HIP 58 seeks to nullify a certain gaming vector of Proof of Coverage rewards by aligning the expected range of PoC with the range of LoRaWAN devices. The current PoC mechanics allow manipulation of witness RF data at long distances and thus, we find evidence of gaming at the edges. This improvement implements a sanity check filter on Proof of Coverage and reduces the maximum range of PoC activity to 100km. The distance is based on the notion that typical devices are able to be heard 30-50km away. The distance is doubled to 100km in order to incentivize new Hotspot placements. The impact on a few legitimate witness events that are > 100km is limited as described in the dataset in the HIP.
