Most frequent fliers would have been familiar with the requirement to power off personal electronic devices (PEDs) for the duration of domestic flights. It was not until 2014, that Indian fliers were permitted to operate mobile phones and other PEDs on “flight mode” (in non-transmitting mode). The rationale for this restriction, as explained by the Directorate General of Civil Aviation (DGCA), is that radio transmitters in most communications devices may, and have in the past, caused harmful interference with crucial on-board flight systems. Therefore, while several Indian carriers such as Jet Airways already provide on-board Wi-Fi services, such services are limited to the provision of locally stored content to airborne PEDs, and do not enable passengers to connect to the internet cloud.
However, recent technological developments have now made it possible for passengers to use transmitting PEDs while airborne, without causing harmful interference to crucial flight operation systems or terrestrial communication networks. Together these technological solutions are labelled In-Flight Connectivity (IFC) services. Typically, IFC solutions are provided by making use of aeronautical mobile satellite services that use a satellite link to provide IFC to onboard PEDs; or by using Mobile Communications on-board Aircraft (MCA) systems, which while typically operating on terrestrial GSM communications bands, use an air-to-ground satellite link to establish connections with terrestrial networks.
