Consider two LTE layers, for instance L800 and L1800 with same bandwidth. In this case, L800 will have a higher coverage as it is a lower frequency. So, the user count on L800 will be higher compared to L1800. However, the lower frequency layer also has higher interference since it has a bigger coverage radius. michael b gaffney md https://neo-performance-coaching.com
