Google Project Loon using 2400 and 5800 MHz

Project Loon is a research and development project being developed by Google with the mission of providing Internet access to rural and remote areas using High-Altitude Balloons (HAB) placed in the stratosphere at an altitude of about 20 km to create an aerial wireless network with up to 3G-like speeds.

The solar powered balloons are expected to stay aloft for over 100 days at a time and support not only air-to-ground Internet communications but also balloon-to-balloon communications enabling the signal to be relayed if required by several balloons to a ground-based station connected to an ISP then onto the global Internet.

Google plans to sending up 300 balloons transmitting on 2400 MHz and 5800 MHz around the world at the southern fortieth parallel that would provide coverage to New Zealand, Australia, Chile, and Argentina.

The company hopes to eventually have thousands of balloons flying in the stratosphere at an altitude of 20 km.

The first 30 balloons are being launched from New Zealand -
