Telecoms lobby GSMA will hold a board meeting on Friday to discuss the possible cancellation of the Mobile World Congress (MWC) in Barcelona after several big-name withdrawals because of the coronavirus outbreak.

GSMA has not made any official comment on the news, which was reported by Reuters.

MWC, scheduled to take place on Feb. 24-27, is the telecoms industry’s biggest annual gathering. A number of companies ranging from Japan’s NTT Docomo and Sony to U.S. chipmakers Intel and Nvidia had already dropped out of the four-day international telecoms conference that draws in more than 100,000 visitors.

A cancellation of the event would be a big blow for the city Barcelona.
