Research, Development & Manufacturing

CEM has a R & D lab based in Bangalore, where our engineers research on the next generation communication products. Our arsenal comprises of vast array of products for voice over Ip communication, Video over Ip communication, Broadcast over Ip etc., on which the lab is mainly focused. We do not stop with research but take it further to development, even to the extent of manufacturing our hardware. CEM has a SMT unit in Electronic City (Bangalore) which works hand in hand with the research lab in realizing the visions of our thought. CEM lab team comprises of highly skilled professional from different streams of domains like telecommunication, networking, hardware designing, DSP etc., whose disciplined team efforts help us realize solutions for different telecommunication products. CEM lab has a culture which encourages our engineers to learn different things across their domains, since we believe that a person with a plethora of knowledge can give better solutions than the one who gets stuck in a particular vertical.

Reserach pertaining to Voice:

• CODECS like G.729 A/B , iLBC, Speex, etc.,
• Leveraging wide band codecs like AMR-WB/G.722.2 wide band speech encoding / decoding for more livelier conversation.
• VAD, Echo cancellation etc.,
• VoIP related protocols like SIP, RTP etc.,
• Leveraging open source SIP proxies and media gateways for high performance Voip network elements.

Reserach pertaining to Video includes:

• Working on next generation Codecs like H.264, H.263 etc.,
• Optimizing the video codecs for different DSPs and FPGAs.
• Image processing algorithms for better video resolutions.

Research pertaining to network includes:

• MPLS, DiffServ, RSVP etc.,
• Implementing QoS through the network.

Research pertaining to hassle free service includes:

• In-house robust real time rating and billing systems to charge different services provided.
• Customer friendly sign up system leveraging industrial strength element management system and provisioning systems.
• Presence services to help customer follow their friends and community.

Research pertaining to hardware includes:

• Next generation Analog telephony Adapters (ATAs).
• Optimizing SIP user agents on the ATAs.
• State of art hardware design to make the ATAs more robust.
• Highly optimized embedded media managers and CODECS.
• Best in class media over IP processors.

Research pertaining to hardware:

CEM hardware design team offers Board and FPGA Designs, from a concept to fully functional board, to suit of our product development requirements.

The Hardware Design team at CEM Solutions specializes in ARM, MIPS and DSP based, digital logic designs and various external interfaces.

The team has the ability to handle complex, multi gate designs using state-of-the-art tools.

Our Electronic circuit board design and fabrication using the most affordable and widely used EDA software tools from Cadence Inc.

Appropriate for self-paced study in computer-aided tools for electronic design.

We also use JTAG debugger form MAJIC-Series JTAG probes. This is a Windows GUI debugger provides the best-in-class support for software debug, BSP development, and driver and kernel debugging.

For PCB routing CEM using ALLEGRO DESIGN ENTRY HDL.

This tool is having Advanced schematic capture and part selection capabilities. It combines schematic design entry capabilities with extensive simulation and board layout solutions.

Our researches are not limited these but also includes that unique idea for which any of our engineers shouts Eureka ...
