Mobility
• Mobility is the killer-app for Broadband Wireless
Access
– Mobile voice is well-established (rapidly replacing
wireline)
– Mobile multimedia data is becoming more important
• But, competition is significantly more brutal here …
Metro-scale WLANs, Mesh networks, … 4G(?)
• Multi-technology solutions will predominate - Issues related to
the real-time, QoS provisioning can be addressed but never
perfectly
• Business model for competing in this field is currently unclear
