Tenzing Communications

Tenzing Communications

Tenzing Communications of Seattle was founded in 1999 by software developer Simon "Symonty" Gresham, with the backing of Airbus. The firm had intended to launch in-flight data services, including text messaging, instant messaging, and email using broadband satellite receivers using Inmarsat's fourth-generation (4G) system. However, the satellites were not launched until March 2005 ( I4 F1 ), November 2005 ( I4 F2 ) and planned April 2008 for the final Pacific Ocean Region, I4 F3.

In the interim, Tenzing deployed a very-low-bandwidth system in partnership with Verizon AirFone’s radiotelephone network. This system was in commercial operation on United Airlines and a few other U.S. carriers for more than a year before being discontinued.

In 2004, Tenzing merged its operations into a new company, OnAir, formed with SITA and Airbus. OnAir originally intended to introduce broadband and in-flight cell services in 2005, but further delays in Inmarsat's satellite launches and other factors have put inflight trials back until early 2008 and first announced launch customer on Kingfisher Airlines mid 2009. At that time it plans to offer an in-flight cell GSM phone service, at international roaming rates.
