No. When numerous wireless networks are set up in the show, the spectrums that carry wifi become overcrowded, particularly the 2.4 ghz spectrum. SXSW places significant investments in a wifi infrastructure throughout the Austin Convention Center that can support thousands of connections free of charge. Look for the SSID that is specific to the Trade Show. Hard-wired networks are permitted and can be ordered from the Convention Utilities Services via your exhibitor admin link.
