radio |
Bluetooth
radio is a transceiver which transmits and receives modulated
electrical signals from peer Bluetooth devices. The radio for
compatability reasons should have some defined transmitter and
receiver characteristics. More

| Baseband |
Baseband
is the physical layer of the Bluetooth which manages physical
channels and links apart from other services like error correction,
data whitening, hop selection and Bluetooth security.

| ACL |
ACL is
Asynchronous Connection-Less physical link for transmitting data
over the physical channels. ACL link provides a packet switched
connection between the master and all the active slaves.

| SCO |
SCO is
Synchronous Connection-Oriented physical link for voice-like
information. It is a symmetric, point-to-point link between the
master and a specific slave. It behaves like a circuit-switched
connection. More

| Link
Manager |
Link
Manager essentially handles link set-up, security and control. It
provides services like authentication, encryption control, power
control and provides QoS capabilities. It also manages devices in
different modes (park, hold, sniff and active).

| L2CAP |
L2CAP
is the Logical Link Control and Adaptation Layer protocol. It
resides in the data link layer and provides connection-less and
connection-oriented data services to upper layer protocols with
protocol multiplexing capability, segmentation and reassembly
operation and group abstractions. L2CAP permits higher level
protocols and applications to transmit and receive L2CAP data
packets up to 64 Kb in length. More

| SDP |
SDP is
Service Discovery Protocol for applications to discover which
services are available and to determine the characteristics of those
available services. |
| RFCOMM |
RFCOMM
is a simple transport protocol, with additional provisions for
emulating the 9 circuits of RS-232 (EIATIA-232-E) serial ports over
L2CAP protocol. It supports up to 60 simultaneous connections
between two Bluetooth devices. |

TCP/IP |
TCP
(Transmission Control Protocol) provides a reliable connection
between devices at the transport layer with IP (Internet Protocol)
in the network layer. IP provides protocol multiplexing and
connections based on IP addresses.

JINI |
Jini
technology provides simple mechanisms which enable devices to plug
together to form an impromptu community--a community put together
without any planning, installation, or human intervention. Each
device provides services that other devices in the community may
use. These devices provide their own interfaces, which ensures
reliability and compatibility. JINI works on higher layers while
Bluetooth works at much lower layers. There are interesting
opportunities to put JINI on top of Bluetooth Protocol.

WAP |
WAP is
Wireless Access Protocol is a standard for
providing Internet communications and advanced telephony services on
digital mobile phones, pagers,
personal digital assistants and other
wireless terminals. More
