Bluetooth® Technology Products One-Stop Development

On communication devices using Bluetooth wireless technology, software, hardware and antenna are closely related in technology, and they determine the product quality.

ACTIVE BRAINS realizes the specifications designed in all plans and projects and can develop Bluetooth units with one-stop actions.

In all sections, cost reduction, product efficiency and product safety can be reviewed and the total management of the projects will be controlled tactically.

Proposals and suggestions will be provided in each development phase of production for interoperability with compatible devices, specifications, prototypes, etc.

Software Development

SIG Standard Profile Design: One of the advantages of when Bluetooth Sig Standard Profile for product communication is to connect various devices in easy steps in accordance with SIG Standard Profiles. ACTIVE BRAINS can realize in a very short period of development, and with extensive embedding experience, every kind of profile in Classic Bluetooth, while providing appropriate software design for the product specifications.

Establishment of Proprietary Profiles: In making products employing wireless communication functions, some restrictions need to be considered for operation when Bluetooth SIG Standard profile is established. ACTIVE BRAINS implements complex specification requests introducing the proprietary profile in the design.

Hardware Design

Circuit/PCB design with respect to high frequency, software and user interface:
Based on our abundant experience of product design, we make circuit designs that comply with the product specifications and its functions. Further, we consider cost, product safety and durability when selecting components and undertaking production.

Design of High Frequency Circuits: When the frequency of signals gets higher in the electrical circuit, the shape and phase of the signals vary and they cause many kinds of problem. Knowledge and know-how of High Frequency, therefore, leads to the designing of circuits for the device, utilizing our experience and its achievements in the improvements in their quality. ACTIVE BRAINS has accumulated extensive expertise in implementing designs and has provided high-grade and quality products for the world market.

Countermeasures for Noise: To design, manufacture and produce electrical devices for the market, it must be ensured that they meet the requirements of EMC (Electromagnetic Compatibility) test. Among them, EMI (Electromagnetic Interference), which has a negative effect on many devices, is specifically regulated in many countries and experience and knowhow are required to obtain its qualification.
Active Brains can possibly reduce noise by optimizing the circuit pattern and the component arrangement. We can design and develop compact-sized wireless modules in accordance with specifications such as VCCI, FCC and EN, and all the major regulations and specifications.

Bluetooth Antenna Design

For antenna designs, various kinds of technical approach are necessary, such as the location of the antenna inside the product, protection from interference from the earthing area, its location and its circuit. One-stop development enables us to design antennas from the very earliest stages.

Impedance Balancing: Communication distance and stability depend mainly on the antenna and this is closely connected with radiating waves efficiently and also with receiving weak signals. One-stop development realizes the best matching for the overall design of antenna and hardware.

Antenna Model: We suggest the most appropriate type and shape of antenna, considering the size and shape of the products used, the environment where those antennas are used, and the distance (range) of communication.

Matching: Using the Bluetooth wireless technology Tester and Network Analyzer, matching is taken to the maximum value of the wave radiation. Performance is evaluated on the basis of radiation features and antenna gain in the anechoic chamber.

Interoperability Tests

ACTIVE BRAINS implements qualified interoperability tests utilizing our extensive experience, from the compilation of manuals accurately based on customers’ requirements to the making of reports after careful consideration.

Manual Compilation: We make accurate manuals based on customers’ requirements. We also suggest the most appropriate test device in accordance with market trends.

Making Tests: When testing just one device, over 1,000 test criteria will be utilized. In assessing operation levels, OK/NG and more stringent and precise checking will be undertaken on demand. Air logs will be obtained and submitted as evidence.

Making Reports: We provide qualified reports incorporating careful consideration, analysis and evaluation. Through software development within our company, we achieve quick solutions to problems in collaboration with SQA (Software Quality Assurance). Our experienced, highly qualified smooth test procedures contribute greatly to reducing the development period and to minimizing the total cost, even after the product is launched in the market.

We have also undertaken interoperability tests on projects under development.
