Have you ever wondered why your phone shows full signal bars on your balcony, but as soon as you step into your living room or office, it drops to a single bar or shows "No Service"? In Mumbai, network dropouts affect subscribers of all major carriers: Reliance Jio, Bharti Airtel, and Vodafone Idea (Vi).
Carrier Frequencies: Why Jio and Airtel Suffer Indoors
To understand why network drops happen, we must look at the frequency bands allocated to telecom operators. Higher frequencies can transmit more data, but they have short propagation distances and suffer from high attenuation when passing through obstacles:
- Reliance Jio: Operates a purely digital 4G LTE/5G network. It uses Band 3 (1800MHz), Band 40 (2300MHz), and Band 5 (850MHz). Band 3 and Band 40 carry the bulk of Jio's data traffic but struggle to penetrate thick concrete walls.
- Bharti Airtel: Uses 900MHz for legacy voice, 1800MHz/2100MHz for VoLTE and 4G, and high-frequency C-band for 5G. Airtel users frequently experience dropped calls in basements because high-frequency signals cannot penetrate underground.
- Vodafone Idea (Vi): Relies heavily on the 900MHz band for voice coverage and 1800MHz/2100MHz for 4G. While Vi's voice signal is relatively stable, its high-speed data transmission suffers inside buildings.
How a Dedicated Signal Booster Resolves the Problem
A dedicated mobile signal booster, such as our 4G LTE Signal Booster, bypasses physical obstacles by capturing the signal outside and distributing it indoors.
The booster unit amplifies the carrier bands with high gain (typically 60dB to 70dB), providing a strong and stable connection inside the building. This resolves call drops, broken audio, and slow data speeds permanently.
