It will make a Ku-band system available to its airline partners in the Interim. The other U.S. commercial in-flight Internet service,
, has always used Ku-band satellites for connectivity.
Climate Change Could Threaten Wireless Connections
Damian Carrington, writing in the Guardian, reports
Climate change 'threatens UK Wi-Fi connections', says government report – Study into impact of hotter, stormier weather on UK infrastructure finds threat to Wi-Fi range and signal strength
. The article says, "The government acknowledges that the impact of climate change on telecommunications is not well understood, but the report raises a series of potential risks. In addition to the impact on range and reliability, warmer temperatures and more intense storms may cause communications infrastructure to be flooded, or damaged by an increase in trees falling onto overhead lines. There is even the suggestion that changes in the plants that grow in the U.K. could affect how radio waves travel." The report is available at
