5G New Radio (NR) Band Analysis July 23, 2019 15:48
In July we expanded the analysis capabilities of our Mobile Carrier and Millimeter Wave - Spectrum Ownership Analysis Tools to include 5G New Radio(NR) Band Analysis for each of the 3GPP supported bandwidths in each US NR band class.
First, in the Mobile Carrier Tool, we are supporting both the uplink and downlink NR bands separately for bands that provide Frequency Division (FDD) operation. This analysis module outputs the largest channel size (for both uplink and downlink) that a carrier could deploy in their 5G/LTE uplink carrier aggregation scheme or their downlink carrier aggregation scheme. Below in the downlink analysis for AT&T you can see the maximum channel sizes for n12 band spectrum (700MHz A/B/C) versus their n29 band spectrum (700MHz D/E),which is downlink only, and their n14 band spectrum (FirstNet); for each county in the New York Cellular Market Area (CMA).
Similarly, the uplink analysis indicates the maximum uplink channel size for all of the uplink spectrum.
The n41 band spectrum that Sprint's controls (2.5GHz) is seen in the Time Division Duplex(TDD) section. The analysis tool determines the largest contiguous channel that Sprint can deploy with their leases/owned spectrum including the mid-band segment guard bands. From the results below, Sprint can configure 80MHz 5G/LTE channels in two New York counties and they can configure a 60MHz channel in one additional New York county. The remaining counties are limited to carrier aggregation of 20MHz channels.
In the Millimeter Wave - Spectrum Ownership Analysis Tool, all of the spectrum is configured to Time Division Duplex(TDD) operation. Below, you can see the different bandwidths that T-Mobile can deploy using their 24GHz or 28GHz spectrum in the New York counties. Each of the 3GPP standardized bandwidths of 400, 200, 100, and 50MHz are detailed for each spectrum band.
