The Federal Communications Commission (FCC) is set to vote on a significant order next month, which may pave the way for the auction of crucial mid-band spectrum in 2024. Mid-band spectrum is vital for the advancement of 5G connectivity, and its availability could alter the competitive landscape among the major U.S. wireless carriers: T-Mobile, Verizon, and AT&T.
How T-Mobile's Strategic Choice Differed from Verizon and AT&T
During their initial 5G rollout strategies, both Verizon and AT&T opted for millimeter wave (mmWave) spectrum, which offers impressive data speeds. However, they overlooked a critical limitation of mmWave: its signals travel short distances and are easily blocked by physical obstructions like buildings and trees.
T-Mobile, led by Chief Technical Officer Neville Ray, made a different, more strategic choice by focusing on mid-band spectrum. Although mid-band may not deliver the same peak speeds as mmWave, it provides a more balanced trade-off between coverage and speed, earning its reputation as the "Goldilocks of 5G."
Verizon and AT&T's Response: Acquiring Mid-Band Spectrum
Recognizing their miscalculation, Verizon and AT&T quickly pivoted, investing over $68 billion combined in the FCC's C-Band auction to secure essential mid-band licenses. This strategic shift allowed T-Mobile to establish itself as a 5G frontrunner in the U.S., a position it continues to maintain.
The FCC's Upcoming Auction Vote on Mid-Band Spectrum
On July 22, the FCC will vote on whether to proceed with an auction of 160 MHz of spectrum in the Upper C-Band, slated for 2027. Following recent legislation mandating the auction of at least 100 MHz, the FCC aims to offer significantly more spectrum than legally required, resulting in billions in potential auction revenue.
The demand for wireless connectivity across smartphones, connected devices, and emerging technologies like self-driving vehicles underscores the urgency for mid-band spectrum. Its advantageous blend of performance and coverage makes it ideally suited for 5G technologies, highlighting its importance in the telecommunications landscape.
Given that the Upper C-Band is currently used for critical satellite operations and airline altimeters, there are concerns about potential interference with aircraft systems. This was a significant issue when AT&T and Verizon initially acquired C-Band spectrum and were forced to address interference problems with airlines.
Expectations for Bids from Major U.S. Carriers
As the auction approaches, we anticipate the active participation of the "Big 3" carriers—Verizon, T-Mobile, and AT&T. While they may seem to have ample mid-band spectrum, the reality is that ongoing demand and competition mean they will likely pursue additional assets to bolster their networks.
