be used to determine which Bluetooth profiles are supported by the headset ( headset profile, hands free profile, advanced audio distribution profile, etc ...
