• HSBC Report: “The Capacity Crunch”, 2009
• AT&T/3G Americas Report, 2009
• Cisco’s Global Mobile Data Traffic Forecast, 2010
• Report from EC, 2008
The long-awaited wireless data exponential growth is underway: can we handle it?
“The iPhone is just the vanguard, with applications and content growing richer and with ever more sophisticated devices”
Mobile data to increase 40-fold between 2009 and 2014, reaching 3.6 Exabytes (2/3 video)
According to HSBC, the future sources of additional capacity are:
• More bandwidth (analog TV, new spectrum at 2.3 and 3.4 GHz)
• Offloading onto wireline via femtocells or WiFi.
• Increased cell density, at the expense of: Site procuring (permits, radiation, civil engineering) Network planning Backhaul & other operational expenses
“There is no more low-hanging fruit for the mobile industry in terms of spectral efficiency gains to drive network capacity”
• Network MIMO (or CoMP, “Coordinated Multipoint Tx/Rx”, in LTE parlance)
• Interference alignment
• Relays
• Femtocells
• Huge numbers of antennas
