Voice Over IP Peter Cochrane

Changes will be mega-destructive… BlueTooth Ultra Wideband WiFi + WiMax MP3 Voice Over Internet Protocol (VOIP) Radio Frequency Identification (RFID) Blogs & Video Blogs …are only the start

We can only guess/imagine what our networks will be expected to support in the next decade/s…and it is the customers who decide and not the companies Peter Cochrane 1995

Network Laws - Broadcast n Connectivity = < n/2 One way only Not all are always on

Network Laws - Telephone n < n/2 Broadcast < n(n-1)/2 ~n 2 Bothways - Customer Control Availability >99%

Network Laws - Internet n < n/2 Broadcast Telephone < n(n-1)/2 ~n N …n N n Always - customer control Availability >95%

How many friends do you have…...how many people do you know? Separation People You Know 0=>30=>300 1=>900=>90,000 2=>27,000=>27,000,000 3=>810,000=>8,100,000,000 4=>24,300,000 5=>729,000,000 6=>21,870,000,000

The Telephone Network Dedicated point to point connections based on old analogue technologies spanning >100 years Reliable, dependable, well developed, well understood, but limited and in decline
