The Ministry of Aviation Minister, Osita Chidoka, announced the commencement of WIFI at the Lagos international airport come Monday 25, 2015. The first 20 minutes of the service will be free but charges will apply there after. Method of payment wasn't made available. Other airports are expected to follow suit but how soon, I don't know.
The ministry recently also launched tele-presence conferencing. A technological infrastructure that's expected to aid communications among the government agencies.
