The Pros and Cons of Two Different D2D Satellite-to-Cellphone Paths

Mobile service providers that decide to offer satellite-to-cellphone service can choose between two primary paths. They can let a satellite operator use some of their cellular spectrum or they can use spectrum intended for satellite use—spectrum that typically is controlled by the satellite operator. A new report from Analysys Mason explores the pros and cons of the two direct-to-device options. Overall, Analysys Mason favors the use of satellite spectrum. The authors point to a high level of global alignment for the satellite spectrum bands, known as the L-band and S-band. But not all countries have taken the necessary regulatory steps to allow providers to use cellular spectrum for satellite communications. The authors also argue that the use of satellite spectrum is less likely to cause interference with cellular network operations.
