Working conditions

Some telecom technicians provide in-home installation and repair services, while others work in central offices or electronic service centers. Equipment installation may require climbing onto rooftops and into attics, and climbing ladders and telephone poles.

Telecom technicians occasionally work in cramped, awkward positions, in which they stoop, crouch, crawl, or reach high to do their work. Sometimes they must lift or move heavy equipment and parts. They also may work on equipment while it is powered, so they need to take necessary precautions.

Injuries and Illnesses

The work of telecom technicians can be dangerous. Telecommunications equipment installers and repairers have one of the highest rates of injuries and illnesses of all occupations.

Common injuries include falls and strains.

To reduce risk of injury, workers wear hardhats and harnesses when working on ladders or on elevated equipment. To prevent electrical shocks, technicians may lock off power to equipment that is under repair.

Work Schedules

Most telecom technicians work full time.

Minimum qualifications

Telecom technicians typically need postsecondary education in electronics, telecommunications, or computer networking. Generally, postsecondary programs include classes such as data transmission systems, data communication, AC/DC electrical circuits, and computer programming.

Most programs lead to a certificate or an associate’s degree in telecommunications or related subjects.

Some employers prefer to hire candidates with an associate’s degree.

Once hired, telecom technicians receive on-the-job training, typically lasting a few weeks to a few months. Training involves a combination of classroom instruction and hands-on work with an experienced technician. In these settings, workers learn the equipment’s internal parts and the tools needed for repair. Technicians who have completed postsecondary education often require less on-the-job instruction than those who have not.

Some companies may send new employees to training sessions to learn about equipment, procedures, and technologies offered by equipment manufacturers or industry organizations.

Because technology in this field constantly changes, telecom technicians must continue learning about new equipment over the course of their careers.

ISCO skill level
