"Eliminate Dead Zones": Elon Musk Partners With T-Mobile For New Satellite-To-Cell-Service
"Eliminate Dead Zones": Elon Musk Partners With T-Mobile For New Satellite-To-Cell-Service

Elon Musk's SpaceX teamed up
with T-Mobile CEO Mike Sievert to beam cell service via Starlink satellites to
"most
places in the US," including more than half a million square miles of
dead zone areas that aren't covered by cellular networks.
The two companies would
create a new mobile network to broadcast T-Mobile's existing mid-band spectrum
via Starlink satellites to anywhere in the continental US, Hawaii, parts of
Alaska, and Puerto Rico.
SpaceX and T-Mobile wrote in
a press
release that the new network would "provide near complete
coverage in most places in the US — even in many of the most remote locations
previously unreachable by traditional cell signals."
Musk tweeted that the new
service, launching in 2023, will "eliminate dead zones
worldwide."
Bloomberg explained
how the new satellite-to-cellular service would work through powerful antennas
attached to upgraded Starlink satellites:
The new network will be
accessible thanks to large, powerful antennas attached to Starlink satellites.
Musk said each antenna would measure some 25 square meters (269 square feet)
and be "extremely advanced because they've got to pick up a very quiet
signal from your cell phone and then be caught by a satellite that's traveling
17,000 miles an hour." The T-Mobile service will run in a similar way to
data roaming, where a user's mobile will scan for service and if it finds none
it will connect to the satellite.
Musk, at an unveiling event
at SpaceX's Starbase in Boca Chica, Texas, along with T-Mobile Sievert, on
Thursday evening, gave an "open invitation to carriers around the
world" about adding the new service.
Bloomberg noted that most
smartphones are already equipped with technology to beam a signal to space so
that additional equipment won't be required.
But there are limitations,
and the main issue is bandwidth, as Bloomberg pointed out:
The main issue is bandwidth,
which will at first limit the service to text messaging. The coverage area will
be divided into large cell zones, with each zone's connectivity limited to
around 2-4 MBs. Musk said that would allow for some 1,000-2,000 voice calls per
cell, or millions of text messages, but the service would not provide a
substitute for ground cell stations.
"This is really meant to
provide basic coverage to areas that are currently completely dead," Musk
said, adding there could initially be a delay of "half an hour, maybe
worse" for messages to pass through the system.
Testing for the new
satellite-to-cellular service is expected later this year after SpaceX launches
the new satellites into low Earth orbit.
