As far as I know, the most complex airport where a remote tower has been used is Ornskoldsvik in northern Sweden.
I've flown as a passenger from Ornskoldsvik - it's a tiny airport with about 75,000 pax per year in the middle of nowhere (the town is 25 mins drive from the airport with 30,000 people and the whole region has very low population density) with less than 5 departing passenger flights on most days.
Has a remote tower been trialled at any airports busier than Ornskoldsvik but quieter than London City ?
Not against the concept of remote towers but I know that as any form of new technology is scaled up to solve a problem many times more complex than where it was deployed previously, unexpected problems come to light.
After Ornskoldsvik I would have expected the vendors of this technology to be trialling at an airport of between 500k and 1m pax per year before going for a city centre airport with 4.5m pax per year
