Modem information
What do modems do?
What is a modem?
A Modem job typically involves developing, testing, and optimizing modem hardware and firmware for wireless communication. Engineers in this role work on signal processing, network protocols, and performance tuning for technologies like 4G, 5G, and Wi-Fi. They collaborate with software and hardware teams to ensure seamless connectivity and efficient data transmission. Strong knowledge of telecommunications, embedded systems, and programming languages like C/C++ is often required.
What is the difference between Modem vs Network Technician?
| Aspect | Modem | Network Technician |
|---|---|---|
| Required Credentials | Basic technical knowledge, certifications like CompTIA A+ often preferred | Networking certifications such as Cisco CCNA, CompTIA Network+ |
| Work Environment | Customer homes, service provider facilities | Offices, data centers, client sites |
| Industry Usage | Telecommunications, internet service providers | IT, networking, telecommunications |
| Common Search/Comparison | Yes | Yes |
While both roles involve working with network equipment, a Modem primarily focuses on installing and troubleshooting modems for internet access, whereas a Network Technician handles broader network infrastructure, including routers, switches, and network configurations. Understanding these differences helps in choosing the right career path or service provider for your networking needs.
What are some common challenges faced by modem engineers, and how can they be addressed?

Job description
Telesat Lightspeed, our revolutionary Low Earth Orbit (LEO) satellite network, scheduled to begin service in 2027, will revolutionize global broadband connectivity for enterprise and Government users by delivering a combination of high capacity, security, resiliency and affordability with ultra-low latency and fiber-like speeds. Telesat is headquartered in Ottawa, Canada, and has offices and facilities around the world.
The company's state-of-the-art Satellite fleet consists of 12 GEO satellites, the Canadian payload on ViaSat-1 and one LEO 3 demonstration satellite. For more information, follow Telesat on X and LinkedIn or visit www.telesat.com
The successful candidate will bring engineering expertise in the design and deployment of satellite antennas and user terminals (UTs) for the Telesat Lightspeed Constellation network, supporting both fixed and mobile applications. This role involves complete analysis of terminal antenna options, modem integration, and UT architecture to provide technical inputs for deployment and portfolio development. The candidate will also lead technical relationships with antenna suppliers and participate in design reviews and validation tests.
Resource is required to work onsite from our Bethesda office four (4) days weekly.
Main Responsibilities
- Develop technical requirements for LEO Constellation UT antenna technology, including modem integration and antenna architecture
- Support the definition of UT antenna and modem requirements, evaluate vendor developed technologies
- Interface with and evaluate vendor-proposed terminal designs for performance, reliability, manufacturability, and review integration strategies between antennas and modems for future UT designs
- Recommend modifications or new UT designs to achieve cost, performance, and reliability targets
- Identify tests to validate system assumptions with antenna and UT prototypes
- Help develop supporting documentation, test requirements and compliance matrix for UT Type Approval process
- Lead evaluation of antenna technologies, including electronically steerable antennas (ESAs) and novel ESA technologies
- Stay current with the latest satellite, 5G antenna design technologies, and open AMIP and open BMIP standards
- Perform other duties as required
Education and Experience
- Bachelor's in Electrical Engineering, Physics, or similar - required
Master's in Engineering - required - PhD with research on electronically steerable antenna design - highly preferred
- Minimum 10 years in satellite antenna, terminal, and/or satellite system design
- Experience with ESA design and modem integration is a strong plus
- Deployment of ESA designed antennas is a strong plus
Specialized Knowledge, Skills, and Abilities
- Simulation, design, and testing of electronically steerable antennas for satellite communication
- Knowledge of flat panel antenna integration approaches with variety of modem technologies
- Familiarity with standardized protocols for antenna control and modem interoperability and communication
- Expertise in Ka-band antenna technologies for mobile land, aeronautical, maritime, and fixed applications
- Understanding of satellite modems, hub technology, and RF equipment
- Strong foundation in electromagnetism and array antenna architecture
- Experience with RFIC selection, beamforming, and manufacturing processes for array antennas
- Knowledge of antenna control techniques for beam steering and beam shape control
- Ability to make design trade-offs between performance, cost, and power consumption
- Experience working with suppliers and vendors of antenna and modem technologies
- Fluent in English, written and oral
Working Conditions
- Resource is required to be in office four (4) days weekly
- Occasional international travel is required in this role
- Must qualify for government clearance
