Alphabet uses lasers to connect internet in hard-to-reach areas of India


Internet without wires: Alphabet uses lasers to connect the Internet in remote areas of India

Laser terminals will be able to transmit a signal through the atmosphere over long distances, not inferior in speed to standard methods.

Alphabet has announced a partnership with Indian operator Bharti Airtel to use laser terminals to transmit data through the atmosphere. The project called Project Taara has been developed since 2019.

Alphabet has decided to use lasers to bridge gaps in its terrestrial network infrastructure. Taara laser terminals serve as large optical transmitter-receivers that transmit information through the atmosphere to another terminal. At one end, the Taara terminal is connected to a small remote network, and at the other end it is connected to the existing network infrastructure of the service provider and acts as an uplink.

According to Alphabet, this technology will expand access to the Internet in places where the deployment of traditional optical infrastructure is either difficult or uneconomical, such as across rivers or rough terrain. In addition, laser terminals can be used in densely built-up urban environments.

The first partner of Alphabet in the Taara project was the Indian telecommunications operator Bharti Airtel. Over the next few months, Airtel plans to deploy Taara optical links in both rural and urban areas of India.

Alphabet claims that Taara’s laser terminals are capable of transmitting up to 20Gbps of data, on par with typical passive optical networks (PONs) typically deployed by broadband service providers. The company also claims that the technology can transmit 30 times more data than is possible using the radio spectrum.

However, this technology has its own problems. One of the more obvious ones is the potential loss of signal due to environmental factors such as weather, air quality, and other obstacles that interfere with lasers. According to the Project Taara team, many of these problems have been eliminated by modulating the laser power and adjusting the data processing.
