OUR TECHNOLOGIES


Technology is of value only when put to good use. Through innovative product design and development, Addvalue explores the full potential of ideas and translates them into commercial products.

RF and Antenna

RF competency includes RF analog front-end HPA and LNA design for high-power wireless products such as L-band satellite terminals. Proven capabilities in the design and development patch or omni-directional antenna, antenna integration and matching for a wide variance of fixed and mobile wireless terminals. Design and development of VHF to 5.6GHz products for consumer devices are well within the proven libraries of our RF capabilities.

Baseband Processing

Strong domain knowledge of digital communications technologies and the application of software defined radio. Practical design expertise and development know-how for modern communications at system level and modular level systems. Competent in digital signal processing physical layer FPGA or DSP processor design to perform standard or bespoke solutions for digital signal processing modules such as up/down converter, I/Q odulation/demodulation, error correction coding/decoding, encryption/ decryption and voice coders.


  Embedded Telecommunications Software Development

Diverse development expertise in Embedded Telecommunications Software that includes embedded RTOS (e.g., VxWorks, WinCE.NET, e-Linux, etc.), Board Support Packages and Device Drivers for a wide range of low to high end processors, a wide range of Communication Protocols (e.g., DECT, Bluetooth, UMTS/3GPP, TCP/IP, VoIP, WiFi and other proprietary Communication Protocols etc.), Voice CODECs (e.g., AMBE+2, ADPCM G.726, SB-ADPCM G.722, etc.), a wide range of interface protocols (e.g., USB, I2C, SPI, CAN bus etc.), Digital Signal Processing (e.g., Echo Cancellation), Encryption Techniques and Graphical User Interface.

Industry standard Software Development Processes are used with a strong emphasis on quality, software reusability and robustness. Emphasis is placed on comprehensive design, with rigorous reviews and fully automated host-based testing, leading to a more reliable product in a shorter lifecycle. ..
