![]() ![]() The security aspect in the technology is lacking due to the use of the ad-hoc connection. The main feature of the technology is that it is backward compatible thus, even if one device uses an older protocol, the communication is still possible. Then, there is an ad-hoc connection set up by creating a PAN (personal area network). The initial peer-to-peer connection is initiated by using the traditional Bluetooth protocol. Thus, by utilizing the Wi-Fi radio, the power consumption can be minimized from the classic Bluetooth. The radio is utilized for the initial startup operations, like device discovery, initiating connections, and profile configurations. The 3.0+HS version of the technology uses the Wi-Fi radio for its operation. In the AMP PAL, the AMP MAC is interfaced with the L2CAP and AMP Manager. ![]() The 3.0+HS version enables the use of Generic Alternate MAC/PHY layer the AMP is an addition to this version. ![]() The original architecture lacks this layer and thus had limited features. The layer will increase the throughput of the Bluetooth data transfer. The 3.0+HS version of Bluetooth has an additional 802.11 Protocol Adaptation Layer (PAL), which was absent in the previous versions. Bluetooth 3.0+HS was developed by the Bluetooth SIG and WiMedia Alliance in 2009. ![]()
