Air India’s recent announcement to roll out free in-flight Internet services on select domestic and international flights marks a significant step in enhancing passenger experience. Here’s an explanation of how this service works and the technologies behind it.
Aircraft Equipped with Wi-Fi
Currently, Air India’s in-flight Wi-Fi is available on:
- Airbus A350
- Boeing 787-9
- Select Airbus A321neo aircraft
These planes are equipped with the necessary hardware to enable Internet connectivity, a feature introduced on international flights as part of a pilot program and now extended to domestic routes.
Technologies for In-Flight Connectivity
- Air-to-Ground (ATG) Technology
- Uses cellular towers to provide Internet signals to aircraft.
- An antenna, typically located on the plane’s belly, picks up these signals from ground towers.
- Works well over populated areas but is limited over large water bodies or remote regions without cellular towers.
- Satellite-Based Connectivity
- Uses satellites to transmit Internet signals to aircraft.
- An antenna on top of the plane receives signals from satellites, which relay data between ground stations and the aircraft.
- Offers broader coverage, especially in areas without ground infrastructure.
How In-Flight Wi-Fi Works
- Passengers connect to the ‘Air India Wi-Fi’ network via their devices.
- They are redirected to an Air India portal where details like PNR and last name are required.
- Once authenticated, Internet access is granted.
The system works through:
- Cabin Antennae: Receive signals from passengers’ devices.
- Onboard Server: Processes these signals.
- Transmission: Signals are relayed either to satellites (for satellite-based systems) or directly to ground towers (for ATG systems).
Challenges with Speed
- In-flight Internet speeds are often slower than on the ground due to bandwidth limitations and transmission distances.
- Newer technologies aim to improve this.
Costs for Airlines and Passengers
- For Airlines:
- High initial costs to install antennae and retrofit older aircraft.
- Air India’s $400 million retrofit program includes installing connectivity equipment.
- For Passengers:
- Globally, many airlines offer limited free Internet or charge for additional data.
- Complimentary Wi-Fi for economy passengers is rare due to high operational costs.
Air India currently offers free Wi-Fi as an introductory service but may charge in the future, aligning with global trends to use in-flight connectivity as a source of ancillary revenue.
Future Prospects
With growing demand, in-flight Internet is becoming a standard offering, especially among full-service carriers. For Air India, it represents a move towards modernizing services and meeting international benchmarks under the Tata Group’s vision for global competitiveness.
