Job Details
Description
Innovation at its Best: Join our Forward-Thinking Company
At CableLabs we wake up every day to invent the future. CableLabs is a global, award-winning innovation and R&D lab dedicated to keeping people connected by building and orchestrating emergent technology and igniting co-innovation today for the broadband of tomorrow.
The Wired R&D Radio Frequency (RF) Technologist Intern position resides in the Wired Technologiesdepartment at CableLabs. This department is focused on the innovation and development of new Wired accesses technologies for our Cable Operator members. The Wired Technologies department has a significant impact on CableLabs’ goals to provide outstanding support and innovation to Member Operator companies so that they can deploy the best and most efficient technology possible in their networks, as well as providing forward looking technology options for future directions they might take to enhance their network providing more capacity and improved user experiences.
Why This Role Is Exciting
The area of focus for this position is to participate in multiple projects utilizing Broadband RF signals that are used in Access Cable networks, such as DOCSIS® 3.0/3.1/4.0 technology and the set up and turn up of simulated plants with nodes and amplifiers.
What You’ll Do
- Build and troubleshoot an active (amplified) cable plant to simulate DOCSIS 4.0 scenarios to support testing for operators.
- Develop test scenarios for the cable plant to exercise DOCSIS 4.0 scenarios focusing on multiple profiles on OFDM channels and OFDMA channels to 1.8 GHz, including a solution for generating noise that will cause a Core (CMTS) change a modems RF profile.
- Develop a plan for FDX technology to test sounding and the algoritms to determine multiple Interference Groups on a cable plant.
- Create simulations of signals going through the amplifier cascade to look at scenarios and measure end-of-line parameters such as BER, MER, and EVM as baselines of best performance.
- Investigate solutions using an Echo Canceller as a Zero Hz diplex filter.
Qualifications
What Is a Must Have
- Minimum Bachelor’s degree in Computer Science and Engineering.
- Familiarity with the use/calibration and programming of lab test equipment such as RF vector spectrum analyzers, Network analyzers, packet testers, signal generators etc.
- Extensive RF troubleshooting skills.
- Familiarity with Simulation programs for RF signals and systems to model scenarios especially using OFDM and QAM signals, to create models calculating BER, MER and EVM.
- Familiarity and use of MATLAB and Simulink.
- Excellent communication and collaboration skills, with the ability to work effectively in a dynamic, cross-functional environment.
- Open to exchange ideas, try out prototype new concepts.
- Ability to lift 30lbs without difficulty (needed to potentially move instruments around)
What Will Set You Apart:
- Familiarity with a range of RF signal generators and analyzers.
- Projects in the design and construction of RF Hardware.
- MATLAB (or equivalent) and Python/Go programming.
