Wireless electronic bilboards

Since March, Manhattan's street-level subway entrances feature wireless electronic LED billboards.

The ad content is delivered through a digital wireless system.
The content is first sent via Internet to Urban Display Network 's creative department, and uploaded to individual screens through a wireless connection. UDN can remotely administer and customize the system from anywhere.

Each screen is fitted with an omni-directional WiFi-Plus Ultra-M antenna.
