The Tanzanian islands of Zanzibar and Pemba will be a test site for creating a mobile Internet network using balloons. The project is being prepared by the British company World Mobile. Currently, only about 20% of Tanzanians use the Internet, which is low even in South Africa.
World Mobile is launching a hybrid network using balloons in Zanzibar and Pemba, which should provide almost complete coverage of the islands .
Two balloons filled with helium will fly at an altitude of 300 meters above the ground, providing a broadcast radius of about 70 kilometers each. The frequencies of 3G and 4G standards will be used to broadcast the signal. The equipment installed on them will be powered by solar panels. The balloons will be able to withstand heavy winds of up to 150 kilometers per hour and stay in the air for up to 14 days before descending to refuel.
The power of the Internet distributed from balloons will be enough for tasks such as browsing web pages and email.
