Wireless Infrastructure Association Reports on Satellite D2D’s Role With Terrestrial Networks

Wireless Infrastructure Association-commissioned reports reviewed satellite direct-to-device service alongside terrestrial wireless infrastructure and concluded that the two technologies play different roles. The assessment centered on where satellite D2D can extend connectivity and where it does not match the properties of terrestrial networks.

The analysis drew on two independent reports by Mobile Experts Inc. and TMF Associates, titled “Satellite Direct-to-Device: A Supplement for Terrestrial Cell Coverage” and “Will Satellites Replace Cell Towers?” The studies used a practical physics and economics-based assessment of satellite D2D’s capabilities and limitations.

Mobile Experts Inc. reported that satellite signals must travel hundreds of miles between a mobile device and a satellite, which results in weaker connections and challenges for indoor coverage. It also cited capacity limits because satellite beams cover larger geographic areas and shared spectrum must serve more users, along with limited current usage and financial viability compared with terrestrial networks.

TMF Associates said satellite D2D supports coverage expansion in remote and hard-to-reach areas but does not replicate terrestrial networks for speed, capacity, indoor coverage, or reliability. “The physics and economics of wireless networks tell a consistent story that satellites are not a replacement for wireless infrastructure on the ground,” said Joe Madden, President of Mobile Experts Inc. “Satellite D2D can help extend coverage in remote areas, but terrestrial networks will continue to provide the speed, capacity, reliability, and coverage that consumers and businesses expect.” Tim Farrar, President of TMF Associates, said, “The momentum behind satellite innovation has sparked an important conversation about the future of wireless connectivity and the role satellites can realistically play alongside terrestrial networks.” Patrick Halley, President and CEO of WIA, said, “The findings are clear: satellite D2D and terrestrial networks serve different purposes,”

The reports concluded that satellite D2D is best viewed as a complement to terrestrial infrastructure rather than a substitute.
