The eyes of soccer fans around the globe will be on Brazil June 12 when at least 3.7 million people descend on the country for the World Cup. A race is on to deploy new networks to ensure the influx of fans will be able to get on the mobile web, but the outcome is still uncertain, Eetimes.com reports.

A total of 64 matches will be held in 12 cities in new or redeveloped stadiums. Six of 12 total stadiums are still undergoing WiFi and 4G network testing -- and two are still under construction.

In part to help accommodate the extra mobile traffic, Brazil\'s regulating telecom agency, Anatel, mandated that host cities with over 500,000 people must support universal 4G coverage by May 31, 2014. Carriers that don\'t meet the deadline will lose their licenses.
