Included in the opening ceremony activities will be two panel discussions, led by senior management from both companies, which are open to the media and general public. The topics of the two panel discussions will be:
1. Wireless Data Is This the Year (Finally)?
2. Intercarrier SMS Truth or Fiction

There will also be an open house at the lab, in which visitors can participate in a facilities tour, attend demonstrations and meet with management from both TMNG and inCode.
