John Hopkins University

What you'll study

This master’s programme combines advanced theory with hands‑on practice in networking and telecommunications. Core topics typically include network architecture and protocols, wireless and mobile communications, network security, performance analysis and traffic engineering, and telecom systems (including optical and satellite communications). Students also study supporting areas such as distributed systems, network programming, signal processing for communications, and quality‑of‑service techniques.

• Core coursework covering fundamentals of routing and switching, transport protocols, and network modelling.
• Electives in wireless networks, cellular systems, software‑defined networking (SDN) and network function virtualisation (NFV).
• Security and privacy modules addressing cryptography, secure network design and intrusion detection for telecommunication infrastructure.
• Lab and project components with packet‑level analysis, hands‑on configuration of routers/switches, and programmable data plane experimentation.
• A substantial capstone project or thesis that applies theory to a practical networking or telecoms problem, often in collaboration with industry or research groups.

Instruction emphasises current industry practices and research advances, giving students opportunities to work with experimental platforms, simulation tools and testbeds relevant to service providers, cloud operators and wireless providers.

Entry requirements

Applicants are expected to hold a recognised undergraduate degree in computer science, electrical/computer engineering, information technology or a closely related field. Strong preparation in programming, data structures, probability and linear algebra, and basic networking concepts is normally required.

• A bachelor’s degree from an accredited institution in a relevant subject.
• Academic transcripts demonstrating technical coursework in computing, mathematics or engineering.
• A current CV or résumé outlining relevant academic, research or professional experience.
• Academic references (usually two) that can speak to technical ability and potential for graduate study.
• A personal statement describing motivations, relevant experience and intended area of focus within networking and telecommunications.
• For applicants whose first language is not English, evidence of English proficiency is required (such as IELTS or TOEFL scores).

Some applicants with substantial professional experience in networking or telecoms may be considered even if their undergraduate background is not strictly in computing/engineering; prerequisite bridging coursework can be advised as needed.

Career prospects

Graduates are prepared for technical and leadership roles across the telecommunications and networked systems sectors. Typical career paths include:

• Network engineer or architect for internet service providers, telecom operators and large enterprises.
• Systems engineer or infrastructure specialist in cloud and data centre networking.
• Wireless communications engineer working on 4G/5G/next‑generation cellular systems and IoT connectivity.
• Network security engineer focusing on secure design, incident response and resilient telecom infrastructure.
• Systems or research engineer in companies developing SDN, NFV, optical networks or programmable networking hardware.
• Research or doctoral study in networking, communications or related areas for those aiming at academic or advanced R&D careers.

Alumni find roles at network equipment vendors, cloud providers, telecommunications companies, defence and aerospace contractors, and technology start‑ups, as well as research institutions.
