In recent weeks, there have been reports that the United States is exploring the possibility of sending internet services to Cuba using high-altitude balloons. The move comes in response to the Cuban government’s decision to restrict internet access amid ongoing protests regarding civil rights violations and shortages of food and medicine. The disturbances, which have been fuelled by dissatisfaction with the government’s handling of the Covid-19 pandemic, show no signs of abating.
A Deeper Understanding of High Altitude Balloons for Internet
High altitude balloons, or ‘Loon Balloons’ as they’re commonly known, first came into use under Project Loon. These balloon-like contraptions, made from everyday plastic polyethylene, are roughly the size of a tennis court and are powered by solar panels. Controlled by software on the ground, these balloons, floating cell towers, transmit internet signals to ground stations and personal devices.
They ascend to heights between 60,000 and 75,000 feet above the Earth’s surface, well past commercial flight routes, and remain operational for at least one hundred days before being returned to earth for maintenance. Despite their durability, these balloons need to be replaced about every five months, owing to the harsh conditions in the stratosphere.
Prerequisites for Balloon-based Internet Transmission
To effectively transmit the internet through these high-altitude balloons, network integration with a telecom provider is necessary. This integration would include certain equipment installed on the ground within the region of operation. Moreover, permission from local regulatory bodies must be obtained prior to the deployment of this system.
Importance of Balloon Internet Services
These balloons provide a more affordable alternative to cable laying or the construction of cell towers, as they allow telecom companies to extend coverage as required. The high-altitude balloons can also enhance internet access in remote and rural areas with limited connectivity options and aid communication during natural disasters.
Challenges and Limitations
The use of high-altitude balloons for internet transmission is not without its difficulties. First and foremost, there’s the need to find an unused band of spectrum or radio frequencies. This is particularly challenging because spectrum use is typically controlled by national governments, thus finding a vacant block that won’t be interfered with is extremely difficult.
Additionally, the long-term economic viability of balloon- or drone-powered networks is questionable. Operational issues such as developing algorithms to accurately map balloon positions, devising strategies to counter adverse weather conditions, and the concern of relying on non-renewable resources, pose significant roadblocks.
About Project Loon
Project Loon, launched in 2011 by Alphabet (Google’s parent company), aimed to extend internet connectivity to remote locations using a network of stratospheric balloons. However, in January 2020, the project was discontinued due to lack of commercial viability. Before its discontinuation, Project Loon successfully provided service in mountainous regions of Kenya via a partnership with a local telecom company. It also assisted in establishing wireless communications in Puerto Rico following the devastating Hurricane Maria.
While the US’s plan to provide internet access to the Cuban populace is laudable, the path to achieving this goal involves overcoming several practical and regulatory challenges. However, if successful, this technology could revolutionize internet connectivity in remote and underserved regions worldwide.
