Globalstar Gets Approval For Terrestrial Service

Satellite phones provider Globalstar has received permission from the FCC to add a terrestrial component to their service. The company can now use a portion of its spectrum for terrestrial base stations that will provide service to urban areas satellite phone signals normally cannot reach. Once base stations are installed, Globalstar will offer a modified version of current satellite / cellular dual mode handsets to take advantage of the new infrastructure. Globalstar is not the only company looking at this technology, Mobile Satellite Ventures recently announced they plan to offer a similar service.
The FCC has now granted Verizon, US Cellular, and T-Mobile permission to expand their 4G network capacity by temporarily using radio frequencies that are licensed to other companies, but had been sitting unused prior to the current pandemic. The unusual move by the FCC will help support the unprecedented number of people suddenly using wireless broadband to operate from home during the COVID-19 pandemic.

The FCC this week granted permission for initial commercial service to commence in the unlicensed part of band 48, also known as CBRS, a radio frequency band spanning the range of 3550 - 3700 MHz. In a new and unique arrangement, consumer phones will be able to cellular technologies like LTE in an unlicensed band that also has incumbent users such as the military and satellite operators.

Virginia startup Lynk Global has successfully demonstrated new technology that allows satellites in low-earth orbit to communicate directly with standard, unmodified mobile phones on the ground. In multiple verified tests starting February 24th, Lynk was able to broadcast an emergency alert containing a text message from one of its test platforms orbiting in space, using standard GSM technology, which was successfully received by an off-the-shelf Android phone in the Falkland Islands.

FCC Chairman Ajit Pai has released details of the FCC's proposal to re-arrange the C band, making available 280 MHz of additional radio spectrum for 5G in the US. The C band is a 500 MHz segment of spectrum from 3.7 to 4.2 GHz, which is currently used by fixed satellite companies to beam content to video and audio broadcasters, cable systems, etc.
Seems a dual mode phone would make more sense
to have dual mode phones are very good, but there needs to be more coverage and cellular coverage in doors and in many places are hurting. perhaps satelite can help.
What does everyone think?
