SAR in LTE Cat M1 Band 4 is covered by LTE Cat M1 Band 66.SAR in LTE Cat M1 Band 5 is covered by LTE Cat M1 Band 26. Because the frequency range is similar, the maximum tuning limit is the same, and the channel bandwidth and other operating parameters for the smaller band is fully supported by the larger band.
