Top 5 telecommunications certifications

When it comes to bringing people and systems together, networking is often required to make all the right connections and technologies work. However, there's a lot more than just networking involved in telecommunications certifications and the technologies they cover.

Here, we cover a variety of certifications, including classic telecommunications and telecommunications networking. Our top five picks include a Telecommunications Certification Organization (TCO) credential as well as a vendor-neutral Master Technician credential from NCTI.

You will also read about engineering-oriented communications certifications, such as the Internet Protocol Engineering Professional (IPEP), the iNARTE Telecommunications Engineer and a distribution credential from the Building Industry Consulting Service International (BICSI), originally a building trades association. The BICSI certification is in such high standing that, for some job roles, it's a Department of Defense requirement.

There's more than ordinary networking involved in many of these credentials, because voice and streaming media traffic come with certain unavoidable and important requirements for limited latency and quick delivery. These are necessary for real-time voice and video communications to occur, and for streaming media delivery to provide an acceptable user experience without hiccups. Thus, there's a vital service-level establishment, monitoring and troubleshooting component in these credentials.

There's also a large collection of protocols and services that certified professionals must know to install, configure, manage, and troubleshoot, above and beyond the usual TCP/IP basics commonly found in internet-connected networking environments.

We searched several job boards for telecommunications certifications and compiled those results. Note that they are a snapshot in time, and several factors affect them. For example, you can expect to see fewer listings for the most senior certifications because fewer people possess them. Also, results vary considerably depending on the job board. Although the table below doesn't reflect it, the Cisco CCNA and CCNP and the CompTIA Network+ certifications appear in many telecom job descriptions, along with the featured certs, and, in some cases, are part of the recommended training for our featured certs.

RCDD: Registered Communications Distribution Designer

The Registered Communications Distribution Designer (RCDD) certification offered by Building Industry Consulting Service International (BICSI) is one of several engineering-oriented IT communications credentials from this design and implementation engineering-oriented organization.

Under the Unified Facilities Criteria (PDF available here), the RCDD is required for individuals who work for or with the U.S. Department of Defense on telecom-related design projects. Thus, the RCDD is in reasonably high demand to service that one major source of activity by itself and is also popular with high-end architecture, design, and premises engineering firms.

The RCDD is a long-standing credential; it's been around since 1984 and focuses on the design, integration, and implementation of information and communications technology (ICT) systems and related infrastructure components.

Other BISCI credentials include the following:

  • Registered Telecommunications Project Manager (RTPM)
  • Data Center Design Consultant (DCDC)
  • Outside Plant Designer (OSP)
  • Installer 1 (INST1)
  • Installer 2, Copper (INSTC)
  • Installer 2, Optical Fiber (INSTF)
  • Technician (TECH)

The RCDD certification is valid for three years. To recertify, candidates must earn 45 approved continuing education credits (CECs) and attend at least one BICSI conference as a part of the CEC credits. A renewal fee of $195 if renewing online ($225 if renewing through paper) for members ($325 for nonmembers) applies.

Beyond the top 5: More telecommunications certifications

Once you go beyond the basic IT communications industry certifications such as the RCDD, you'll find that IP-based communications and even pure telecom platforms define a big landscape of possible technical training and certification.

Absent from our list of the top five this year is the Nokia Network Routing Specialist. We chose instead to focus on the NCTI Master Technician because of its broader appeal, but the Nokia credential is still an excellent choice for those working with the Nokia technologies. In addition to our top five certifications, vendor-neutral credentials that merit attention are the Telecommunications Electronics Technician (TCM) by the Electronics Technicians Association.

The Fiber Optic Association (FOA) has a large certification program with a focus on fiber-optic and premises cabling, aimed at technicians, installers and network designers who handle fiber-optic communications systems.

Industry players such as Cisco, HPE and IBM offer large, complex training and certification programs as well, as do purely telecom-oriented vendors. Your interest in, and exposure to, specific platforms and technology solutions will lead you toward available training and certifications offered by each vendor.

There will be no shortage of options, but because hands-on exposure and access are essential to pursue them, it will probably be more obvious and less daunting that we can only point out the huge landscape here in vague and nonspecific terms.
