Antennas in cellular networks are higher on poles to extand coverage, yes, but the key for coverage is that they are cellular. They add more antennas/base stations to cover huge areas and the whole complexity of these networks is in managing this.
- superkuh 4y agoYou've got it backwards. The key to cellular networks is that they pay money for height above terrain and thus line of sight for the cells' antennas. Otherwise it'd be infeasible. Trying to build a cellular network with the antennas at ground level is worse than a fools errand. Just look at the number of basestations required for deployal of mm-wave networks in urban cores.
- mytailorisrich 4y agoMacrocells have 'macro' coverage because they are indeed better located and more powerful (and lower frequency than mm-wave). But this tends to get smaller and smaller because of higher throughput and higher capacity demands. 5G/mm-wave/densification means more, smaller cells. In any case, the key to ubiquitous coverage is the cellular aspect: You don't build a taller mast with a more powerful transmitter. You add more cells.
