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 an intermediate routing specialist certification from Nokia that recognizes professionals who deliver both residential and business communication services.

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 these results are a snapshot in time, and several factors affect the results. 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.

iNARTE is the International Association for Radio, Telecommunications and Electromagnetics, an industry group founded in 1982 to develop and implement a certification program for telecommunications engineers and technicians. Since then, iNARTE has added certifications for wireless system installers and product safety engineers and technicians, among others. After its merging with RABQSA International in 2012, the two organizations are known formally as Exemplar Global.

The iNARTE Telecommunications certification program includes the Telecommunications Technician and Telecommunications Engineer credentials, geared toward many facets of the industry, including networking (LAN and WAN), cellular and satellite. Both have Junior, Senior and Master credential levels.

Each level of the Telecommunications Engineer certification requires an increased number of years in the workforce. The Junior level requires at least four years of related work experience, the Senior level requires six years, and the Master requires eight. Candidates can substitute four years of work experience with an engineering or science college degree approved by the iNARTE Certification Review Board. Each level also requires the candidate to provide references from one supervisor and two or three peers and to pass an exam.

Once you achieve the Junior Telecommunications Engineer credential, you can upgrade to the Senior level by meeting all requirements, and will pay a lower rate for the exam. The same applies to an upgrade from the Senior level to Master. To maintain membership and be listed in the iNARTE Certified Professionals database on the organization's website, candidates must renew annually.

Nokia, formerly Alcatel-Lucent, is a well-known provider of IP network infrastructures. The company prepares networking professionals to support residential broadband, business VPNs, mobile core and backhaul, and cloud-based networks through its Service Routing Certification Program.

The Nokia Network Routing Specialist II (NRS II) certification, a step above the foundational NRS I certification, focuses on Nokia service routing, including IP routing protocols and IP/MPLS protocols, virtual private networking, resiliency techniques, implementing Nokia Layer 2 and Layer 3 services, and IP/MPLS networking.

To achieve the certification, candidates must pass four written exams and a rigorous 3.5-hour NRS II practical lab exam. Passing the first written exam – Nokia Scalable IP Networks (4A0-100) – earns you the NRS I. Several Cisco and Juniper certifications count as credit toward NRS II written exams. For example, candidates with a current CCNP Service Provider certification are exempt from the Nokia Scalable IP Networks exam. Having the Juniper Networks Certified Internet Expert (JNCIE-SP) certification lets you skip three of the Nokia written exams. See the Nokia webpage on credit for other IP certifications for details.

The NRS II certification is valid for three years. To recertify, candidates must achieve a higher-level certification, pass a written exam for a higher-level certification, or pass the Nokia NRS II Composite Exam.

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.

In addition to our top five certifications, vendor-neutral credentials that merit attention are the Telecommunications Electronics Technician (TCM) by the Electronics Technicians Association and the NCTI Master Technician professional certifications. Candidates earn three or four college credits for each NCTI Master Technician credential.

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 is 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.
