T-Mobile Low Band Spectrum LTE versus 5G April 28, 2017 07:30
For this blog post, I am going to use Allnet Insights' Mobile Carrier - Spectrum Ownership Analysis Tool to estimate the 600 MHz spectrum that T-Mobile will use to deploy LTE and what will remain available to deploy 5G.
To start this analysis, I will get T-Mobile 600 MHz and 700 MHz spectrum holdings at a county-level from the Company Analysis Module.
Using this data, we assign 10 MHz of 600 MHz spectrum to all counties where T-Mobile doesn't control 700 MHz spectrum. This spectrum assignment would provide T-Mobile with similar LTE capacity across the United States. Note that there are a few counties where T-Mobile controls enough 700 MHz spectrum to enable a 10x10 LTE channel.
The remaining 600 MHz spectrum is expected to be deployed as a 5G technology. For the map below, i have indicated 5G channel sizes that are similar to LTE channel sizes except for a 25 MHz channel size which doesn't exist in the LTE framework. This is in markets where T-Mobile controls 50 MHz of spectrum above the 5 MHz channel LTE network.
