Qatar will be the smallest country ever to host the World Cup, barely a quarter of the size of the next-smallest, 1954 host Switzerland.
Of the 32 teams, 24 will have their bases within the capital city of Doha and its suburbs.
England, Germany and Belgium are among eight teams who will be based further out.
The layout is the opposite to that used in Russia four years ago, when teams were spread out across the European part of the country with some bases more than 1,300 miles (2,100 kilometers) apart and a heavy reliance on air travel to get to games.
