Countryside - 50 meters in good conditions. Goes rapidly worse if You have hills, forest or heavy rain around.

Medium density city - around 300 to 500 metres depending on the cell density. If the city is flat having only wooden houses the results are better.

Dense city - entirely dependant on cell density since travel time measurement is not usually possible due to multi path propagation. In Helsinki this would be around 100 metres and in Stockholm (center) around 200 metres due to the amount of sea around.

Very dense city with a lot of microcells You could expect to get slightly under 100 metres. If located inside a house with microcell coverage maybe even down to 20-30 metres.
