Iridium is the latest service provider to propose use of spectrum sharing rather than exclusive licensing to expand the amount of bandwidth available for communications purposes. In a recent filing with the U.S Federal Communications Commission, Iridium has withdrawn a request for exclusive use of new spectrum and instead proposes that Iridium and Globalstar share spectrum in the 1.6 GHz band.
Under the proposal, Iridium and Globalstar would have shared access to the spectrum at 1616-1618.725 MHz, and Iridium’s exclusive spectrum assignment at 1618.725-1626.5 MHz would remain unchanged.
Globalstar apparently opposes the spectrum sharing proposal. As with other spectrum sharing proposals, Iridium argues the advantage is that the two companies could immediately deploy services in the shared spectrum without having to reassign any spectrum for exclusive use.
Globalstar likely opposes the sharing proposal as repesenting value only for Iridium, not Globalstar, at the moment.
