Wireless operators Verizon Wireless and Vodafone have teamed up to simulcast a Madonna performance live to mobile phone on their respective networks. It is considered the first live simulcast across multiple wireless networks.

Madonna will perform songs from her new "Hard Candy" album Wednesday April 30 at the Roseland Ballroom in New York, which Control Room is broadcasting live on the MSN Internet network. The two wireless operators will air four songs from that performance, as it happens. It is considered the first live simulcast across multiple wireless networks.

Verizon also is giving away tickets to the limited-seating event (the venue holds about 3,000). The operator tapped producer Timbaland and collaborator Justin Timberlake to create a remix of the lead single "4 Minutes." Any Verizon subscriber who buys the song, ringtone or ringback tone becomes eligible to win free tickets.

Verizon will air the live event exclusively in the U.S., while Vodafone will air it internationally in Europe, the Middle East, and Africa.

Additionally, fans can access the performance after the fact for 30 days via the Verizon VCast Performances video channel.

This is the latest in a handful of live broadcasts made available on mobile phones in recent years. It's not yet clear what the advantage of doing so is outside of the press attention gained for engaging in the relatively rare process.

Streaming live video is incredibly bandwidth intensive for mobile operators, hence the limitation to four songs. It's also of questionable value to subscribers, given the small screens of most mobile phones. Archived live performances have proven popular after the fact on demand, but the need to see a live stream from the phone is of lesser demand considering the full concert can be streamed online via the Control Room/MSN partnership.
