Meet the 'digital nomads' who travel the world in search of fast Wi-Fi

For these 'citizens of the world', the office can be anything from a beach hut in Brisbane to a Starbucks in Seattle, thanks to the growing prevalence of remote-based work. But roaming the globe from cafe to cafe is not without its challenges

When the average traveller lands in a city like Bangkok, Berlin, or Buenos Aires, their first step might be to drop their bags at their hotel and to log on to TripAdvisor to find out the hours of a popular tourist attraction or the best rooftop bar for happy hour.

But people like Pieter Levels are not your average traveller. A Dutch website developer, Levels has been living and working nomadically in places like Singapore, Hong Kong, Tokyo, Manila and Taipei for two years. With just a carry-on backpack, he chooses his location at will, based on a variety of factors - Wi-Fi speed, average temperature, exotic food and cost of living - that have little bearing on the work he actually does.
