In several top markets, T-Mobile’s millimeter wave (mmWave) spectrum holdings allow them to add incremental 5G capacity. Once activated, the entire 600 MHz LTE coverage area will effectively become a 5G coverage area. The existing 600 MHz capable radios that T-Mobile has been installing over the past year, like the Ericsson 4449, are 5G-ready and that unused portion of 600 MHz spectrum can be activated for 5G with an over-the-air software push. However, some of this spectrum is sitting idle and waiting to be utilized. This greenfield frequency band will largely be the building block for T-Mobile’s nationwide 5G network.

T-Mobile has expanded its LTE footprint at a furious pace thanks to the addition of 600 MHz spectrum and the agility of its network team. This strategy, combined with a slew of Category 15-20 LTE smartphones, meant a tremendous boost in coverage, speeds and overall capacity. AT&T wisely used this opportunity to also upgrade the existing radio access infrastructure, including replacing the aging Alcatel-Lucent equipment with Nokia in some areas and adding the 2.3 GHz WCS spectrum for additional capacity. Over the past year, AT&T has managed to leapfrog the competition to produce the fastest download speeds across the country.ĪT&T’s addition of FirstNet spectrum meant a required maintenance visit to cell sites and the addition of brand new hardware at those locations. AT&Tĭelivering LTE service over seven licensed frequency bands and increasing the amount of seeded devices capable of four and five carrier aggregation has been paying off for AT&T. A specific look at developments related to 5G appears below. This section outlines those larger improvements. Operators continue to expand and improve their networks across the country. Major network developments over the past year

Though Sprint was the slowest operator, they showed the second largest year-over-year improvement (36.8%). T-Mobile was the second fastest (up 9.4% YoY), and Verizon Wireless the third fastest (up 9.5% YoY).

This is an increase of 45.1% over Q1-Q2 2018. in Q1-Q2 2019 with a Speed Score of 32.91 on modern devices in competitive geographies.
