Note that LoraWan coverage is not analog to regular radio coverage, and having larger coverage can in some cases even be the worst option. E.g. a gateway on a very high tower is great for statistics and to generate a cool coverage map, but when LoraWan really takes off these gateways will be overwhelmed with messages from nodes very far away. It is also absolutely no guarantee to have any usable reception in or between buildings. It's kinda what telco's do: put LoraWan gateways on their cell towers so they can claim complete coverage of a region, with a map and all. But is that coverage actually usable? Nope, you still need a local gateway which they will happily sell to you .
