Skills required for telecom engineers in India

Essential Skills Every Telecom Engineer Must Master

1. Formal Qualification in Electronics & Communication

To build a solid foundation, you must have a diploma or degree in Electronics & Communication Engineering. These programmes cover critical subjects like analog/digital circuits, communication systems, signals and systems, and microprocessors—essential for all later practical work.

2. Networking Expertise (Routers & Switches)

A telecom engineer needs hands‑on command over networking hardware:

Routers, switches, gateways, and related infrastructure—think LAN, WAN, and WLAN.

⚙️ Practical Tip: Get CCNA or similar certification and practise configuring VLANs, routing protocols (OSPF, BGP), and QoS settings on labs or simulators.

3. MS Office Proficiency for Reporting

Preparing reports, performance summaries, and project presentations is part of daily life.

MS Word for documentation,

Excel for data analysis—e.g., uptime logs, parameter tabulation, and

PowerPoint for stakeholder & client presentations.

Solid Office skills reflect professionalism and efficiency.

4. In‑Depth Knowledge of SMPS, Power Plants & Battery 

Telecom base‑stations require reliable power systems:

SMPS (Switched‑Mode Power Supply) design and troubleshooting, efficiencies up to 99%, EMI issues .

Backup battery systems, charge controllers, site power automation.

These ensure 99% uptime and minimal OPEX/infrastructure failures.

5. Optical Fiber Cable & Network Basics

Understanding fiber is vital:

Fiber is a dielectric waveguide using total internal reflection to transmit light over long distances .

Knowing core, cladding, coatings, single-mode vs multimode, attenuation, splicing, connectors.

 Tip: Practice terminating cables, using OTDR and power meters.

6. Microwave Antenna & Waveguide Fundamentals

Microwave links need clear understanding of RF hardware:

Waveguides are hollow metallic tubes that guide microwaves with minimal loss—ideal for high-frequency microwave systems .

Horn antennas, microwave feeders, and couplers.

Good grasp helps plan site layouts and troubleshoot link degradation.

7. GUI Tools for RF Testing & Optimization

Modern telecom networks rely on software-centric monitoring:

RF testing platforms (e.g., TEMS, Atoll, iPerf)

GUI‑based tools for drive testing, spectrum analysis, parameter tuning, and optimization workflows.

Ability to interpret KPIs (RSRP, SINR, QoE) is essential for network performance tuning.

8. Fiber Modem Configuration

With fiber modem installations becoming common at client premises:

Knowledge of ONT/ONU setup, GPON/XGS‑PON profiles, VLAN tagging, QoS

Basic CLI or Web‑GUI commands to configure, troubleshoot, reset.

Why These Skills Matter 

⚙️ Network Reliability: Equipment downtime hurts services and profits.

🗂️ Documentation: Clear records improve maintenance efficiency.

💡 Troubleshooting: From power to RF, problems need cross-domain expertise.

🌐 Future-ready: Knowledge of fiber, microwave, and RF tools sets you up for 5G, IoT, and advanced network tech.

✅ Final Thoughts

A well-rounded telecom engineer is part electronics expert, part IT/network specialist, and part field technician. Continuously upgrading skills—power systems, fiber optics, microwave waveguides, and RF tools—not only makes you effective today but ensures you stay ahead in the evolving telecom landscape.

Lessons from MTNL’s Fall: A Telecom Case Study for India

 Lessons from MTNL’s Fall: A Telecom Case Study for India

The telecom industry in India has seen meteoric growth over the last two decades. While private players like Jio, Airtel, and Vodafone-Idea dominate today’s market, one name that once stood tall is MTNL (Mahanagar Telephone Nigam Limited). This blog takes a deep dive into MTNL’s rise, peak, and eventual decline—highlighting valuable lessons for businesses and policymakers alike.

📜 Brief History of MTNL

Established in 1986, MTNL was set up by the Indian government to manage telecom services in two major metros—Mumbai and Delhi. It was once known for:

Providing landline and broadband services

Early adoption of GSM mobile services

Being a listed PSU with a strong urban subscriber base

For years, MTNL symbolized urban communication and reliability. But as technology and competition evolved, MTNL struggled to keep pace.

📈 The Rise: MTNL’s Golden Era

During the early 2000s:

MTNL was among the first in India to launch 3G services (2008)

It had a stronghold in the metros with lakhs of landline users

Known for affordable broadband and “Trump” prepaid services

Its early technological adoption was admired globally. It also had government backing and a loyal urban user base.

📉 The Fall: What Went Wrong?

1. Lack of Innovation & Investment

Private companies heavily invested in 4G and infrastructure, while MTNL lacked funds and modern tech upgrades.

2. Delays in Decision-Making

Being a PSU, MTNL’s decisions were delayed by bureaucracy and government policies.

3. Poor Marketing Strategy

MTNL failed to rebrand itself in the digital era. Younger audiences moved toward aggressive, tech-savvy brands.

4. Mounting Debts

By 2020, MTNL had over ₹20,000 crore in debt, struggling to pay salaries and maintain networks.

5. Staffing Crisis

Heavy workforce with high salaries but limited productivity. No downsizing or retraining strategy was implemented.

6. Limited Service Area

Unlike BSNL, MTNL operated only in Delhi and Mumbai, limiting revenue opportunities.

7. Inadequate Customer Support

Slow complaint resolution, poor digital platforms, and outdated billing systems led to mass churn.

🧠 Key Lessons from MTNL’s Decline

1. Adapt or Perish

In the fast-paced tech sector, stagnation is death. MTNL couldn’t pivot to modern services like 4G or fiber fast enough.

2. Bureaucracy Can Kill Innovation

Too many layers of approval can prevent timely decisions, especially in tech and telecom.

3. Customer Experience Matters

Consumers want fast, reliable service and digital tools—not legacy systems and long queues.

4. Privatization Isn’t Always Evil

Government-run firms need freedom and competition mindset to survive.

5. Diversification Is Essential

MTNL focused only on landline and GSM while rivals expanded into fiber, digital apps, and content streaming.

🔮 What’s Next for MTNL?

In 2019, the government announced a merger between MTNL and BSNL to revive both firms. As of 2025:

The merger is still in progress

MTNL services continue in Mumbai and Delhi under BSNL branding

There is no clear message about MTNL employee job security and benefits from government side.
