This post covers frequency, walls and satellites. The companies appear because they hold the licenses, and the physics works the same for every owner.
Key Summary Takeaways
· Low Band Passes Through Walls: Lower-frequency signals lose less energy in drywall, brick, and glass than higher bands.
· Distance Weakens Satellite Signals: A satellite signal travels roughly 480 to 550 kilometers to reach your phone, and a wall takes more of it.
· Spectrum Deals Show the Stakes: SpaceX agreed to pay about $17 billion for EchoStar's licenses, and Grain Management reportedly wants about $6 billion for its 800 MHz licenses.
· Expect Coverage Gains First: Rural homes, trails, and open water gain the most, with text and voice arriving before fast data.
In August 2007, I wrote that the FCC's 700 MHz spectrum drew heavy interest because it travels long distances and passes through walls. The auction closed in March 2008 with $19.6 billion in bids. Dish Network won 168 licenses for $712 million, and a Credit Suisse analyst questioned whether the band suited Dish at all. Nineteen years later, the same property is why a rocket company is shopping for spectrum.
Start with how your phone service works today. A cell tower has antennas that send and receive radio signals. Your phone connects to the closest tower, and the tower connects to the carrier network over fiber. Each carrier holds FCC licenses for specific radio frequencies, and that set of frequencies is the spectrum. A tower covers a limited area, so carriers build thousands of them. Where no tower exists, or where a storm knocks out its power, your service stops.
Frequency decides how a signal behaves. Low-band signals, generally below 1 GHz, travel farther and pass through drywall, brick, and glass with less loss. Mid-band and high-band signals carry more data but cover less distance and struggle with walls. A low-band signal can reach the middle of your house. A high-band signal can drop at the front door.
Phone service from satellites has a distance problem. A Starlink satellite orbits roughly 480 to 550 kilometers up and crosses your sky in minutes. Its signal arrives weak, and your phone answers with a tiny antenna and little power. One satellite also covers a large area, so many phones share its capacity. Satellite texting on current phones already works this way, and it asks you to point the phone at open sky. A wall takes the rest of the signal.
That is why 800 MHz matters. T-Mobile sold its 800 MHz licenses to Grain Management in a swap that closed in August 2026. On October 8, 2026, SpaceX announced a definitive agreement to acquire Grain Management's nationwide 800 MHz spectrum portfolio. The deal still needs FCC approval, and SpaceX did not disclose terms. The Wall Street Journal reported a price of $8 billion. In 2025, SpaceX agreed to pay about $17 billion for EchoStar's licenses, and Boost Mobile customers get access to Starlink service as part of that deal. AT&T, Verizon, and T-Mobile shares fell 4 to 5 percent that day.
Here is what it could mean for you. Coverage reaches places towers do not: rural homes, trails, and open water. Service continues when a storm takes down local towers. Expect text and voice first, with data slower than a tower provides, because satellites share capacity across wide areas. You will need a phone that supports the band. Many current phones already support nearby 800 MHz bands, but check yours. You will also need a plan that includes satellite access. Whether competition lowers your bill is unknown. Cities will still run mostly on towers.
In January 2008, I wrote about public safety networks that survive disasters by not relying on a single network. Satellite coverage on an ordinary phone adds another network to your phone without adding another device.
The physics in my 2007 post still holds. The 700 MHz buyers were carriers building towers. Some of the next buyers build rockets.
