Two Mobile Revolutions…

• 1990s: mobile voice explosion– Few wires available (copper)– New wireless technology (analogue mobile)– New consumer technology (cellphones)– Pent up demand (global telephony)

Two Mobile Revolutions…

• 2010s: mobile broadband explosion– Few wires available (copper/fibre)– New wireless technology (3G/4G)– New consumer technology (smart phones)– Pent up demand (global Internet)

“Real” Mobile Broadband…

• 2000s: GPRS/3G– Limited devices: WAP, basic services– 100-1000kbps or so– IP over digital voice network (IPv4)– Single user

• 2010s: 4G/LTE– General purpose devices: full Internet access– 10-100Mbps– IP-based infrastructure (IPv4 and IPv6)– Multiple user (hotspots, Mifi, etc)– The new last mile

• Watch out for: Carrier wifi, “Wifi First”

Not “If” but “How” we will connect…

• The last mile…– Not wired – but wireless

• Wireless…– Not 3G – but 4G and carrier wifi (same device!)– And everything over IP (LTE/802.11x)

• But: Which IP?– IPv4 or IPv6?

100 million IPv4 addresses left…
