🧠 Which Is Better for Each Use Case?

---

🧑‍🏫 1. Students (Online Learning)

| ✅ Recommended: Fiber
| 🎓 Reason: Stable video calls, LMS, Zoom, Google Classroom
| ❌ 4G may buffer during peak times or weather issues

---

👩‍💼 2. Remote Workers & Freelancers

| ✅ Recommended: Fiber
| 💼 Reason: Lower latency, supports large file transfers, better VPN reliability
| ❌ 4G may cause dropped calls or app crashes in poor signal zones

---

📺 3. Streaming, Netflix, YouTube, IPTV

| ✅ Both Work, But Fiber Wins
| 📱 Reason: 4K-ready streaming with no buffering
| 🔄 4G: Fine for 720p/1080p but may buffer on multiple devices

---

🎮 4. Gaming

| ✅ 100% Fiber
| 🕹️ Reason: Online games like COD, Valorant, and PUBG require <30ms ping
| ❌ 4G = high ping spikes, lag, and disconnections

---

🏕️ 5. Rural & Outstation Homes

| ✅ Recommended: 4G (for now)
| 🌄 Reason: Fiber not yet available in many villages
| ✅ Use high-gain external antennas for better 4G signal
