- Where Wireless Technology Turns Into Solutions . . .

Bluetooth
Bluetooth wireless technology is aimed at enabling users to make effortless, fast connections between various devices. The sophisticated mode of transmission adopted in the Bluetooth Specification ensures security of data. The radio with Bluetooth wireless technology is built into a small microchip and operates in a globally available 2.4GHz frequency band intended to ensure communication compatibility worldwide. The Specification has two power levels defined: a lower power level that covers the shorter personal proximity range within a room, and a higher power level that can cover a medium range, such as with in a home or office. Software controls and identity coding built into each microchip ensure that only those units preset by their owners can communicate. Bluetooth is a specification for a small-form factor, low-cost radio solution providing links between networks, embedded microcontrollers, machinery, mobile computers, mobile phones, and other portable handheld devices, and connectivity to the Internet.

The Bluetooth Special Interest Group (SIG) was founded in 1998 to manage and promote a new wireless communications standard for connecting devices. The intent was to create a global and open technology standard for a short-range cable-replacement, radio technology. The Bluetooth SIG is led by 3Com, Agere, Ericsson, IBM, Intel, Microsoft, Motorola, Nokia and Toshiba, and more than 10,000 Adopter/Associate member companies.

AT Commands: Just like telephone modems, the Blue Radios serial radio intelligent module powers up into an unconnected state and will respond to inquiry and connection requests. Then, just like controlling a modem, the host or client can issue AT commands which map to various Bluetooth activities. The command set is extensive enough to allow a host to make connections which are authenticated and encrypted or have neither. The Blue Radios serial radio modems can be configured, commanded, and controlled through simple ASCII strings over the Bluetooth RF link or directly through the hardware serial UART.

BlueRadios provides application-specific embedded RF intelligent processor radio module solutions. Our cost effectiveness and versatility of application-specific Bluetooth OEM serial modules will enable you to rapidly integrate wireless technology into your products and services. We provide turnkey wholly-embedded single processor arhitecture serial radio modem data and voice radio module solutions.

BlueRadios Architecture Compared to the Competition

Application-specific modules are embedded Bluetooth modules that take advantage of a unique application software stack, including specific Bluetooth profiles and application to present tailored personalities. They differ from two processor architecture in that they provide a more cost effective and flexible hardware platform for leveraging the versatility inherent in the range of Bluetooth profiles. Physically, an application-specific module is a module with just one chip. One chip contains the microprocessor along with the baseband controller functions. This saves on indirect costs (e.g., real estate) and also direct material costs.

BlueRadios provides wireless business solutions from the sensor to the board room using the following internationally accepted products:

In an independent study Zelos Group LLC predicts that the use of Bluetooth wireless technology will result in cumulative incremental revenues of $12 billion by 2006. The bulk of these revenues will result from use of Bluetooth to link mobile handsets with notebook computers and Personal Digital Assistants (PDAs) to access data services including e-mail. The study examined the expected use of Bluetooth in notebook Personal Computers, PDAs, handsets, headsets, and automobiles for the United States and Western European markets from 2001 through 2006. The research was based on comprehensive interviews with 35 executives at 26 companies including wireless carriers, handset OEMs, providers of automotive electronics, headset vendors, and Bluetooth technology firms.

"More than $11 billion of the forecasted total service revenue will be attributed to users accessing data services through their notebooks or PDAs," said Seamus McAteer, Principal Analyst and Founder of Zelos Group. "E-mail and other forms of messaging like instant messaging and multimedia messaging will be the killer applications, and Bluetooth will enable consumers unprecedented mobile access to these communication tools using their primary computing devices."

The Zelos Group study also predicts the automotive industry as a key medium-term driver for the adoption of Bluetooth wireless technology. Bluetooth wireless technology built into an automobile allows for safer and more convenient cell phone use while operating a motor vehicle. Drivers can wirelessly link their cell phones with the built-in hands-free system and audio system in the automobile. Bluetooth provides the ideal universal car kit and supports compliance with safety regulations mandating hands free use of mobile handsets in the car.
