RE: QoS Issues for Transport of Multimedia Data over Cellular Wir eless

["Emad Qaddoura" <[e-mail]>]

Thanks for replying.  This will be held from 9am-2pm at 2201 BNR building in
room DIN-T22 (meet at security). Breakfast and lunch will be provided.  We
will be discussing IP Moblility research topics and Dr. Cobb's presentation.

Thanks.
