IMO, maybe it had something to do with the association with OneLan Services. The last quarterly report made it sound like they were getting some business opportunities as a result:
Mexico City and Cancun have both developed Wialan's wireless technology in many sites, including the Cancun Airport where fourteen million passengers are in transit annually. During the month of June 2015 a new company was formed to provide a new sales channel and local support in Mexico. The registered company name is OneLan Services commercially known as Wialan Services de Mexico. Due to the aforementioned association, Wialan is now running demos in four prestigious locations: The UNAM University, Cruz Azul soccer stadium both in Mexico City, Telcel (largest Cellular Operator in Mexico) for the project "Mexico Conectado" (a nationwide Internet initiative) and a Ferry (part of a fleet of sixty vessels) that runs from Playa del Carmen to Cozumel and Cancun to Isla de Mujeres. We expect news on these demos within the next sixty days.
