Free wireless Internet service is expanding to Little Tokyo, Bunker Hill, the Historic Core and the Financial District. Service could be available in Little Tokyo as soon as next month, pending City Council approval. As reported by the Downtown News, the Wi-Fi program is an effort by the Community Redevelopment Agency to promote downtown neighborhoods.
