SHANHAI-5272 Bluetooth Gateway

INTRODUCTION
Mobiles can support In ternet function but slowly, xDSL\Cable modem can access the Internet but fixed. Only bluetooth wireless technology takes a ll the

advantages to realize high speed and moveable connection to the Internet . Bluetooth Gateway is the key device to bridge wireless and wired netwo rk fast

and freely. With Bluetooth Gateway, you can enjoy the Internet anytime anywhere.

SHANHAI-5272 Bluetooth Gateway is the first bluetooth gateway products under its own intellectual property in China. The gateway link bluetooth terminal to

existing wired network, such as PSTN,DDN,ISDN,Internet,ADSL to realize bluetooth station to access the Internet and telecontrol bluetooth devices or other

equipments in other network.

Key Features

1.Bluetooth Gateway is compliant with bluetooth standards, adopts Time-Division Multiple Access technology, supports asynchronism transmission and point to

point or point to multipoint bluetooth data communication. Bluetooth terminal and its piconet can communicate with traditional wired network by TCP/IP

protocol.

2. It's small. Dimension:150mm*100mm*50mm

3.analyze bluetooth protocol, TCP/IP protocol and IEEE802.11 standard, interpret bluetooth address to IP address, support part of software function on

protocol conversion in multi-operating system.

4. Protocol stack implement technology from physical layer to transport layer. Adopt universal ethernet interface as physical layer interface of LAN.

Realize protocol conversion between bluetooth and TCP/IP by SCM.

5. Piconet adopts HUB top structure, supports SCO/ACL wireless link and host & multi-slave mode. Based on sub protocol, Bluetooth Gateway resolved route

problem by software dynamic route path arithmetic to realize communication among different bluetooth piconet.

6.Supports bluetooth data and voice communication, encapsulated most of HCI instructions. Voice communication function widen its use area.

* Bluetooth Gateway comprised of cells as following

* Bluetooth Equipment Interface Cell
* RF Cell
* Ethernet Interface Cell
* Protocol Implement Cell
* Protocol Conversion Cell
* Management Interface Cell

System Configuration Structure

Each bluetooth equipment which connected to Bluetooth Gateway must bind to a TCP port of Bluetooth Gateway. Thus, we can uniquely identify the bluetooth

terminal in the LAN or the Internet by IP and TCP port. When bluetooth equipments are communicating with the host, Bluetooth Gateway takes charge of

conversion work between bluetooth protocol and TCP/IP, enable data exchange between bluetooth equipments and computer network transparently.
